javascript - 处理 Angular 双向绑定(bind)以占用 DOM 渲染时间

转载作者：行者123 更新时间：2023-11-28 04:11:43

我看不到最快双向绑定(bind)的加载标签。

我有一个用于显示和隐藏加载标签的标志。但我看不到装载标签。因为 Angular 的渲染(绑定(bind))速度非常快。

期望 1:-

So I want to show and hide the isloading flag while rendering callback is start and end. I hope this is the proper way to my solution. Is it possible?

期望 2:-

And I have check with stack overflow, then are suggest to use $timeout. But I don't think this is a good solution. But if we can't do my first expectation then I can go with the $timeout way. But here I don't set approximate time to $timeout function, I would be set exact DOM rendering time on the $timeout function.

我为该问题制作了以下代码片段，您可以轻松地做出代码片段答案。

angular.module("app",[]).controller("controllerApp", function($scope)
{
$scope.IsLoading=true;
// now the data binding and rendering is starting 
$scope.data = [

最佳答案

您可以尝试同步您的 DOM/应用程序，就像这个简单的 demo fiddle 一样。 。它确保 ng-repeat 在显示之前渲染了所有项目。同时显示loading。我认为这是一个小技巧，但如果你真的想同步，它就像一个魅力。您的 DOM 和 JS 应用程序。 IMO 这不是必需的，因为 E2E 绑定(bind)始终是异步的，而且没问题。

<div ng-controller="MyCtrl">
  <span ng-show="isLoading">loading...</span>
  <table ng-repeat="obj in data" ng-show="!isLoading">
    <tr>
      <td>
        <b> {{obj.FieldGroupName}}</b>
        <table style="border:solid 1px dashed; border-color:black">
          <tr ng-repeat="objChild in  obj.cocVersionDataFieldCollection" 
              ng-init="checkLoadingState($index)">
            <td>
              {{objChild.FieldName}}
              <td>
                {{objChild.FieldName}}

                <td>
                  {{objChild.FieldName}}
                </td>
                <td>

          </tr>

AngularJS 应用

myApp.controller('MyCtrl', function($scope, $timeout) {

  $scope.isLoading = true;

  // now the data binding and rendering is starting 
  $scope.data = [{
