• Coping with weak typing

  - by John Leonard

  I'm a front end Flex developer peeking over the wall at html. One of the things I have a hard time with is weak typing in Javascript. I know many developers say they prefer it. How do I stop worrying and learn to love the weak typing? Are there best practices for variable naming that help make var types human readable? Another thing I have trouble with is getting by without my trusted compiler errors and warnings. I'm getting along with firebug. Is there anything else I should have in my toolkit?

• XML DOM Manipuation

  - by kunalsawlani

  Hi, I am new to XML and have been trying some simple examples and they work fine. I want to do something like the following, but I am not able to figure out how to go about doing this. I have a HTML web page, where the user types in some data in an input field. I want to take that data, parse it to create an XML string, and the apply XSLT transformation to it, and display the result back on the page. All this needs to be done on the client browser, with JavaScript. If some one could point out the steps or the general procedure to go about doing this, it would be great. I have been looking over the net, but the information is so vast, that I have not been able to locate exactly what I need. Thanks

• Windows desktop gadget RSS Feed colour coding items

  - by padjo

  I have a desktop gadget that pulls RSS Feeds from a website. The Feed contains information about issues - ie. Priority, Time, Description. The Feed items are displayed on the desktop - however I need to colour code them according to their priority ie 1 = red etc. using the substr function - is there a better way to do this using JavaScript / HTML? At the moment I've hacked together this - but is there a more elegant solution? if (feed.item.description.substr(10,1) == "1") { document.write "<a href colour="red"" + item + ">"; else if (feed.item.description.substr(10,1) == "2") { document.write "<a href colour="yellow"" + item + ">"; else { document.write "<a href colour="green"" + item + ">";

• iPhone Scroll images horizontally like in AppStore

  - by schaechtele

  Hi there, I was wondering if it's possible to create a HTML div container with some CSS magic that shows a horizontal scrollbar like the one with the screenshots on the iTunes preview on the web. I want this to work in Safari on the iPhone. e.g. http://itunes.apple.com/app/super-monkey-ball/id281966695?mt=8 I would like to use that to display thumbnails in an UIWebView on iPhone. I experimented with the overflow css property but didn't get it to work. Thanks for your replies.

• urllib alternative for iPhone

  - by Pr301

  hi, I am trying to create an iPhone application which in some point connects to the internet, fills an on-line form, fetches the resulting website, parses it and returns a string to the user. I want all this process to happen in the background. I know how to do this kind of things with python and urllib but in objc I can't find an alternative, from on-line search I found either sites that explain how to use webkit to retrieve webpages (I suppose this is for displaying them to the user) or how to parse an existing HTML file or string. Since I want the file to be retrieved from the internet and the whole process should be running in the background, neither of these solutions covers my needs.

• Very long tree control inside a <frame>

  - by ryancerium

  I have an tree control inside of a frame. It's quite tall, around 2000 pixels. Right now, we use the frame's scroll bars, which is mostly good. Unfortunately, when you select an item near the bottom of the list, the page reloads and the view goes back to the top of the list. I tried calling the tree control's ScrollNodeIntoView() function, but since we're not using the tree's scroll bars, it just thinks that it's displaying the full 2000 pixels and the control doesn't have its own scroll bar. I'm not much of an HTML guru, so I have two ideas, neither of which I know how to do. 1) Tell the frame to not to let the tree render all 2000 pixels and instead stay inside the viewable area. 2) Tell the tree to not render all 2000 pixels and instead stay within the viewable area. Setting the CSS height property on the within the frame doesn't do anything. Thanks.

• Livevalidation: only validate when default value is changed

  - by usr122212

  Hello there! I am validating my html form with livevalidation and everything works great except for one feature. I have a input field with a default value age, I only want the livevalidation to validate when it says something other than "age". so maybe the user will type in 20 then the validation will fire checking its things but if left as "age" it won't check it all. But as of now, it just checks everything with a validation script and this is a problem for me as I have lots of fields in my form and some of them are optional so when I hit submit, the livevalidation checks the age field as well even if the user didnt touch it to begin with. Would this be possible with livevalidation ? Thanks for the help.

• jQuery Click event on object added with JavaScript not working.

