easyui

一，引言

工作的需要，做了3年的wpf(mvvm)……，又因为项目的需求，回归到web的开发。

3 years ago，vue是我三年前没用过的玩意儿。

3 years ago，bootstrap组件没现在成熟。

3 years ago，font awesome的普及度没有现在高。

3 years ago，ui组件的选择也没有现在多。

二，项目的前端（easyui模板订制）

整个项目采用了oracle  + dapper  + castle + mvc + easyui的技术结合，本篇博客重点介绍easyui。

easyui的默认风格看久了很容易产生视觉疲劳，在这个项目中，我个性化订制风格。

订制easyui模板的工作量是挺大的，我用了一个偷懒的方法，花了几百块钱在网上买了几个easyui的皮肤，然后对这些皮肤，进行优化和重构。

money比较紧的同学，可以去下载easyui的免费皮肤。

三，easyui-datagrid的基本使用：

1，加载数据

a，通过post，url的方法向后端请求数据，如图所示：

$('#List').datagrid({

title: "交易公司",

loadMsg: '@CommonResource.Processing',

toolbar: '#tb',

width: "100%",

height: "100%",

//idField:"ID",

//data: getData(),

url: "@Url.Action("GetList")",

methord: 'post',

rownumbers: true,

autoRowHeight: false,

fit: true,

//fitColumns: true,

striped: true, //奇偶行

singleSelect: true,//单选模式

checkOnSelect: false,

selectOnCheck: false,

collapsible: true,

pagination: true,

pageNumber: 1,

pageSize: 10,

pageList: [10, 20],

queryParams: { },

columns: [[

{ field: 'Company_Name', title: '公司名称', width: 100, sortable: false },

{ field: 'Abbreviation', title: '简称', width: 100, sortable: false },

{ field: 'Business_Address', title: '经营地址', width: 100, sortable: false },

{ field: 'Registered_Address', title: '注册地址', width: 100, sortable: false },

{ field: 'Tel', title: '电话', width: 100, sortable: false },

{ field: 'Fax', title: '传真', width: 100, sortable: false },

{ field: 'Contactor', title: '联系人', width: 100, sortable: false },

{ field: 'Payment', title: '结算方式', width: 100, sortable: false },

{ field: 'Beneficiary_Name', title: '开户名称', width: 100, sortable: false },

{ field: 'Beneficiary_Address', title: '开户地址', width: 100, sortable: false },

{ field: 'Advising_Bank', title: '通知行', width: 100, sortable: false },

{ field: 'Bank_Address', title: '银行地址', width: 100, sortable: false },

{ field: 'Swift_Code', title: '银行代码', width: 100, sortable: false },

{ field: 'Beneficiary_Account', title: '银行账户', width: 100, sortable: false },

{ field: 'Company_Chop', title: '电子章', width: 100, sortable: false },

{ field: 'Send_Url', title: '发件邮箱链接', width: 100, sortable: false },

{ field: 'Send_Email', title: '发件人邮箱', width: 100, sortable: false },

{ field: 'Remark', title: '备注', width: 100, sortable: false },

{ field: 'Created_By', title: '创建人', width: 100, sortable: false },

{ field: 'Creation_Date', title: '创建日期', width: 100, sortable: false },

{ field: 'Modify_By', title: '修改人', width: 100, sortable: false },

{ field: 'Modify_Date', title: '修改日期', width: 100, sortable: false },

]],

});

});

b，先定义好了datagrid的属性以及列，再通过loadData的方法设置datagrid的数据

$('#Detail').datagrid({

loadMsg: '@CommonResource.Processing',

toolbar: '#tb',

width: "100%",

height: "100%",

//data: [],

rownumbers: true,

autoRowHeight: false,

fit: true,

fitColumns: true,

striped: true,

singleSelect: true,

collapsible: false,

pagination: false,

queryParams: { },

columns: [[

{ field: 'Country_Name', title: '国家名称', width: 100, sortable: false },

{ field: 'Item_Number', title: '物料编码', width: 100, sortable: false },

]],

});

var returnData = jsON.parse(response.data);

$('#Detail').datagrid("loadData", returnData);

