how to get changed fields in the presubmit event handler

zyq105

In the editor preSubmit event handler, I want to display the field XYZ which value has been changed.

editor.on('preSubmit', function (e, data, action) {
// here I need to find the list of column names XYZ ... which value has been changed
return confirm("The cloumns [XYZ, ...] have changed value, Are you sure want to submit the change?");
});

Take a look at this:

Instead of stringifying the fields you can look at them individually. Instead of "preBlur" you could use "preSubmit"

It helps. Thanks!

forgot to mention: If you want to compare the Editor form values I wouldn't use "preSubmit" because at that point in time the form is no longer available which makes it a bit tricky.

Just use "initSubmit" because then you can compare the form fields.

Here is an an example from my own coding in which I compare the value of just one field which I save in a global variable on "initEdit" and then check on "initSubmit".

editor
    .on('initEdit', function ( e, node, data, items, type ) {
        old_follow_up_days = this.field("contract.follow_up_days_creditor").val();
    })
    .on('initSubmit', function ( e, action ) {
        if ( action === 'edit' ) {
            if ( old_follow_up_days != this.field("contract.follow_up_days_creditor").val() ){
                this.set({'contract.creditor_exp_notified': 0});
            }
        }
    });
