Hi Mauli，



以下功能用于从URL读取查询字符串并将值映射到ddl选项



这可以在document.ready（）函数中使用，如

Hi Mauli,

Below function is used to read the query string from URL and map the value to ddl option

This can be used in document.ready() function like

（ document .ready（函数（）{
var qs =（ function （a）{
if （a == ） return {};
var b = {};
< span class =code-keyword> for （ var i = 0 ;我<则为a.length; ++ i）
{
var p = a [i] .split（' ='）;
if （p.length！= 2 ）继续;
b [p [ 0 ]] = decodeURIComponent（p [ 1 ]。replace（/ \\ \\ + / g， ））;
}
返回 b;
}）（ window 。 location .search.substr（ 1 ）。split（' &'））;

if （qs [' test']！= undefined ）{

(document.ready(function() { var qs = (function(a) { if (a == "") return {}; var b = {}; for (var i = 0; i < a.length; ++i) { var p=a[i].split('='); if (p.length != 2) continue; b[p[0]] = decodeURIComponent(p[1].replace(/\+/g, " ")); } return b; })(window.location.search.substr(1).split('&')); if(qs['test'] != undefined){

（' ＃ddlCountry'）。val（qs [' 测试]）;
}
}））;

('#ddlCountry').val(qs['test']); } }));

希望这会对你有所帮助。
