  • Adding characters to string (input field)

    - by Zaps
    Hi, I have a text box where the value the result of a calculation carried out in jQuery. What I would like to do, using jQuery, is to display brackets around the number in the text box if the number is negative. The number may be used again later so I would then have to remove the brackets so further calculations could be carried out. Any ideas as to how I could implement this? Thanks Zaps

  • Autopostback select lists in ASP.NET MVC using jQuery

    - by rajbk
    This tiny snippet of code show you how to have your select lists autopostback its containing form when the selected value changes. When the DOM is fully loaded, we get all select nodes that have an attribute of “data-autopostback” with a value of “true”. We wire up the “change” JavaScript event to all these select nodes. This event is fired as soon as the user changes their selection with the mouse.  When the event is fired, we find the closest form tag for the select node that raised the event and submit the form. $(document).ready(function () { $("select:[data-autopostback=true]").change(function () { $(this).closest("form").submit(); }); }); A select tag with autopostback enabled will look like this <select id="selCategory" name="Category" data-autopostback="true"> <option value='1'>Electronics</option> <option value='2'>Books</option> </select> The reason I am using “data-" suffix in the attribute is to be HTML5 Compliant. A custom data attribute is an attribute in no namespace whose name starts with the string "data-", has at least one character after the hyphen, is XML-compatible, and contains no characters in the range U+0041 to U+005A (LATIN CAPITAL LETTER A to LATIN CAPITAL LETTER Z). The snippet can be used with any HTML page.

  • Accessing Server-Side Data from Client Script: Using WCF Services with jQuery and the ASP.NET Ajax Library

    Today's websites commonly exchange information between the browser and the web server using Ajax techniques - the browser executes JavaScript code typically in response to the page loading or some user action. This JavaScript makes an asynchronous HTTP request to the server. which then processes the request and, perhaps, returns data that the browser can then seamlessly integrate into the web page. Two earlier articles - Accessing JSON Data From an ASP.NET Page Using jQuery and Using Ajax Web Services, Script References, and jQuery, looked at using both jQuery and the ASP.NET Ajax Library on the browser to initiate an Ajax request and both ASP.NET pages and Ajax Web Services as the entities on the web server responsible for servicing such Ajax requests. This article continues our examination of techniques for implementing lightweight Ajax scenarios in an ASP.NET website. Specifically, it examines how to use the Windows Communication Foundation, or WCF, to serve data from the web server and how to use both the ASP.NET Ajax Library and jQuery to consume such services from the client-side.

  • jQuery: Novice to Ninja

  • Codeigniter + JQuery + Processing.js to replace a Delphi App

    - by Peter Turner
    So, I've got a mandate to make our aged trillion lined Delphi app web based and it needs to make heavy use of the <canvas> element (HTML5 compatibility doesn't seem to be a big issue since we can just make our clients use a compatible browser the way we'd make them use a compatible version of Windows in the win32 environment). The Delphi app in question is almost completely database driven and will still pretty much continue to be developed as the main product. What I am tasked with is pretty much recreating a scaled down version of the program that performs the major functions of the whole program. I couldn't find any frameworks that simulate windows forms using the canvas element, I'm assuming this is probably by design since it is easier just to use HTML, well, be that as it may, I still think it would be cool to have a few of my cool controls on the web (TRichView and TVirtualTree, etc...) So my question is, to anyone who has tried this before, A.) What can we use for an IDE to code this web app (I just use emacs, but no one else in my company does)? B.) Is it a good idea to mix PHP and Processing.JS? It seems like I'm using a lot of AJAX to get anything to happen. 3 calls just for one dialog box to pop up, Loads the HTML for the dialog, Loads the XML to populate the database info on the form Loads the processing.js PJS file which draws the database info to the canvas. Is three a lot, do people usually combine all their gets into one?

  • PHP+AJAX with MySQL - Query every 2 seconds, too many in TIME_WAIT

    - by Ryan
    I have a basic HTML file, using jQuery's ajax, that is connecting to my polling.php script every 2 seconds. The polling.php simply connections to mysql, checks for ID's newer than my hidden, stored current ID, and then echo's if there is anything new. Since the javascript is connecting every 2 seconds, I am getting thousands of connections in TIME_WAIT, just for my client. This is because my script is re-connecting to MySQL over and over again. I have tried mysql_pconnect but it didn't help any. Is there any way I can get PHP to open 1 connection, and continue to query using it? Instead of reconnecting every single time and making all these TIME_WAIT connections. Unsure what to do here to make this work properly.

  • Using JQuery to set create a flexible 3 column layout with Divs

    - by Chris Hammond
    This evening I was working on creating a Full Width skin for http://www.sccaforums.com/ , the current skin is at a fixed width, which doesn’t work very well for an active Forum when you have a browser with a high resolution. (The site runs on DotNetNuke , so this post will feature examples for DotNetNuke, but the code is applicable to any HTML pages) Basically I wanted a three column layout, and depending on if there was content in the Left and Right columns, I wanted them to not display at all,...(read more)

  • Disable pasting in a textbox using jQuery

    - by Michel Grootjans
    I had fun writing this one My current client asked me to allow users to paste text into textboxes/textareas, but that the pasted text should be cleaned from '<...>' tags. Here's what we came up with: $(":input").bind('paste', function(e) { var el = $(this); setTimeout(function() { var text = $(el).val(); $(el).val(text.replace(/<(.*?)>/gi, '')); }, 100); }) ; This is so simple, I'm amazed. The first part just binds a function to the paste operation applied to any input  declared on the page. $(":input").bind('paste', function(e) {...}); In the first line, I just capture the element. Then wait for 100ms setTimeout(function() {....}, 100); then get the actual value from the textbox, and replace it with a regular expression that basically means replace everything that looks like '<{0}>' with ''. gi at the end are regex arguments in javascript. /<(.*?)>/gi

  • Which is preferable? To know jQuery well, or to know JavaScript well? [closed]

    - by Marwan
    I'm quite familiar with using jQuery, but I've come to feel like a bit of a dummy using it, as my knowledge of JavaScript itself is rather poor. So I'm considering abandoning jQuery and spending time working in straight JS... perhaps even creating my own framework as a learning experience. Does this make sense though? Is there any real point to obtaining more than a passing knowledge of JavaScript when jQuery allows me to accomplish so much, so quickly?
