• Get a CSS value from external style sheet with Javascript/jQuery

  - by Acorn

  Is it possible to get a value from the external CSS of a page if the element that the style refers to has not been generated yet? (the element is to be generated dynamically). The jQuery method I've seen is $('element').css('property','value');, but this relies on element being on the page. Is there a way of finding out what the property is set to within the CSS rather than the computed style of an element? Will I have to do something ugly like add a hidden copy of the element to my page so that I can access its style attributes?

• How to get a Javascript routine to NOT act if it's in a text box?

  - by talkingnews

  I've got a simple page, and in that page runs a simple jquery keypress routine to catch clicks of the numbers 1 to 9 (has to be that to pass RNIB accessibility test). And in that page is a form, which can have numbers entered as part of a postcode. http://find.talking-newspapers.co.uk/result.php?addressInput=kingston Scroll to the bottom, try typing 8 or 9 for example. The text is entered, but it also acts on the keypress. Expected, but not good. I'm aware of various things like document.getElementById, but I can't figure out how to put these together to ensure that while the cursor is in the text input box, it doesn't act out the keypress catcher.

• Keeping asp.net mvc site IIS6 always ready to accept requests

  - by Andrew Florko

  I have asp.net mvc intranet site that is deployed to IIS6. Site is used rarely so app pool tends to shutdown. When user click the page for the very first time 5-10 seconds are passed till page appears (app pool started and site is compiled). Situation repeats for the next page and so on. AFAIK IIS7 has option to disable App pool shutdown but IIS6 lacks it. Nowadays i have special utility that pings site periodically (10 pages) in order to determine if pages are available and keeps site always ready for users this way. Is it normal or may be I've missed something in IIS6 configuration? Do you use such pinger apps in production to notify support/admins if site is not available? Thank you in advance!

• How to restore Google "Cached" links?

  - by Steven Penny

  On Google search, "Cached" links are available, which take you to a version of the page saved on Google servers. These links are quite useful if the source page is temporarily down or otherwise. Back in July 2011 Google moved these links inside of an "Instant Preview" box. Many people from this thread and others either simply cannot find the new links or prefer the old location. Edit To be clear, the question is how to restore the links to the old location.

• wordpress image showing up multiple times

  - by JCHASE11

  I am writing a wordpress theme, and have run into a fairly basic problem. By default, when you inset an image into the post, it displays that image at the size you specify, on both the homepage and the single post. I would like to have different sized images, displaying a thumbnail on the homepage, and a full sized image when you click through to the post. I am using wordpress 2.9's new thumbnail feature, which has created great thumbnails for the homepage. But now, I am stuck with a nice thumbnail next to a large photo (on the index/home page). On the single page, it is displaying correctly with just the large picture. Basically, I need to know how to tell wordpress to only display the large post image on the single page, not on the index. Also: I have used the timthumb script, but I think the answer is far more basic then needing plugins or scripts Thanks!

• Programmatic Website Screen Shots

  - by Ian

  I'm checking into the available methods for programmatically taking screenshots of an arbitrary website. For example, Facebook: http://clicktoverify.truste.com/pvr.php?page=validate&url=www.facebook.com&sealid=102 Salesforce.com: http://clicktoverify.truste.com/pvr.php?page=validate&companyName=Salesforce.com,%20Inc.&sealid=102&internal=true On that page you'll see they have a screenshot of the referenced site. What are my options for getting these kinds of screenshots in an automated fashion? I'm primarily working with PHP, but am open to all suggestions. Thanks!

• Set a class for an element in a PHP include()

  - by paracaudex

  I have an identical horizontal menu at the top of all of my pages, which I add using a PHP include() statement. In my stylesheet I want to have a class where if the user is on a particular page, the menu item corresponding to that page will have a different color. So, more or less: #dropdown { background-color:blue; } #dropdown .active { background-color:green; } But, since the menu comes from the PHP include, it's always the same. How can I write some PHP or JavaScript that adds class="active" to the appropriate menu item for each page?

• Nginx logic (if cookie set, redirect here...) Is it possible?

