本文實例介紹了jQuery Validate表單驗證,主要是利用jquery.metadata.js將校驗規則直接寫在class屬性裡面並定義錯誤訊息的提示,分享給大家供大家參考,具體內容如下
1、增加一個另外一個外掛程式jquery.metadata.js 並把校驗規則寫在控制項裡面。
2、需要改寫觸發校驗的方式。
$("#commentForm").validate({meta: "validate"});
3、詳細程式碼如下:
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>jQuery表单验证插件----利用jquery.metadata.js将校验规则写到控件中</title> <script src="../../scripts/jquery-1.3.1.js" type="text/javascript"></script> <script src="lib/jquery.validate.js" type="text/javascript"></script> <script src="lib/jquery.metadata.js" type="text/javascript"></script> <style type="text/css"> * { font-family: Verdana; font-size: 96%; } label { width: 10em; float: left; } label.error { float: none; color: red; padding-left: .5em; vertical-align: top; } p { clear: both; } .submit { margin-left: 12em; } em { font-weight: bold; padding-right: 1em; vertical-align: top; } </style> <script type="text/javascript"> $(document).ready(function(){ $("#commentForm").validate({meta: "validate"}); }); </script> </head> <body> <form class="cmxform" id="commentForm" method="get" action=""> <fieldset> <legend>jQuery表单验证插件----利用jquery.metadata.js将校验规则写到控件中</legend> <p> <label for="cusername">姓名</label> <em>*</em><input id="cusername" name="username" size="25" class="{validate:{required:true, minlength:2}}" /> </p> <p> <label for="cemail">电子邮件</label> <em>*</em><input id="cemail" name="email" size="25" class="{validate:{required:true, email:true}}" /> </p> <p> <label for="curl">网址</label> <em> </em><input id="curl" name="url" size="25" value="" class="{validate:{url:true}}" /> </p> <p> <label for="ccomment">你的评论</label> <em>*</em><textarea id="ccomment" name="comment" cols="22" class="{validate:{required:true}}" ></textarea> </p> <p> <input class="submit" type="submit" value="提交"/> </p> </fieldset> </form> </body> </html>
預設校驗規則:
messages: { required: "This field is required.", remote: "Please fix this field.", email: "Please enter a valid email address.", url: "Please enter a valid URL.", date: "Please enter a valid date.", dateISO: "Please enter a valid date (ISO).", dateDE: "Bitte geben Sie ein g眉ltiges Datum ein.", number: "Please enter a valid number.", numberDE: "Bitte geben Sie eine Nummer ein.", digits: "Please enter only digits", creditcard: "Please enter a valid credit card number.", equalTo: "Please enter the same value again.", accept: "Please enter a value with a valid extension.", maxlength: $.validator.format("Please enter no more than {0} characters."), minlength: $.validator.format("Please enter at least {0} characters."), rangelength: $.validator.format("Please enter a value between {0} and {1} characters long."), range: $.validator.format("Please enter a value between {0} and {1}."), max: $.validator.format("Please enter a value less than or equal to {0}."), min: $.validator.format("Please enter a value greater than or equal to {0}.") },
class="{required:true,minlength:5,messages:{required:'请输入内容'}}"
class="{required:true,minlength:5,equalTo:'#password'}"
<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>jQuery表单验证插件----利用jquery.metadata.js将校验规则写到控件中(2)</title> <script src="../../scripts/jquery-1.3.1.js" type="text/javascript"></script> <script src="lib/jquery.validate.js" type="text/javascript"></script> <script src="lib/jquery.metadata.js" type="text/javascript"></script> <style type="text/css"> * { font-family: Verdana; font-size: 96%; } label { width: 10em; float: left; } label.error { float: none; color: red; padding-left: .5em; vertical-align: top; } p { clear: both; } .submit { margin-left: 12em; } em { font-weight: bold; padding-right: 1em; vertical-align: top; } </style> <script type="text/javascript"> $(document).ready(function(){ $("#commentForm").validate({meta: "validate"}); }); </script> </head> <body> <form class="cmxform" id="commentForm" method="get" action=""> <fieldset> <legend>jQuery表单验证插件----利用jquery.metadata.js将校验规则写到控件中(2)</legend> <p> <label for="cusername">姓名</label> <em>*</em><input id="cusername" name="username" size="25" class="{validate:{required:true, minlength:2, messages:{required:'请输入姓名', minlength:'请至少输入两个字符'}}}" /> </p> <p> <label for="cemail">电子邮件</label> <em>*</em><input id="cemail" name="email" size="25" class="{validate:{required:true, email:true, messages:{required:'请输入电子邮件', email:'请检查电子邮件的格式'}}}" /> </p> <p> <label for="curl">网址</label> <em> </em><input id="curl" name="url" size="25" value="" class="{validate:{url:true, messages:{url:'请检查网址的格式'}}}" /> </p> <p> <label for="ccomment">你的评论</label> <em>*</em><textarea id="ccomment" name="comment" cols="22" class="{validate:{required:true, messages:{required:'请输入您的评论'}}}" ></textarea> </p> <p> <input class="submit" type="submit" value="提交"/> </p> </fieldset> </form> </body> </html>可以使用以下的方法,修改提示內容:
7、效果如下:
