如何访问angularjs指令中链接函数内函数的作用域? [英] How to access scope in a function inside link function in angularjs directive?

问题描述

这可能不是 angularJS 的问题，但我的机智到此为止.代码如下所示:

This might not be an angularJS problem but I am at my wit's end here. The code is shown below:

prep.directive('resultgraph', function () {
  return {
    restrict: 'A',

    link: function (scope, element, attrs) {
        //** scope accessible here **

        DomReady.ready(function () {
            ThreeBox.preload([
                '/scripts/lib/snippets.glsl.html',
            ], function () {

               //....scope not accessible here

如何访问 'preload' 回调函数中的作用域，它说此处无法访问作用域?

How do I access the scope inside the callback function of 'preload', where it says scope is not accessible here ?

推荐答案

如果您需要准备好 DOM，您可以在链接函数中执行此操作(范围将是可访问的):

If you need the DOM to be ready you can do this inside the link function (the scope will be accessible):

$timeout(function(){
    alert('DOM ready');
    //** scope accessible here **
});
