jQuery Validate plugin: input vs. textarea
提问by tim peterson
I'm wondering why there is a difference in jQuery Validate plugin's default handling of <input>vs. <textarea>. In the demo below, notice that the requiredclass makes the <input>required but not the <textarea>.
我想知道为什么 jQuery Validate 插件的默认处理<input>与<textarea>. 在下面的演示中，请注意required该类生成了<input>required 而不是<textarea>.
<form>
<input class='required' />
<textarea class='required' ></textarea>
<button value='submit'>submit</button>
</form>
$('form').validate();

It has absolutely nothing to do with inputvs.textarea.
它与inputvs.完全无关textarea。

It's failing because each inputmusthave a unique nameattribute in order for this plugin to work properly. See the "Markup Recommendations" section of the "General Guidelines". Otherwise, only the very first element is validated and all others are ignored.
它失败了，因为每个插件都input必须有一个唯一的name属性才能使这个插件正常工作。 请参阅“通用指南”的“标记建议”部分。否则，仅验证第一个元素，忽略所有其他元素。
<form>
<input name="thename" class='required' />
<textarea name="another" class='required'></textarea>
<button value='submit'>submit</button>
</form>
