jQuery的validate验证功能十分强大,但是能够自定义验证方法更具有灵活性,所以我只是把自定义的说明一下。
添加自定义方法是使用jquery的jQuery.validator.addMethod方法,这个方法的完整定义如下:
jQuery.validator.addMethod("myValidateName", function(value, element, param) { //myValidateName是自己定义的验证方法值 //value是指当前校验域的值 //element是指当前检验的域 //param是指在rules中设定的参数 },$.validator.format("xxx"));
定义完之后,就可以通过在页面中声明和调用了。调用方法如下:
var validator = $("#formName").validate({//formName是form的名字 submitHandler: function(form) { //提交时候调用的方法 formSubmit();//调用成功后的处理函数 } , rules: { inputName1: "myValidateName",//如果只用一个验证方式的话,需要用引号标记上,而且这种方式是认为强制执行的,也就是一定要验证的 inputName2: {//如果想使用多种验证方式,就需要使用花括号标记上,且逗号隔开,记住:最后一项不要有逗号 myValidateName1: true,//这种是强制执行的验证 myValidateName2: function(){if(某条件满足){return true;}else{return false;}},//这种根据条件判断要不要验证,更佳的灵活,用在多条件输入的时候极为方便 myValidateName3: [//使用方括号的是对于普通验证的更佳高级方法,这种方法也十分好用 function(){if(某条件满足){return true;}else{return false;}},//同上,验证条件判断,条件不满足,本验证就不生效 rangeValue1,//阈值控制值,这个值可以有任意多个,就看你的验证方法中是怎样声明的了 rangeValue2//阈值控制值 ] } }, messages: {//验证到不合法的值的提示信息,如果不加这部分,就会执行你声明函数的时候的默认提示:“xxx”,就是在$.validator.format("xxx"));中声明的那个提示 inputName1: "AAA",//这种写法是将所有验证不通过的全部提示AAA inputName2: {//这种就是更佳详细的提示,当然也可以使用上面的这种方式,无论myValidateName1,2还是3,只要有不通过的,都会提示同一条信息。 myValidateName1:"BBB",//但是如果详细些的提示,就需要用花括号标记上,并且内部用逗号隔开,且最后一个后面不能有逗号,就相当于使用数组的方式 myValidateName2:"CCC", myValidateName3:"DDD"//这里后面不能有逗号了,不然在有些浏览器中会报错 } }, errorPlacement: function(error, element) {//这里定义的是出错或者叫提示信息出现的位置 error.insertAfter(element.parent().find('label:first'));//这句话的意思就是说,在验证不通过的那个标签上面的父节点开始向下找到第一个lable标签的后面,进行插入 }, //就是这样,如下面: //<div> // <lable>mylablename</lable> 这里是你定义的一个lable标签 // <input name="inputName1" type="text" /> //</div> //如果验证不通过,那么就会从名字为inputName1的标签开始查找它的父标签,也就是div,然后再从div开始乡下找到第一个lable标签,就是mylablename那行,然后再在这行之后进行插入错误信息 //执行之后,大概就是下面的样子: //<div> // <lable>mylablename</lable> 这里是你定义的一个lable标签 // <lable>AAA</lable>这里是你验证不通过时的提示信息 // <input name="inputName1" type="text" /> //</div> success: function(label) { // set as text for IE label.html(" ").addClass("ok");//这个就是如果验证通过了,就再在提示的那行lable标签中添加名字为ok的class类,用于改变css样式,至于名字随便起 } });
下面举一个具体的例子
首先定义自己的验证方法,定义到myvalidate.js中,内容如下
$(document).ready(function(){ //验证IP地址 jQuery.validator.addMethod("isIP", function(value, element, param) { if ( !this.depend(param, element) )//这个判断必须要加上,这个是判断是否要执行这个检测,就是对于rules中定义的isIP后面的条件的判断,如果不满足,就不再验证了 return "dependency-mismatch"; //所以我说,这里必须要加上,其实也不是必须,但是这样会十分灵活,根据你的意愿让它到底何时验证 var reg = new RegExp(getReg("ip"),"i"); //这里是一个正则表达式,具体是怎样的,就不列出来了,不懂的,自己百度一下正则表达式,很简单的 return