//獲取QueryString的數組
function getQueryString(){
var result = location.search.match(new RegExp("[/?/&][^/?/&]+=[^/?/&]+","g"));
for(var i = 0; i < result.length; i++){
result[i] = result[i].substring(1);
}
return result;
}
//根據QueryString參數名稱獲取值
function getQueryStringByName(name){
var result = location.search.match(new RegExp("[/?/&]" + name+ "=([^/&]+)","i"));
if(result == null || result.length < 1){
return "";
}
return result[1];
}
//根據QueryString參數索引獲取值
function getQueryStringByIndex(index){
if(index == null){
return "";
}
var queryStringList = getQueryString();
if (index >= queryStringList.length){
return "";
}
var result = queryStringList[index];
var startIndex = result.indexOf("=") + 1;
result = result.substring(startIndex);
return result;
