Comparing two fields on service catalog form

[anushadande1793]

Hi 

Need help on below requirement. Can someone help on this?

we need to compare two fields and one field value shouldn't be exceeded and it should be negative always.

we have written onchange client script to allow only negative values but not able to compare with other field and restrict with less values. From the below screenshot, Accum should allow only less values than cost and always negative values. Any inputs really helps me alot

Thanks & Regards,

Anusha

Hello @anushadande1793 ,

Please try to check with the below modified script once and see how it works for you.

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

    g_form.hideFieldMsg('accum'); // Clear previous messages

    // Ensure the value is numeric
    if (isNaN(newValue)) {
        g_form.showFieldMsg('accum', 'Please enter a valid numeric value.', 'error');
        g_form.clearValue('accum');
        return;
    }

    // Convert the new value to a number for validation
    var accum = parseFloat(newValue);

    // Ensure the value is negative
    if (accum >= 0) {
        g_form.showFieldMsg('accum', 'Value must be negative.', 'error');
        g_form.clearValue('accum');
        return;
    }

    // Fetch and validate the cost field
    var costValue = g_form.getValue('cost');
    if (!costValue || isNaN(costValue)) {
        g_form.showFieldMsg('accum', 'Please ensure the Cost field has a valid value.', 'error');
        return;
    }

    var cost = parseFloat(costValue);

    // Ensure Accum is less than Cost
    if (accum >= cost) {
        g_form.showFieldMsg('accum', 'Value must be less than the Cost field.', 'error');
        g_form.clearValue('accum');
    }
}

I shared script below.

Sharing updated script again

try that and share your updates, it should be onChange on Accum variable

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

    g_form.hideFieldMsg('accum');
    // Ensure Accum is negative
    if (parseInt(newValue) >= 0) {
        g_form.showFieldMsg('accum_to_retire', 'Accum must be a negative value', 'error');
        g_form.clearValue('accum_to_retire');
        return;
    }

    // Compare Accum with Cost
    var cost = g_form.getValue('cost');
    if (parseFloat(newValue) >= parseFloat(cost)) {
        g_form.showFieldMsg('accum_to_retire', 'Accum must be less than Cost', 'error');
        g_form.clearValue('accum_to_retire');
    }
}

Use this onChange script for Accum variable

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

     g_form.hideFieldMsg('accum');
    // Ensure Accum is negative
    if (parseInt(newValue) >= 0) {
        g_form.showFieldMsg('accum', 'Accum must be a negative value', 'error');
        g_form.clearValue('accum');
        return;
    }

    // Compare Accum with Cost
    var cost = g_form.getValue('cost');
    if (parseFloat(newValue) >= parseFloat(cost)) {
        g_form.showFieldMsg('accum', 'Accum must be less than Cost', 'error');
        g_form.clearValue('accum');
    }
}

Hi @anushadande1793 

Create onChange client script for accum variable

var accum = g_form.getValue('accum'); 
var cost = g_form.getValue('cost');

if (accum >= 0) {
g_form.setValue('accum', -Math.abs(accum)); 
}

if (accum >= cost) {
g_form.setValue('accum', cost - 1);
alert("Accum should be less than Cost.");
}
}
