Pass URL parameter to AngularJS controller?
提问by idleberg
In my app I'm reading an URL parameterwhich I'd like to pass to my Angular controller, which will then load a JSON file.
在我的应用程序中，我正在读取一个 URL 参数，我想将它传递给我的 Angular 控制器，然后它会加载一个 JSON 文件。
For example index.html?id=1234should make make the controller load data/1234.json
例如index.html?id=1234应该使控制器负载data/1234.json
My current code results in an injector error:
我当前的代码导致注入器错误：
var id = getUrlParam('id')
app.controller('myController', function ($scope, $http, id) {
$http.get("data/"+id+".json").then(function(res) {
$scope.posts = res.data
})
});
What am I doing wrong?
我究竟做错了什么？

$routeParamsis what you need.
Basicaly get your parameter like $routeParams.id
$routeParams是你所需要的。基本上让你的参数像$routeParams.id

Try this :
试试这个 ：
var getParameterByName = (function(a) {
if (a == "") return {};
var b = {};
for (var i = 0; i < a.length; ++i)
{
var p=a[i].split('=', 2);
if (p.length == 1)
b[p[0]] = "";
else
b[p[0]] = decodeURIComponent(p[1].replace(/\+/g, " "));
}
return b;
})(window.location.search.substr(1).split('&'))
var id = getParameterByName["id"];
