  3. Great plugin !!!

  4. Thanks,
    To change design locate the <link> tag in <head>
    <link href="http://ajax.googleapis.com/ajax/libs/jqueryui/x.y.z/themes/cupertino/jquery-ui.css" rel="stylesheet" />

    and replace the theme cupertino/ with any of the following -
    # base/
    # black-tie/
    # blitzer/
    # cupertino/
    # dark-hive/
    # dot-luv/
    # eggplant/
    # excite-bike/
    # flick/
    # hot-sneaks/
    # humanity/
    # le-frog/
    # mint-choc/
    # overcast/
    # pepper-grinder/
    # redmond/
    # smoothness/
    # south-street/
    # start/
    # sunny/
    # swanky-purse/
    # trontastic/
    # ui-darkness/
    # ui-lightness/
    # vader/

    This is the easiest way to do it. If you are familiar with css you can write your custom css to include after the above link and to write custom design and colors. The calculator is already made up with classes you can use to write css.

    1. Orvyl can you clear it more. Btw you need to have jquery script and than jquery UI script/css imported first before you import calculator.js in your html and there you can edit the link tag to change the theme.

      Let me know if it solves your query.

      Best,

  11. How can I show it directly on top of everything so it doesn't move my elements around when shown ?

    ReplyDelete

    1. put it inside an element having position: relative and the calculator itself should have position: absolute

  12. I have it in this div :


    I initialize it with :
    $('#calcdiv').calculator({movable:true,resizable:true, width:160,defaultOpen:true});

    And I'm using the css copy/pasta from the calculator.css file from the download link.

    It still pushes my elements down :-)
    Any ideas ? (I had to obfuscate with dots due to anti-html checks of the blog software)

    1. Can you show me it hosted on a temp server?

      Delete
  13. Sorry, no.

    But I ended up putting it inside a jquery dialog. Good enough. :-)


    Although I find it strange that it only captures keypad numbers.

    ReplyDelete
  14. Thank you sharing this code. It saved hours of work. Firefox works fine for me however, in IE 8 the numbers do not display - the header title displays fine. Any idea? I used IE Developer Tool to debug and when I change the position to relative the numbers display but the format is lost. Can you help?
