如何获取jQuery中表中任何HTML divider元素的列索引?这是我的HTML:
table {
border:1px solid navy;
width: 70%;
text-align: center;
}
table th {
text-align: center;
width:100px;
height:20px;
}
table td {
width: 100px;
height: 100px;
vertical-align: top;
text-align: right;
border: 1px solid #c6c6ec;
}
<table>
<tbody>
<tr>
<th>Header</th>
</tr>
<tr>
<th>Header1</th><th>Header2</th><th>Header3</th>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td></td>
<td>Want this column index e.g.</td>
<td></td>
</tr>
</tbody>
</table>
我设法使用以下jQuery获取行索引:
var text_var = "Want this column index e.g."
var elem = $('td').filter(function() {
var Text = $(this).contents()[0].textContent.trim();
return parseInt(Text, 10) == text_var;
});
var row_index_first = elem.parent().index();
我想用类似的东西获取专栏......?

逻辑非常相似,您只需直接检查text()
而不将其转换为整数,然后在index()
上调用elem
。试试这个:
var text_var = "Want this column index e.g."
var elem = $('td').filter(function() {
return $(this).text().trim() == text_var;
});
var row_index_first = elem.index();
console.log(row_index_first);
