Answer 1

All data is available under

(所有数据均可在)

window.location.search

you have to parse the string, eg.

(你必须解析字符串，例如。)

function get(name){
   if(name=(new RegExp('[?&]'+encodeURIComponent(name)+'=([^&]*)')).exec(location.search))
      return decodeURIComponent(name[1]);
}

just call the function with GET variable name as parameter, eg.

(只需使用GET变量名称作为参数调用该函数，例如。)

get('foo');

this function will return the variables value or undefined if variable has no value or doesn't exist

(如果变量没有值或不存在，此函数将返回变量值或undefined)
