label标签的用法

label 标签for属性

<h1>显式指定通过for(for的值就是对应radio的id的值)</h1>
<form>
<label for="male">Male</label>
<input type="radio" name="sex" id="male" />
<br />
<label for="female">Female</label>
<input type="radio" name="sex" id="female" />
</form>
<h1>隐式指定只用label标签把radio包括进来</h1>
<form>
<label>Male<input type="radio" name="sex" id="male" /></label>
<br />
<label>Female<input type="radio" name="sex" id="female" /></label>
</form>
