I'd like to make an HTTP request using JavaScript but not with the XMLHttpRequest object. I'm attempting to make this request to a different domain to get information and the security of modern browsers won't allow this with the XMLHttpRequest object.
Is there another way to do this in JavaScript? Oh and I'm not taking advantage of the asynchronous nature that object either, so that's not a criteria for a potential solution.
Say I wrote an ajax script to send out HTTP requests via ajax. Any
cookies that I have associated with that site will be sent along with
this HTTP request. Is there a way to prevent this from happening? I
tried the following to no avail:
http.setRequestHeader('Cookie','');
Can I do the following without my program crashing? [code]...
I have created an application that does something similar to the code I just posted. However, my program crashes intermittently. Sometimes it will crash after calling jQuery.get() a few times (with several http requests still pending). Other times it will get through all of them just fine.
I want to know if Ajax can handle that many asynchronous requests without crashing? Can someone look at this to see if there is something I am missing?
I was wondering if the jquery out of the box allows for repeated ajax requests at a certain time interval to update elements on the page. I found a plug in that can do this:Just wanted to make sire i can ot inherently do it with jquery.
View 6 Replies View RelatedI'm doing some data processing and I need to pull data out of html snippets. Works fine, but when I load in the html it's wanting to make a bunch of secondary http request for resource files, images, css, etc. which slowes the process down. My loads go from 40b to 350b. is there a way to prevent the browser, or jquery or javascript, or whatever is forcing the load of these assets to just knock it off?
View 1 Replies View Relatedthis may be more of an "html" issue, but I'll wing it.
i've got a multi-language site, where the home-page of each language group
features a link to a popup window that offers background info on site
management. the popup is fired by a javascript function, when they click
the site management link. there's also a "window close" function button so
they can nuke it as they please.
now, oddly, people who search for my site in the chinese language on google,
are sent directly to the site management popup window, which of course,
opens in their "full" browser window, and which also has no links back to
the main site, because it's meant to open only as an "accessory" to the main
site.
my question is this: is there any way, with Javascript, that I could
determine if they arrived at this window from "off-site" (ie, a google
search), and therefore offer such "off-site" visitors a link back to the
principal site, a link that would be hidden for visitors who clicked the
popup window from my own site?

Is it possble to do a HTTP post request inside JavaScript? - That is I don't
want to use a HTML FORM, but need a JavaScript to post a value to a PHP script not encoding the parameters in a URL.
I am trying to write a script which will allow me to read the contents of an
HTTP web page into memory, parse the data, and output a calculated value.
The HTTP page is on a web enable appliance - I am reading some data out of a
table for further calculation. I can't modify the web appliance, only read
the text data.
I've written a script on my Windoze PC that successful uses a MSXML2 ActiveX

how do I know when the browser is making a request to the server? I am
not having an onclick event for EVERY hyperlink, submit, etc. There
must be some javascript function that I can overwrite that will allow
me to do something when the browser requests something from the server.
My plan is whenever a browser is about to request something from the
server to create a time stamp and then compare this time to the time
when the page returns from the server. This will allow me to measure
performance.
I've noticed that IE have different security approach when loading a
page from an inner intranet or when loading a page from the web.
Is there a way in Javascript to know when your page is running by an
outsider and when by an insider? How the browser knows?
I found a bug in IE6, though it is known already. If I have a CSS
background property set to some image, such as
background:url(myimg.gif);, and I apply this property to some html
element, say DIV, and refresh DIV every 10 seconds, background image
is reguested every 10 seconds for IE6, too.
The fix which I found did not fix the problem:
try {
document.execCommand("BackgroundImageCache", false, true);
} catch(err) {}

I can't see the requests of the forms by firebug to debug. Does anyone know if have any option or any way to do this?
View 3 Replies View RelatedIt looks like IE is caching the response for some AJAX requests here. The app I'm working on is a catalog of sorts. Clicking the link for a category loads a set of "items". Those, in turn, may be deleted from the admin view. The delete works fine (I checked the DB) but, when loading the same set of category items, I'm seeing the list unchanged. That is, the thing that was deleted is still there. Sorry for the crap explanation but I'm not really sure of a better way of putting it. Bottom line is, has anyone seen this sort of behavior with IE before? Can it cache the result of an AJAX request like that? And, if so, how can I guard against that? Can I set cache-control headers for an AJAX request?

This might seem like a silly question..First issue. If i have a response and i'd like to update both text div and a status div how would i go about doing this. I've seen that jQuery has a few options such as OnSuccess etc?
Say that i post a comment and obviously you'd want to update some kinda statusbar on your website with the info that the message was posted successfully with ajax. (otherwise it might slip by the user unnoticed since ajax is kinda discrete)
Would it be a good way to for instance check the responseText if it contains anything and if it does you simply write a successmessage by grabbing a div from JS and if the responseText contains a custom error code lets say 1 you'll update the statusbar with a deny message?
Second thing. I've currently created an Ajax search on my site which activates whenever the user press or unleash the button. The issue is that if the user types fast enough it comes stuck showing the Loading.gif constantly. Could this be due so many requests opening and that i have a sleep on the server-side and if so how would you do it instead? I am using a serversleep of 1 second to have the Ajax pic appear consistently.

In my current project, I am using SJAX (i.e. synchronous AJAX) requests instead of pure AJAX requests in several places for better usability. One place is on the "unload" event, where the XMLHttpRequest must be synchronous in order for the program to work.
Anyway, when there is latency on the server, especially in peak traffic hours, it can be confusing to the user to see a frozen page for a couple of seconds while the SJAX request loads. As such, it would be beneficial to have a "loading" div reveal itself while the loading is taking place.
Here is the concept I currently have in place:
Code JavaScript:
document.getElementById("sjaxsubmitting").style.display = "block";
// Start Request
reqobj.open("POST", "myfile.php", false);
[Code]....
This works as expected in Firefox and Opera, although Opera is a little sluggish at first. However, Safari and Chrome continue to show the frozen screen without displaying the loading div, despite this code. I have not yet tested IE. Oddly enough, when I put a quick alert like "alert('hi there!');" before "Start Request" and after the display activating script, the loading div will appear in WebKit and will remain in sight for the duration of the request.
What could I change to make WebKit display the div in the same way Firefox does?
I have a jsp page using ajax that has a button with an action. The action sends multiple ajax requests. The response from these requests is to be used to update a progress indicator to show the servers current progress. I can see from the debug that I am getting the 1st response. I think it is the way how I have implemented the further requests. I think this is down to my javascript knowledge, which isnt very much. Also I assume using multiple requests in this way is the correct thing to do? I have spent ages trawling the internet trying to get a solution.
