Adding textbox value into href image link

Hello

I have tried looking this up on the internet but i havent been able to find an exact answer.

I would like the value from my text box to appear in the href link of a clickable image.
The value from the textbox entry will be the IP address i want to browse to when clicking on the image.

Here is my code so far;

Code:

<body>

<table width="200" border="1">
  <tr>
    <td width="9">&nbsp;</td>
    <td width="104"><a href='index.php?ip='+form3.ip.value><img src="up.png" width="97" height="104" align="middle" /></a></td>
    <td width="65">&nbsp;</td>
  </tr>
<td><form id="form3" name="form3" method="post" action="">
      <label for="ip"></label>
      <input name="ip" type="text" id="ip" value="192.168.0.2" />
    </form></td>

When i click on the link it simply refreshes the current page and changes the url to localhost/index.php?ip=

I also need this link not to open. In other words, once i have click on the image, i want to silently browse to the textbox value (ip address) in the background.

All help would be appreciated. Im in mech engineering, and i need this to control a robot over wifi

Thanks alot.

okay i have figured out how to open a link from a textbox.

Although i still dont know how to open a webpage silently without a window opening.
Any ideas? thanks

When you say "silently" are you referring to something like AJAX?

You could "silently" visit the page that way (and just discard the result) if your only goal is to essentially "ping" the server (or your robot's IP).

I want it to load up the webpage in the background without displaying anything.

For example, the link will be 192.168.0.2/?forwards
Where the forwards part will make the robot move forwards.
I dont want to open a separate window every time i send a command to the robot.
Im not sure if pinging the address would send the command. I could try though.
How could this be implemented?
thanks for the help
