I'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 RepliesSay 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','');
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.
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?
this 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?
I have an array of objects. My object definition is given below:
function tempArray(code,height,weight)
{
this.code = code;
this.height = height;
this.weight = weight;
}
I used the following function to sort.
function sortBy(prop,arr) {
sortProp=prop;
arr=arr.sort(sortFunc);
}
function sortFunc(part1,part2) {
if (part1[sortProp]>part2[sortProp]) retVal=-1;
else if (part1[sortProp]<part2[sortProp]) retVal=1;
else retVal=0;
return retVal;
}
This however allows me to sort only by one criteria. I need to sort by
weight first and then by height for those items that have the same
weight.
I know this is for Javascript, but I am trying to find an JSP newsgroup or a
very good JSP resource on the www.
I am working on an application (for internal company use) that is meant to be viewed over three monitors. I'm wondering how to accurately position windows on the secondary and tertiary monitors. If they all have the same resolution (say 1280x1024), can we assume that the second monitor begins at 1281, and the third begins at 2561?
View 2 Replies View RelatedI'm in the process of learning JavaScript. I picked up a "JavaScript for dummies" book at the library and it wasn't going too well. It was poorly written and made it difficult to understand things in the later chapter.
What is the best online resource to learning JavaScript? Preferrably one that is good at explaining format ( I often find myself wondering if certain aspects in my script need ()'s or a "=" sign).
For example, HTML has tags and that is what forms the mark up. I know JavaScript has multiple aspects (functions, objects), but I want an online resourcethat properly explains the format of these aspects.
i am looking for a way to have superfish only hide the secondary navigation but not other levels - for example,i have a horizontal nav bar with my primary navigation on it - i would like for the secondary AND tertiary navigation to show when i mouseover a main nav element.is there any way to show the 3rd level nav inline?

my issue is both a php and a javascript (AJAX) one its one or the other. I have two combo boxes one dependant on the other, populated by AJAX but when I submit the form the secondary combo is not being registered as a php $_POST['var'] in the following action page. The secondary combo is contained and altered using divs and inner.HTML. Is this an expected behaviour or is my issue else where?
View 3 Replies View RelatedIs there an extension or plugin that could take a url to some media -- video, audio, image -- and just load it / display it on the page? I came across jQuery Media [URL]... and it looks like a good start at what I'd need. Although it just focuses on video and audio, not general images.
View 3 Replies View Relatedhow 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) {}
Code:
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.
