Issues observed when implementing replaceWith() to replace text tags with input field on a web page

Just a simple EDIT request. I want to modify the headers so that when I click on the "edit" icon, the header will change to a text field and the "edit" icon will switch to a "save" icon.

    
    $('#editheader').click(function(e){

        var category = $(this).closest("h3").text();        

        $( this ).replaceWith( "<a href=''> <i class='fa fa-save' aria-hidden='true' style='color:green'></i> </a>"  );
        $( this ).closest("h3").replaceWith( "<input value='" + category + "' >" );        

        e.preventDefault();
    });

<h3 class="panel-title"> Letters To Investors
   <a href="#" id="editheader">
       <i class="fa fa-pencil" aria-hidden="true" style="color:green"></i>
   </a>

<h3 class="panel-title"> Tax Documents
   <a href="#" id="editheader">
       <i class="fa fa-pencil" aria-hidden="true" style="color:green"></i>

Answer №1

I added a form to my HTML element and implemented the following code:

    $('#editheader').click(function(e){

        var category = $(this).closest("h3").text();   

        $(this).hide();
        $(this).closest("h3").hide();

        $('#editForm').show();
        $('input[name=category]').val(category);     

        //$( this ).replaceWith( "<a href=''> <i class='fa fa-save' aria-hidden='true' style='color:green'></i> </a>"  );
        //$( this ).closest("h3").replaceWith( "<input value='" + category + "' >" );        

        e.preventDefault();
    });
</script>

Enhance your code with the following tips:

Avoid using the same id for buttons as IDs must be unique; consider using classes instead.
Instead of replacing the a tag, change the class for the icon.
Utilize a span element to easily target the text within the h3.
Use a class as a flag to differentiate between edit and save actions.

$('.editheader').click(function(e) {
  if(!$(this).hasClass('save')){
    var category = $(this).siblings("span").text();
    $(this).siblings('span').replaceWith("<input value='"+category+"'/>");
   } else {
    var category = $(this).siblings("input").val();
    $(this).siblings('input').replaceWith("<span>"+category+"</span>");
   }
   $(this).toggleClass('save');
   $('i',this).toggleClass('fa-save fa-pencil');
   e.preventDefault();
});

Answer №3

When using replaceWith(), keep in mind that it removes the element you are referring to. To resolve this issue, simply switch the lines of code.

$('.editheader').click(function(e) {
      e.preventDefault();

      let $h3 = $(this).closest("h3");
      let category = $(this).closest("h3").text();

      $h3.toggleClass('edit');

      if ($h3.hasClass('edit')) {
          const newCategory = $h3.children('input').val();
          $h3.children('input').remove();
          $h3.children('span').text(newCategory);
        } else {
          $h3.children('span').text('');
          $h3.prepend("<input value='" + category + "' >");

          $(this).children('i').removeClass('fa-pencil').addClass('fa-save');
        }
      });

Answer №4

When it comes to changing the parent element through the child, things can get tricky. A good solution is to enclose the text you want to change within a placeholder element like span, and then replace it with the desired input element.

Another issue arises when trying to replace the a href element with another while other codes depend on the original element. To tackle this, simply rearrange the order of JQuery codes so they execute in a logical sequence.

Lastly, having identical IDs for multiple a href elements can lead to conflicts. It's recommended to use classes instead for better organization.

    
    $('.editheader').click(function(e){

        var category = $(this).closest("h3").text();        

$( this ).prev().replaceWith( "<input type='text' value='" + category + "' >" ); 
        $( this ).replaceWith( "<a href=''> <i class='fa fa-save' aria-hidden='true' style='color:green'></i> </a>"  );
               
        e.preventDefault();
    });
