  • Binding Javascript Event Handlers to a an Ajax HTML Response?

    - by John
    Let's say I have the following HTML code <div id="outer"> <div id="inner">Hello World</div> </div> At the end of my HTML page, I use javascript to attach event handlers like so, document.getElementById('inner').onclick = function() {alert(this.innerHTML);} document.getElementById('outer').onclick = function() { /* An Ajax Call where the response, which will be a string of HTML content, then goes into document.getElementById('outer').innerHTML */ document.getElementById('inner').onclick = function() {alert(this.innerHTML);} } In the above code, I am expecting <div id="inner">Hello World 2</div> to come back which requires me to re-attach the onclick event handler. This makes sense because the new response coming back is just a string, and I have to tell the browser that after converting to DOM, i also need some event handlers So my question is, is there a better way to manage event handlers on AJAX response that contains HTML content? I could use inline javascript within the html response, but then it prevents me from achieving non-intrusive javascript. So is there a way to achieve non-intrusive javascript and an efficient way to "maintain" event handlers of ajax html responses?

  • JQUERY - how to get updated value after ajax removes data from within it?

    - by Brian
    I have a an element with thumbnails. I allow users to sort their display order (which fires off an update to the DB via ajax). I also allow them to delete images (which, after deletion, fires off a request to update the display order for all remaining images). My problem is with binding or live I think, but I don't know where to apply it. The array fired off upon delete contains ALL the ids for the images that were there on page load. The issue is that after they delete an image the array STILL contains the original ids (including the one that was deleted) so it is obviously not refreshing the value of the element after ajax has removed things from inside it. I need to tell it to go get the refreshed contents... From what I have been reading, this is normal but I don't understand how to tie it into my routine. I need to trigger the mass re-ordering after any deletion. Any ideas gurus? $('a.delimg').click(function(){ var parent = $(this).parent().parent(); var id = $(this).attr('id'); $.ajax({ type: "POST", url: "../updateImages.php", data: "action=delete&id=" + id, beforeSend: function() { parent.animate({'backgroundColor':'#fb6c6c'},300); $.jnotify("<strong>Deleting This Image & Updating The Image Order</strong>", 5000); }, success: function(data) { parent.slideUp(300,function() { parent.remove(); $("#images ul").sortable(function() { //NEEDS TO GET THE UPDATED CONTENT var order = $(this).sortable("serialize") + '&action=updateRecordsListings'; $.post("../updateImages.php", order, function(theResponse){ $.jnotify("<strong>" + theResponse + "</strong>", 2000); }); }); }); } }); return false; }); Thanks for any help you can be.

  • git local master branch stopped tracking remotes/origin/master, can't push

    - by Paul Smith
    Just when I thought I'd got the hang of the git checkout -b newbranch - commit/commit/commit - git checkout master - git merge newbranch - git rebase -i master - git push workflow in git, something blew up, and I can't see any reason for it. Here's the general workflow, which has worked for me in the past: # make sure I'm up to date on master: $ git checkout master $ git pull # k, no conflicts # start my new feature $ git checkout -b FEATURE9 # master @ 2f93e34 Switched to a new branch 'FEATURE9' ... work, commit, work, commit, work, commit... $ git commit -a $ git checkout master $ git merge FEATURE9 $ git rebase -i master # squash some of the FEATURE9 ugliness Ok so far; now what I expect to see -- and normally do see -- is this: $ git status # On branch master # Your branch is ahead of 'origin/master' by 1 commit. # nothing to commit (working directory clean) But instead, I only see "nothing to commit (working directory clean)", no "Your branch is ahead of 'origin/master' by 1 commit.", and git pull shows this weirdness: $ git pull From . # unexpected * branch master -> FETCH_HEAD # unexpected Already up-to-date. # expected And git branch -a -v shows this: $ git branch -a -v FEATURE9 3eaf059 started feature 9 * master 3eaf059 started feature 9 remotes/origin/HEAD -> origin/master remotes/origin/master 2f93e34 some boring previous commit # should=3eaf059 git branch clearly shows that I'm currently on * master, and git log clearly shows that master (local) is at 3eaf059, while remotes/origin/HEAD - remotes/origin/master is stuck back at the fork. Ideally I'd like to know the semantics of how I might have gotten into this, but I would settle for a way to get my working copy tracking the remote master again & get the two back in sync without losing history. Thanks! (Note: I re-cloned the repo in a new directory and manually re-applied the changes, and everything worked fine, but I don't want that to be the standard workaround.) Addendum: The title says "can't push", but there's no error message. I just get the "already up to date" response even though git branch -a -v shows that local master is ahead of /remotes/origin/master. Here's the output from git pull and git remote -v, respectively: $ git pull From . * branch master -> FETCH_HEAD Already up-to-date. $ git remote -v origin [email protected]:proj.git (fetch) origin [email protected]:proj.git (push) Addendum 2: It looks as if my local master is configured to push to the remote, but not to pull from it. After doing for remote in 'git branch -r | grep -v master '; do git checkout --track $remote ; done, here's what I have. It seems I just need to get master pulling from remotes/origin/master again, no? $ git remote show origin * remote origin Fetch URL: [email protected]:proj.git Push URL: [email protected]:proj.git HEAD branch: master Remote branches: experiment_f tracked master tracked Local branches configured for 'git pull': experiment_f merges with remote experiment_f Local refs configured for 'git push': experiment_f pushes to experiment_f (up to date) master pushes to master (local out of date)

