• Drawbacks of WebFormsMVP?

  - by Tony_Henrich

  While ASP.NET MVC seems to be a viable technology praised by a lot of developers, I can't seem to find enough reasons to devote my energy and time for it. The main reason is that I don't find enough .NET jobs asking for it. Companies still use WebForms and it works just fine for them. I am not self employed where I get to choose the technology I like. I would rather use my time improve my skills in SilverLight, JQuery, Javascript, SQL, LINQ.. etc. Even Photoshop! So I got interested in webformsmvp.com. I get to still use WebForms and use better testing methods. Anyone who has experience with it can tell me what they didn't like about it?

• Get the full URI from the href property of a link

  - by Savageman

  Hello SO, I would like to have a confirmation on some point. My goal is to always get the same string (which is the URI in my case) while reading the href property from a link. Example: <a href="test.htm" /> with base_url = http://domain.name/ <a href="../test.htm" /> with base_url = http://domain.name/domain/ <a href="http://domain.name/test.htm" /> with base_url = any folder from http://domain.name/ I need to get http://domain.name/test.htm from the 3 situations above (or any other identical string). After some tests, it appears that my_a_dom_node.href always return the full-qualified URI, including the http://domaine.name, which should be okay for what I want. jQuery has a different behaviour and $(my_a_dom_node).attr('href') returns the content (text) that appears inside the HTML. So my trick is to use $(my_a_dom_node).get(0).href to get the full URI. The question is: can I rely on this?

• javascript removeChild() and appendChild() VS display=none and display=block|inline

  - by Kucebe

  I'm developing a web application that shows some controls and descriptions dinamically (I don't want to use jQuery or other libraries). At this moment i make appear and disappear controls using: element.setAttribute("style", "inline"); and element.setAttribute("style", "none"); but i'm thinking about using: element.appendChild(childRef); and element.removeChild(childRef); So, which one is the best solution in terms of system speed and elegance of the code? (and of course, are there better solution?)

• Lightbox for embeddable JavaScript widget? Like Feedback tabs for UserVoice/GetSatisfaction

  - by Eliot Sykes

  There are so many lightboxes to choose from, I'm looking for a very lightweight one to use in an embedded javascript widget that would be used on a number of different web sites. This would work in a similar way to the GetSatisfaction/UserVoice feedback tab. Here are the requirements for the lightbox: Very small javascript download (animation not needed) Self contained, not dependent on any libraries such as jquery, etc. Works in major browsers Lightbox displays HTML content from a given URL Close button (like GetSatisfaction or UserVoice) Dims background Avoids javascript namespace conflicts (or can easily be made to avoid them) CSS styling of lightbox does not interfere with site styling Have you used an existing lightbox scripts for this same purpose with similar requirements? Did you roll your own? Insights welcome! Thanks, Eliot

• Determining full XHR request URL on a Google Chrome XHR Breakpoint

  - by DanH

  I am initiating a jQuery ajax ($.ajax) post, within the Google Chrome browser. I have setup a XHR breakpoint in the "XHR Breakpoints" section of the "Scripts" tab within the Developer Tools. The criteria of the breakpoint is "get" ie. I want the debugger to break on all XHR requests which contain the word "get" in them (somePage.asmx/getListOfAnimals) is an example. The breakpoint is being correctly hit, however I am unable to determine what the exact URL that is being requested. I realize I can remove the breakpoint and see what URL is being requested from the "Network" tab, but I want to know this at the time the breakpoint is hit. I have tried stepping through the XHR request once it has been hit in Chrome, but I must be missing a Javascript object/property which contains the fully requested URL. Google Chrome has detected that the XHR requested URL contains "get" but how do I get to this URL from within the debug session before the request is made?

• How to order <script> tags vs. <style> tags in HTML markup for best results.

  - by Tchalvak

  I'm building up my site over at http://royronalds.com, and I'm trying to figure out what order of elements in the <head> makes most sense. Just to take from what I current have, I have: <head> <style> external stylesheet <meta> <title> <link> to favicon <script> for jQuery <script> main javascript for site <script> google analytics, asynchronous script. </head> Are there reasons to order these differently so that load times and other issues happen more smoothly, and if so, what would the ideal order be?

• MVC Pattern Clarification

  - by Amutha

  Just I started learning MVC pattern,ofcourse i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there) 1 ) MVC does not support server side events ,but supports client side events.if it supports client side events,i need html page with jQuery/Javascript (view),but most of the example i absorbed is to display the information(model) in view ,i did not see any client side event handling happens in view. 2) Except ViewState and controlState,MVC supports Sessions,Application State management,Cache management. 3) When request goes to MVC engine ,the routing module routes the request that is picked up by the controller.The controller in executes the appropriate action and return the appropriate view.

