How to copy and paste values from an input type="button"?

I have to copy and paste the values of input type="button" (ie value="1.25", value="3.50") from a lot of pages. Is it possible using jquery or greasemonkey?

<td>
    <input type="button" onmouseout="btnGiocataOut(开发者_开发问答this)" onmouseover="btnGiocataOver(this)" onclick="aggiungiScommessa(6659, 12, 22, 1, 125)" value="1.25" class="ris">
</td>
<td class="valore" colspan="1">Over</td>
<td>
    <input type="button" onmouseout="btnGiocataOut(this)" onmouseover="btnGiocataOver(this)" onclick="aggiungiScommessa(6659, 12, 22, 2, 350)" value="3.50" class="ris">
</td>

JQuery bookmarklet - and then in firebug console:

$("input[type='button']").each(function() { console.log($(this).val()); });

Yes, if you want to grab button values automatically, without futzing with Firebug on every page, Greasemonkey can do that.

Here's a script that should get you started. Be sure to adjust the @include statements to match your target sites.

//
// ==UserScript==
// @name            Button value grabber
// @namespace       Gambling
// @description     Grabs button values.
// @include         *
// @require         http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js
// ==/UserScript==
//

$(document).ready (Greasemonkey_main);

function Greasemonkey_main ()
{
    /*--- Create a container div and area for the values.  It will be styled and
        postioned with CSS.
    */
    $("body").append
    (
          '<div id="GM_PopUpDiv">'
        +   '<h3>Button Values on this page:</h3>'
        +   '<form id="GM_ContForm"><textarea id="GM_BtnValues"><\/textarea><\/form>'
        + '<\/div>'
    );

    //--- Make it almost invisible when not moused over.
    $('#GM_PopUpDiv').hover
    (
        function () { $(this).stop (true, false).fadeTo (50, 1); },
        function () { $(this).stop (true, false).fadeTo (900, 0.15); }
    );

    /*--- Copy the button values.   Fine-tune the selector to taste.
        For example, input.ris[type='button']
    */
    var NumRows = 0;
    var BtnVals = $("input[type='button']").map (function(J) {
                    NumRows = J;
                    return this.value;
                } ).get ().join ('\n')
                ;

    /*--- Paste the values into the textarea and adjust the height to the data
        (within the min/max set by CSS, below).
    */
    $("#GM_BtnValues").text (BtnVals). css ('height', NumRows + 4 + 'em');
}


//--- This is just CSS to make the new stuff look "purty".

I use Firebug and jQuery in one-off situations like this. I load jQuery dynamically if necessary: $('<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" />').appendTo(document.body);. That goes in the Firebug console. Then I would use something like $('input').each(function() { console.log($(this).val()); });, and it would print out a list that I could easily copy. I would repet these steps for every page.
