单选按钮值未解析
Posted
技术标签:
【中文标题】单选按钮值未解析【英文标题】：Radio button Values not Parsed 【发布时间】：2012-02-01 05:01:50 【问题描述】：我正在构建一个基于输入值计算点的点计算系统。 我在这个单选按钮上使用了一些 jquery ui 样式，现在它总共没有加起来。 代码太长，无法在此处发布，因此请查看live preview。我读了很多次代码，找不到任何东西。
编辑：这是我的代码的精简版： 问题在于 div part2 中的单选按钮，请阅读我的 cmets。

【问题讨论】：
在此处发布您的帖子，以便任何人都可以帮助您。 我注意到的第一件事是一些 js 错误：c is not defined 和 show3 is not defined。另外，它应该如何工作？究竟是什么不工作？我们需要更多信息。
c 在 if..else 语句中定义，但 show 3 稍后定义
【参考方案1】：
我不认为它与 jquery ui 相关联，而是与线路相关联
var tcfc2 = parseInt(document.getElementById('form').TCFC2.value, 10) || 0;
由于您有 2 个带有单选按钮的元素，称为 TCFC2，因此会使用它们创建一个数组。此外，第一个无线电的值始终为 1，第二个无线电的值始终为 2。您需要检查“已检查”属性，而不是确定人们是否说法语的值。
var tcfc2 = document.getElementById('form').TCFC2[0].checked -0 ;
没有parseInt，返回“true”或“false”，“-0”是强制int转换。
最后，我会将收音机或输入类型文本重命名为 TCFC2 以外的名称。 （并合并您的 css，将脚本和样式从 html 文件中取出并放入它们自己的文件中以进行维护，并将您的 var 命名为比 a、b 和 c 更有意义的名称……）
【讨论】：
如果我想给是2分，不给1分，然后加到总分中怎么办？var tcfc2 = document.getElementById('form').TCFC2[0].checked -0 +1; 或 var tcfc2 = document.getElementById('form').TCFC2[0].checked ? 2 : 1;
代码略少，将getElementById替换为getElementsByName：document.getElementsByName('TCFC2')[0].checked以上是关于单选按钮值未解析的主要内容，如果未能解决你的问题，请参考以下文章