  - by Matthew Steiner

  So, I have a pretty basic need, but I can't figure out if it's even possible, much less how to do it. I have a main page that anyone can see. Most of the rest of the application can be seen only if logged in (hence, a "set cookie"). So I was thinking, as long as they don't have a cookie set, they can just see a cached version of nginx. I can get it caching with this: proxy_cache STATIC; proxy_cache_valid 200 1d; proxy_cache_use_stale error timeout invalid_header updating http_500 http_502 http_503 http_504; And it helps a ton. (instead of 15 requests per second it gets over 1000). Now I just need some sort of "server logic" to say only serve the cached page if they have no cookie, otherwise, load the dynamic page (which will automatically redirect them into the app). Any ideas?

• asp.net mvc script and style references

  - by tom

  I'm trying to include script and style references that will not break on deployment, however I can not even get the references to work locally. I have tried using Url.Content() and MVCContrib's <%=Html.ScriptInclude("")%>. My scripts are in a Scripts folder on the root of the site; my styles are in the usual Content/css/ folder. The scripts render like this: <script type="text/javascript" src="/Scripts/MicrosoftAjax.debug.js" ></script> This will not work in a view page in the Views folder. What am I doing wrong and what is the best way to handle this? I would have thought Url.Content() would at least work for styles but used in my master page, the link rendered <link href="/Content/css/Site.css rel="stylesheet" type="text/css" /> This does not work, because the Master Page is in a Shared folder, so what is really the way forward with this?

• Printing All Entries in A PHP Table

  - by mgunawan

  I'm trying to insert a php excerpt with SQL (I understand this is outdated, but am trying to grasp the syntax first) into my HTML page, and I've got the following table: ID Name Element1 Element2 0 John John's 1st John's 2nd 1 Bill Bill's 1st Bill's 2nd 2 Steve Steven's 1st Steve's 2nd I'm trying to get the for loop that will essentially print out the following in my html page Name: Name where ID=0 Element1: Element1 where ID=0 Element2: Element2 where ID=0 Name: Name where ID=1 Element1: Element1 where ID=1 Element2: Element2 where ID=1 and so forth. Basically, I am trying to make this process automated so that whenever a new record is added into the table, the HTML page will automatically update with a new "profile". Thank you for your help!

• Modifying a global variable from <a href>

  - by a_m0d

  I have created some code to popup a confirm dialog if a user tries to leave a page without saving their changes. However, I don't want the confirmation dialog to popup if the user has clicked the "Save" button. I have some code at the top of my file which looks like this: var confirmClose = false; window.onbeforeunload = function(evt) { if (confirmClose == true) { message = "There are unsaved changes on this page. Are you sure you wish to leave?"; if (typeof evt == 'undefined') { evt = window.event; } if (evt) { evt.returnValue = message; } return message; } } Further down on the page I have a link which looks like this: <a href="javascript:confirmClose=false;$('#stockForm').submit()" title="Save" class="button positive" id="stockFormSubmit">Save</a> However, this doesn't seem to work - it doesn't seem to change the value of confirmClose, and changing it to window.confirmClose didn't help either. What am I doing wrong here?

• Online Advetisement/Banner Management System

  - by Sumesh Joshi

  I am developing site for online advertisements where sellers and buyers can come and sell/buy advertisements. Just need to develop detailed statistics like click counts, from which page clicks are coming (one advertisement can be placed on many pages), from which position (top, right, left ...) click are coming (one advertisement can be placed in different position on single page) etc. I seen that most of the advertisement on popular websites has following format: http://ads.stackoverflow.com/a.aspx?Task=Click&ZoneID=3&CampaignID=838&AdvertiserID=50&BannerID=1335&SiteID=1&RandomNumber=1463177307&Keywords=c%23%2c.net%2ccollections%2cdictionary%2chashtable It has many parameters like ZoneID, CampaignID, AdvertiserID, BannerID, SiteID, RandomNumber, adid, adcrid, obid, obtid and way. I can use one advertisement (adid) in multiple pages. But can't figure out the way to distinguish between from which pages clicks are coming. How can I use such parameters to generate statistics which tell me the page from which clicks are coming?

