Ways to showcase angular scope data within a placeholder while avoiding the use of angular expressions

Initially, I utilized angular expressions {{value}} to present values within elements. However, upon noticing that unrevealed expressions continue to display on the front end during loading delays, I switched to using ng-bind.

<div>
  <h1>Hello <span ng-bind="name"></span></h1>
</div>

By opting for ng-bind instead of {{ }}, it effectively prevents unrendered {{ }} from appearing, replacing them with empty rendered elements instead.

However, now I am encountering a similar issue with an input placeholder

<input type="text" ng-model="name1"  placeholder=" Welcome {{name}} . Enter your question" ></input>

The problem persists during loading delays. The presence of curly braces is unnecessary at such moments. So, how can this problem be rectified?

Answer №1

In order to address the challenge of preventing curly braces from appearing during delays in loading, one possible solution is to ensure that your JavaScript is loaded only after all styles and HTML content have been fully loaded.

One way to achieve this is by placing the script tags at the bottom of the body section of your HTML document.

If you want to resolve this issue, consider implementing a custom directive.

  var module = angular.module('solution', []);

module.controller('solutionCtrl', function($scope) { 
    $scope.example = 'your sample text';

})
.directive('ngCustomDirective', function() {
  return {
    scope: {
      customText: '=ngCustomDirective'
    },
    link: function(scope, element, attrs) {
    	scope.$watch('customText',function() {
        element[0].placeholder = scope.customText;
      });
    }
  }
});
