您好我有一个表单,我发送searched term
和category id
。它工作得很好,因为我发送的东西,但如果用户没有输入任何东西只有'类别ID'去,而在后端,如果searched term
为空,所有结果都显示给用户。
但是如果我在路线参数中发送一个空字符串,我会重定向到我的index
页面。这是我的app.js
代码。
when('/subcategory/:subcatId/:search', {
templateUrl: 'partials/subcategory.html',
controller: 'SubCategoriesController'
}).
我的表格
<form name="searchCategoryForm">
<div class="col-md-9 col-xs-10 col-sm-10">
<input class="form-control" placeholder="Find your item here...." ng-model="search" type="text" style="color:#09669c;">
</div>
<div class="col-md-2 col-xs-2 col-sm-2">
<a class="btn btn-primary" role="button" href='#/subcategory/{{cats[clicked_category].id}}/{{search}}'> Search</a>
</div>
</form>
我的controller.js
$scope.search_term = $routeParams.search;
$scope.category_id = $routeParams.subcatId;
/* Search category form */
$scope.search_category = function () {
$http({
method: 'GET',
url: 'abc',
params: {"name": $scope.search_term, "category_id": $scope.category_id},
headers: {'Content-Type': 'application/x-www-form-urlencoded', 'Authorization': $rootScope.keyword_auth_token}
})
.success(function (data) {
$scope.search_category_result = data.items;
console.log($scope.search_category_result);
})
.error(function (data) {
console.log(data);
});
};
/* Search category form ends here*/
if ($scope.search_term && $scope.category_id)
{
$scope.search_category();
}

我相信您应该将搜索字词标记为可选,并在后面加上问号(?):
when('/subcategory/:subcatId/:search?', {
templateUrl: 'partials/subcategory.html',
controller: 'SubCategoriesController'
}).