  • Loading dynamic content and rewrite URL on Hashchange event with Jquery Mobile

    - by user3611500
    I'm building a mobile version for my website using Jquery Mobile API. The framework provides automate AJAX navigation processing. But as far as i know it require "real" pages for loading purpose. What i want to do is override the automate navigation process of it and process the hashchange on my own. But i can't not rewrite the url using window.hashChange, which is running well on my non-mobile website version : $(function () { $(window).off().hashchange(function () { if (location.hash.length > 1) { PageSelect(); } }); $(window).hashchange(); }); I just only want to take advantage on jquery mobile interfaces, i don't want anything with its automate ajax navigation stuff ! I tried to disable it using ajaxEnabled() but got no luck.

  • Creating Wizard in ASP.NET MVC (Part 2)

    - by bipinjoshi
    In Part 1 of this article series you developed a wizard in an ASP.NET MVC application. Although the wizard developed in Part 1 works as expected it has one shortcoming. It causes full page postback whenever you click on Previous or Next button. This behavior may not pose much problem if a wizard has only a few steps. However, if a wizard has many steps and each step accepts many entries then full page postback can deteriorate the user experience. To overcome this shortcoming you can add Ajax to the wizard so that only the form is posted to the server. In this part of the series you will convert the application developed in Part 1 to use Ajax.http://www.binaryintellect.net/articles/8e278bfa-7244-4e3e-b5aa-2954a91331da.aspx

  • Here we go again - quest for web hosted forum via javascript

    - by jim
    Hello all, disclaimer If this is the wrong location for this question, then please advise me accordingly. backgound I've been using Disqus and intense debate as a 'comments' service for a variety of my sites to great effect and love the fact that i get alot of the facebook/twitter integration 'for free', as well as the SEO benefits. request To this end, does anyone out there know of similar services that can be used to pull entire forums/threaded discussions into the app in a similar fashion (i.e. via ajax webservices). google has been at a loss to turn anything up on this front and i'm therefore wondeing if it's unlikely that such a 'service' exists. respect hope this stikes a chord out there... btw - altho using this in asp.net mvc, I'm aware that this technology could be used on any platform capable of consuming javascript via ajax, thus the wide spread of 'tags'.

  • Application use on website

    - by Palmer
    Is there a good way to run a C# application on clientside in lieu of JavaScript? I have done some front end work with JavaScript and backend C# for web developing at an old job, but I am interested in hosting a website myself soon. I have a C# application I would like to be open source, but before people care to download I'd like them to be able to use it. At its basic level it's a simple text editor, but there's much more to it in the nitty gritty. I could write it in JavaScript, but it would require me to keep documentation and up to date changes on JavaScript and C# in that case. I was thinking of creating an AJAX panel and somehow loading my winform application into a frame, but I don't know how or what words to google because I've never done it before except AJAX.

  • Best way to redirect users back to the pretty URL who land on the _escaped_fragment_ one?

    - by Ryan
    I am working on an AJAX site and have successfully implemented Google's AJAX recommendation by creating _escape_fragment_ versions of each page for it to index. Thus each page has 2 URLs: pretty: example.com#!blog ugly: example.com?_escaped_fragment_=blog However, I have noticed in my analytics that some users are arriving on the site via the "ugly" URL and am looking for a clean way to redirect them to the pretty URL without impacting Google's ability to index the site. I have considered using a 301 redirect in the head but fear that Googlebot might try to follow it and end up in an endless loop. I have also considered using a JavaScript redirect that Googlebot wouldn't execute but fear that Google may interpret this as cloaking and penalize the website. Is there a good, clean, acceptable way to redirect real users away from the ugly URL if for some reason or another they end up arriving at the site that way?

  • How to repeat a POST request using Chrome's developer tools?

    - by Luke The Obscure
    Not sure if this is the right stack exchange to ask this, but here goes... I'm trying to wean myself off of Firebug, which has served me very well for a lot of years. One feature that seems to be missing in Chrome's dev tools is the ability to repeat an AJAX POST. In firebug I can right click on the request in the console and hit "Open in new tab" and the request is repeated exactly as it was originally sent. In Chrome, the same action just does a normal GET on the link, without any of the post data. Is there any way to repeat an AJAX POST in Chrome's dev tools?

