Q:

Jquery filter table if fits into input range

Question:
I have a HTML  with type number i want to ge the value using jQuery create a range by adding 10% on either side then checking if each row falls in the range if not hide the row.
Code:
HTML
<input type="number" id="myPrice" onkeyup="myPriceFunction()" placeholder="Enter amount.." title="Type in a amount" min="0">

JavaScript/jQuery
$(document).ready(function(){
  $("#myPrice").on("keyup", function() {
       priceLow = $(this).val() * 0.9;
       priceHigh = $(this).val() * 1.1;
  });
}); 

JS fiddle
https://jsfiddle.net/nx30zqjd/7/
Other:
I am using:
.addClass('discarded').hide();

.removeClass('discarded').show();

to hide and show rows
Expected Results:
I want the range to be created with priceLow and priceHigh then get price column get rid of $ and check if it falls within range if not hide using code above.
Update:
I added
    $(this).closest('tr').removeClass('discarded').show();
  } else {
    $(this).closest('tr').addClass('discarded').hide();
  }

however then this shows nothing because i don't check discarded rows, if i remove the check for discarded rows it doesn't apply my search to the range not sure if there is a easy way to have both but it seems to be ok for the moment
If you need any more information please ask.
Thanks

A:

You can use this, you just need to iterate and get the values and then check, based on that you can hide and show.
$("#myPrice").on("keyup", function() {
    if ($(this).val() === '') {
      $("#myTable tr").show();
      return;
    }
    priceLow = $(this).val() * 0.9;
    priceHigh = $(this).val() * 1.1;
    $("#myTable tr td:nth-child(2)").each(function(e) {
      var value = this.textContent.replace('$', '');
      if (value >= priceLow && value <= priceHigh) {
        $(this).closest('tr').show();
      } else {
        $(this).closest('tr').hide();
      }
    })
  });

$(document).ready(function() {

});
$(document).ready(function() {
  $("#myPrice").on("keyup", function() {
    if ($(this).val() === '') {
      $("#myTable tr").show();
      return;
    }
    priceLow = $(this).val() * 0.9;
    priceHigh = $(this).val() * 1.1;
    $("#myTable tr td:nth-child(2)").each(function(e) {
      var value = parseFloat(this.textContent.replace('$', ''));
      if (value >= priceLow && value <= priceHigh) {      
        $(this).closest('tr').removeClass('discarded').show();        
      } else {
        $(this).closest('tr').addClass('discarded').hide();        
      }
    })
  });
});
