双击javascript启用输入 [英] javascript enable input on double click

问题描述

我有一些禁用某些输入的表单。我希望这些输入在双击时启用。不幸的是，JS事件似乎不会禁用已禁用的输入。

 < input type =textvalue =asdf已禁用=disabledondblclick =this.disabled = false;> 
  

有没有办法在这个限制之下？

或者我只是需要在一个范围内包装任何受影响的输入以容纳该事件？

c> ondblclick 不会在禁用元素上触发，您应该标记它 readonly ：

 < input type =textvalue = asdfreadonly =trueondblclick =this.readOnly ='';>

I have a form with some inputs disabled. I want these inputs to be enabled when double clicked. Unfortunately, JS events seem not to fire on disabled inputs.

<input type="text" value="asdf" disabled="disabled" ondblclick="this.disabled=false;">​

Is there a way around this limitation?

Or am I just going to have to wrap any affected input in a span to house the event?

解决方案

ondblclick does not get fired on a disabled element, you should mark it as readonly:

<input type="text" value="asdf" readonly="true" ondblclick="this.readOnly='';">
