Filtering with Angular

Question

Filtering with Angular

I have a form that is structured into different sections as shown below:

education: {faculty: "", high_school: ""}
experience: {experience_1: "", experience_2: "", experience_3: ""}
personalInfo: {id: "", type: "", email: "", password: "", password_new: "", first_name: "", last_name: "",…}
skills: {skill_1: "", skill_2: ""}

All inputs are generated using ngRepeat directive.

<div ng-repeat="(key, val) in user" >
    <div ng-repeat="(k,v) in val | filter:filterBySection" class="formParameter" >

        <span class="param_label">
            {{k}}:
        </span>

     <span e-class="form-control " class="formParameterValue" editable-text="user.{{key}}.{{k}}" e-name="{{k}}">{{v}}</span>
    </div>   
</div>

My question is how can I create a filter to display only the selected section. For instance, if I click on the education button, it should only show 'faculty' and 'high school'

<li ng-repeat="(a,b) in user" ng-click="filterBySection = ?:{{a}}" ng-model="filterBySection"><a href="#">{{doc_param}}</a></li>

Your suggestions on implementing this feature would be greatly appreciated.

If you want to display different div containers based on a variable set by a button click event, you can achieve this using the "tab" variable in AngularJS. By assigning different values to "tab" upon button clicks, you can control which div is shown by using ng-show to check the value of "tab".

// Sample links or buttons
<a href ng-click="tab = 1"> Description</a>
<a href ng-click="tab = 2"> Specifications</a>

// Corresponding DIVs
<div class ="panel" ng-show="tab === 1">
   <h4>Description</h4>
   <p>{{product.description}}</p>
</div>
<div class ="panel" ng-show="tab === 2">
   <h4>Specifications</h4>
   <p>{{product.specification}}</p>
</div>

To enhance the functionality of filtering, it is recommended to develop a personalized filter instead of relying on the standard module. This custom filter can evaluate whether an item should be displayed based on specific criteria, utilizing the ng-show directive.

Maintain the association between your list items and the filterBySection model as you have been doing with the <li> elements.

Revamp the structure of the div containing the ng-repeat statement similar to this:

<div ng-repeat="(key,value) in data" ng-show="key | customFilter:filterBySection" class="customElement" >

Incorporate a custom filter within your AngularJS application by extending the angular.module object with a new filter function:

var app = angular.module("app", []);
app.filter('customFilter', function ($filter) {
    return function (input, section) {
        // Implement conditional statements such as
        if (section == 'Category' && (input == 'category1' || input == 'category2'))
        { return true; }
        // Add more conditions here...
    };
});
