  • What's the best way to write a maintainable web scraping app?

    - by Benj
    I wrote a perl script a while ago which logged into my online banking and emailed me my balance and a mini-statement every day. I found it very useful for keeping track of my finances. The only problem is that I wrote it just using perl and curl and it was quite complicated and hard to maintain. After a few instances of my bank changing their webpage I got fed up of debugging it to keep it up to date. So what's the best way of writing such a program in such a way that it's easy to maintain? I'd like to write a nice well engineered version in either Perl or Java which will be easy to update when the bank inevitably fiddle with their web site.

  • Is having a lot of DOM elements bad for performance?

    - by rFactor
    Hi, I am making a button that looks like this: <!-- Container --> <div> <!-- Top --> <div> <div></div> <div></div> <div></div> </div> <!-- Middle --> <div> <div></div> <div></div> <div></div> </div> <!-- Bottom --> <div> <div></div> <div></div> <div></div> </div> </div> It has many elements, because I want it to be skinnable without limiting the skinners abilities. However, I am concerned about performance. Does having a lot of DOM elements refrect bad performance? Obviously there will always be an impact, but how great is that?

  • How do I make faint words in search bar that go away when you click/type?

    - by Razor Storm
    So, for instance facebook's search bar has faint word that says "search", but when you click on the bar, it becomes blank and you may begin typing, when you click away the "search" goes back. Similarly, SO's ask a question title box has faint words that go away when you start typing. I'm not too sure what this effect is called, but I'm wondering if theres a jQuery plugin that helps to achieve this. This isn't particularly difficult to program, but I thought why reinvent the wheel if someone already made a plugin for it.

  • Focus CSS tag in Internet Explorer 8

    - by Sam
    This is driving me nuts. http://www.cssdrive.com/index.php/examples/exampleitem/focus_pseudo_class This is an example of using the hover pseudo-class. Works fine in Chrome and IE. When I save locally it works fine in Chrome but won't work in IE. What am I doing wrong!? <link rel="Stylesheet" href="style.css" /> <form> <p>1) Name:<br /> <input type="text" size="40"></p> <p>2) Email address:<br /> <input type="text" size="40"></p> <p>3) Comments:<br /> <textarea rows="5" name="comments" cols="45" wrap="virtual"></textarea></p> <p><input id="actualsubmit" type="submit" value="Submit"></p> </form> style.css: input:focus, textarea:focus{ background-color: lightyellow; }

  • How to design websites for all display sizes

    - by katie bekell
    I like to use a lot of unique graphics on my pages, which often results in making different page sizes depending on available screen width/height. Here are two examples: http://www.uvm.edu/~areid/homesite/ - the image floats at the bottom of my screen but on a larger browser, the image floats near the middle making it look off. It looks best when the bottom of the window aligns with the bottom of the image www.stevenlebel.com - it loads two different pages depending on what monitor size is detected. This seems like a lot of redundant coding. My question is, how can I make sliced/Photoshop images transition well to different screen sizes. Does Photoshop allow you to make DIVS instead of tables? Can i make each of the slices created by Photoshop grow/shrink when the browser window size changes? If anyone has any input on creating websites like this I would be very interested to hear what they have to say. Thanks Katie

  • Align 3 images in a div , left-centre-right, uneven margin

    - by Adrian
    I could find a work around for this if I wanted but it seems wrong and am trying to learn to code in a neater way. Basically I have a div with 3 images in it, the div is 700px, and each image is 220px, So thats 660px with two 20px gaps left and right of the centre image, and the outside images going all the way to their end of the div. Is there a quicker way of doing this without setting up seperate ids for each image? .contentpictureblock { float:left; } .contentpictureblock img { margin-right:20px; } <div class="contentpictureblock"> <img src="http://..."> <img src="http://..."> <img src="http://..."> </div> Doing the above^ pushes the third image to the next line, which is understandable. I know I could always make seperate divs for each image, and adjust the margins for each one but Im just wondering is there a quicker one off overflow type command that I could apply to the above? It would mean the right margin would be on all the images but would have no effect on its positioning in the last image. Thanks for the help.

  • how to put header authentication into a form using php?

    - by SkyWookie
    Hey guys, for the page I am doing needs a login authentication using Twitter (using tweetphp API). For test purposes I used this code below to do a successful login: if (!isset($_SERVER['PHP_AUTH_USER'])){ header('WWW-Authenticate: Basic realm="Enter your Twitter username and password:"'); header('HTTP/1.0 401 Unauthorized'); echo 'Please enter your Twitter username and password to view your followers.'; exit(); } $username = $_SERVER['PHP_AUTH_USER']; $password = $_SERVER['PHP_AUTH_PW']; The problem now is, I want to integrate it into a form, so far I have the following: <form action="logincheck.php" method="post" class="niceform" > <fieldset> <legend>Twitter Login:</legend> <dl> <dt><label for="email">Twitter Username:</label></dt> <dd><input type="text" name="username" id="username" size="32" maxlength="128" /></dd> </dl> <dl> <dt><label for="password">Password:</label></dt> <dd><input type="password" name="password" id="password" size="32" maxlength="32" /></dd> </dl> </fieldset> <fieldset class="action"> <input type="submit" name="submit" id="submit" value="Submit" /> I am sending it to logincheck.php, this is where I think I get stuck. I am not sure how to compare the form data with Twitter's login data. I was trying a similar if statement as I used in the first code (box that pops up before page loads), but I couldn't wrap my head around it. Thanks again guys!

  • Dynamic width of DIV (offsetWidth issue).

    - by Tom
    Hi all, I face issue with retrieving (via javascript) width of the div which content is changed (just before reading the widht via offsetWidth) in dynamic way (via changing innerHTML or using createTextNode). Here is some sample code: var con = document.getElementById('avContent'); //content div within page var temp = document.createElement('div');<br /> var text1 = document.createTextNode('CCCCC');<br /> temp.appendChild(text1);<br /> con.appendChild(temp);<br /> var length1 = temp.offsetWidth;<br /> var text2 = document.createTextNode('CCCCC33333333vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv');<br /> temp.removeChild(text1);<br /> temp.appendChild(text2);<br /> con.removeChild(temp);<br /> con.appendChild(temp); var length2 = temp.offsetWidth;<br /> The length1 and length2 do have the same width.. (the same result I get while using innerHTML instead of createTextNode). Looks like it's the same issue like described in following discussion: http://www.webdeveloper.com/forum/showthread.php?t=187716 Does anybody have answer (work around)? Thanks much for help in advance.
