html input field value setter not working properly in chrome and safari using jquery -

i trying set html input field value on keyup event using jquery.

<input style="width: 45%;" type="text" name="user_phone" value="" placeholder="your phone number" /> 

first tried using .val() setter this.

$(document).ready(function(){   $('input[name=user_phone]').keyup(function() {     var number = $('input[name=user_phone]').val();     if (!number.contains('(') && !number.contains(')') && number.length === 2) {                     $('input[name=user_phone]').val('(' + number + ')');     } else if (number.contains('(') && !number.contains(')') && number.length === 3) {         $(this).val(number + ')');     } else if (!number.contains('(') && number.contains(')') && number.length === 3) {         $(this).val('(' + number);     }   }); }); 

this worked fine in firefox in chrome , safari didn't work. suggested in other questions tried way using .prop() instead of .val()

$(document).ready(function(){   $('input[name=user_phone]').keyup(function() {     var number = $('input[name=user_phone]').val();     if (!number.contains('(') && !number.contains(')') && number.length === 2) {                     $('input[name=user_phone]').prop('value','(' + number + ')');     } else if (number.contains('(') && !number.contains(')') && number.length === 3) {         $(this).prop('value', number + ')');     } else if (!number.contains('(') && number.contains(')') && number.length === 3) {         $(this).prop('value', '(' + number);     }   }); }); 

the same thing happened, it worked expected in firefox not in safari or chrome.

it giving number.contains not function in console. suggest use $.contains below works , good!!

demo here

$(document).ready(function(){     $('input[name=user_phone]').keyup(function() {         var number = $('input[name=user_phone]').val();         if (!$.contains(number,'(') && !$.contains(number,')') && number.length === 2) {                         $('input[name=user_phone]').val('(' + number + ')');         } else if ($.contains(number,'(') && !$.contains(number,')') && number.length === 3) {             $(this).val(number + ')');         } else if (!$.contains(number,'(') && $.contains(number,')') && number.length === 3) {             $(this).val('(' + number);         }     }); });
