How to remove the last value from a list collector on change of another variable?

[Sujatha V M]

Hello Team, 

I have variable A (list collector) which holds a default value. I would like to add another value to the same variable A on change of another variable. 

If 'yes' - Variable A [Default Value + New Value]

If 'no' - Variable A [Default Value]

That new value is a 'sys_id'. 

I'm trying with slice syntax and it erases all the values on call of script include.

Hi @Sujatha V M ,

Hope you are doing well.

Please try the below code -

// If Yes
var list1 = g_form.getValue("test_list");
var arr = [];
arr = list1.split(",");
arr.push("replace with the sys_id to push"); // replace with the value to push
g_form.setValue("test_list",arr);    // default value + newValue
   

Please mark this response as correct or helpful if it assisted you with your question.

Thanks for the response. But there is slight change on the requirement. 

Instead of a default value in the variable A, its a dynamic value now based on another variable. 

i.e Variable X is selected -> Variable A [list collector] needs to be populated.

then if "Yes" on variable Y -> Append the new value to the Variable A along with the existing one. 

If "No" on variable Y -> Remove the appended value from Variable A and keep the existing one.

HI @Sujatha V M 

A client-script prototype for your requirement, please update the variables as required -

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

    // Get the 'yes/no' variable (assuming its name is 'yesNoVariable')
    var yesNoVariable = g_form.getValue('yesNoVariable');

    if (yesNoVariable === 'yes') {
        // Get the current value of the list collector variable A
        var currentValue = g_form.getValue('variableA');

        // Check if the new value is not already present in the list
        if (!currentValue.includes(newValue)) {
            // Add the new value to the existing value, separated by a comma
            var updatedValue = currentValue + ',' + newValue;

            // Set the updated value back to the list collector variable A
            g_form.setValue('variableA', updatedValue);
        }
    } else if (yesNoVariable === 'no') {
        // If 'no' is selected, set the list collector variable A to its default value
        var defaultValue = 'default_value'; // Replace 'default_value' with the actual default value
        g_form.setValue('variableA', defaultValue);
    }
}
