How to add timestamp depending on the presence of File in the File input field

[Andrii]

To add timestamp depending on the presence of File in the File input field you need to add one additional HTML field and insert this snippet of code:

 

<script type="text/javascript">function addTimestamp (fileInputId, timestampInputId) {
    
 var fileInput = document.getElementById(fileInputId);
 fileInput.addEventListener('change', function () {
  
   if (fileInput.files.length !== 0 ){
    document.getElementById(timestampInputId).value = '[@cbTimestamp*]';
   }
 
 });

};

addTimestamp('File_Id_1', 'Date_Input_Id_1');
addTimestamp('File_Id_2', 'Date_Input_Id_2');
addTimestamp('File_Id_3', 'Date_Input_Id_3');
.
.
.
addTimestamp('File_Id_X', 'Date_Input_Id_X');
</script>

 

fileInputId: ID of the File field

timestampInputId: ID of the Date Field

 

You can add as many functions depending on the number of your file fields.
To find the ID of fields use Developer tools and "Inspect"

 

NOTE! 
You need to use the proper type of short date to save the value.
Example - 20/08/2018; dd/MM/ yyy

What if i wanted to put timestamp and text in two different filed?  Like if user uploaded a file in "Field_ID_1"  and automatically timestamp will be inputed in "Date_Input_ID_1" and automatically a text "New" will be inputted in a field "Remarks_ID_1". what will be the script in there to use?

To implement your workflow you can use this code:

 

<script type="text/javascript">function addTimestamp (fileInputId, timestampInputId, textInptId) {
    
 var fileInput = document.getElementById(fileInputId);
 fileInput.addEventListener('change', function () {
  
   if (fileInput.files.length !== 0 ){
    document.getElementById(timestampInputId).value = '[@cbTimestamp*]';
    document.getElementById(textInptId).value = 'New';
   }
 
 });

};

addTimestamp('fileInputId1', 'timestampInputId1', 'textInptId1');
addTimestamp('fileInputId2', 'timestampInputId2', 'textInptId2');
addTimestamp('fileInputId3', 'timestampInputId3', 'textInptId3');
.
.
.
addTimestamp('fileInputId_x', 'timestampInputId_x', 'textInptId_x');

</script>

 

Just find the IDs of the text fields using Developer Tools of the browser and insert these values instead of 'textInputId1', 'textInputId2'.....'textInputId_x'.
