Adding JavaScript to your Form

You have the choice of two different approaches: 

Method 1 -  Create a file with your JavaScript . Name it custom.js. The custom.js file can be uploaded to an application or on the tenant level. 

1. 1. If a designer uploads a custom.js file to an application, it is only available for forms/flows in that application. Refer to  Method 1a below for the details.
   2. If a superuser/tenant admin uploads custom.js to the tenant, then the custom.js will be available to all forms/flows in the tenant. Refer to Method 1b below for the details.

Method 2 -  Add a Message Control that contains your JavaScript. Refer to  Method 2 below for the details.

...

1. Your custom JavaScript must contain the comment // frevvo custom JavaScript as the first line of the file or the upload will not be successful. Note the CustomEventHandlers Javascript JavaScript object. Application level custom js requires that you create a JavaScript object called CustomEventHandlers.

   Here is an example of code that will add dashes to a Social Security number control as the user is typing it in. See Custom JavaScript Examples for information on this sample code. Notice the JavaScript comment is the first line in the script file.
   
   
   
   

2. Login to  as a designer user. Click the Edit icon for the application where you want to use the JavaScript. Click on the Script tab located on the left menu.
   
   

   
   
   

3. Browse your hard drive for your script file, Click Upload. Your file will be uploaded and it will display with the name Custom Script even though your script file may have another name.

   Warning
   Be Aware aware that existing JavaScript files will be overwritten. Download the existing custom.js file, append your new code to existing code then upload the combined file if you want to preserve the existing JavaScript

   
   

4. If you need to modify the script, you must download it, make your modifications and then upload it again. When you download the script by clicking on the   Download icon, it will be named custom.js.  

5. Once you have uploaded the JavaScript, it is available for all forms/flows in the application. Remember to add the CSS class name to your form controls or your JavaScript may not work.

   Here is an image of an Employee Information form using uploaded JavaScript to enter dashes in the Social Security Number field while the user is entering the data.
   
   
   

...

Uploading custom.js files with the same class name on the application and tenant levels is not recommended. This could result in unpredictable behavior. When two custom event handlers are bound to the same event (tenant level and app level), there is no guarantee which handler is called first. This is under the control of the JavaScript engine. Rewrite your JavaScript to avoid this situation.

Method 2

Follow these steps to add JavaScript to your form using the Message control:

...

 <script>
        /* <![CDATA[ */
        code goes here
        /* ]]> */
</script>

var MyUtil = {
    today: function() {
        var d = new Date();
        var dd = d.getDate();
        if (dd < 10) dd = '0' + dd;
        var mm = d.getMonth() + 1;
        if (mm < 10) mm = '0' + mm;
        var yyyy = d.getFullYear();
        return String(mm + "-" + dd + "-" + yyyy);
    }
}
