JavaScript - OffFocus事件？ [英] JavaScript - OffFocus event?

问题描述

我想要做的是显示一个文本颜色为黑色的输入字段。

然后当人点击输入栏（onfocus）我想改变文字颜色为 red 。

然后，当那个人在输入框外面点击（不再焦点），我想把文本颜色改回黑色。

我知道如何使用以下方法处理JavaScript onfocus事件：

 < input ctype =textonfocus = this.style.color = '红色'; /> 
  

但是，如何处理关闭焦点以将文字颜色改回黑色

预先感谢 尝试使用 onblur ，当元素失去焦点时调用它。

What I want to do is display an input field with the text color black.

Then when the person clicks inside the input field (onfocus) I want to change the text color to red.

Then, when the person click outside of the input fied (no longer focus), I want to change the text color back to black.

I know how to handle the JavaScript onfocus Event using the following:

<input ctype="text" onfocus="this.style.color='red';" />

But how do I handle the "off focus" to change the text color back to black?

Thanks in advance

解决方案

try using onblur, it is called when an element loses focus.
