Radio Button Checked not checking
提问by Satch3000
I am having a problem with the following code:
我在使用以下代码时遇到问题：
<div>
<span>Item 1</span>
<input type="radio" name="radio1" id="radio1" checked="checked" />
</div>
<div>
<span>Item 2</span>
<input type="radio" name="radio1" class="checkbox" id="radio2" />
</div>
I have added checked="checked" to the first checkbox but the one checked is the second one for some reason.
我已将 check="checked" 添加到第一个复选框，但由于某种原因，选中的复选框是第二个复选框。

Judging by the code you posted, something in the missing code must be wronge. I put your code in a jsfiddle (1) and it works like a charm.
从您发布的代码来看，丢失的代码中的某些内容一定是错误的。我把你的代码放在一个 jsfiddle ( 1) 中，它就像一个魅力。
According to w3schools, checked="checked"is correct (http://www.w3schools.com/TAGS/att_input_checked.asp). I often use <input type="radio" "name="foo" checked />, which also works.
根据 w3schools，checked="checked"是正确的 (http://www.w3schools.com/TAGS/att_input_checked.asp)。我经常使用<input type="radio" "name="foo" checked />，这也有效。

When there are multiple radio buttons with the same idand/or nameattributes, only last value is used.
当有多个具有相同id和/或name属性的单选按钮时，仅使用最后一个值。
Change the nameattribute for each radio button and it will work.
更改name每个单选按钮的属性，它将起作用。

it's because you are using the same name....id and names should be unique. Replace the name in second checkbox from radio1 to radio2
这是因为您使用相同的名称....id 和名称应该是唯一的。将第二个复选框中的名称从 radio1 替换为 radio2
