我使用选择的 选择 ,其中我以角度方式从json文件加载数据,如果 选择 它常见的html 选择 ,但如果我决定使用所选的 选择它> ,它只是没有加载,现在我知道它在网页渲染后提取的数据。我为这个问题做了一个指示,但它不起作用。
我的HTML代码:

load_json.js:
var App = angular.module('App', []);
App.controller('appCtrl', function($scope, $http) {
$http.get('json/pueblos.json')
.then(function(res){
$scope.pueblos = res.data;
});
});
App.directive('chosen', function($timeout) {
var linker = function(scope, element, attr) {
scope.$watch('pueblos', function() {
$timeout(function() {
element.trigger('chosen:updated');
}, 0, false);
}, true);
$timeout(function() {
element.chosen();
}, 0, false);
};
return {

link: linker
};
});
关于问题的任何提示/想法?
答案 0 :(得分:2)
不确定是否存在问题,但是您正在加载jQuery两次<script src="jquery.min.js"></script>
和cdn。删除本地或仅在cdn失败时加载它。
另一点是你没有将chosen
指令添加到你的标记中,但这可能只是在问题中缺失。
以下是修改后的脚本标记的代码。同样的演示也在plunkr。
我发现您的代码没有其他问题。
// Code goes here
var App = angular.module('App', []);
App.controller('appCtrl', function($scope, $http) {
/* // commented here because can't load JSON at SO
$http.get('pueblos.json')
.then(function(res){
console.log(res);
$scope.pueblos = res.data;
});*/
$scope.pueblos = [
{
"localidad": "Germany",
"estado": "new"
},
{
"localidad": "Spain",
"estado": "old"
},
{
"localidad": "USA",
"estado": "broken"
}];
});
App.directive('chosen', function($timeout) {
var linker = function(scope, element, attr) {
scope.$watch('pueblos', function() {
$timeout(function() {
element.trigger('chosen:updated');
}, 0, false);
}, true);
$timeout(function() {
element.chosen();
}, 0, false);
/*
$(function () {
//$timeout(function() {
//console.log($(element));
$(element).chosen();
//}, 0, false);
//}),
});*/
};
return {
restrict: 'A',
link: linker
};
});
