```JavaScript
|
||
|
|
window.getQueryParam = (function(a) {
|
||
|
|
if (a == "") return {};
|
||
|
|
var b = {};
|
||
|
|
for (var i = 0; i < a.length; ++i)
|
||
|
|
{
|
||
|
|
var p=a[i].split('=', 2);
|
||
|
|
if (p.length == 1)
|
||
|
|
b[p[0]] = "";
|
||
|
|
else
|
||
|
|
b[p[0]] = decodeURIComponent(p[1].replace(/\\+/g, " "));
|
||
|
|
}
|
||
|
|
return b;
|
||
|
|
})(window.location.search.substr(1).split('&'));
|
||
|
|
```
|
||
|
|
|
||
|
|
**Пример:** `?topic=123&name=query+string`
|
||
|
|
|
||
|
|
**Использование:**
|
||
|
|
|
||
|
|
```JavaScript
|
||
|
|
var qs = window.getQueryParam;
|
||
|
|
qs["topic"]; // 123
|
||
|
|
qs["name"]; // query string
|
||
|
|
qs["nothere"]; // undefined (object)
|
||
|
|
```
