例子,jquery获取表格之间的总行数。
<table>
<tr id="parent_1">
<td>Parent 1</td>
</tr>
<tr class="child">
<td>Child 1</td>
</tr>
<tr class="child">
<td>Child 2</td>
</tr>
...
<tr id="parent_2">
<td>Parent2</td>
</tr>
...
</table>
记得在此处引入jquery类库文件。
<script>
var childCount = ($('#parent_2').get(0).rowIndex - $('#parent_1').get(0).rowIndex) - 1;
$('#parent_1 ~ .child:not(#parent_2 ~ *)').size();
var rowid1 = 'parent_1';
var rowid2 = 'parent_2';
var rows = $("#"+rowid1).parent().find('tr');
var count = 0;
for (var i = 0; i < rows.size(); i++) {
var el = rows.get(i);
// Done counting
if (el.id == rowid2) break;
if (el.id != rowid1) {
++count;
}
}
alert("There are " + count + " rows between");
</script>
