复制代码 代码如下:
function getparam(paramname) {
    paramvalue = ;
    isfound = false;
    if (this.location.search.indexof(?) == 0 && this.location.search.indexof(=) > 1) {
        arrsource = unescape(this.location.search).substring(1, this.location.search.length).split(&);
        i = 0;
        while (i             if (arrsource[i].indexof(=) > 0) {
                if (arrsource[i].split(=)[0].tolowercase() == paramname.tolowercase()) {
                    paramvalue = arrsource[i].split(=)[1];
                    isfound = true;
                }
            }
            i++;
        }
    }
    return paramvalue;
}
