解决ztree搜索中多级菜单展示不全问题

解决ztree搜索中多级菜单展示不全问题

ztree 官网的中的 Search Nodes 例子中，所有菜单都是连着的，如果出现某个菜单下无子节点，那么在搜索时，此节点便不会自动展开，这里给出对应的增强版代码

var setting = {

data: {

key: {

title: "t"

},

simpleData: {

enable: true

}

},

view: {

fontcss: getFontCss

}

};

var zNodes =[

{ id:1, pId:0, name:"系统参数",open:true},

{ id:11, pId:1, name:"通用参数"},

{ id:111, pId:11, name:"状态A"},

{ id:112, pId:11, name:"状态B"},

{ id:12, pId:1, name:"日志"},

{ id:121, pId:12, name:"操作类型"},

{ id:122, pId:12, name:"操作结果"},

{ id:1221, pId:122, name:"操作结果1"},

{ id:1222, pId:122, name:"操作结果2"},

{ id:12221, pId:1222, name:"操作结果21"},

{ id:12222, pId:1222, name:"操作结果22"},

{ id:12223, pId:1222, name:"操作结果23"},

{ id:2, pId:0, name:"业务参数",open:true},

{ id:21, pId:2, name:"工单类型"qEzntmGN},

{ id:22, pId:2, name:"监控类型"},

{ id:23, pId:22, name:"监控子类型1"},

{ id:24, pId:22, name:"监控子类型2"},

{ id:25, pId:24, name:"监控子子类型1"},

{ iqEzntmGNd:26, pId:24, name:"监控子子类型2"},

];

var lastValue = '', nodeList = [], fontCss = {};

function searchNode(e) {

var zTree = $.fn.zTree.getZTreeObj("treeDemo");

var value = $.trim(key.val());

lastValue = value;

//zTree.expandAll(true);

$('#treeDemo').html("");

$.fn.zTree.init($("#treeDemo"), setting, zNodes);

if (value != "") {

nodeList = zTree.getNodesByParamFuzzy("name", value);

} else {

nodeList = zTree.getNodesByParamFuzzy("name", "|||||||||||||||");

}

updateNodes(true);

}

var parentNode = [];

function updateNodes(highlight) {http://

var zTree = $.fn.zTree.getZTreeObj("treeDemo");

parentNode = [];

for( var i=0, l=nodeList.length; i

nodeList[i].highlight = highlight;

zTree.updateNode(http://nodeList[i]);

if (!nodeList[i].isParent && !parentNode.contains(nodeList[i].getParentNode().pId)) {

zTree.expandNode(nodeList[i].getParentNode(), true, true, true);

parentNode.push(nodeList[i].getParentNode().pId);

console.log(nodeList[i].getParentNode().pId);

} else {

zTree.expandNode(nodeList[i], true, true, true);

}

}

console.log(parentNode);

}

Array.prototype.contains = function (obj) {

var i = this.length;

while (i--) {

if (this[i] === obj) {

return true;

}

}

return false;

}

function getFontCss(treeId, treeNode) {

return (!!treeNode.highlight) ? {color:"#A60000", "font-weight":"bold"} : {color:"#333", "font-weight":"normal"};

}

var key;

$(document).ready(function(){

$.fn.zTree.init($("#treeDemo"), setting, zNodes);

key = $("#search_name");

key.bind("blur", searchNode);

});
