jQuery对url的操作

// 修改URL中指定参数的值
function changeURLArg(url,arg,arg_val){
    var pattern=arg+'=([^&]*)';
    var replaceText=arg+'='+arg_val;
    if(url.match(pattern)){
        var tmp='/('+ arg+'=)([^&]*)/gi';
        tmp=url.replace(eval(tmp),replaceText);
        return tmp;
    }else{
        if(url.match('[?]')){
            return url+'&'+replaceText;
        }else{
            return url+'?'+replaceText;
        }
    }
    return url+'
'+arg+'
'+arg_val;
}

// 删除url中某个参数
function funcUrlDel(name){
    var loca = window.location;
    var baseUrl = loca.origin + loca.pathname + "?";
    var query = loca.search.substr(1);
    if (query.indexOf(name)>-1) {
        var obj = {}
        var arr = query.split("&");
        for (var i = 0; i < arr.length; i++) {
            arr[i] = arr[i].split("=");
            obj[arr[i][0]] = arr[i][1];
        };
        delete obj[name];
        var url = baseUrl + JSON.stringify(obj).replace(/["{}]/g,"").replace(/:/g,"=").replace(/\,/g,"&");
        return url
    };
}
