How can Add the button to the form and make it visible only when the specific field is changed

2

Add the code to the refresh method or on field change.

E.G:

frappe.ui.form.on('Task', {
    refresh: function(frm) {
        // add custom button code
    },
    field_name: function(frm){
        // add custom button code
    }
});

but after the field is saved its not showing

Dear @Govind_Gupta

frappe.ui.form.on('Your DocType', {
    refresh: function(frm) {
        // Hide the button initially
        frm.remove_custom_button('Your Button');
    },
    your_fieldname: function(frm) {
        // Show the button when the specific field is changed
        if (frm.doc.your_fieldname) {
            frm.add_custom_button('Your Button', function() {
                // Your button action here
                frappe.msgprint('Button clicked!');
            });
        } else {
            frm.remove_custom_button('Your Button');
        }
    }
});
