How to compare two fields using Javascript [Read All]

In this article we will describe how to create a simple form with RSform! with two email fields. The following script will be used to compare the value of these fields so you can get a confirmation that the data inputed by the user is correct.

You can start by creating a new form with the following settings:

Form Title: Compare
Form Name: Compare

The next step is to populate the form with the following fields:

1. Email field 1
   Field id: email1
   Field Title: Email1
   Validation: email
   Field Type: text
   
   
2. Email field 2
   Field id: email2
   Field Title: Email2
   Validation: email
   Field Type: text
   
   
3. Submit button
   Field id: submit
   Field Title: Compare
   Validation: --none--
   Field Type: submit button
   

  Save the new fields created.

On the "Form Style" tab type the following code right after " action="{action}" ":

        onsubmit="return checkEmail(this);"
        
At the the end of form tag (after ) you will have to type the following JavaScript:

 
function checkEmail(theForm) {
   if (theForm.email1.value != theForm.email2.value)

{
  alert('Those emails don\'t match!');
  return false;
  }

else {
  return true;
  }
  return true
}

Click "Save" and that's it.
