Export only filtered data into csv in angular smart table - angularjs

Question

We have implemented a report table using angular smart table.When user applied search criteria using st-search , we need to export all items into csv.We have used ng-csv directive for exporting. When use st-table array collection, the only first page data is getting.That mean total 7 records after filtering and first page showing 5 items, only this data(5 items) is exported.How can export all filtered data?
<table class="table table-striped" st-table="displayed">
<thead>
<tr>
<th st-sort="firstName">first name</th>
<th st-sort="lastName">last name</th>
<th st-sort="birthDate">birth date</th>
<th st-sort="balance">balance</th>
<th >email</th>
</tr>
<tr>
<th>
<input st-search="firstName" placeholder="search for firstname" class="input-sm form-control" type="search"/>
</th>
<th colspan="4">
<input st-search placeholder="global search" class="input-sm form-control" type="search"/>
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in displayed">
<td>{{row.firstName | uppercase}}</td>
<td>{{row.lastName}}</td>
<td>{{row.birthDate | date}}</td>
<td>{{row.balance | currency}}</td>
<td><a ng-href="mailto:{{row.email}}">email</a></td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="5" class="text-center">
<div st-pagination="" st-items-by-page="5" st-displayed-pages="10"></div>
</td>
</tr>
</tfoot>

Answer 1

You can have access to the filtered collection through the table controller api. So you just need to create a directive which requires the stTable controller:
.directive('stExport',function(){
return {
require:'^stTable',
link:function(scope, element, attr,ctrl){
element.bind('click',function(){
alert(ctrl.getFilteredCollection().length);
})
};
}
have a look at that running example
