Question

I have element like this :

<input type="text" onkeyup="filter()" id="filter_data">

<div id="body">
  <div class="child"> Text 1 </div>
  <div class="child"> Text 2 </div>

I want to search the div text by input value.

I can search the data but.. how to show "data Not found" inside div body, if all child div is not have any data like input value.

This my fiddle.

Answer 1

Working fiddle.

You could add an increment a variable (result in my example) to know if there's any data found or not then show/hide the message :

if( result === 0 ){
    $('.empty_div').removeClass('hide');
}else{
    $('.empty_div').addClass('hide');
}

function filter() {
  var value = $('#filter_data').val();
  var div_class = $('#body').find(".child");
  var result = 0;

  div_class.hide();
  div_class.each(function() {
    if ($(this).text().toUpperCase().indexOf(value.toUpperCase()) != -1) {
      $(this).show();
      result++;
    }
  });

  if (result === 0) {
    $('.empty_div').removeClass('hide');
  } else {
    $('.empty_div').addClass('hide');
  }
}

.hide {
  display: none;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" onkeyup="filter()" id="filter_data">
<div id="body">
  <div class="child"> Text 1 </div>
  <div class="child"> Text 2 </div>
  <div class="child"> Text 1 </div>
  <div class="empty_div hide">No Data Found</div>
</div>

Add one more div and fiddle: https://jsfiddle.net/thecreativedev/0k8ustrv/62/

JS

function filter() {
    var value = $('#filter_data').val();
    var div_class = $('#body').find(".child");
    $('.nomatched').html('').hide();
    div_class.hide();
    var i =0;
    div_class.each(function() {     
       if ($(this).text().toUpperCase().indexOf(value.toUpperCase()) != -1) {
          $(this).show();
          ++i;
        }
    });
    if(i == 0){
        $('.nomatched').html('No matched data Found').show();
    }
}

HTML

<input type="text" onkeyup="filter()" id="filter_data">
<div id="body">
  <div class="child"> Text 1 </div>
  <div class="child"> Text 2 </div>
  <div class="child"> Text 1 </div>
  <div class="nomatched" style="display:none"></div>
</div>
