获取url中的参数值

.filter('queryString', [
function () {
var parseLocation = function () {
var pairs = window.location.search.substring(1).split("&");
var obj = {};
var pair;
var i;

for (i in pairs) {
if (pairs[i] === "") continue;

pair = pairs[i].split("=");
obj[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1]);
}

return obj;
};

return function (key) {
return parseLocation()[key];
}
}
])
