On Change Client Script for Catalog Item Multi Row Variable Set

[Scott29]

Hello, I have the below multi row variable set. How can I have the "Total Weight" and "Total Price" automatically calculate once "Unit Weight" is populated.

"Total Weight" = "Quantity" x "Unit Weight"

"Total Price" = "Quantity" x "Unit Price"

Hi,

You can achieve this by utilizing onChange client script in MRVS

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

    var quauntiy = g_form.getValue('u_quantity');;
    var unit_price = g_form.getValue('u_unit_price');
    var unit_weight = g_form.getValue('u_unit_weight');

    if (unit_weight != '') {
        var total_weight = quauntiy * unit_weight;
        var total_price = quauntiy * unit_price;
        g_form.setValue('u_total_weight', total_weight);
        g_form.setValue('u_total_price', total_price);
    } else {
        g_form.showFieldMsg('u_unit_weight', '...Your own message'); // optional step

    }
}

Add a client script on your MRVS that runs when Unit Weight is changed. In the client script, set the values of Total Weight and Total Price.