2，合并单元格

有时候用户需要如下图的效果

可以在datagrid的onLoadSuccess事件里增加如下代码：

onLoadSuccess: function (data) {

//var opts = $('#List').datagrid('getColumnFields');

var opts = new Array("Item_Number", "Country_Name", "Item_Desc", "Item_Desc_En", "Item_Type", "Unit", "Hs_Code", "Destination_Code", "Status", "Remark", "Create_User", "Create_Date");

var rowsCount = data.rows.length;

var mark = 1;

for (var j = 1; j < rowsCount; j++)

{

var preCellVal = data.rows[j - 1]["Material_Id"];

var currentCellVal = data.rows[j]["Material_Id"];

if (preCellVal == currentCellVal) {

mark += 1;

for (var c = 0; c < opts.length; c++) {

var columnName = opts[c];

$(this).datagrid('mergeCells', {

field: columnName,

index: j + 1 - mark,

rowspan: mark

});

}

}

else {

mark = 1;

}

}

},

3，行，列变色

针对这样的行，列变色效果：

a，行变色

$('#Detail').datagrid({

loadMsg: '@CommonResource.Processing',

toolbar: '#tb',

width: "100%",

height: "100%",

url: "@Url.Action("GetLines")",

methord: 'post',

rownumbers: true,

autoRowHeight: false,

fit: true,

fitColumns: true,

striped: true,

singleSelect: true,

collapsible: false,

pagination: false,

queryParams: { hid: $("#Hid").val() },

columns: [[

{ field: 'Material_No', title: '物料号', width: 100, sortable: false },

{ field: 'Description', title: '中文描述', width: 100, sortable: false },

{ field: 'En_Description', title: '英文描述', width: 100, sortable: false },

{ field: 'Unit', title: '单位', width: 100, sortable: false },

{ field: 'Quantity', title: '工单数量', width: 100, sortable: false },

{ field: 'Total_Actual_Send_Quantity', title: '已出货数量', width: 100, sortable: false },

{ field: 'Remark', title: '备注', width: 100, sortable: false },

]],

rowStyler: function (index, row) {

if (row.Quantity == 0) {

return 'background-color:pink;color:blue;font-weight:bold;';

}

},

});

b，列变色

$('#Detail').datagrid({

loadMsg: '@CommonResource.Processing',

width: "100%",

height: "100%",

data: [],

rownumbers: true,

autoRowHeight: false,

fit: true,

fitColumns: true,

striped: true,

singleSelect: true,

checkOnSelect: false,

selectOnCheck: false,

collapsible: false,

pagination: false,

queryParams: {},

columns: [[

{ field: 'sel', checkbox: true },

{ field: 'Material_No', title: '物料号', width: 80, sortable: false },

{ field: 'Description', title: '中文描述', width: 80, sortable: false },

{ field: 'Unit', title: '单位', width: 80, sortable: false },

{ field: 'Quantity', title: '工单数量', width: 80, sortable: false },

{ field: 'Total_Actual_Send_Quantity', title: '已出货数量', width: 80, sortable: false },

{ field: 'Remain_Quantity', title: '剩余数量', width: 80, sortable: false },

{

field: 'Actual_Send_Quantity', title: '本次出货', width: 80, sortable: false,

editor: { type: 'numberbox', options: { required: true, min: 0 }, },

styler: function (value, row, index) {

return 'background-color:#ecffff;';

},

},

{

field: 'Remark', title: '备注', width: 80, sortable: false,

editor: { type: 'textbox', options: { validType: 'length[1,20]' }, },

styler: function (value, row, index) {

return 'background-color:#ecffff;';

},

},

]],

4，为datagrid添加工具条

如下效果的工具条，是通过datagrid的 toolbar 属性来指定，要留意的是toolbar的控件名称需要加上#符号。

html代码：

  查询条件

@Html.ToolButton(string.Format(@"  {0}", @CommonResource.Add), ActionCode.Create)

@Html.ToolButton(string.Format(@"  {0}", @CommonResource.Edit), ActionCode.Edit)