  • How to identify the client is a search robot?

    - by Yau Leung
    I have built my entire site using AJAX (indeed it's GWT). I have also implemented AJAX crawling proposed by Google. However, after the implementation, I found that neither Yahoo , Bing, nor Baidu implemented that scheme! I'm wondering if there is a way to identify the web client is a search robot. If they are, they will be shown the HTML snapshot I created. It will be best if I can identify them in APACHE level, then I can just do a mod_rewrite. But it's still ok if I can do that in PHP or GWT.

  • If my URL's are static, but then parsed by Javascript, does that make it crawlable?

    - by Talasan Nicholson
    Lets say I have a link: <a href="/about/">About Us</a> But in Javascript [or jQuery] catches it and then adds the hash based off of the href attribute: $('a').click(function(e) { e.preventDefault(); // Extremely oversimplified.. window.location.hash = $(this).attr('href'); }); And then we use a hashchange event to do the general 'magic' of Ajax requests. This allows for the actual href to be seen by crawlers, but gives client-side users with JS enabled an ajax-based website. Does this 'help' the general SEO issues that come along with hashtags? I know hashbangs are 'ok', but afaik they aren't reliable?

  • How to manually list set of urls for search engines to index

    - by MarutiB
    So I have created a video website which has thousands of videos and thousands of videos get added to it on a daily basis. Here is my problem :- I have created a website which basically loads the skeleton in html and puts all the content through javascript and Ajax. The problem is search engines aren't going anywhere except for the home page. Is there a way say in robots.txt where i give a link to a single html which has links to all these videos ? I agree my site is not accessible for a non-javascript user but stats show that this ratio is very low ( 0.2 % ). Is there a way I can still keep the complete AJAX website and still get each individual videos listed on google ?

  • Google indexing pages with #! although we don't have any

    - by Benjamin Gruenbaum
    Our company has developed a Single Page Application using AngularJS and its routing. Google indexed our site decently with JavaScript but it did not index some pages very well so we have developed an HTML only version. We have followed the Ajax Crawling Specification posted here and have a <meta name='fragment' content='!'> tag and canonical urls. We expect http://www.example.com/foo/bar to be fetched from http://www.example.com/?_escaped_fragment_=/foo/bar. However, we have found out that when we rolled the AJAX specification we now have all pages indexed twice, once with the JavaScript version as http://www.example.com/foo/bar and once with the new version as http://www.example.com/#!/foo/bar. This is harmful to us since it's duplicate content and also mis-representing out site. I have tried looking for similar questions here and in the Google product forum but could not come up with anything.

  • Git: push via ssh to a root owned repository with ssh root logins disabled

    - by anthonysomerset
    is that even possible? Summary, i'm running puppet master on a server and ideally we want root logins via ssh disabled, we want to force all access via sudo if root access required however we have puppet installed using a git repo to manage the manifests, this repo is currently owned by root and currently i only know of 2 solutions (less ideal) allow root access via key auth only - if so, what can i lock it down to to only allow the git push commands? own the repo in /etc/puppet as a different owner - will puppet work reliably with this?

  • push commits to git (gitolite) repository messes up file permissions (no more trac access)

    - by klemens
    already posted here so feel free to answer there. everytime i commit/push something to the git server the file permissions change (all added/edited files in the repository have no read and execute access for the group). thus trac can't access the repository. do I need to change permissions of the folder differently? chmod u=rwx,g=rx,o= -R /home/git/repositories or do i need to setup gitolite somehow to write files with different permissions??? regards, klemens

  • General directions on developing a server side control system for JS/Canvas Action RPG

    - by Billy Ninja
    Well, yesterday I asked on anti-cheat JS, and confirmed what I kind of already knew that it's just not possible. Now I wanna measure roughly how hard it is to implement a server side checking that is agnostic to client input, that does not mess with the game experience so much. I don't wanna waste to much resource on this matter, since it's going to be initially a single player game, that I may or would like to introduce some kind of ranking, trading system later on. I'd rather deliver better more cool game features instead. I don't wanna have to guarantee super fast server response to keep the game going lag free. I'd rather go with more loose discrete control of key variables and instances. Like store user's action on a fifo buffer on the client, and push that actions to the server gradually. I'd love to see a elegant, generic solution that I could plug into my client game logic root (not having to scatter treatments everywhere in my client js) - and have few classes on Node.js server that could handle that - without having to mirror/describe all of my game entities a second time on the server.