this.optional(element) || (reg.test(value)); //前面optional这部分我也不清楚是啥意思,但是看官方的js脚本都是加上的,那么咱们也照样加上, //然后后面的这部分才是你真正的判断,注意:只有return false的时候,才会显示你的提示,如果返回的是true,那么就进入到了前面success函数哪里 }, $.validator.format("not IP"));//这里就是如果没有通过验证要提示给用户的信息,显示位置由你声明调用的时候规定,在前文中有说明 //验证在一定范围内的数值,这个例子就比较麻烦的那个,也就是前面说的是用方括号的那个 jQuery.validator.addMethod("isMyRange", function(value, element, param) { if ( !this.depend(param[0], element) )//这里的param[0],就代表调用定义中的方括号中的第一个元素,如果按照前面myValidateName3的例子的话,它就是对应function那一行 return "dependency-mismatch"; var reg = new RegExp(getReg("integer65535"),"i"); //因为是判断数值,所以首先用正则表达式判断一下是不是数值,别验证半天,结果人家用户根本就没输入数值 return this.optional(element) || (reg.test(value) && value >= param[1] && value <= param[2]);//这里的param[1]和param[2]就分别代表着第二和第三个元素,也就是rangeValue1和rangeValue2,那么这个验证的目的就是验证在rangeValue1和rangeValue2之间的数值 }, $.validator.format("请输入 {1} 和 {2} 之间的数值"));//这里也需要注意,其中的{1}和{2}是分别代表你定义的rangeValue1和rangeValue2这两个值,其实,这里的{1}和{2}就是你在rulse中的那个方括号中定义的元素的下标,有过c语言或者程序开发的肯定再熟悉不过了,对,就是数组嘛 });
下面在html页面中添加定义
比如我有个页面,叫test.html,内容如下:
<html> <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script><!-- 先要包含jquery库 --> <script type="text/javascript" src="js/jquery.validate.js"></script><!-- 还要包含jquery.validate库 --> <script type="text/javascript" src="js/myvalidate"></script><!-- 最后才是你自己定义的库 --> <script type="text/javascript"> $(document).ready(function(){//开始声明验证方法 var validator = $("#myform").validate({ submitHandler: function(form) { //提交时候调用的方法 formSubmit(); } , rules: { myipaddr: { isIP: "#myradio_on:checked"//这里就是说当id为myradio_on的radio元素被选中的时候开始验证 }, mycount: { isMyRange: [ "#myradio_on:checked",//同上 200, 800 ] } }, //这里我省略掉了message,使用默认的提示,也就是我定义验证方法时给出的提示 // the errorPlacement has to take the layout into account errorPlacement: function(error, element) { error.insertAfter(element.parent().find('label:first')); }, // set new class to error-labels to indicate valid fields success: function(label) { // set as text for IE label.html(" ").addClass("ok"); } }); }); </script> <body> <form name="myform" id="myform" method="post" action="myaction.html"> <div> <p> <label>是否验证</label><br/> <input type="radio" name="validate" id="validate_on"/> <input type="radio" name="validate" id="myradio_off"/> <label for="myradio_off">算了</label> </p> </div> <div> <p> <label>IP验证</label><br/> <input type="text" name="myipaddr" id="myipaddr"/> </p> </div> <div> <p> <label>Count验证</label><br/> <input type="text" name="mycount" id="mycount"/> </p> </div> </form> </body> </html>
到此一个完整的验证就出来了,你可以试一下,现在感觉确实很强大,如果有错误,希望大家指正,相互学习
下面附注一下jquery.validate.js文件中的内容,有部分有些改动,并非原版官方的,但是绝大多数都是一样的,大家可以看看,相信一定能学到很多东西
