Jquery .Click函数不能正常工作。

I'm working on a K-Mapping application for Electrical Engineering. However, I'm stuck on a single click function.

我正在研究一个电子工程的K-Mapping应用程序。但是，我被一个单击函数卡住了。

if(jQuery)
$(document).ready(function(){
$('a').click(function(){
        alert("Evaluate Click Works");
        var match = $(mintermIndexes).compare(ArrayOfEight);
        if(match){
            alert("All squares have been checked");
        }   
        return false;
});
});

This is HTML,

这是HTML,

  <div id="body">

        <input id="Clear" value="Clear Form" type="submit" />
        <a id="Evaluate" href="#" >Evaluate</a>

    </div>

I really could use some help, I did share the only code that I think there is a problem. Please share your thoughts on how to fix this issue. Thanks.

我真的需要一些帮助，我分享了我认为唯一有问题的代码。请分享你对如何解决这个问题的想法。谢谢。

p.s : I tried almost every possible selector, but still nothing. There is no respond when i hit the link.

p。我试了几乎所有可能的选择器，但还是没有。当我点击链接时，没有回应。

EDIT: Changing the referencing order in the head tag worked, i.e i changed the order of my jquery app and jquery reference order. Thanks for the help anyway.

编辑:改变head标签中引用顺序的工作，我。e我改变了jquery应用程序的顺序和jquery参考顺序。谢谢你的帮助。

I always encounter this problem. My solution is to put the script below the tag I want to manage. like this:

我总是遇到这个问题。我的解决方案是将脚本放在我想要管理的标记下面。是这样的:

<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
</head>
<body>
       <input id="Clear" value="Clear Form" type="submit" />
       <a id="Evaluate" href="#" >Evaluate</a>

<script type="text/javascript">
    $('a').click(function(){
           alert("Evaluate Click Works");
           var match = $(mintermIndexes).compare(ArrayOfEight);
           if(match){
               alert("All squares have been checked");
       }   
    });
</script>
</body>
</html>

explanation:

解释:

you need to make sure that the "tag" is loaded first

您需要确保首先加载“标记”。

Works fine:

工作正常:

Try removing the if (jQuery)

尝试删除if (jQuery)

Also, have you correctly referenced the jQuery scripts?

另外，您是否正确地引用了jQuery脚本?

<script src="http://code.jquery.com/jquery.min.js" type="text/javascript"></script>

Try this:

试试这个:

<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"     type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function(){
$('a').click(function(){
       alert("Evaluate Click Works");
       var match = $(mintermIndexes).compare(ArrayOfEight);
       if(match){
           alert("All squares have been checked");
       }   
       return false;
});
});
</script>
</head>
<body>
<div id="body">
       <input id="Clear" value="Clear Form" type="submit" />
       <a id="Evaluate" href="#" >Evaluate</a>

   </div>
</body>
</html>

No problem here:

#5

Try getting rid of the if(JQuery)

尝试去掉if(JQuery)

Also, make sure you are loading JQuery before you load your content scripts. If you don't, nothing will happen.

此外，请确保在加载内容脚本之前已经加载了JQuery。如果你不这样做，什么也不会发生。
