獲取url後的參數

//首先獲取到當前頁面的地址欄信息
var url = window.location.href;
var obj = {};
var reg = /?/;
if(url.match(reg)) {
var chars = url.split(’?’)[1];
var arr = chars.split(’&’);
for (var i = 0; i < arr.length; i++) {
var num = arr[i].indexOf("=");
if (num > 0) {
var name = arr[i].substring(0, num);
var value = arr[i].substr(num + 1);
obj[decodeURIComponent(name)] = decodeURIComponent(value);
}
}
}
console.log(obj)
