- Default values entered when the form was created in the Form Designer
- Values from an XML document(s) sent in the Post request for the form or OnInit.

Certain characters such as % need to be URL encoded. The w3schools.com website describes in detail the reason certain characters must be encoded when used in Urls. And it also contains a tool that lets you enter your string and converts it to a properly encoded string. For example if your value is '% complete' this must be written as '%25 complete'. The single and double quote characters themselves must be escaped with the escape the frevvo escape character '!'. For example the string 'Nancy's Horse' must be written as 'Nancy!'s Horse'. If the '!' is missing from the string the apostrophe will be mistaken as the end of string character. |

The onSubmit function allows you to copy the data from the frevvo form (when that frevvo form is submitted) into your HTML form. Then you can use your own JavaScript on your HTML page to process that data (for example save it somewhere else at your own convenience and time, etc.)
The embedding page and must frevvo must be in the the same domain/origin.Typically this means same uri scheme, host and port.
The value of onInit must be an in scope javascript function. This onInit javascript function will be called before the form is instantiated. For example &onInit=getData will cause to cause frevvo to call the getData() javascript function. The onSubmit function will be called after the submit button is clicked.
Here is a sample html page an embedded script embedded frevvo script tag and an onInit javascript function. The script The frevvo script tag copied was from the Share dialog and the &onInit Url parameter was appended. Each xml document is placed inside a container element (input, textarea or any other element such as a div) and assigned and xml id. In this example there is a single xml document placed inside a <textarea> tag.
...
- The Url parameter &onInit=getData used matches exactly the name of a javascript method in the html page also named getData().
- The xml data is also embedded in the html page in the <textarea> tag.
- The <ns:form> content came directly from a prior form submission and was copied out of the submission the frevvo submission repository's Documents tab.

This is how the form looks when initialized via the onInit method. The particular form used in this sample has a repeat control. By default this form has a single repeating item. When initializes When frevvo initializes the form with repeating data returned from the getData() method it auto creates the additional items. This form also contained a Item Added Rule which is why there is also a value in the Quantity field.
