Limit the number of characters in the angular expression and include ellipses at the end

Question

Limit the number of characters in the angular expression and include ellipses at the end

I am looking to implement a restriction on the amount of text displayed by an angular expression that returns a block of text.

The length of the text can vary greatly, ranging from 1 character to over 3,000. I want to limit the displayed text and potentially add ellipses at the end, using either an image or something like <div>...</div>.

What would be the most effective approach for achieving this?

Is there an angular method for accomplishing this, such as a filter?

Or would it be better to use a directive instead?

<div text-length-limit>{{description}}</div>

Answer №1

If you need to achieve this, you can use the following code snippet:

{{description | limitTo: 5}}<span ng-show="description.length > 5">...</span>

The limitTo function restricts the string to a specified length (in this case, 5) and if the original string exceeds that length, it will display an ellipsis (...) after the first 5 characters.

One convenient use of filters is to transform a value into another value while maintaining the same type. For example, you might need a filter that truncates a string with an ellipsis (...) if it exceeds a certain length.

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

    app.filter('ellipsis', function() {
        return function(val, maxLength) {
           if (val && val.toString().length > maxLength) {
               return val.toString().substring(0, maxLength) + '...';
           }
           return val;
        };
    });

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.js"></script>
<div ng-app="app">
  Enter text longer than 5 characters: <input type="text" ng-model="text" /> {{text | ellipsis:5}}
</div>
