封装好的一个万能检测表单的方法

检测表单中的不能为空(.notnull)的验证

作用:一对form标签下有多个(包括一个)表单需要提交时,使用js准确的判断当前按钮对那些元素做判断

用法:在form标签下 找到当前 表单的容器 给予class="form",当前表单的提交按钮给予 class="check"

 需要验证为空的元素给予class="notnull" nullmsg="xx不能为空!"提示,需要进行逻辑判断的表单给予class="need"

 判断的类型给予 class="num"(只能是数字) 验证的提示 logicmsg="XX只能是数字"

给予class="errorMessage"显示错误信息块

 给予class="warn"显示错误信息

 未使用js面向对象编程

 逻辑判断,不传入need标识,直接给出正则表达式属性(自定义)regex="/^\d$/"  做出判断

在外部实现

 Global.submitCallback button回调函数

 Global.confirmCallback confirm回调函数;

 需要改进的地方:

复制代码 代码如下:

//$(document).ready(

//    function () {

//        $("form").find(".notnull").bind({

//            focus: function () {

//                if ($(this).attr("value") == this.defaultValue) {

//                    $(this).attr("value", "");

//                }

kTnlxHAulS//            },

//            blur: function () {

//                if ($(this).attr("value") == "") {

//                    $(this).attr("value", this.defaultValue);

//                }
