【问题描述】:
在这个jsfiddle中
http://jsfiddle.net/littlesandra88/eGRRb/
我是否提交了自动生成的按钮。每个表格行都有一个唯一的 ID 号,如果需要,每个提交按钮也可以获得相同的唯一编号。
问题
问题是有多个提交按钮,我怎么知道哪个被按下了?
HTML
<form action="" method="post">
<table class="alerts tablesorter" id="accTable" cellspacing="0">
<thead>
<tr class="header">
<th class="activity-header"> A </th>
<th class="activity-header"> Signed </th>
<th class="activity-header"> </th>
</tr>
</thead>
<tbody>
<tr class="row" id="7249">
<td class="activity-data">7249</td>
<!-- tablesorter can't sort a column with check boxes out-of-the-box, so it needs something to sort on. That is why the span tag is here -->
<!-- a jquery script is watching the state of the checkbox, so when clicked the value in the span is updated -->
<td class="checkbox"> <span style="display:none;">0</span> <input name="signed" type="checkbox" > </td>
<td class="edit-column"> <input value="Save" type="submit" name="7249"></td>
</tr>
<tr class="row" id="61484">
<td class="activity-data">61484</td>
<td class="checkbox"> <span style="display:none;">1</span> <input name="signed" type="checkbox" checked > </td>
<td class="edit-column"> <input value="Save" type="submit" name="61484"></td>
</tr>
</tbody>
</table>
</form>
JavaScript
$(document).ready(function() {
$("#accTable").tablesorter();
// :checkbox stops from executing the event on the save button. Same as input[type=checkbox]
$('#accTable input:checkbox').click(function() {
// insert 1 or 0 depending of checkbox state in the tag before the input tag. In this case <span> is before <input>
// this is done so tablesorter have something to sort on, as it doesn't support checkbox sort out of the box.
var order = this.checked ? '1' : '0';
$(this).prev().html(order);
$(this).parents("table").trigger("update");
});
});
// sends the form content to server side, and stay on page
$('form').live('submit', function() {
alert('test');
// don't redirect
return false;
});
