Toggle table column visibility in AngularJS by using a dropdown selection in the first column

Implementing angularjs

I have a situation where I have a table with two columns. The first column is linked to an array, while the second column contains a dropdown menu.

My goal is to display or hide 5-6 additional columns (containing text and dropdowns) based on the selection made in the dropdown of the second column.

I attempted the following code snippet:

  <table class="table table-bordered">
    <thead>
    <tr>
        <th>Name</th>
        <th>Value</th>
        <th></th>
    </tr>
    </thead>
    <tbody>
    <tr ng-repeat="item in items">
       <td >{{item.name}}</td>
       <td >  
          <select name="utype" class="form-control input-medium"  ng-model="utype">
                  <option value="">---Please select---</option>
                  <option ng-repeat="type in types" >{{type.text}}</option>
          </select></td>
      <td><span ng-hide="utype =='Type1' || utype!=undefined" >{{item.value}}</span></td>
      <td><button class="btn btn-small" ng-click="edit(item)">Edit</button></td>
    </tr>
    </tbody>
  </table>

ng-hide="utype =='Type1' || utype!=undefined"

Unfortunately, this code only works correctly the first time. Subsequent attempts fail to hide the columns as intended.

If anyone could provide guidance on how to resolve this issue, I would greatly appreciate it.

Answer №1

After initializing <code>ng-model="utype"
, the condition utype!=undefined will always return true.

<td><span ng-hide="utype =='Type1' >{{item.value}}</span></td>

In my opinion, it is better to use === instead of '=='. For more information, refer to this Stack Overflow answer.
For example, ng-hide="utype ==='Type1'
