Clear Input Value On Dynamically Add/remove Inputs

I have input element that can clear value when click the button. Also this input can be dynamically adding or remove input element. But I am stuck with when after add input eleme

Solution 1:

Use .on as shown below. The elements that are being added afterwards are not getting binded with the functions that you need.

Updated function

$(document).on("input", "input", function() {
  $(this).next(".btn_clear").toggle(!!this.value);
});
$(document).on("touchstart click", ".btn_clear", function(e) {
  e.preventDefault();
  $(this).prev("input").val("").trigger("input").focus();
});

// ADD , Remove inputvar counter = 1,
  custom = $('#custom');
$(function() {
  $('#add_field').click(function() {
    counter += 1;
    var newRow = $('<div class="row' + counter + '"><span class="wrap_input"><input id="exception_' + counter + '" name="" type="text"><button class="btn_clear">clear</button><button class="remove-text-box">Remove</button></span></div>');
    custom.append(newRow);
    (function(index) {
      newRow.find('.remove-text-box').click(function() {
        custom.find('.row' + index).remove();
      });
    })(counter);
  });
});

// clear input value 

$(document).on("input", "input", function() {
  $(this).next(".btn_clear").toggle(!!this.value);
});
$(document).on("touchstart click", ".btn_clear", function(e) {
  e.preventDefault();
  $(this).prev("input").val("").trigger("input").focus();
});

.btn_clear {
  display: none;
}

Solution 2:

Try to use the following code

// ADD , Remove inputvar counter = 1,
    custom = $('#custom');
$(function() {
    $('#add_field').click(function() {
        counter += 1;
        var newRow = $('<div class="row' + counter + '"><span class="wrap_input"><input id="exception_' + counter + '" name="" type="text"><button class="btn_clear">clear</button><button class="remove-text-box">Remove</button></span></div>');
        custom.append(newRow);
        (function(index) {
            newRow.find('.remove-text-box').click(function() {
                custom.find('.row' + index).remove();
            });
        })(counter);

        // call this method after row creationsetTimeout(function() {
            clearInputValue();
        }, 0);
    });
});

// clear input valuefunctionclearInputValue() {
    $('.wrap_input').each(function() {
        var $inp = $(this).find("input"),
            $cle = $(this).find(".btn_clear");
        $inp.on("input", function() {
            $cle.toggle(!!this.value);
        });
        $cle.on("touchstart click", function(e) {
            e.preventDefault();
            $inp.val("").trigger("input").focus();
            $inp.change();
        });
    });
}

This is another example of how it can be done.

functionadd(){
      //Add
      $(".elements" )
        .append( "<div>\
        <input type='text' class='myinput'>\
        <button class='clear'>clear</button>\
        <button class='remove'>remove</button>\
        </div>" );
       
      init()
      
    }

    functioninit(){ 
      //Removevar x = document.getElementsByClassName('remove')
      for(var i = 0; i< x.length; i++){
          x[i].addEventListener("click", function(e){
            e.target.parentNode.remove()
          })
      }
      
      //Clearvar y = document.getElementsByClassName('clear')
      for(var i = 0; i< y.length; i++){
          y[i].addEventListener("click", function(e){  
            e.target .parentNode.querySelector("input").value = ''; 
            //after clear hide .clear button 
            e.target.parentNode.querySelector(".clear").style.display = "none";
          })
      }
      
      //Show hide .clear button var z = document.getElementsByClassName('myinput')
      for(var i = 0; i< z.length; i++){
         z[i].addEventListener("input", function(e){    
            if(e.target.value.length > 0){
              e.target.parentNode.querySelector(".clear").style.display = "inline";
            }else{
              e.target.parentNode.querySelector(".clear").style.display = "none";
            }
         })
      }
      
    }

    init();

.clear{ 
      display:none;
    }
