Can JS Suss Out "on-site" Vs Off-site HTTP Requests?
Dec 5, 2006
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?
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:
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?
Basically, I registered for a free board at one of the various sites because my server doesn't support .cgi scripts. I want to know if there is a way to have the data from a form on my site post to the board site -A user would fill in my form, click submit, and a new post would appear on the board site -as if they had entered it there. If you can point me in the right direction, I would be grateful. Here is my thinking.
A) I can't locate the script that they use to perform a "submit"; so I thought I might enter their <head> data (as far as xmlns, href, etc) in my <head>; that my website might call up their script files, css sheets, etc.
B)I could code my own Javascript function to send my form data to their site. If I knew how to simulate a mouseclick on someone else's site, I could have the script "click" there, paste the data, and hit the submit button. But I don't.
C) I could size their site down to the form itself and put it in a frame on my page
Option C is clearly easier, but I would prefer option A or B. I have time and will happily do the research myself; provided that I know if approach A or B is even feasible.
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?
I'm making a fansite for a game called RuneScape and I'm a bit stuck on this part.
What I need for my website is, a page that will have the prices (min, middle, and max) of things from this [URL] or other items, which will be chosen later on.
Here are two example sites that I am wanting to ... do the same thing as them.
I was looking at the Web SQL spec on the W3C site (here)the example code
Code: function prepareDatabase(ready, error) { return openDatabase('documents', '1.0', 'Offline document storage', 5*1024*1024, function (db) {[code]....
I don't understand how/why prepareDatabase is set twice.Is there a term for this? I can't for the life of me think what it is. I know I've seen it before though.
I wondered if there was a way to blur my whole site except a popup-div when a link is clicked - just like lightbox fades out the page, just with a blur effect instead:[url]...
There are times that I am using another person's computer who has no knowledge of updating HTML and does not even know if he has the necessary programs to do the FTP.
I may see a minor problem with my site and would like to change it on the fly. What I would like to know are the answers to the following questions.
1. Is there any way to display unformated HTML within a web page without using the browsers source facility?
2. Is there a way to modify it? Maybe showing it in a form textarea.
3. Is there a way for javascript or a form to do an FTP back to the web site? This would obviously require id and password.
Is there any program out there that can scan a website for javascript errors? Just trying to fix some EXTREMELY minor problems on a very large (20,000 pages) web site...
Is it possible with javascript to retrieve somebody's Computer name when he connects to a webserver? (So the webserver receives the computername of the client).
I have a web application that has basic authentication turned on (IIS). What I would like to accomplish is detect whether user is navigating away from the site or simply going to the different page using JavaScript. I am aware that it is easy to detect where you came from (referrer), but I haven't been able to find a way to where you're going to. I did my fair amount of research online, but I couldn't find a solution for this.
However, my boss told me that he has seen a website that detects the fact that you're navigating away from your site. Does anyone know anything about this?
The next step after Grant Wagner's simple solution to my "Get computer name" thread, is to automatically add the web application's site to the list of trusted sites in IE.
Obviously, the user should get a popup first that says "Do you want to add this site?"
I've looked through the Wscript doco in MSDN, but can't find a way of manipulating this browser setting.
I'd expect it to be something like "setHomePage" - namely "addTrustedSite".
Is the UI section of the site down? I have a few websites that link to it and they're all taking forever to load, seemingly hanging when "waiting for ui.jquery.com..."
You've all seen it before banner codes/rss feed displayers/twitter feeds/etc. All you do is copy and paste a <script src="[URL]"></script> somewhere on your website and it retrieves the html from the remote server and displays it on your site. I have a back end php page that pulls the required information from my DB based off a userid passed to it i.e.: mywebserver.com/display.php?id=xxxx Is the javascript just a simple ajax call to my php page passing straight on the userid passed to it or is there something more complex to it? I was always under the impression you couldn't do remote ajax calls to a page on a different server, which if I get this right a script off my server included on another domain becomes a member script of that domain and not my own?
I've got the following site that loads great in FF and Chrome (no surprise), but is terribly slow in IE7. It's even quick in IE6, but not 7. Here's the site code...
Now I'm using JQuery in a couple places, but it's by no means nothing crazy. The page is fairly simple.
I thought of preloading the main content images, but even after they are loaded in the cycle, the loading time is still slow.
