在angularjs多个查询字符串参数 [英] Multiple query string parameters in angularjs

问题描述

我与挣扎的传球和路线读取多个查询字符串参数。

I'm struggling with passing and reading multiple query string parameters in a route.

$routeProvider.when("/joboffers:keywords:location", {
    controller: "jobOffersController",
    templateUrl: "/App/Views/JobOffer/All.html"
});

这是搜索页面：

$scope.searchJobOffer = function () {
    var vm = $scope.jobOfferSearchViewModel;
    var path = "/joboffers?keywords=" +( vm.keywords || "") + "&location=" + (vm.location || "");
    $location.path(path);
}

这是JobOffersController：

And this is the JobOffersController:

'use strict';
app.controller('jobOffersController', ['$scope', '$routeParams', 'jobOfferService', function ($scope, $routeParams, jobOfferService) {
    $scope.jobOffers = [];

    function init() {
        var keywords = $routeParams.keywords;
        var location = $routeParams.location;
    }

    init();
}]);

读$ routeParams是不工作的。如果我通过开发商作为关键字，纽约的位置，$ routeParam对象是这样的：

Reading the $routeParams is not working at all. If I pass "developer" as a keyword and "New York" as location, the $routeParam object looks like this:

{keywords: "?keywords=developer&location=New Yor", location: "k"}

有人能告诉我什么，我做错了什么？先谢谢了。

Can somebody tell me what I'm doing wrong? Thanks in advance.

P.S。
是否有可能，这是因为一个错误配置的路由呢？
当我通过 searchJobOffer 功能导航，它连接codeS的URL这样：的http：//本地主机：49380 /＃/ joboffers％ 3Fkeywords =开发商和放大器;位置=伦敦，如果我尝试使用此网址的http：//本地主机：49380 /＃/ joboffers关键字=开发商和放大器;位置=伦敦，路由系统将对我的默认路由（＃/家）

P.S. Is it possible that this is because of a wrongly configured route? When I navigate via the searchJobOffer function, it encodes the URL to this: http://localhost:49380/#/joboffers%3Fkeywords=developer&location=london and if I try to use this url http://localhost:49380/#/joboffers?keywords=developer&location=london, the routing system drops me to the default route (#/home)

推荐答案

$ routeProvider不匹配查询字符串，只有路线。此外，你设置一个完整的网​​址至$ location.path（）和$ location.path（）只需要在路径部分网址。要设置整个URL包括查询字符串，你需要使用 $ location.url（）。

$routeProvider does not match on query strings, only routes. Also, you're setting a full url to $location.path() and $location.path() only takes the path piece of the url. To set the entire URL including query string you need to use $location.url().

这里有几个选项：

$routeProvider.when("/joboffers/:location/:keywords", {
  controller: "jobOffersController",
  templateUrl: "/App/Views/JobOffer/All.html"
});

$scope.searchJobOffer = function () {
  var vm = $scope.jobOfferSearchViewModel;
  var path = "/joboffers/" + (vm.location || "") + "/" + ( vm.keywords || "");
  $location.path(path);
};

app.controller('jobOffersController', ['$scope', '$routeParams', 'jobOfferService', function ($scope, $routeParams, jobOfferService) {
  $scope.jobOffers = [];

  function init() {
    var keywords = $routeParams.keywords;
    var location = $routeParams.location;
  }

  init();
}]);

2。只有符合在工作中提供了路径和$ location.search拉PARAMS（）

（注意使用 $ location.url的（）而不是 $ location.path（））

$routeProvider.when("/joboffers", {
  controller: "jobOffersController",
  templateUrl: "/App/Views/JobOffer/All.html"
});

$scope.searchJobOffer = function () {
  var vm = $scope.jobOfferSearchViewModel;
  var url = "/joboffers?keywords=" +( vm.keywords || "") + "&location=" + (vm.location || "");
  $location.url(url);
};

app.controller('jobOffersController', ['$scope', '$location', 'jobOfferService', function ($scope, $location, jobOfferService) {
  $scope.jobOffers = [];

  function init() {
    var search = $location.search();
    var keywords = search.keywords;
    var location = search.location;
  }

  init();
}]);

3。如果你需要匹配的路线和查询字符串，尝试一些更强大的如角UI路由器

$stateProvider.state("JobOffers", {
  url: '/joboffers?keywords&location',
  controller: "jobOffersController",
  templateUrl: "/App/Views/JobOffer/All.html"
});

$scope.searchJobOffer = function () {
  var vm = $scope.jobOfferSearchViewModel;
  var url = "/joboffers?keywords=" +( vm.keywords || "") + "&location=" + (vm.location || "");
  $location.url(url);
};

app.controller('jobOffersController', ['$scope', '$stateParams', 'jobOfferService', function ($scope, $stateParams, jobOfferService) {
  $scope.jobOffers = [];

  function init() {
    var keywords = $stateParams.keywords;
    var location = $stateParams.location;
  }

  init();
}]);
