经过一番思考,我有了一个解决方案。
这里的一些“魔法”是在 $scope 中有一个对象(名为 $scope.filter)来保存所有表单输入值,因此它很容易使用,并且不需要对其进行任何修改如果向表单中添加了新的输入,则在控制器中加入。
angular.module('myApp')
.controller('myController', ['$scope', '$http' '$location', function($scope, $http, $location) {
$scope.filter = {};
$scope.init = function(){
// $location.search() will return an object with the params,
// those values are set to $scope.filter, and the filter values are initialized in case of direct link to the page
$scope.filter = $location.search();
$scope.executeFilter();
};
// doing the job of fetching the data I want to present,
// using the filter values as a Json in that server call
$scope.executeFilter = function(){
// making sure to update the url with the current filter values,
// so the user is able to copy the relevant url for a later use
$location.search($scope.filter);
var paramsAsJson = angular.toJson($location.search());
$http.post('my-url', paramsAsJson).success(function(data) {
// update view
});
};
$scope.init();
}]);
这是一个示例视图:
<form ng-submit="executeFilter()">
<input name="some_text" type="text" ng-model="filter.some_text">
<!-- more inputs here -->
// it will work even with multiple select
// (will pass to the server a json with array of selected values)
<select multiple="multiple" name="some_options" ng-model="filter.some_options">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
</select>
<button>Filter</button>
</form>
因此,现在如果用户尝试使用像 www.my-url.com/?some_text=foo 这样的 url 打开此页面,则带有指令 ng-model="filter.some_text" 的输入将在页面加载后包含“foo”,并且将发出带有该参数的服务器请求。