• Intercepting static and dynamic links using javascript

  - by soren.qvist

  Hi, I'm currently developing an ajax application and I'm looking for a feature that lets me intercept all static and dynamic links using javascript. The links look like these: <a href="link1/">link 1</a> <a href="link2/">link 2</a> etc. I then want the browser to redirect to: current.page/#link1/ rather than current.page/link1/. I'm using jQuery, so the live() function is an option, however using that as a solution just seems rather sluggish to me(am I hysterical?). If there is a way to intercept ALL links on a page, maybe through detecting a change in the address, that would greatly help. I've tried a few plugins for jQuery (jQuery address & SWFaddress) but they only seem to have event handlers that respond to changes in anchor tags in the address. Any ideas? thanks for your time

• Writing a PHP web crawler using cron

  - by Horse

  Hi all I have written myself a web crawler using simplehtmldom, and have got the crawl process working quite nicely. It crawls the start page, adds all links into a database table, sets a session pointer, and meta refreshes the page to carry onto the next page. That keeps going until it runs out of links That works fine however obviously the crawl time for larger websites is pretty tedious. I wanted to be able to speed things up a bit though, and possibly make it a cron job. Any ideas on making it as quick and efficient as possible other than setting the memory limit / execution time higher?

• JQuery delegate what may cause it to not function

  - by Jafin

  I have a webpage using jquery 1.42 The following 2 segments of code live in my page. $('body').delegate('h2', 'click', function() { $(this).after("<p>delegate paragraph!<\/p>"); }); $('body h2').live('click', function() { $(this).after("<p>live paragraph!<\/p>"); }); The live method always works, yet the delegate doesn't fire at all. If I create a trivial page with simple html <body><h2>blah</h2></body> both approaches work. So I'm assuming there is something else going on in my page. With firebug I am seeing no javascript errors, no html errors. and breakpoints on the delegate method definately do not get hit. What else might be the cause of delegate not triggering?

• Smart pagination algorithm

  - by silvertab

  I'm looking for an example algorithm of smart pagination. By smart, what I mean is that I only want to show, for example, 2 adjacent pages to the current page, so instead of ending up with a ridiculously long page list, I truncate it. Here's a quick example to make it clearer... this is what I have now: Pages: 1 2 3 4 [5] 6 7 8 9 10 11 This is what I want to end up with: Pages: ... 3 4 [5] 6 7 ... (In this example, I'm only showing 2 adjacent pages to the current page) I'm implementing it in PHP/Mysql, and the "basic" pagination (no trucating) is already coded, I'm just looking for an example to optimize it... It can be an example in any language, as long as it gives me an idea as to how to implement it...

• ActiveRecordStore InvalidAuthenticityToken

  - by Andy

  I have recently been using cookie store and I want to transition to active record store. However I keep getting an invalid authenticity token. After deleting my cookies, I was able to access the page just fine, but I don't want all my users to come to my page, get a huge error and then figure out that I want them to delete their cookies. So I made a function called delete cookies: after_filter :delete_cookie def delete_cookie puts "deleting cookies" cookies.to_hash.each_pair do |k, v| puts k cookies.delete(k) end end In application controller, but it doesn't seem to be working correctly. I still see my cookie after visiting any page. I feel like there really should be a better solution but I can't seem to find any so far. Any hints?

• Calling gwt static method from parent of iframe

  - by Richard Wallis

  I'd like to know how to call a GWT static method from the parent of the iframe in which the gwt module is loaded. As a simple example suppose I have the following gwt class: public class Simple { public static void showWindow() { Window.alert("Hello from the iframe"); } } I create an html host page called "iFrameHost.html" that can run the function above. Then in an unrelated GWT module on a different page I call: Frame iFrame = new Frame("iFrameHost.html"); RootPanel.get().add(iFrame); How do I now call the showWindow() method from the parent page?

• How to read back and print text with newlines from a Python (Django) string with HTML?

  - by user1801486

  If someone types in a phrase, such as: I see you driving round town with the girl I love, and I’m like: haiku. (no blank lines between each line, but the text is written on three separate lines) into a text box on a web page, and then presses a button which is then stored in a database via Django, and that string is read back and printed on a page, how can I get it to print on an HTML page with the newlines still in the text? So instead of it being printed back as: I see you driving round town with the girl I love, and I’m like: haiku. It would print as: I see you driving round town with the girl I love, and I’m like: haiku. I know that if I use: (textarea)soAndSo.body(/textarea), this preserves the newlines that were in the file when the user typed it up originally. How can I get this same effect, but without having to use textarea boxes?
