Question

Just as the title says, I need help with javascript code that will open a webpage and fill out the form then submit the information.

Here is what I have currently:

var firstName = 'Billy';
var lastName = 'Bob';
var loginWindow = window.open('my website', 'loginWindow');
loginWindow.document.getElementById('fname').value=firstName;
loginWindow.document.getElementById('lname').value=lastName;
loginWindow.document.form.submit();

(I found it on another post).. but it does not work for me.

Answer 1

There may be XSS (Cross-Site Scripting) restrictions on this. But, there is a solution.

Browse the source code of the form you want, find the form tag’s action attribute (<form action="THIS STUFF HERE">...</form>), and then do one of the following in the scripting for your page:

1. Use it as the action of a new form and use the DOM to add hidden input elements with the names and values of the data you want to submit, then use .click() on the submit button to the new form.

2. Browse in some way to the action URL, but append ?name1=value1&name2=value2&name3=value3..., where name1 and value1, etc., are the names and values of the form fields you want to submit. If there is already something similar to this at the end of the action URL, just add on new &name=value pairs instead of appending a new question mark. (This could be done using an iframe with CSS display: none;.

Hope this helps!!
