[英]$watch is not calling inside tabs in angularjs?
Hi All,
在我的示例中,我创建了两个输入文本框,一个在选项卡外部,另一个在内部。 我为两者创建了一个监视功能。 外面的设备工作正常,但选项卡内的手表功能不起作用。 两个地方都有相同的编码类型,只是我不知道为什么一个在起作用而另一个在不起作用。
谁可以帮我这个事?
angular.module('components', []). directive('tabs', function() { return { restrict: 'E', transclude: true, scope: {}, controller: [ "$scope", function($scope) { var panes = $scope.panes = []; $scope.select = function(pane) { angular.forEach(panes, function(pane) { pane.selected = false; }); pane.selected = true; } this.addPane = function(pane) { if (panes.length == 0) $scope.select(pane); panes.push(pane); } }], template: '<div class="tabbable">' + '<ul class="nav nav-tabs">' + '<li ng-repeat="pane in panes" ng-class="{active:pane.selected}">'+ '<a href="" ng-click="select(pane)">{{pane.title}}</a>' + '</li>' + '</ul>' + '<div class="tab-content" ng-transclude></div>' + '</div>', replace: true }; }). directive('pane', function() { return { require: '^tabs', restrict: 'E', transclude: true, scope: { title: '@' }, link: function(scope, element, attrs, tabsCtrl) { tabsCtrl.addPane(scope); }, template: '<div class="tab-pane" ng-class="{active: selected}" ng-transclude>' + '</div>', replace: true }; }) .controller('sample', function($scope){ $scope.cancel = function(){ console.log("cancel") } $scope.$watch('FirstName', function() { console.log("FirstName") // fetch(); }); $scope.$watch('FirstName1', function() { console.log("FirstName1") // fetch(); }); //Here I need to Change Selected Tab })

您应该在ng-model中使用点。 这里参考
因此,您的代码将与以下代码相同:
在javascipt文件
.controller('sample', function($scope){
$scope.user = {};
$scope.cancel = function(){
console.log("cancel")
}
$scope.$watch('user.FirstName', function() {
console.log("FirstName")
// fetch();
});
$scope.$watch('FirstName1', function() {
console.log("FirstName1")
// fetch();
});
//Here I need to Change Selected Tab
})
在HTML文件中:
<pane id="FirstTab" title="First Tab">
<div><div class="form-group">
<label for="text">First Name</label>
<input type="text" required ng-model="user.FirstName" class="form-control" id="FirstName">
</div>
<div class="form-group">
<label for="text">Middle Name</label>
<input type="text" required ng-model="user.MiddleName" class="form-control" id="MiddleName">
</div>
<div class="form-group">
<label for="text">Last Name</label>
<input type="text" required ng-model="user.LastName" class="form-control" id="LastName">
</div>
</div>
</pane>
您可以以其他方式执行此操作..也可以使用ng-change ..它会监视模型中的任何更改并相应地调用该函数。 添加它而不是$ watch。
$scope.change = function() {
console.log("FirstName")
}
在模板中,按如下所示调用ng-change
<input type="text" required ng-model="FirstName" ng-change="change()" class="form-control" id="FirstName">
