How to find rowindex when clicked a button in table
提问by ertan2002
I want to find row which clicked button in.
我想找到点击按钮的行。
<table>
<tr>
<td>foo 1</td>
<td><input type="button" value="Remove" id="remove1"/> </td>
</tr>
<tr>
<td>foo 2 </td>
<td><input type="button" value="Remove" id="remove2"/> </td>
</tr>
</table>
My table struct is like above. Normally I can us buttonid to get row index. But If I remove a row (tr) another row index changes. For example:
我的表结构就像上面一样。通常我可以使用 buttonid 来获取行索引。但是,如果我删除一行 (tr),另一行索引会发生变化。例如:
If I remove first row with jQuery, second row index changes as 0 then I cannot use button's id. (remove - 2 )
如果我用 jQuery 删除第一行,第二行索引更改为 0,那么我不能使用按钮的 id。(删除 - 2 )
Well I think that I must use parent function but it doesn't work.
好吧,我认为我必须使用父函数,但它不起作用。
var elem = $('#remove2');
alert(elem.parent()[0].sectionRowIndex);
I tried this one but doesn't work. I need row index that clicked button in the row.
我试过这个,但不起作用。我需要在行中单击按钮的行索引。
I hope that I explained my issue.
我希望我解释了我的问题。

You don't need ID
你不需要 ID
$('table').on('click', 'input[value="Remove"]', function(){
$(this).closest('tr').remove();
});

IF you are adding row dynamically you can
如果您要动态添加行,则可以
$(document).on('click', 'button', function () {
var indexRow = this.parentNode.parentNode.rowIndex;
document.getElementById("table-name").deleteRow(indexRow);
});