@Html.ToolButton(string.Format(@"  {0}", @CommonResource.Delete), ActionCode.Delete)

js代码：

5，做增，删，改操作

a,为datagrid增加一行

function addCallBack(data) {

$('#List').datagrid('insertRow', {

index: 0,

row: data,

});

layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });

}

b,为datagrid编辑一行

function editCallBack(data) {

var selectData = $('#List').datagrid('getSelectedgEAWKpLv');

var selectIndex = $('#List').datagrid('getRowIndex', selectData);

$('#List').datagrid('updateRow', {

index: selectIndex,

row: data,

});

layer.msg('@CommonResource.ModifySuccess', { icon: 1, time: 1000 });

}

c,为datagrid删除一行

$("#btnLineDelete").click(function () {

var row = $('#Detail').treegrid('getSelected');

if (row != null) {

var rowIndex = $('#Detail').datagrid('getRowIndex', row);

$('#Detail').datagrid('deleteRow', rowIndex);

layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });

}

else {

layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

}

});

d,treegrid的操作方法略有区别，附上源码：

function addCallBack(data) {

var row = $('#List').treegrid('getSelected');

$('#List').treegrid('append', {

parent: data.Parent_Id,

data: [{

Id: data.Id,

Name: data.Name,

En_Name:data.En_Name,

Code: data.Code,

Enable: data.Enable,

Sort: data.Sort,

}]

});

layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });

}

function editCallBack(data) {

var row = $('#List').treegrid('getSelected');

$('#List').treegrid('update', {

id: row.Id,

row: {

Name: data.Name,

En_Name: data.En_Name,

Code: data.Code,

Enable: data.Enable,

Sort: data.Sort,

}

});

layer.msg('@CommonResource.ModifySuccess', { icon: 1, time: 1000 });

}

$("#btnDelete").click(function () {

var row = $('#List').treegrid('getSelected');

if (row != null) {

layer.confirm('@CommonResource.ConfirmDelete', {

btn: ['@CommonResource.Sure', '@CommonResource.Cancel'],

shadeClose: true,

}, function () {

if (row.ChildCount == 0 || typeof (row.ChildCount) == 'undefined') {

$.post("@Url.Action("Delete")/" + row.Id, function (data) {

if (data == "1") {

$("#List").treegrid('remove', row.Id);

layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });

}

else {

layer.msg('@CommonResource.DeleteFailed', { icon: 2, time: 1000 });

}

}, "json");

}

else {

layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

}

}, function () {

});

}

else {

layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

}

});

6，编辑单元格

具体代码实现

var taxTypeList = JSON.parse($("#taxTypeList").val());

var manufactureList = JSON.parse($("#manufactureList").val());

$.extend($.fn.datagrid.methods, {

editCell: function (jq, param) {

return jq.each(function () {

var opts = $(this).datagrid('options');

var fields = $(this).datagrid('getColumnFields', true).concat($(this).datagrid('getColumnFields'));

for (var i = 0; i < fields.length; i++) {

var col = $(this).datagrid('getColumnOption', fields[i]);

col.editor1 = col.editor;

if (fields[i] != param.field) {

col.editor gEAWKpLv= null;

}

}

$(this).datagrid('beginEdit', param.index);

for (var i = 0; i < fields.length; i++) {

var col = $(this).datagrid('getColumnOption', fields[i]);

col.editor = col.editor1;

}

});

}

});

var editIndex = -1;

function endEditCal() {

if (editIndex == -1) {

return true;

}

if ($('#Detail').datagrid('validateRow', editIndex)) {

$('#Detail').datagrid('endEdit', editIndex);

editIndex = -1;

return true;

}

else {

return false;

}

}

$('#Detail').datagrid({

loadMsg: '@CommonResource.Processing',

toolbar: '#tb',

width: "100%",

height: "100%",

formatter: function (value) {

for (var i = 0; i < manufactureList.length; i++) {

if (manufactureList[i].Key == value) return manufactureList[i].Value;

}

return value;

