Chi*_*itz 14 html javascript google-chrome angularjs
创建模板,我在一些HTML元素中有一些Angular代码:
<button id="btnMainMenu" class="button button-icon fa fa-chevron-left header-icon"
ng-if="(!CoursesVm.showcheckboxes || (CoursesVm.tabSelected == 'current') )"
...

我想调试ng-if条件来检查我的CoursesVm对象的值.例如,我如何在Chrome中执行此操作?

对于寻找Angular(2+)的人,请使用json管道
例如:
<span>{{ CoursesVm | json }}</span>
<textarea>{{ CoursesVm | json }}</textarea>

选项1: 修改您的代码 (对于Angular2 +和AngularJS)
Angular2 +
...在组件中添加此时间函数
checkIf(value: any){
debugger; //open the devtools and go to the view...code execution will stop here!
//..code to be checked... `value` can be inspected now along with all of the other component attributes
}

...在视图中:添加*ngIf带有创建的函数的,提供您要调试的值
<button *ngIf="checkIf(CoursesVm)">Button</button>

AngularJS
您可以将代码括在控制器函数的ng-if((!CoursesVm.showcheckboxes || (CoursesVm.tabSelected == 'current') ))内,然后调试该函数。
像这样:
//...controller
function checkIf(){
debugger; //open the devtools and go to the view...code execution will stop here!
//..code to be checked
}
<!--view supposing myCtrl is the alias for the controller here-->
<button id="btnMainMenu" class="button button-icon fa fa-chevron-left header-icon"
ng-if="myCtrl.checkIf()"
<!-- ... -->

选项2: 直接在chrome devtools中使用(对于AngularJS(某些人称为Angular 1))
捕获这样的范围:
var scope = angular.element(document.getElementById('#btnMainMenu')).scope();
像这样访问对象(假设此视图的控制器为myCtrl):
scope.myCtrl.CoursesVm
