jQuery code to detect whether form fields have the default value when a checkbox is unchecked












1














How could I rewrite this jquery code to compact it in a more elegant form:






$(document).ready(function(){
$('input[name="table_exist"]').click(function(){
if($('input[name="table_name"]').val()=='users' && $('input[name="table_exist"]').is(':checked'))
{
$('input[name="table_name"]').val('');
}
else if($('input[name="table_name"]').val()=='' && !$('input[name="table_exist"]').is(':checked'))
{
$('input[name="table_name"]').val('users');
}

if($('input[name="user_id"]').val()=='user_id' && $('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_id"]').val('');
}
else if($('input[name="user_id"]').val()=='' && !$('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_id"]').val('user_id');
}

if($('input[name="user_name"]').val()=='user_name' && $('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_name"]').val('');
}
else if($('input[name="user_name"]').val()=='' && !$('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_name"]').val('user_name');
}

if($('input[name="user_email"]').val()=='user_email' && $('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_email"]').val('');
}
else if($('input[name="user_email"]').val()=='' && !$('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_email"]').val('user_email');
}

if($('input[name="user_pass"]').val()=='user_pass' && $('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_pass"]').val('');
}
else if($('input[name="user_pass"]').val()=='' && !$('input[name="table_exist"]').is(':checked'))
{
$('input[name="user_pass"]').val('user_pass');
}

<h2>DB Table</h2>

<p>
Activate the slider if you already have your own database table created!
</p>

<div class="inputCheckBox">
<input type="checkbox" name="table_exist" />
</div>

<p>
Edit here only if you have your own predifined table header names!
</p>

<div class="inputBox">
<input type="text" name="table_name" value="users" required />
<label>Table Name</label>
</div>

<div class="inputBox">
<input type="text" name="user_id" value="user_id" required />
<label>User ID</label>
</div>

<div class="inputBox">
<input type="text" name="user_name" value="user_name" required />
<label>User Name</label>
</div>

<div class="inputBox">
<input type="text" name="user_email" value="user_email" required />
<label>User E-mail</label>
</div>

<div class="inputBox">
<input type="text" name="user_pass" value="user_pass" required />
<label>User Password</label>
</div>

<div class="inputBox">
<input type="text" name="joining_date" value="joining_date" required />
<label>User Added Date</label>
</div>

<button type="submit" name="btn-install">

</button>

</form>





The whole process is to identify if the fields have the default values when a checkbox is unchecked. If the state is changed to checked then empty all fields to input custom information/values. If unchecked again it returns the initial values.

          There're multiple ways to do that. You should use a loop.



          I've wrote a small script, that would do the job. I do not know if the if block is correct but you should easily fix that with this base.






          $(document).ready(function(){
          $('input[name="table_exist"]').click(function(){
          var table_exist_checked = $('input[name="table_exist"]').is(':checked');

          var fields = [
          'table_name',
          'user_id',
          'user_name',
          'user_email',
          'user_pass',
          'joining_date',
          ]; // Your field names

          // iterate over all fieldnames
          for(var index of fields) {
          var fieldName = fields[index]; // extract current fieldName
          var $elem = $('input[name="' + fieldName + '"]'); // save current element so we do not need to repeat

          // This is ur if-else. I do not exactly know if this is correct
          if($elem.val() == fieldName && table_exist_checked){
          $elem.val('');
          } else if($elem.val()=='' && !table_exist_checked){
          $elem.val(fieldName);
          }
          }

          }); });

            Following @ArayniMax example I fixed it this way:



            $(document).ready(function(){
            $('input[name="table_exist"]').click(function(){

            var inputCheck = $('input[name="table_exist"]').is(':checked');

            var fields = {
            'table_name': 'users',
            'user_id': 'user_id',
            'user_name': 'user_name',
            'user_email': 'user_email',
            'user_pass': 'user_pass',
            'joining_date': 'joining_date'
            };

            $.each(fields, function(key, value) {

            var fieldInput = $('input[name="' + key + '"]');

            if(fieldInput.val()==value && inputCheck)
            {
            fieldInput.val('');
            }
            else if(fieldInput.val()=='' && !inputCheck)
            {
            fieldInput.val(value);
            }
            });
            });
            });


            Thank you for your help everyone!

                      Following @ArayniMax example I fixed it this way:



                      $(document).ready(function(){
                      $('input[name="table_exist"]').click(function(){

                      var inputCheck = $('input[name="table_exist"]').is(':checked');

                      var fields = {
                      'table_name': 'users',
                      'user_id': 'user_id',

                      };

                      var fieldInput = $('input[name="' + key + '"]');
