javascript scripts

hello

I would like to hit a keyboard shortcut
and parse the current webpage and then do stuff in the
webpage (eg autosave links that contain a specific
string, autosave images, autoclick specific buttons
etc etc)

can you tell me how to do that?

I use Opera Browser

thanks

Welcome to TSDN.

For keyboard shortcuts, see this example. It gives you the keycode of the key pressed. You can also see this ref. for alt/shift/ctrl keys.

You can simulate button clicks with the click() method, see link.

thanks

can you give me a guided example of a script that will recognize a button and click it whenever it appears (whenever I visit a webpage that it contains it) ?

thanks

You could look for all input elements:

var allInput = document.getElementsByTagName("input");

and check for their type. If it's button, then call the click() method.

ummm

can you tell me the script that whenever I visit google.com it will autoput "something" inside the search form, it will select and then it will autoclick the "I am feeling lucky button" ?

thanks

Look at the source code of the page. Find the name or id of the search box and likewise for the button. Then it should be trivial to set the value and click the button respectively.

Say the id is "searchbox", then:

document.getElementById("searchbox").value='the value to set';

If the id for the button is "searchButton", then to click:

document.getElementById("searchButton").click();

thanks much appreciated

so to autoclick google search button whenever I visit google.com, I should use this script:

document.addEventListener('DOMContentLoaded',function() {
document.getElementById("btnG").click();
}

but it doesnt work :s

Is this Google page in an iframe? You need to access the iframe first, see this page.

Well, in that case, it shouldn't be possible, but since you're using Opera, you can use something called User Javascript, see link.
