Hi,

I have 2 input field, and I want to filter the table against the 2 input fields using OR instead of And.

However I'm unable to do it with the code below, the table return all field regardless what I type in the input, anyone can help me with it?

<script type="text/javascript">
 function checking($scope) { 
 $scope.check = function(tableField,input) { 
 if (input.type == "or"){
 if (tableField.name.indexOf(input.name) > -1 || input.name == null || tableField.created_by.indexOf(input.createdby) > -1 || input.createdby == null ){
 return true
 }
 else{
 return false
 }
 }
 } 
 }
</script>

<table ng-table="table">
 <tbody>
 <tr ng-repeat="car in cars" ng-controller="checking" ng-show="check(car,externalFilters)">
 <td data-title="'Name'">
 {{car.name}}
 </td>
 <td data-title="'Created by'">
 {{ car.created_by || 'unknown' }}
 </td>
 </tr>
 </tbody>
</table> 

What I have tried:

I have tried removing input.name == null and input.createdby == null, and it works, however on load no data will be shown, as the script return false.
