Angularjs: Show search result in typeahead if no match is found for the entered string
I am using Angular UI-bootstrap typeahead.
I have HTML
<input type="text"
ng-init="selectedCrossFormFieldText = selectedCrossFormFieldText || {}"
ng-model="selectedCrossFormFieldText[fieldId]"
placeholder="Auto-complete data from field of form"
empty-typeahead
ng-trim="false"
typeahead="crossFormField.id as crossFormField for crossFormField in getCrossFormFieldData(fieldId, $viewValue) | filter:$viewValue:optionComparator"
typeahead-template-url="views/blocks/cross_form_data_typeahead.html"
typeahead-on-select="addCrossFormField(fieldId, $item, $model, $label)"
typeahead-loading="loadingCrossFormField[fieldId]"
typeahead-min-length="0" class="form-control" />
and
Script:
.then(function (response) {
console.log('DataForTypeahead', response);
return response.data;
});
When I type, it displays the appropriate options in the typeahead popup. But what should I do to show when no matches are found on the same No Matches popup?

You can check the size of the response.data file. If it's 0, push the item into the array:
.then(function (response) {
console.log('DataForTypeahead', response);
if (response.data.length === 0) {
response.data.push({
label: 'No matches found'
})
}
return response.data;
});
You might want to change your code like:
typeahead="crossFormField.id as crossFormField.label for crossFormField in getCrossFormFieldData(fieldId, $viewValue) | filter:$viewValue:optionComparator"
