我有类似的数组的集合:
$scope.table = {
hstep: [1, 2, 3],
mstep: [1, 5, 10, 15, 25, 30]
};
我想列出这两个字段HSTEP和MSTEPASESSECT和NG-OPTIONS的下拉列表。这是ng选项的HTML代码下拉列表:
<div class="col-xs-6">
Hours step is:
<select class="form-control" ng-model="hstep" ng-options="opt for
opt in table.hstep"></select>
</div>
<div class="col-xs-6">
Minutes step is:
<select class="form-control" ng-model="mstep" ng-options="opt for
opt in table.mstep"></select>
</div>
但是问题是当我使用上述代码时,下拉列表在单击下拉列表时无效,它不会给出项目的列表。
任何人都可以告诉这个ng选项语法是什么问题?
P.S。我想将此下拉菜放在Angular JS的模态窗口中。
这是我的JS代码:
var app = angular.module('myApp',
['ngTouch','ngAnimate','ui.bootstrap']);
app.controller("MainController",
['$scope','$uibModal',function($scope,$uibModal){
$scope.openModal = function(){
$scope.modalInstance = $uibModal.open({
templateUrl: 'modal.html',
controller :'ModalHandlerController',
size: 'lg',
});
}
$scope.mytime = new Date();
$scope.table = {
hstep: [1, 2, 3],
mstep: [1, 5, 10, 15, 25, 30]
};
$scope.hstep = 1;
$scope.mstep = 15;
}]);
app.controller(" modalhandlercontroller",function($ scope,$ uibmodalinstance)
{
$scope.ok = function(){
$uibModalInstance.close('save');
}
});
使用Angular-UI-Bootstrap模态,当您在此模态中创建模态时,默认情况下是$ Rootscope,因此您无法使用控制器中定义的所有范围变量。
doc:
范围(类型:$ scope) - 用于该的父范围实例 模态的内容。默认为$ rootscope
您需要指定scope
以使用控制器的范围:
$scope.table = {
hstep: [1, 2, 3],
mstep: [1, 5, 10, 15, 25, 30]
};
var modalInstance = $uibModal.open({
templateUrl: 'myModalContent.html',
controller: 'ModalInstanceCtrl',
scope: $scope /* <----- HERE to use the controller scope */
)}
或使用Resolve参数
您可以在resolve
选项参数中传递数据
$scope.table = {
hstep: [1, 2, 3],
mstep: [1, 5, 10, 15, 25, 30]
};
var modalInstance = $uibModal.open({
templateUrl: 'myModalContent.html',
controller: 'ModalInstanceCtrl',
resolve: {
table: function() {
return $scope.table;
}
}
});
您可以将其注入模式控制器:
app.controller('ModalInstanceCtrl', function($scope, $uibModalInstance, table) {
$scope.table = table;
});

请检查您的角版。
-
请检查您的控制台窗口中还有其他错误
-
请初始化
hstep
和mstep
模型对象,如下图。
其他范围您的代码非常完美。
angular.module("app",[]).controller("appContr",function($scope)
{
$scope.table = {
hstep: [1, 2, 3],
mstep: [1, 5, 10, 15, 25, 30]
};
});
