如何在Jquery中将参数传递给click事件

问题描述：

我想将以下JS更改为Jquery.但是我不知道如何在Jquery中将参数传递给click事件.谁能帮我，谢谢！

I want to change the following JS to Jquery. But I don't know how to pass parameter to click event in Jquery. Can anyone help me, thanks!

<script type="text/javascript">

function display(id){

    alert("The ID is "+id);
    }
</script>

<input id="btn" type="button" value="click" onclick="display(this.id)" />

答

更好的方法:

<script type="text/javascript">
    $('#btn').click(function() {
      var id = $(this).attr('id');
      alert(id);
    });
</script>

<input id="btn" type="button" value="click" />

但是，如果您确实需要内联单击处理程序，那么它将起作用:

But, if you REALLY need to do the click handler inline, this will work:

<script type="text/javascript">
    function display(el) {
        var id = $(el).attr('id');
        alert(id);
    }
</script>

<input id="btn" type="button" value="click" OnClick="display(this);" />
