Can Yokohama Employee Center Share Catalog Script Among Different Scripts

[John Spencer]

Hello All,

I have 10 fields on a catalog item -- require numeric input.  I have not found a way to have the function that does the input validation appear just in one place and called from there.  I include the code I am using below.  

The onChange and then the function code itself.   Right now that code is repeated in the in each 'onChange' field.   The 'input validation' code works very well.  I deliberately disallow '$' and ',' (commas).

Any advice / recommendation appreciated.

This is the onChange function:

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

    validateDollarAmount('recurring_cost_year_02', oldValue, newValue, isLoading);

}

Below is the code that is repeated:

function validateDollarAmount(fieldName, oldValue, newValue, isLoading) {

    if (isLoading) {

        return;

    }

    var raw = (newValue || '').trim();

    if (raw === '') {

        g_form.setValue(fieldName, '0.00');

        return;

    }

    // Only digits and one optional decimal with max 2 places

    var moneyPattern = /^\d+(\.\d{1,2})?$/;

    if (!moneyPattern.test(raw)) {

        alert('The input: ' + raw + ' is not a valid number. Enter a valid amount like 0, 12, or 12.34. Do not use $ or commas.');

        g_form.setValue(fieldName, oldValue || '0.00');

        return;

    }

    var amount = Number(raw);

    if (!Number.isFinite(amount) || amount < 0) {

        alert('Negative numbers are not allowed.');

        g_form.setValue(fieldName, oldValue || '0.00');

        return;

    }

    var normalized = amount.toFixed(2);

    if (newValue !== normalized) {

        g_form.setValue(fieldName, normalized);

    }

}
