js替换字符串中img标签src路径

var replacestr = pagestr.replace(/<img [^>]*src=['"]([^'"]+)[^>]*>/gi,function(match,capture){
    //返回整个标签
    match = match.replace('/static/web',path.join(__static,'/web'));
    return match;
    //capture,返回每个匹配的字符串
    // capture = capture.replace('/static/web',path.join(__static,'/web'));
    return capture;
});

• 说明：这里path.join()是调用了nodejs中的path