  - by Hultner

  I'm work on a quiz for school but I've bumped into a problem. I got a javascript file for custom radio buttons (CUSTOM FORM ELEMNTS by Ryan Fait if it's helping). The script hides the input buttons and adds custom styled spans instead. Now what I want, when I click one of these JavaScript added spans I want to remove disabled for a button called "Next Question" which when pressed takes you to the next question. The reason for this is that I don't want people to accidently got to the next question without choosing a answer. The problem is when I press the added spans nothing happens but when I press another identical span which I have added in the html it works just as intended. The span got the class radio which is the class I'm looking for in the jQuery. Here's the test page with the error on: http://hultner.se/graphicsquiz/livetest/livetest.php Short: Can't get jQuery .click() functions to work with spans added using JavaScript earlier in the document.

• Fading transition slideshow

  - by Simon Carlson

  I've got a JavaScript that produces a slideshow. It loads the pictures before starting the actual slideshow. Code below. var image1=new Image() image1.src="filename1.jpg" var image2=new Image() image2.src="filename2.jpg" var image3=new Image() image3.src="filename3.jpg" var step=1 function slideit(){ if (!document.images) return document.images.slide.src=eval("image"+step+".src") if (step<3) step++ else step=1 setTimeout("slideit()",1000) } And this is the required HTML for it to work: <img src="filename1.jpg" name="slide" /> Now, if I want to have fading transitions instead of just having new pictures popping up, how do I approach this? By fading I mean either have the old picture fade out, the new fade in or possibly and most likely both fade in/out. Can this be achieved with pure JavaScript and no jQuery or Ajax?

• Static footer, with attached and scaling overlap

  - by DavidYell

  I have been asked by a client to create a site where the content area overlaps the footer. However they also want the footer to be attached to the bottom of the viewport, which I've done, but it seems that I can't find a good way to vertically stretch the content to maintain the overlap should the browser be resized. I've created a diagram to help explain, http://www.squaresphere.co.uk/images/footer-diagram.png So ideally I need a way of calculating the height of the content and stretching the content div if content_length viewport.height, but keep a min-height if content_length < viewport.height A solution using html+css would be fantastic, but I'm starting to think that I'm going to have to do some funky jQuery onviewportresize or something Any suggestions would be awesome, thanks!

• How do you have grayed out text in a textfield that dissapears when the user clicks on it

  - by John Smith

  In HTML & JS, how do you make a textfield that has grayed out text telling the user what the field is for that goes away when the user clicks on the field? For example, in firefox the search field in the top right hand side says which search engine it uses when there's nothing entered, then once you click it's an empty textfield, but if you leave it blank and remove focus from the textfield then the grayed out text is back again. Is there a name for this behavior? Also, is it possible to do in pure css without the use of js to do the on focus / on blur events?

• Best way to position a two part background in CSS?

  - by Kevin Z

  Hey All! I have a weird background I am trying to figure out the best way to style it. So, there are two parts to the background image, the top part which has a unique horizontal and vertical design (its about 1024x700) then a bottom section that has a unique style horizontally, but can be repeated vertically . (1024 x 1) Right now I have the top section being a background image for the header, the problem is that it screws me up for styling all of the page content because it is so big! What would be the best way to code a two piece background like that in HTML and CSS? Thanks! Kevin

• Styling the selection color of an input type=text, possible?

  - by Tommy

  Having an input <input type="text" id="myTest" value="bla bla bla"/> and doing this (using jQuery) $('#myTest').select(); causes "bla bla bla" to be selected with default dark blue selection color. Now, is there any way I can change this color using css? css3 can change selection using for instance ::-moz-selection { background: #ffb7b7; } but this only works on text in other elements, not in html inputs. Any ideas? /T

• Extract anything that looks like links from large amount of data in python

  - by Riz

  Hi, I have around 5 GB of html data which I want to process to find links to a set of websites and perform some additional filtering. Right now I use simple regexp for each site and iterate over them, searching for matches. In my case links can be outside of "a" tags and be not well formed in many ways(like "\n" in the middle of link) so I try to grab as much "links" as I can and check them later in other scripts(so no BeatifulSoup\lxml\etc). The problem is that my script is pretty slow, so I am thinking about any ways to speed it up. I am writing a set of test to check different approaches, but hope to get some advices :) Right now I am thinking about getting all links without filtering first(maybe using C module or standalone app, which doesn't use regexp but simple search to get start and end of every link) and then using regexp to match ones I need.
