的无线电组的值.这个电台组的 html 代码是.
I am trying to get value of radio group with name managerelradio
. My html code for this radio group is.
<label><input type="radio" name="managerelradio" value="Yes" id="Add">Add</label>
<label><input type="radio" name="managerelradio" value="No" id="Remove">Remove</label>
Jquery 是这样的..
and Jquery for this is..
var manageradiorel = $('input[name = "managerelradio"]:checked' , '#managechildform').val();
alert(manageradiorel);
它显示我未定义.
虽然我也试过了.
var manageradiorel = $('input[name = "managerelradio"]:checked').val();
alert(manageradiorel);
但我仍然得到未定义的值.
But still I am getting undefined value.
试试这个
var manageradiorel = $("input:radio[name ='managerelradio']:checked").val();
alert(manageradiorel);
请检查这个 DEMO ..它会正常工作
Plese check this DEMO ..it will work fine
注意:必须选择您的单选按钮之一.否则会返回 undefined
Note: One of your radio button must be selected. Otherwise it will return undefined
您可以使用 checked
属性将单选按钮设为默认选择
You can use checked
attribute to make a radio button selected as default
