如何预填充文本字段并单击URL的提交按钮

Question

I want to open a URL, eg http://www.facebook.com . How do I open it from one page and set the values of the input field to my credentials and auto click the login button. I found the following code snippet:

<p>Your name:
<br /><input name="name" id="name" /></p>

<p>Your email:
<br /><input name="email" id="email" /></p>


<script>

var hashParams = window.location.hash.substr(1).split('&'); // substr(1) to remove the #
for(var i = 0; i < hashParams.length; i++){
var p = hashParams[i].split('=');
     document.getElementById(p[0]).value = decodeURIComponent(p[1]);;
}

That produces this URL: www.xyz.com/contact.html#name=some_text&email=more%20text&username=john&age=23 . (no credits taken).

But I am not sure where to enter the URL to hit.

Answer 1

Inspect the page and find the login field in the HTML.

For Facebook, use:

document.getElementById("email").innerHTML = "YourEmail";
document.getElementById("pass").innerHTML = "yourpass";

In the URL, try adding

<script>document.getElementById("email").innerHTML = "YourEmailhere";
document.getElementById("pass").innerHTML = "yourpasshere";</script>

after Facebook.com
