我正在学习AngularJS中的指令,我看到了以下代码:
var app = angular.module('app', []);
//creating custom directive syntax
app.directive("myDir", function () {
return {
restrict: "E", //define directive type like E = element, A = attribute, C =
class, M = comment
scope: { /
每次将值更新为控制器时,我都想更改更新指令。
不幸的是,我无法从指令中访问范围值。
下面是指令的代码:
myApp.directive( 'raphael', function ($compile, $document, $timeout) {
return {
link: function ( scope, element, attrs ) {
var paper = new Raphael(element[0], 600, 600);
// I need it right here !
我试过用手表:
scope: {variable: '=
我在ng-if中调用一个控制器函数,如下所示,但checkUserExamEnrollment函数被重复调用。有没有人能建议一下代码的错误之处?
查看:
<div ng-if="checkUserExamEnrollment()== 0">Sample Data here if ng-if true</div>
控制器:
$scope.checkUserExamEnrollment = function()
{
var url = "http://localhost/api/examnew";
