  • Alternative to Page_Load in ASP.NET (and a good WTF story)

    - by Jason
    Woo, I have a doozy of a problem (might even be one for the Daily WTF) and I'm hoping there's a solution. (My apologies for the long post...) I have been working on a website that I inherited about a month ago. One of the parts I have been working on is fixing one of the controls (essentially a dynamic header bar) so that it displays additional information as requested by my users. As part of doing this project, I created a Site.master file so that I wouldn't have to recode the header bar into every single page. When I first started doing this, it seemingly worked very well. All the pages I had developed looked great and the bar updated as it should displaying the information as it should. Well, when I dropped the Site.master (and this control) into older site pages (ones I did not specifically develop) I noticed that it looked bad on some of them, but not all of them. When I say it looked bad, basically, the control would left-align itself to the page rather than center as it should. I spent a couple hours debugging to no avail - CSS looked correct, the HTML appeared to be okay, I didn't see anything in the Javascript (although, I did miss something as I'll point out in a second), and even the old code looked correct (to the best that it could - it's not very well written). Another coworker took a look at the site and couldn't find anything at first, either. It wasn't until I just thought to look at the rendered source code of the page (I had been working in the developer view up to this point in IE8) that it became clear what was wrong. The original developer performs searches on many of the pages. To accomplish this, he queries the database for ALL the data and then loads them into Javascript arrays within the page so he can get access to them. This in itself is a huge problem because we're talking about thousands of items, and it obviously isn't scalable (and, yes, the site is slow). However, it finally clicked what was screwing up the Site.master - when he loads the data into the Javascript arrays, he writes out the data to the HTML upon Page_Load using numerous Response.Write(string) calls. The WTF (and what was messing me up) is that he inserts the Javascript before the DOCTYPE causing IE to go into quirks mode! So, because I need to at least get this release out (I'll fix the real problem later), I was wondering: is there a way I can force this Javascript to be inserted elsewhere into the HTML—after the DOCTYPE at the very least? Right now, all the Response.Write() calls are being done in the Page_Load method. I just need them to be inserted later.

  • CDI SessionScoped Bean results in two instances in same session

    - by Ryan
    I've got two instances of a SessionScoped CDI bean for the same session. I was under the impression that there would be one instance generated for me by CDI, but it generated two. Am I misunderstanding how CDI works, or did I find a bug? Here is the bean code: package org.mycompany.myproject.session; import java.io.Serializable; import javax.enterprise.context.SessionScoped; import javax.faces.context.FacesContext; import javax.inject.Named; import javax.servlet.http.HttpSession; @Named @SessionScoped public class MyBean implements Serializable { private String myField = null; public MyBean() { System.out.println("MyBean constructor called"); FacesContext fc = FacesContext.getCurrentInstance(); HttpSession session = (HttpSession)fc.getExternalContext().getSession(false); String sessionId = session.getId(); System.out.println("Session ID: " + sessionId); } public String getMyField() { return myField; } public void setMyField(String myField) { this.myField = myField; } } Here is the Facelet code: <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <f:view contentType="text/html" encoding="UTF-8"> <h:head> <title>Test</title> </h:head> <h:body> <h:form id="form"> <h:inputText value="#{myBean.myField}"/> <h:commandButton value="Submit"/> </h:form> </h:body> </f:view> </html> Here is the output from deployment and navigating to page: INFO: Loading application org.mycompany_myproject_war_1.0-SNAPSHOT at /myproject INFO: org.mycompany_myproject_war_1.0-SNAPSHOT was successfully deployed in 8,237 milliseconds.

  • Precise explanation of JavaScript <-> DOM circular reference issue

    - by Joey Adams
    One of the touted advantages of jQuery.data versus raw expando properties (arbitrary attributes you can assign to DOM nodes) is that jQuery.data is "safe from circular references and therefore free from memory leaks". An article from Google titled "Optimizing JavaScript code" goes into more detail: The most common memory leaks for web applications involve circular references between the JavaScript script engine and the browsers' C++ objects' implementing the DOM (e.g. between the JavaScript script engine and Internet Explorer's COM infrastructure, or between the JavaScript engine and Firefox XPCOM infrastructure). It lists two examples of circular reference patterns: DOM element → event handler → closure scope → DOM DOM element → via expando → intermediary object → DOM element However, if a reference cycle between a DOM node and a JavaScript object produces a memory leak, doesn't this mean that any non-trivial event handler (e.g. onclick) will produce such a leak? I don't see how it's even possible for an event handler to avoid a reference cycle, because the way I see it: The DOM element references the event handler. The event handler references the DOM (either directly or indirectly). In any case, it's almost impossible to avoid referencing window in any interesting event handler, short of writing a setInterval loop that reads actions from a global queue. Can someone provide a precise explanation of the JavaScript ↔ DOM circular reference problem? Things I'd like clarified: What browsers are effected? A comment in the jQuery source specifically mentions IE6-7, but the Google article suggests Firefox is also affected. Are expando properties and event handlers somehow different concerning memory leaks? Or are both of these code snippets susceptible to the same kind of memory leak? // Create an expando that references to its own element. var elem = document.getElementById('foo'); elem.myself = elem; // Create an event handler that references its own element. var elem = document.getElementById('foo'); elem.onclick = function() { elem.style.display = 'none'; }; If a page leaks memory due to a circular reference, does the leak persist until the entire browser application is closed, or is the memory freed when the window/tab is closed?

  • How do I accurately handle a batch seperator for SQL from C#

    - by Sam Saffron
    For Data Explorer I would like to add support for a Batch separator. So for example if users type in: select 'GO' go select 1 as go Go select 100 I would like to return the three result sets. Its clear that I need some sort of parser here, my hope is that this is a solved problem and I can just plug it in. (writing a full T-SQL parser is not something I would like to do) What component / demo code could achieve splitting this batch into its 3 parts?

  • Open link in new window with Jquery

    - by mtwallet
    Hi. I am trying to open a few links in a new window using Jquery rather than _blank so my html remains valid. My code looks like this: $(document).ready(function() { $('a[id="external-url"]').click(function(){ $(this).attr('target','_blank'); }); }); This works just fine except when the link is contained within html I have placed on the page using the Jquery load() method. Can anyone explain why and please help with a solution?

  • Suppressing .net's updatepanel submit event handler

    - by wheresrhys
    I'm performing some custom js validation on my forms, triggered by submitting the form $("form").submit(function (e) { var validates = true; // validation code goes in here if (!validates) { e.preventDefault(); e.stopImmediatePropagation(); return false; } }) None of the lines I've included to stop the submit event prevent the .NET control posting back. Is there some way (using js or setting a property in the updatepanel control) of stopping post back?

  • Saving elements to database with $.ajax()

    - by Justin Meltzer
    I'm trying to save dynamically created elements in my application.js file to the database. Would the code look something like this?: $.ajax({ type: "POST", data: { title: 'oembed.title', thumbnail_url: 'oembed.thumbnail_url'} }); Is there anything I'm missing? Assume that oembed.title and oembed.thubnail_url hold the values I want to save, and that title and thumbnail are the database columns.
