Date onChange Client Script Issue

[Community Alums]

Hi,

I have a scenario where I have to see that start date should not be greater than end date. For this, I have created two client scripts. I am getting error here. Kindly help.

First Client Script

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

	if(newValue )
    var start = g_form.getValue('delegation_start');
    //g_form.addInfoMessage(start);
    var end = g_form.getValue('delegation_end');
    //g_form.addInfoMessage(end);
    if (start > end) {
        g_form.addErrorMessage('Delegation Start date cannot be after End date');
        g_form.clearValue('delegation_end');
    }
}

Second Client Script

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

	var start = g_form.getValue('delegation_start');
	//g_form.addInfoMessage(start);
	var end = g_form.getValue('delegation_end');
	//g_form.addInfoMessage(end);
	if(start > end){
		g_form.addErrorMessage('Delegation Start date cannot be after End date');
		g_form.clearValue('delegation_end');
	}


}

As soon as I select this,

I am getting the error 'Delegation Start date cannot be after End date'.

Hi @Community Alums ,

Use below onchange client script for both.

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

    var start = g_form.getValue('delegation_start');
    var end = g_form.getValue('delegation_end');

    if (start && end) { // Ensure both dates are present
        if (new Date(start) > new Date(end)) { // Compare Date objects
            g_form.addErrorMessage('Delegation Start date cannot be after End date');
            g_form.clearValue('delegation_end'); // Clear the invalid End Date
        }
    }
}

tested it, working as expected.
