jQuery onClick 阻止默认

jQuery onClick preventDefault

提问by ShadowFlame

I have a table of which I want to suppress the link clicks, because I need the links for other functionality.

我有一个表格，我想抑制链接点击，因为我需要其他功能的链接。

The structure of the table is something like this:

表的结构是这样的：

<table>
<tr><th>Day</th><th>Event</th>
<tr class="DAY" id="DAY_0"><td>1-8-2013</td><td><a href="?tab=tabCalendar&dayEvent=DAY_0">Add Event</a></td></tr>
<tr class="DAY" id="DAY_1"><td>2-8-2013</td><td><a href="?tab=tabCalendar&dayEvent=DAY_1">Add Event</a></td></tr>
</table

my jquery code to try and block the from refreshing the page, and showing the id is this

我的 jquery 代码尝试阻止刷新页面，并显示 id 是这样的

<script>
  $("a").click(
      function(event) {
        event.preventDefault();
        alert('Picked: '+ event.target.id.slice(4) );
      }
    );
  </script>

I have also tried the following

我也试过以下

$(".DAY").click(function(){//to catch the class DAY.click()

and even

乃至

$("[id^=DAY]").click(function(){//to catch the id DAY*.click

however, none of these function did anything.

然而，这些功能都没有做任何事情。

Simplest approach:

最简单的方法：

<script>
   $(".DAY").click(
      function(event) {
         event.preventDefault();
         alert('Picked: '+ $(this).attr('id').slice(4));
      }
   );
</script>

Try to put the script in DOM READY

尝试将脚本放入 DOM READY

<script type="text/javascript">
    $(document).ready(function(){
        $("a").on('click',function(event) {
            event.preventDefault();
            alert('Picked: '+ $(this).parent('td').parent('tr').id.slice(4) );
        });
     });
</script>

Try this:

尝试这个：

$(document).ready(function(){

    $("a").click(
      function(event) {
        event.preventDefault();

          DATA = $(this).closest('tr').attr('id').slice(4);

        alert('Picked: ' + DATA);
      }
    );

});

This will get select the IDof the ayou clicked. I've also created this as a jSFiddle: http://jsfiddle.net/pAZeb/

这将让选择ID的a，你点击。我也将它创建为 jSFiddle：http: //jsfiddle.net/pAZeb/

You need to find the idof the closesttrof the clicked a

你需要找到id的最接近tr的点击的a

Try

尝试

jQuery(function($){
    $("a").click(function(event) {
        event.preventDefault();
        alert('Picked: '+ $(this).closest('tr').attr('id').slice(4) );
    });
});

});