  • Where do I read more about building an architecture like Google has? [on hold]

    - by user107148
    I want to develop a program that watches and traverses a rather big network for data. This data should then be available to search through with my program, maybe through a web interface or something. My intuitive thought at the moment is to build an architecture kind of like the one Google has. One "front-end" (the Google Search page) which is essentially a regular web application and one "back-end" (which in Google's case traverses the web). Now for the hard part: If I decide to make such a system, how should communication be done between these parts? One idea I had is to use some kind of database that both the back-end and front-end can access, but then comes the issues of concurrent writes and reads. Another issue with just using a database to communicate is that it makes it hard to "notify" the other part when something changes. Let's say that I want the "front-end" part to push changes to the UI when a change is noticed in the back-end. Then the back-end would have to have some way of notifying the front-end of this.

  • how to push a string address to stack with assembly, machine code

    - by Yigit
    Hi all, I am changing minesweeper.exe in order to have an understanding of how code injection works. Simply, I want the minesweeper to show a message box before starting. So, I find a "cave" in the executable and then define the string to show in messagebox and call the messagebox. Additionally of course, I have to change the value at module entry point of the executable and first direct it to my additional code, then continue its own code. So at the cave what I do; "hello starbuck",0 push 0 //arg4 of MessageBoxW function push the address of my string //arg3, must be title push the address of my string //arg2, must be the message push 0 //arg1 call MessageBoxW ... Now since the memory addresses of codes in the executable change everytime it is loaded in the memory, for calling the MessageBoxW function, I give the offset of the address where MessageBoxW is defined in Import Address Table. For instance, if MessageBoxW is defined at address1 in the IAT and the instruction just after call MessageBoxW is at address2 instead of writing call MessageBoxW, I write call address2 - address1. So my question is, how do I do it for pushing the string's address to the stack? For example, if I do these changes via ollydbg, I give the immediate address of "hello starbuck" for pushing and it works. But after reloading the executable or starting it outside of ollydbg, it naturally fails, since the immediate addresses change. Thanks in advance, Yigit.

  • using jquery $.ajax to retrieve data and push data into javascript array through the success functio

    Hello All, I have a function that I'm trying to retrieve values using $.ajax and push the returned data into an array called output. Problem is the success function will not allow me to push the results into the array. see below for code. var getValues = function(el) { var value = ($(el).val()); if(value == '' || $(el).attr('disabled')) { return []; } var string = 'value=' + value; var output = []; $.ajax({ type: "GET", url: 'shocklookup_callback.php', dataType: "string", data: string, success: function(data) { } }); //output.push({ text : value + 'test', value : value + 'test1'} ); return output; }; Any ideas of what I can put in the success function to be able to push the data into the output array? Also I need to be able to return the output array to the original function getValues. If this doesn't' make a whole lot of sense please let me know and I'll try to explain better. Thanks, Dane

  • Vb.Net web browser control not firing document complete with AJAX web site.

    - by ajl
    The VB.Net desktop app uses the IE browser control to navigate the web. When a normal page loads the document_complete event fires and I can read the resulting page and go from there. The issue I am having is that the page I am driving is written with AJAX, so the document complete event never fires. Furthermore, when you view the source of the page after it loaded a new portion via AJAX, it hasn't change. How are people handling this? What are my options?

  • ASP.NET MVC Ajax Form: Is enctype correct? Why doesn't file get uploaded?

    - by Fabio Milheiro
    In the case that the user doesn't have Javascript activated, in order to draw a form, I begin this way: <% using (Html.BeginForm("Create", "Language", FormMethod.Post, new {enctype="multipart/form-data"})) { %> If the user has Javascript activated, the following code is used: <% using (Ajax.BeginForm("Create", "Language", new AjaxOptions { UpdateTargetId = "CommonArea" }, new { enctype = "multipart/form-data" })) { %> The problem is this: In the first case, I can get the file uploaded using the following instruction in the business layer: // Get the uploaded file HttpPostedFile Flag = HttpContext.Current.Request.Files["Flag"]; In the second case, this instruction doesn't work. How do I know upload that file using the Ajax.BeginForm? Is the code right? Can anyone more experience advise about using jQuery plug-in to upload file before the form submission? Thank you

  • What are jQuery best practices regarding Ajax convenience methods and error handling?

    - by JonathanHayward
    Let's suppose, for an example, that I want to partly clone Gmail's interface with jQuery Ajax and implement periodic auto-saving as well as sending. And in particular, let us suppose that I care about error handling, expecting network and other errors, and instead of just being optimistic I want sensible handling of different errors. If I use the "low-level" feature of $.ajax() then it's clear how to specify an error callback, but the convenience methods of $.get(), $.post(), and .load() do not allow an error callback to be specified. What are the best practices for pessimistic error handling? Is it by registering a .ajaxError() with certain wrapped sets, or an introspection-style global error handler in $.ajaxSetup()? What would the relevant portions of code look like to initiate an autosave so that a "could not autosave" type warning is displayed if an attempted autosave fails, and perhaps a message that is customized to the type of error? Thanks,
