我的代码在 IE7 中有效，但在需要对象时出现错误，并且在 chrome 和 firefox 中无效。请帮我。下面是我的代码 IE7 浏览器从 jquery 函数的开始显示错误，但我能够继续。但是在 chrome 和 safari 中，提交按钮和 Validate() 函数不起作用。

            <link rel="stylesheet" type="text/css" href="css/style.css" />
            <script src="js/cufon-yui.js" type="text/javascript"></script>
            <script src="js/ChunkFive_400.font.js" type="text/javascript"></script>
            <script type="text/javascript">
            Cufon.replace('h1',{ textShadow: '1px 1px #fff'});
            Cufon.replace('h2',{ textShadow: '1px 1px #fff'});
            Cufon.replace('h3',{ textShadow: '1px 1px #000'});
            Cufon.replace('.back');
            </script>
            <script type="text/javascript">
            function validate(){
            var Uname=document.getElementById("username")
            if(Uname.value==""||Uname.value==null){
            alert("Enter Your User Name")
            Uname.focus()
            return false
            }
            if(Uname.value.length<6){
            alert("Min-6 characters for your UserName")
            Uname.focus()
            return false
            }
            var pass=document.getElementById("password")

您的 for classes onSubmit 缺少结束双引号。

 <form class="login active" onSubmit="return validate()**"** action="login.php" method="post">

这将解决您的问题并触发事件。
