獲取單個引數值

function getParam(key){
    //假設位址列url為http://www.xxx.com/test?name=zhangshan&age=50#hello;
 

    var url = window.location.href; 
    var pattern = new RegExp('[?&]*'+ key +'=([^&]+)');
    try {
        var value = url.match(pattern)[1];
        return value;
    } catch (err) {
        return undefined;
    }
}
