如何获取URL地址栏参数？

如：https://gist.github.com/send.php?name=jikey&age=30&lan=js;
getParam(); -> { name : jikey, age : 30, lan : js}
getParam('name') -> jikey


PS:
1. 回复时注意加上下面这句话，才会有语法高亮或格式缩进。
```javascript
// you code
```
2. 粘贴代码时请使用shift+tab，缩进前面的空白。

//接收传参字符
var parameter=window.location.search
//And then……

var __location='https://gist.github.com/send.php?name=谭技安%&age=30&lan=125';

        mainStr=mainStr.substr(0,mainStr.length-1)+'}';
        mainStr=(new Function("return"+mainStr))();
        var key=key||'';
        if(key){
            return mainStr[key];

        args[match[1]] = match[2];
    }
    return key ? args[key] : args;
