IE中通过setCapture监听鼠标按下和移动，Chrome浏览器中没有相应的方法，所以通过其它方式来实现。

兼容IE和Chrome的拖动改变布局宽度

var leftWidth;

var widths=[140,0];

var iw=1;

var swidth;

var sheight;

function get(id) {

return document.getElementById(id)

}

function SwitchLeftWidth(){

document.all("left").style.width=widths[iw];

iw++;

if(iw>=widths.length) iw=0;

}

function startResize(){

if(resizeBox.setCapture){

resizeBox.setCapture();

resizeBox.οnmοusemοve=function(e){

var w=(e||event).x-6;

if(w<0) w=0;

document.all("left").style.width=w;

}

resizeBox.οnmοuseup=function(){

resizeBox.releaseCapture();

leftWidth=document.all("left").style.pixelWidth;

resizeBox.οnmοusemοve=null;

resizeBox.οnmοuseup=null;

}

}else{

var oLeft = get("left"),oMain =get("main"),

oMainTd =get("mainTd");

var oWrapperDiv=ge("wrapperDiv");

swidth = document.body.clientWidth;

oWrapperDiv.style.display="";