• Visual studio asp.net code behind file not showing errors

  - by Mahesh

  Hi, I am developing a web application in which I am suddenly facing an issue. I have a webpage which contains many controls, one of the control is JQuery color picker. Now, I am upgrading my system with telerik controls. As part of this process, I replaced textbox(txtcolor) with radcolorpicker with a different id(colorPicker). Suddenly, my code behind file is not throwing any errors like 'unable to find txtColor'. It is running successfully without build errors. But, when I open the page, system is throwing runtime exception(txtColor not found) which is correct. I tried to change other controls with asp.net controls, still the problem persists. So, I dont think it is anything to do with telerik. Could you please let me know how can fix this issue?? Thanks, Mahesh

• Create unordered list tree menu from data stored in an table with the adjacency list model...php

  - by Ronedog

  I need to create a tree menu of "nth" subcategories. I settled on using the adjacency list model for my table structure, because I won't be updating this table very much and this seemed the easiest to implement for my use. I want to style the output using "ul" and "li" tags...I already have a css and jquery solution to do the styling. My problem comes from pulling the data out of the database and using a recursive function via PHP to build the list ... the list is a concatenated string that gets parsed to build the tree. I'm really having a hard time getting the closing "ul" and "li" tags to line up just where they need to be. Is this the best way to do this? Are there other better ways using arrays or something like that to do this? Any examples you can point me to of "best practices" for building a list like this will be appreciated. Thanks.

• Using Ruby Hash instead of Rails ActiveRecord in Coffeescript / Morris.JS

  - by Vanessa L'olzorz

  I'm following the Railscast #223 that introduced Morris.JS. I generate a data set called @orders_yearly in my controller and in my view I have the following to try and render the graph: <%= content_tag :div, "", id: "orders_chart", data: {orders: @orders_yearly} %> Calling @orders_yearly.inspect shows it's just a simple hash: {2009=>1000, 2010=>2000, 2011=>4000, 2012=>100000} I'll need to modify the values for xkey and ykeys in coffeescript to work, but I'm not sure how to make it work with my data set: jQuery -> Morris.Line element: 'orders_chart' data: $('#orders_chart').data('orders') xkey: 'purchased_at' # <------------------ replace with what? ykeys: ['price'] # <---------------------- replace with what? labels: ['Price'] Anyone have any ideas? Thanks!

• ASP MVC View Content as JSON

  - by Craig

  I have a MVC app with quite a few Controller Actions that are called using Ajax (jQuery) and return partial views content which updates a part of the screen. But what I would rather do is return JSON something like this. return Json(new { Result = true, Message = "Item has been saved", Content = View("Partial") }); Where the HTML is just a property of the Json. What this means is I need to retrieve the HTML that is rendered by the View method. Is there any easy way to do this, a few examples I have seen are quite convoluted. Edit: This question was originally for ASP.NET MVC 1, but if version 2 makes it easier I would like to hear the answer.

• How do i handle jcupload and no flash?

  - by acidzombie24

  I am using http://www.jcupload.com/ (basic) to upload files. I am considering having a friend write a more custom version or to do magic with ajax; so the solution should be able to work without that. With jcupload i include css, a script and write <div id="jcupload_content"></div> in my html and i am done. Problem is, with no flash i get an object box. Instead i would like is an iframe or a html form to upload the file. How do i do this? Should i detect flash from javascript and overload the div myself if no flash is available? How do i detect if flash is available? with jquery i know i can write something like $('#jcupload_content').innerHtml = blah; How do i handle the flash part?

• Do Any Client-Side JavaScript Frameworks Integrate Well With Node.js+Express.js+socket.io.js?

  - by Tom D

  I'm building an webapp using Node.js+Express.js+socket.io.js on the backend. Do any of the popular front-end frameworks (Agility, Angular, Backbone, Closure, Dojo, Ember, GWT, jQuery, Knockback, Knockout, Spine, YUI, etc) integrate well with this backend for "real-time" applications? I want my application to have a very "real-time" feel. Specifically, when a user submits a form I want the information to be sent using web sockets to the backend for validation and (if validation passes) to be updated in the database. Then, the server-side will use web sockets to send a confirmation that the data was saved or some list of errors. I will use the server's response to update the page using JavaScript. I know all this can be done with any of the listed frameworks. I'm interested in features of particular frameworks that will help the framework integrate better with the Node-based backend than the other frameworks.

