jquery获取指定url的所有参数和重构url

js:

/**
 * 获取请求url中的全部参数的object对象
 * @returns
 */
function getAllUrlParms(url)    {
	 var theRequest = new Object();
     if (!url)
         url = location.href;
     if (url.indexOf("?") !== -1)
     {
         var str = url.substr(url.indexOf("?") + 1) + "&";
         var strs = str.split("&");
         for (var i = 0; i < strs.length - 1; i++)
         {
             var key = strs[i].substring(0, strs[i].indexOf("="));
             var val = strs[i].substring(strs[i].indexOf("=") + 1);
             theRequest[key] = val;
         }
     }
     return theRequest;
}

根据参数判断url是否相同,并重构新的url:

function checkUrlFun(oldUrl,paramObj,newUrl){
	var returnUrl = "";
	var updateFlag = false;
	if(!oldUrl || oldUrl == 'about:white'){
		//页面尚未加载过,利用newUrl拼接paramObj,而且返回
		updateFlag = true;
	}else{
		//页面已经加载过
		var obj = getAllUrlParms(oldUrl);
		if(paramObj && JSON.stringify(paramObj) != '{}'){
			for(var key in paramObj){
				//若是老的url里面和paramObj里面有参数不一样,那么须要构建新的url
				if(!obj[key] || obj[key] != paramObj[key]){
					updateFlag = true;
					break;
				}
			}
		}
	}
	if(updateFlag){
		var index = newUrl.indexOf("?");
		if(index != -1){
			newUrl = newUrl.substring(0,index);
		}
		var appendUrl = $.param(paramObj);
		newUrl += "?"+appendUrl;
		returnUrl = newUrl;
	}
	return returnUrl ;
}

根据paramObj设置页面的全局变量的值:

/**
 * 修改页面默认变量的值
 * @returns
 */
function changeVariableValueFun(paramObj){
	if(paramObj && JSON.stringify(paramObj) != '{}'){
		for(var key in paramObj){
			var val = key.replace("object.","");
			window[val] = paramObj[key];
			$('#'+val).val(paramObj[key]);
		}
	}
}
