Dealing with angular two way binding to take DOM Rendering time

89 views Asked by At

I can't see my loading label for fastest two way binding.

I have a flag for show and hide loading label. but am unable to see the loading label. because angular is rendering(binding) very speed.

Expectation 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?

Expectation 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.

I made following snippet for the issue and you can easily make a snippet answer.

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

You can try to sync your DOM / Application like in this simple demo fiddle. It ensures that the ng-repeat did rendered all items before displaying it. Meanwhile loading is displayed. I think it's a little hack but it works like a charm if you realy want to sync. your DOM & JS-Application. IMO this it not needed because E2E binding is async all the time and its fine.

View

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