},

editor: {

type: 'combobox',

options: {

valueField: 'Key',

textField: 'Value',

data: manufactureList,

required: true,

panelHeight: "auto",

editable:false,

}

},

},

{

field: 'Tax_Type', title: '税别', width: 100, sortable: false,

formatter: function (value) {

for (var i = 0; i < taxTypeList.length; i++) {

if (taxTypeList[i].Key == value) return taxTypeList[i].Value;

}

return value;

},

valueField: 'Key',

textField: 'Value',

data: taxTypeList,

required: true,

panelHeight: "auto",

editable: false,

}

},

},

{ field: 'Tax_Bcd', title: 'BCD', width: 100, sortable: false, editor: { type: 'numberbox', options: { required: true, suffix: '%', precision: 2, min: 0, max: 100, } } },

{ field: 'Tax_Cess', title: 'CESS', width: 100, sortable: false, editor: { type: 'numberbox', options: { required: true, suffix: '%', precision: 2, min: 0, max: 100, } } },

{ field: 'Tax_Igst', title: 'IGST', width: 100, sortable: false, editor: { type: 'numberbox', options: { required: true, suffix: '%', precision: 2, min: 0, max: 100, } } },

]],

@if (Request.Params["Operate"] != "View")

{

onClickCell: function (index, field, value) {

if (endEditCal()) {

$(this).datagrid('selectRow', index).datagrid('editCell', { index: index, field: field }); //编辑一个单元格

//$(this).datagrid('beginEdit', index); //编辑一行

editIndex = index;

}

else {

layer.msg('当前行的数据编辑有误', { icon: 2, time: 1000 });

}

},

onAfterEdit: function (index, row, changes) {

var rowData = $(this).datagrid('getData').rows[index];

$('#Detail').datagrid('updateRow', {

index: index,

row: {},

});

},

onLoadSuccess: function (data) {

for (var index = 0; index < data.rows.length; index++) {

$(this).datagrid('beginEdit', index);

}

},

}

});

$("#btnLineCreate").click(function () {

if (endEditCal()) {

editIndex = 0;

$('#Detail').datagrid('insertRow', {

index: editIndex,

row: {},

});

$('#Detail').datagrid('selectRow', editIndex);

$('#Detail').datagrid('beginEdit', editIndex);

}

else {

layer.msg('当前行的数据编辑有误', { icon: 2, time: 1000 });

}

});

$("#btnLineDelete").click(function () {

var row = $('#Detail').treegrid('getSelected');

if (row != null) {

var rowIndex = $('#Detail').datagrid('getRowIndex', row);

$('#Detail').datagrid('deleteRow', rowIndex);

layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });

}

else {

layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

}

});

$("#btnSave").click(function () {

var summaryValidate = true;

var rows = $("#Detail").datagrid("getRows");

$(rows).each(function (index, itemData) {

if ($('#Detail').datagrid('validateRow', index)) {

$('#Detail').datagrid('endEdit', index);

}

else {

summaryValidate = false;

return false;

}

});

if (summaryValidate) {

if (rows.length == 2) {

$("#MaterialDetailListStr").val(JSON.stringify(rows));

}

else {

layer.msg('税别,用途应该设置为2行数据', { icon: 2, time: 1000 });

return false;

}

}

else {

layer.msg('当前表单数据编辑有误', { icon: 2, time: 1000 });

return false;

}

var check = $('form').form('validate');

if (check) {

$.ajax({

url: "@Url.Action("CreateMaterial")",

type: "Post",

data: $("form").serialize(),

dataType: "json",

success: function (data) {

if (data.Key == "1") {

parent.$("#List").datagrid('reload');

var index = parent.layer.getFrameIndex(window.name);

parent.layer.close(index);

parent.layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });

}

else {

layer.msg("物料编号'" + data.Value.Item_Number + "'在数据库中已添加", { icon: 2, time: 1000 });

}

},

error: function (jqXHR, textStatus, errorThrown) {

layer.msg('@CommonResource.AddFailed', { icon: 2, time: 1000 });

}

});

}

});

7，重置datagrid布局  $('#List').datagrid("resize");

$(function () {

$(".more").click(function () {

$(this).closest(".conditions").siblings().toggleClass("hide");

$('#List').datagrid("resize");

});

})
