单选按钮列表 [英] RadioButtonList

问题描述

嗨


我有一个评估页面

最后我要提交此评估


但在此之前我想检查页面中的每个RadioButtonList是否都被检查


我该怎么做


我应该做什么（IF声明）

但是我有20个问题

所以......我会为他们所有人做的!!!!

或者还有另外一种方法检查一下??

解决方案

你可以尝试这个代码

展开 | 选择 | Wrap | 行号

比你多了


i了解这个想法


但我怎么写这个变量


var grp = document.forms [0] .elements [" BtnList1"];



这不是可用

document.forms [0] .elements [" BtnList1"];


它给我一个错误

< blockquote>表单中单选按钮的名称是什么？


你需要使它与javascript中引用的名称相同： -

What is the name given to your radio buttons in the form?

You need to make it the same name as referred to in the javascript :-
