问题描述
我有一个名为选择的单选按钮,选项是yes和no。如果我选择任何一个选项并单击标记为清除的按钮,则需要使用javascript清除选定的选项。如何才能做到这一点?
解决方案
您不需要具有唯一的 id
为元素,您可以通过它们的 name
属性访问它们:
如果您使用 name =选择
,然后:
-
很简单:
$('input [name = Choose]')。attr('checked',false);
-
或在纯JavaScript中:
var ele = document.getElementsByName(Choose);
for(var i = 0; i< ele.length; i ++)
ele [i] .checked = false;
I have a radio button named "Choose" with the options yes and no. If I select any one of the options and click the button labeled "clear", I need to clear the selected option, using javascript. How can I accomplish that?
解决方案
You don't need to have unique id
for the elements, you can access them by their name
attribute:
If you're using name="Choose"
, then:
With jQuery it is as simple as:
$('input[name=Choose]').attr('checked',false);
or in pure JavaScript:
var ele = document.getElementsByName("Choose"); for(var i=0;i<ele.length;i++) ele[i].checked = false;
