本文介绍了如何放大按钮，因为它获得焦点？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
< html>< p>
< form name =myForm>
< button onfocus =width = 200; height = 200> myButton< / button>
<按钮> myOtherButton< / button>
< / form>
< / html>
任何想法如何使它工作？
解决方案
< form name =myForm>
< button onfocus =this.style.width ='200px'; this.style.height ='200px';> myButton< / button>
<按钮> myOtherButton< / button>
< / form>
我想在实现这个之后，您还需要在焦点离开后恢复大小。
< button onfocus =this.style.width ='200px'; this.style.height ='200px'; onblur =this.style.width = this.style.height ='';> myButton< / button>
如果您所做的不仅仅是这些，我会建议将这些代码分解为多个函数并使其更好JavaScript设计决策。
I'm trying to make my button bigger when it receives focus:
<html>
<form name="myForm">
<button onfocus="width=200; height=200">myButton</button>
<button>myOtherButton</button>
</form>
</html>
Any idea how can I make it work?
解决方案
<form name="myForm">
<button onfocus="this.style.width = '200px'; this.style.height = '200px';">myButton</button>
<button>myOtherButton</button>
</form>
I imagine after implementing this, you will also want to restore the size after the focus leaves.
<button onfocus="this.style.width = '200px'; this.style.height = '200px';" onblur="this.style.width = this.style.height = '';">myButton</button>
If you're doing much more than that, I would recommend separating this code into functions and making better JavaScript design decisions.
