Javascript删除表格tbody标签 [英] Javascript delete a table tbody tag
问题描述
我知道我可以使用下面的代码在vanilla Javascript中删除行:
var table = document.getElementById('table') ;函数deleteRow(){table.deleteRow(1);};
table {background:#ccc;宽度:100%; } table thead {background:#333;颜色:#fff; } table tbody {background:magenta;颜色:#fff; }
< button onclick =deleteRow()> ;删除行< / button>< table id =table> < THEAD> < TR> < TD> FOO< / TD> < TD>巴≤; / TD> < / TR> < / THEAD> < TBODY> < TR> < TD> LOREM< / TD> < TD> ipsum的< / TD> < / TR> < / tbody的> < TBODY> < TR> < TD> LOREM< / TD> < TD> ipsum的< / TD> < / TR> < / tbody的> < / table>
但是这段代码留下了一个空的tbody标签behing。 JS有删除thead和tfoot元素的方法,但它似乎缺少一个 deleteTbody
一个。
我应该如何使用纯javascript来移除 tbody
及其所有内容?没有jQuery的,请!!
如果你想删除 tbody
标签,您可以选择行本身而不是表格,然后使用 removeChild
函数。
var table = document.getElementById('table');
var row = document.getElementsByTagName('tbody')[0];
函数deleteRow(){
row.parentNode.removeChild(row);
};
I know I can use the following code to remove rows in vanilla Javascript:
var table = document.getElementById('table');
function deleteRow () {
table.deleteRow(1);
};
table { background: #ccc; width: 100%; }
table thead { background: #333; color: #fff; }
table tbody { background: magenta; color: #fff; }
<button onclick="deleteRow()">Delete Row</button>
<table id="table">
<thead>
<tr>
<td>foo</td>
<td>bar</td>
</tr>
</thead>
<tbody>
<tr>
<td>lorem</td>
<td>ipsum</td>
</tr>
</tbody>
<tbody>
<tr>
<td>lorem</td>
<td>ipsum</td>
</tr>
</tbody>
</table>
But this code leaves an empty tbody tag behing. JS has methods for removing thead and tfoot elements, but it seems it's missing a deleteTbody
one.
How am I supposed to remove a tbody
and all it's contents by using pure javascript only? No jQuery, please!
If you want to remove the tbody
tag, you could select the row itself rather than the table, then use the removeChild
function.
var table = document.getElementById('table');
var row = document.getElementsByTagName('tbody')[0];
function deleteRow () {
row.parentNode.removeChild(row);
};
