如何修改easyui的combotree的下拉框的宽度 在ie上宽度几乎为0

：看了一下不知道楼主的具体问题是什么。 下面是我自己下项目中做的。 html页面，里面绑定了一个选择节点的函数 js代码： $('#cc').combotree('loadData', ${treeData})其中${treeData}是一个JSON字符串，从后台传过来的。

<script type="text/javascript">

<!--

//图片滚动函数

function picScroll(pic,direction,n)

{

var getArr = new Array()

var move

var length

if(n==undefined){

n=1

}else{

n = 2*n-1

}

switch(direction)

{

case 'top':

{

if(pic[0].offsetHeight<=(1/n)*pic[0].scrollTop)

{

pic[0].scrollTop -=n*pic[0].offsetHeight

}else{

pic[0].scrollTop +=1

}

break

}

case 'left':

{

if(pic[0].offsetWidth<=(1/n)*pic[0].scrollLeft)

{

pic[0].scrollLeft -=n*pic[0].offsetWidth

}else{

pic[0].scrollLeft +=1

}

break

}

case 'right':

{

break

}

case 'bottom':

{

break

}

default:

{//默认是left

if(pic[0].offsetWidth<=pic[0].scrollLeft)

{

pic[0].scrollLeft -=pic[0].offsetWidth

}else{

pic[0].scrollLeft +=1

}

break

}

}

}
