JQuery :: Browser Cache And Notmodified Respond For JSON - .ajax({ifModified:true}) Break On Data Respond
Feb 28, 2011
How to fix browser cache and notmodified respond for JSON? jQuery.aja ({ifModified:true}) break on data respond (bug ticked for it was closed like invalid).
Are there any other solution to get 304:notmodified without breaking cache and data respond?
First time browser request [url] returns status 200 OK and nexts 304 Not Modified
Nutshell version: I need to fire off a javascript call whenever an ASP.NET UpdatePanel is updated, and I'm not sure how to do it. Detailed version: I have an ASP.NET page that has several UpdatePanels. Some of these are in my own code and I have access to, some are used by third party controls (e.g. ReportViewer) and I don't have direct access to them.
My website also uses jQuery Mobile to render the controls in a mobile friendly way. The problem I'm having is that whenever something in an UpdatePanel is updated, the newly updated contents don't get re-parsed by jQuery Mobile, and so they revert to their original style(s).
[Code]...
The problem I'm having is that I can't figure out how to make that happen. document.Ready() doesn't refire on an AJAX update. I've tried using $('div').live(),$('div').load(),$('div').change() and a few others (I am adding these to the Master page for the website) but nothing seems to fire off when the DIV updates.
Using $.get() and insertBefore() work great for what I'm doing. But, the data I insert does not respond to events that I have set up. I'm notsurprised by this. I'm sure there is something extra I need to do. But, what is that?
I'm working on creating a little suggestion/autocomplete code for form fields.[code]...
Everything works fine and when I click on the text Foo the form field value is set to foo. But, when I try clicking on a word added to the page by the keyup part of my code above it doesn't work.
I am using superfish and I am wondering how I can go about changing the hover event to click so that when people hover over the links it doesn't do anything until they click them.
I am dumbfounded by this. I have a form where a user enters text for an event which is posted to a database on submit. The form is not running a script and is not necessarily part of a session. The page where you enter data is .asp in name only (it loads shared header and footer files).
After about 30 minutes, when the user clicks the submit button, nothing appears to happen. The page sits there in front of you. Text can still be added to the fields, the button press animation occurs, but there is noone home.
Weirder (?) still is that this only seems to occur in Internet Explorer. Timed trials in FireFox have the form still functioning well after the 45 minute mark.
My customer is obivously upset that his form does not function.
Is it possible to have a JavaScript object that works just like a standard Array, except that when the array is modified, a function gets called which can then do some processing on the array?
Like this: // SpecialArray has a function called Notify function Notify() { // process the array with changes made } var myarray = new SpecialArray("zero", "one", "two", "three"); myarray[1] = "ein"; // after this change is made, function "Notify" is called
I know you can derive a new object from Array, but you cannot directly override the [] operator.
Can you add a function or event handler to a regular Array object that gets called when the array changes?
i am following the example ajaxSubmit[URL].... here my code[URL]... i realized that the showRequest work correctly, shown all my form submit values But it doesn't respond "showResponse(responseText, statusText, xhr, $form)" is not execute. the respond prompt is not pop up
I wrote a little clock with JS and...The clock worked fine until i chose to dynamically add the DIV with createElement to the BODY with appendChild and the clockString to the DIV using innerHTML...and so now when i open it after about 20 seconds safari begins to stall and/or not respond...
START-CODE:
Also just fyi i use some CSS to style the DIV and font-size ect and use the BODY element's onload attribute to run the functions...
I am using a calendar that I have downloaded from a web site. I use this to provide a way for the user to choose a date from the calendar to fill in some date fields. Overall, the calendar works fine except for one problem that I cannot fix: When I add OnBlur event handler to the calendar, the calendar loses its capability to handle OnClick event -- therefore, the user cannot click a day from the calendar. I am trying to use the OnBlur event to hide the calendar as soon as the user clicks outside the calendar. Currently the user can click at a "Cancel" button on the calendar to hide the calendar, or the user can hit <Esc> key to hide it. But I think the calendar will work better if the user can click outside the calendar to hide it.
