How to make the value of a text box the same as a variable?

[Murtaza Javaid]

Hi, I'm trying to learn Javascript. I've been learning for a long time and decided maybe I'll do my first useful project.

This code is a bookmarklet for quickly uploading to tinypaste.com. It is meant to be used in a browser without any HTML. It ('s purpose is) gets your selection into a variable (x) then goes to tinypaste.com and paste the text in the main text box. (id: 'input_text')
It would be nice to give a prompt during the process for the title as well ('paste_title') and to automatically 'click' send, then get the url of the paste and alert it to you.

javascript:
 
x = "" + (window.getSelection ? window.getSelection() : document.getSelection ? document.getSelection() : document.selection.createRange().text); 
 
window.location= "http://tinypaste.com/";
 
alert (x);
 
document.getElementsById("input_text").value= (x);
 

At the moment, the code gets the text properly, goes to tinypaste, but doesn't change the value of input_text.


When I do start at tinypaste, select the text, then use the bookmarklet, it changes the value fine, then as soon as that happens, it goes to tinypaste again.

Doesn't this mean that its changing the value BEFORE going to tinypaste? I'm suspecting that is the problem and how do I fix this?

Any help would be appreciated. Thanks.

You can open a new window instead. Once the location changes, I don't think there's any way to get the rest to run

How do I do that...?
Won't the rest of the code then still run in the current webpage?

I've not really played much with bookmarklets, so I'm not sure if it'd work, but you can keep a reference to the opened window and then set the value of the text box on the opened window.

Hmm... Ok how do you open a new window directly from javascript, if this is even possible?
(to my knowledge it isn't)

With window.open(). See some examples of bookmarklets here (though, it mentions Opera, most should work in all browsers).

Edit: looking at your original URL, I noticed this page which should help solve your problem. I think you'll find that if you're on another domain, you'll have permissions issues, so the best way would be to adapt their own bookmarklet.
