Catalog Client Script help

[huyjor]

Hello Team

I have this simple catalog client script. I don't see any problem with this but I'm not sure why it's not working. Thanks for your help. 
Type: Onchange

variable name: end_date

function onChange(control, oldValue, newValue, isLoading) {

    if (isLoading || newValue == '') {

        return;

    }

    //Start date should not allow past date

    var courseStartDate = new Date(g_form.getValue('start_date')); //get start date selected by the user

    var courseEndDate = new Date(g_form.getValue('end_date')); //get end date selected by the user.

    if (courseEndDate.valueOf() < courseStartDate.valueOf()) {

        g_form.addErrorMessage('The End Date should be after the Start Date');

        g_form.clearValue('courseStartDate');

        return false;

    }

}

Can you try this?

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    //Start date should not allow past date
    var courseStartDate = new Date(g_form.getValue('start_date')); //get start date selected by the user
    var courseEndDate = new Date(g_form.getValue('end_date')); //get end date selected by the user.

    if (courseEndDate < courseStartDate) {
        g_form.addErrorMessage('The End Date should be after the Start Date');
        g_form.clearValue('end_date');
    }
}

Hi @huyjor ,

Try to log the info and check if your get any response

if (courseEndDate < courseStartDate ) {

        g_form.addErrorMessage('The End Date should be after the Start Date');

        g_form.clearValue('courseStartDate');

}

You don't have to use .value(), seems like it's a Gpt code ...

I hope this helps...

Nope, It's not working. It's weird that my code is working on the platform client script but not on the catalog client script. It makes no sense.
