表单验证检查选项，并选择检查不正常

Question

我有这个脚本一个问题，我需要的表单验证底部的程序性，首先检查与选择无线电设备是否有针对性的，然后，然后才要求从特定的无线电下拉时间开始。这似乎是完整的，如果我能得到：

if (document.getElementById('first').checked) { 
    frmvalidator.addValidation("selects", "dontselect=000", "select a time"); 
} 

声明工作JavaScript，但它只是寻找的时候，它的真实的，但我似乎失去了一些东西。请协助

Answer 1

在我看来，你真正想要的是ID为“第一”的是，当检查单选按钮的监听器，启用或禁用基于按钮是否被选中或毗邻选择元素不。你可以做到这一点：

<input type="radio" ... onclick="this.form.selects.disabled = !this.checked;"> 

您应该禁用选择元素时脚本页面加载，而不是在HTML。

在选择元素，您应该设置第一个选项，在HTML选择：

<option value="000" selected>Select a Date</option> 

Answer 2

这似乎需要在ID前面的空格=“选择”

Answer 3

您的输入无线电必须有一个“ID”不只是一个名字。它适用于我..

Answer 4

更改代码

<input type="radio" name="radios" value="radio1" /> 

要

<input type="radio" name="radios" value="radio1" id="radios" /> 

也许这可以帮助..