• Javascript string to Date conversion - simple?

  - by Mark White

  Hi all, Yesterday I managed to solve this, then lost a day's work due to the death of a HD. Now I cannot remember what I did to fix it, but I know it can be done. Input: string date in the format 'm/d/yy', eg '12/25/10', or '4/1/10' (1st April) Output - Date object I'm working with date.js and date.format.js so have Date.fromString() and Date.format() avaiable. But trying multiple combinations is not giving me what I need. IF the date were 'mm/dd/yy' then it's simple. But I'm using jquery.datepicker.js which outputs in 'm/d/yy' and I don't want to change this much I know this conversion can be done. After a 22 hour day... I need help. Thanks. Mark...

• Using SWFObject, the flash moves 1 pixel to the right on Firefox

  - by jeffkee

  Please check this page: http://islandhideaway.weebly.com/ For whatever reason, the flash slideshow moves over 1 pixel when opened in Firefox on my Mac. All other browsers render it fine, but only on Firefox it leaves a 1 pixel white gap on the left! I am using the most recent version of SWFObject. This unfortunately is a garbage Weebly site and I cannot use jQuery in the system so I can't do a real gallery... so let's save the whole "don't use Flash for that" pep talk. It's a favour for a friend and I am already aware of better ways to do it. :)

• select time (HH:MM:SS.mmm) in javascript

  - by acidzombie24

  I would like the user to select the time in javascript and to avoid selecting the wrong time. How should i do it? Is there some kind of javascript or jquery widget? or should i show the format and allow users to write it in (and i guess check it with regex)? i think these should be valid 1 (1s) 1:5 (1m 5s) 1.5 (1s, 500 milliseconds. not to be confused by the above) 1:2:02 (1h, 2m, 2 seconds) 1:2:2 (1h, 2m, 2 seconds) 1:2:20 (1h, 2m, 20 seconds) I dont want the user to be confused. How can i avoid this?

• Cross Domain Scripting Issues & JSONP

  - by DaveDev

  Our Client requires that we supply Widgits for their site. They want to link to us to get Html & the jQuery required to manipulate the Html and do asynchronous requests. I understand that there are cross-domain security limitations that would prevent this from being a possibility, but that some of those limitations are aleviated by using JSONP as the data transfer format. I'm finding it difficult in finding an explanation of what's possible in the context of what I'm trying to achieve. Could somebody please fill me in?

• dojo datagrid will make the page "jump" when sorting is changed

  - by Select0r

  Hi, I have a Dojo Datagrid in one of my pages (which contains more content) and the following problem occurs: As soon as I click on a column header to change the sorting, the page will jump up as if I clicked on some HTML-anchor. Funny enough, the page jump will make the grid show only the first two rows after it jumped, instead of (e.g.) have the grid start at the top of the page after the jump, which is the expected behaviour if an anchor is used. The problem occurs in different browsers (tested: Firefox 3.6, Opera 10, IE6), so I guess it might be a Dojo-problem/-bug. Any ideas to make this annoying behaviour stop? Greetings, Select0r PS: this seems to describe a similar problem, only for JQuery (and unfortunately without a solution, too)

• jqueryui themeroller

  - by cf_PhillipSenn

  I'm learning about the Framework Icons in jQuery UI. <span class="ui-icon ui-icon-circle-minus"></span> produces an icon of a minus sign inside a circle. Using the ThemeRoller Firefox Bookmarklet, I was able to change the color of the icon to red (to make it look like a delete button). Q: How can I make one jQueryUI icon be red and another one another color? <span class="ui-icon ui-icon-circle-plus"></span> I'd like to make this one green.

• How to store user preferences? Cookie becomes bigger..

  - by ari

  My application (Asp.Net MVC) has great interaction with the user interface (jQuery/js). For example, setting various searches charts, moving the gadgets on the screen and more .. I of course want to keep all data for each user. So that data will be available from any page in the Dumaine and the user will accepts his preferences. Now I keep all data in a cookie because it did not seem logical asynchronous access to the server each time the user changes something and thet happens a lot.When the user logout from the application I save the cookie to the database. The problem is the cookie becomes very large. The thought that this huge cookie is attached to each server request makes me feel that my attitude is wrong. Another problem cookies have size limit. It varies from your browser but I definitely have been close to the border - my cookie easily become 4kb Is there another solution?
