How to display a confirm box when entering a custom action.

#1 · December 23, 2024, 4:34 pm

I have a form where the employee needs to enter an amount, Once they have entered the amount they will press the custom submit button. The problem is that I want to display a confirm message prior to it being submitted. I have tried putting a confirm but even when I do a functionCallBack(true); the custom action still gets triggered. What Can I do to prevent the custom action from being called if the java confirm returns a false.

function(spContext, formContext, listColumnsInfo, currentItem, functionCallback) {

var ActualCost = formContext.fetchColumnValueUI("ActualCost");

if (ActualCost == 0) {

    if (confirm(window.confirm("You are submitting 0 dollars for your Actuals.\nIs this correct?")) == true) {

        functionCallback();

    else {

        functionCallback(true,"");

} else

    functionCallback();

Hi Archie,

Please use the provided script and let us know the results, this will prevent the custom action from being invoked if it returns as false

functionCallback();
