angularjs中的多个查询字符串参数

Question

我正在努力在路由中传递和读取多个查询字符串参数.

$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:

'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();
}]);

阅读$ routeParams根本不起作用.如果我将"developer"作为关键字并将"New York"作为位置传递,则$ routeParam对象如下所示:

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

谁能告诉我我做错了什么？提前致谢.

PS这可能是因为错误配置的路由吗？当我通过该searchJobOffer函数导航时,它将URL编码为:http://localhost:49380/#/joboffers%3Fkeywords=developer&location=london如果我尝试使用此URL http://localhost:49380/#/joboffers?keywords=developer&location=london,路由系统会将我置于默认路由(#/ home)

Answer 1

$ routeProvider与查询字符串不匹配,只与路由匹配.此外,您正在设置一个完整url的$ location.path()和$ location.path()只接受path网址的一部分.要设置包含查询字符串的整个URL,您需要使用$location.url().

以下是一些选项:

1.改用漂亮的URL

$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.仅匹配作业提供路径并从$ location.search()中提取参数

(注意使用$location.url()而不是$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.如果您需要匹配路由和查询字符串,请尝试像angular-ui-router更健壮的东西

$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();
}]);
