Making a table row (tr) clickable with jQuery (wit

问题:

Just a (hopefully) quick question, I have the following HTML code:

<tr>
 <td><img src="img/icons/file_pdf.png"></td>
 <td><a href="../upload/1267473577.pdf">Bulletin 1st March 2010</a></td>
 <td>(01/03/10)</td>
</tr>

Ideally I'd like a way to grab the a href link using jQuery and make it so that no matter where you click on that particular table row, it will take you to that link.

Is there any way to do this? I can do it via icky inline JavaScript as an absolute last resort, but since finding out about jQuery I quite like the idea of being able to do this cleanly and unobtrusively :-)

回答1:

Assuming it's a "normal" link (not a Javascript trigger) this will be sufficient:

$("tr").click(function() {
  window.location.href = $(this).find("a").attr("href");
});

You will probably want to communicate this behaviour to the user in some way. The minimal approach would be changing the cursor while hovering over the row.

I found this solution to work well for me.

$('table tr').live("click",function(e){ 
    if (e.target instanceof HTMLInputElement || e.target instanceof HTMLAnchorElement){
        return;
        }
        alert('works');
});

If you have another link inside the table, like a delete link, you may want to use the event object to check if the user clicked over that particular link and avoid the redirection.

Example HTML:

<tr title="http://path/to/download">
  <td><img src="img/icons/file_pdf.png"></td>
  <td><a href="/path/to/delete">Delete</a></td>
  <td>(01/03/10)</td>
</tr>

Example JavaScript:

$("tr").click(function(event) {
  if(event.target.nodeName != "A"){
    window.location.href = $(this).attr("title");
  }
});

Usually my tables have an action cell with edit and delete, so I use the row click event to redirect to the show action.
