Having trouble with filtering JSON data in AngularJS?

I'm sorry if this question has already been answered. I tried looking for solutions on other websites, but couldn't understand them. I am attempting to filter JSON data within the ng-repeat function, but whenever I try to input something, it doesn't display anything. Any help or direction would be greatly appreciated. You can see an example of what I mean in this jsbin:

Answer №1

To adjust your filter criteria, use the following method:

ng-repeat="story in storytitle | filter:{'title.$text':searchquery}"

This will specifically search for the search term within the title.$text property.

Remember to initialize your searchquery as empty in the controller:

$scope.searchquery = '';

Answer №2

One issue is that the filter is unable to access nested properties.

It is unable to filter stories.title.$text.

Possible solutions:

  • Create your own custom filtering function.
  • Find a way to expose the content to be filtered in a property that is not nested. For example, instead of stories.title.$text, make it accessible as stories.title_text.

Check out this functional JS Bin: http://jsbin.com/esAteYI/2/edit

I have made two adjustments:

  1. Established a stories.$text property that includes the contents of both stories.title.$text and stories.teaser.$text.

  2. You can specify the property on which the filtering should be carried out. Take note of how I modified the ng-model attribute of the search input field to

    <input ng-model="searchquery.$text" />

    By specifying the .$text property, the filter will focus only on it, saving time and avoiding unnecessary checks on other properties.
