How to check if any field value changes on the form?

[Ipshita Kumari]

Hi Team,

Hope you all are doing well.

I have requirement to check if any field values have been modified on the form and make "Suggestion" field mandatory if any of the field value changes.

Can you please suggest how can I achieve this requirement ?

Hi Ipshita,

You can use below

g_form.modified;

If you just want to do a check to see if any value on the entire form changed (a dirty form), you can use ‘g_form.modified’ in an ‘onSubmit’ client script like this…

function onSubmit() {
  if(g_form.modified){
    return confirm("Values on the form have changed.\nDo you really want to save this record?");
  }
}

If you just want to check for changes to a few specific fields then you could use something like this in an ‘onSubmit’ client script…

function onSubmit() {
  var field1 = g_form.getControl('caller_id'); //Get the 'Caller' field control
  var field2 = g_form.getControl('short_description'); //Get the 'Short description' field control
 
  //See if the 'changed' attribute on either field is true
  if(field1.changed || field2.changed){
    return confirm("Values on the form have changed.\nDo you really want to save this record?");
  }
}

function onSubmit() {
  var field1 = g_form.getControl('caller_id'); //Get the 'Caller' field control
  var field2 = g_form.getControl('short_description'); //Get the 'Short description' field control
 
  //See if the 'changed' attribute on either field is true
  if(field1.changed || field2.changed){
    return confirm("Values on the form have changed.\nDo you really want to save this record?");
  }
}

This gives an error - onSubmit script error: TypeError: Cannot read properties of undefined (reading 'changed'):
function () { [native code] }
