Question

我的守则如下:

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <script src="Scripts/jquery-1.7.js" type="text/javascript"></script>
        <script>
                    $( target ).submit(function() 
                    {
                    alert( Handler for .submit() called. );
                   });
        </script>

    </head>
    <body>
        <form id="target" method="post">
            <input type="text" value="Hello there" />
            <input type="submit" value="Go" />
        </form>
        <div id="other">
        Trigger the handler
        </div>
    </body>
</html>

Answer 1

Always wrap your bind methods with the document ready function:

   <script>
   $(function () {

                $( #target ).submit(function() 
                {
                alert( Handler for .submit() called. );
               });
    });
    </script>

<>edit>/em>之所以有必要,是因为如果你在文件准备就绪之前试图对文件加以约束,那么光标的物还不存在很好的机会。当然,你可以将这笔钱改成“原始目标”的美元(“提交”)职能(......),但这不是解决问题的良好想法。如上文所述,使用现成手稿。

Answer 2

主要问题是,你的遴选人正在选择目标标,而不是目标id的成分,从而改变:

 $( target ).submit(function()

纽约总部

 $( #target ).submit(function()

你们的第二个问题是,你们应该有围绕OMM准备活动总结的贵重法律。

Answer 3

您错了一张标志。

<script>
                    $( #target ).submit(function() 
                    {
                    alert( Handler for .submit() called. );
                   });
        </script>

Answer 4

你们需要tag子(#),供选择。

$( #target ).submit(function() 
...

见。

Answer 5

Because when this code is executed there is no target yet. Use .ready(). Also it should be $( #target ) as id selectors should be prefixed with #.

$(function(){
    $( #target ).submit(function() 
    {
        alert( Handler for .submit() called. );
    });
}

Answer 6

<代码>#在选任人中缺失。

$( #target ).submit(function(){ });

Answer 7

Use it this way:

 <script>
           $(document).ready(function () {

               $( #target ).submit(function () {
                   alert( Handler for .submit() called. );
               });
           });
    </script>
