Add state from zip code

Description

Adds the "State" label and the text form prefilled with "CA" if the zip code of California is entered. It can be extended by using API to prefill "State" when entering the zip code.

(function()
{
    var document = Api.GetDocument();
    var allForms = document.GetAllForms();
    //California Zip Codes regex
    const zipRegex = /^9[0-5][0-9]{3}$/;
    
    allForms.forEach(form => {
        if(form.GetFormKey() == "ZipCode") {
            var input = form.GetText();
            //If the zip code is Californian, add the "State" label with the text form indicating "CA"
            if(zipRegex.test(input)) {
                const stateForm = allForms.find(item => item.GetFormKey() === "State");
                if(stateForm == null) {
                    var stateTextForm = Api.CreateTextForm({"key": "State", "tip": "State", "required": false, "placeholder": "State", "comb": true, "maxCharacters": 2, "cellWidth": 3, "multiLine": false, "autoFit": false});
                    stateTextForm.SetText("CA");
                    var paragraph = Api.CreateParagraph();
                    paragraph.AddTabStop();
                    paragraph.AddText("State: ");
                    paragraph.AddElement(stateTextForm);
                    document.InsertContent([paragraph]);
                }
                else {
                    stateForm.SetText("CA");
                }
            }
        }
    });
})();
