应该如何写正则表达式来提取“url(”与“)”中的图片地址？？？======== 满意答案 ========var str="NavBar{width:888px; height:35px; float:left;padding-left:62px; margin-top:1px; background:url(images/menu_bj.jpg) repeat-x; line-height:35px; font-size:12px;}.me{width:100px; height:35px; float:left; color:#FFFFFF; font-weight:bold; background:url(images/menu_homebj.jpg) repeat-x;}"
var arr = str.match(/url\(.+?\)/ig);
for(var i =0; i<arr.length; i++){document.write(arr[i].replace("url(","").replace(")","") + "<br />");
}var str="NavBar{width:888px; height:35px; float:left;padding-left:62px; margin-top:1px; background:url(images/menu_bj.jpg)"+

" background:url(images/menu_homebj.jpg) repeat-x;}";
var reg=/(?=url\()[^)]+(?=\))/g;
var r=str.match(reg),
result=[];for(var i=0;i<r.length;i++){
result.push(r[i].toString().slice(4,r[i].length));}alert(result);-----var str="NavBar{width:888px; height:35px; float:left;padding-left:62px; margin-top:1px; background:url(images/menu_bj.jpg) repeat-x; line-height:35px; font-size:12px;}.me{width:100px; height:35px; float:left; color:#FFFFFF; font-weight:bold; background:url(images/menu_homebj.jpg) repeat-x;}";
