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+'\n'+arg+'\n'+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();
     if (query.indexOf(name)>-) {
         var obj = {}
         var arr = query.split("&");
         for (var i = ; i < arr.length; i++) {
             arr[i] = arr[i].split("=");
             obj[arr[i][]] = arr[i][];
         };
         delete obj[name];
         var url = baseUrl + JSON.stringify(obj).replace(/[\"\{\}]/g,"").replace(/\:/g,"=").replace(/\,/g,"&");
         return url
     };
 }
