我正在尝试在我的代码中实现一个简单的Angular ng-show,但我似乎无法使其工作。我附上下面的代码。
HTML
<div ng-repeat="question in data.questions track by $index" ng-if="question.visible" class="slide">
<md-radio-group ng-model="question.selectedAnswer" ng-if="vm.showSliderChecker">
<md-radio-button ng-repeat="ans in question.answer track by $index" ng-value="ans._id"
ng-click="radioBtnClick({qId: question._id, ansId: ans._id})">{{::ans.description}}
</md-radio-button>
</md-radio-group>
<div class="wrapper" ng-show="vm.showSliderChecker">
<div class="toggle_radio">
<input type="radio" class="toggle_option" id="first_toggle" name="toggle_option" >
<label for="first_toggle" class="widthEighth" ng-repeat="ans in question.answer track by $index" ng-value="ans._id"
ng-click="radioBtnClick({qId: question._id, ansId: ans._id}); showSliderClickedMessage()"><p> {{$index+1}} </p></label>
</div>
</div>
</div>
角度控制器 vm.checkSliderForDisplay = checkSliderForDisplay;
function initController(){
checkSliderForDisplay();
}
function checkSliderForDisplay() {
if($stateParams.testType === "Stress_management"){
vm.showSliderChecker = true;
console.log("The value of slider checker is true and here's proof ----> ");
console.log(vm.showSliderChecker);
}
else{
vm.showSliderChecker = false;
console.log("Alas, the slider checker is just a lot of false advertising and nothing more.");
console.log(vm.showSliderChecker);
}
}
initController();
现在问题在于:
控制台日志显示在控制台上,但两个div都保持隐藏状态。我在这个网站上寻找了一个解决方案并尝试了一些组合,认为我错过了一些细节,但我似乎可以使它工作。
答案 0 :(得分:0)
当您使用Controller时,因为synstax vm是您可以引用范围内控制器的名称。
如果您的代码在不同的闭包中运行,例如从控制器构造函数运行,您可能需要以不同的方式引用它。
看起来这段代码是在Controller构造函数中调用的,所以&#34; vm&#34;在那里不会成为一个定义的变量。你应该使用&#34;这个&#34;代替:
IMessageActivity
如果你在js文件的顶部添加function checkSliderForDisplay() {
if(this.testType === "Stress_management"){
this.showSliderChecker = true;
console.log("The value of slider checker is true and here's proof ----> ");
console.log(this.showSliderChecker);
}
else{
this.showSliderChecker = false;
console.log("Alas, the slider checker is just a lot of false advertising and nothing more.");
console.log(this.showSliderChecker);
}
}
,你应该得到一些警告。