Attached please find a simplified version of the program that can show this problem. It has one single text field to put date on it. When you click at the text field, the calendar will pop up. This version has the OnBlur event handler commented out. Therefore, you should be able to choose a date from the calendar. But you cannot click outside the calendar to hide it. In order to show the problem, you need to go to the bottom of the program and uncomment this line:
After you have uncommented that line, you will find that you can click outside the calendar to hide it. Unfortunately, you will also find that choosing a date from the calendar only hides the calendar; the date is not being placed into the text field.
In my website I have a couple of forms that you can only see them if certain conditions are applied.
For example - if you're an admin and you search a user, you'll see a form which allows you to edit his information. if you're not you won't see it. if you're already logged in you can't see the registration form, but if you aren't you can.
So I did it with ASP in this way - (this is the registration part)
I've managed to put in the form inside the Response.Write(), and it also has the javascript part like this -
This works perfectly fine.
Now, I've done this twice. the example above is from the registration part which doesn't allow a logged in user to register again.
I'm having problems with the second one - not showing the edit form to a user who can't edit.
This is basically the code -
Now this doesn't do anything... the submit button just ignores the JS file and just submits the form the way it is, unlike the other form which is written pretty much in the same way except for other JS fields/text boxes.
I know the code is written really poorly but thats unfortunately what we've been taught in class and thats all I know.
- I'm not checking for nulls because if a field is empty it means the information won't be edited.
I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
Hint me about an easy and clear way to cache ajax response into client browser WITHOUT using the JQuery? I am unable to find that on google.
I have a page that is loaded using AJAX and it takes long time to load every time (approximately 28 seconds), so I need to cache it to reduce the time. I tried the stored procedure for database, but it did not give me good result, so I want to try the caching.
OK, so I have an AJAX app and am using browser caching to reduce the number of server calls. However, I wanted to be able to clear the whole cache for the browser if the version of my AJAX app has changed.
My plan is to have the version number stored in a cookie on a user's machine. The first thing my app then does upon load is check the version number of the javascript to the version number of the cookie and if they are not the same clear the cache.
Is Json considered the better file format for loadind data via Jquery AJAX? I am going to use it either way, but from a cutting edge stand point, is JSON looked at a more cutting edge since it loads faster. 2. And for that matter is anyone using css3 and E4X? All these seem to require the latest versions of all browsers. Since my goal is to be cutting edge I was thinking to do some stuff in the above listed that require only the latest browser if it is detected, if not use what works in most all browsers? What are cutting edge web app developers really doing at this time?
The following code is working fine in firefox n not working in IE8... I get the Object Expected Error when the code hits the if(GBrowserIsCompatible())..... line in the javascript code. Clear cache and browser history does not work. Does anyone have a resolution for this?
Is there a way in Javascript, or perhaps in HTML, to force a browser to re-render an image on an HTML page after a round-trip between the client and the server ?
In my particular case, the image is changing on the server although the URL for it remains the same, but the browser is still displaying the old image from its cache rather than the new image from its URL location.
I am sorry if this has been asked already. I searched but could not find a suitable answer.I am making a simple RSS reader (using jquery mobile) and I need to be able to cache the resulted feed.To understand better let me explain alittle. I have a page where the users selects the desired category. After that he is taken to a different page where the titles of news are. here the feed is read for the first time. When the user click on a title he is taken to another page where I want to display the content of the selected news article.Sincethe feed was already retrieved on the previous page, I want to be able to cache it so that it won't be retrieved again.Any idea how I best do this?
I have several .js files that are included in various jsp pages.
I've read somewhere(can't remember where?) that the browser caches .js files.
If this is the case is it better to include all of them in the 1st page of my app regardless if they're used in this page & take a performance hit once? - or am I missing something?
Does anybody know how to make FireFox to cache data that comes via XMLHttpRequest? Here is the issue I deal with: - On the web server (apache2) I have a static xml file test.xml - When I download test.xml using XMLHttpRequest, FireFox always gets complete test.xml from the server, thus not using the browser cache (apache sends 200 OK back to FireFox). - If I look into the HTTP request and the HTTP response, I can see that FireFox seems to always set the following request headers: Pragma: no-cache Cache-Control: no-cache - Apache always sets Last-Modified and ETag headers in a response.
I tried the same JavaScript code with IE, and IE definitely relies on its cache: I can see in Apache logs responses with 304 Not Modified code for IE, also HTTP requests from IE have If-Modified-Since and If-None-Match headers. I didn't find any difference in responses Apache provides for FireFox and IE.
