- two websites, one on domain1 and the other on domain2
- domain1 opens a new window which is a javascript app from domain2
- domain1 needs to communicate with the javascript app on domain2
The problem occurs in that last step. Browsers don't allow script access
across domains for security reasons, rightly so. Nonetheless, I still
need to communicate with the application. I can reload the window
passing the necessary commands through the url, but this is slow because
the whole javascript app must reload.
Anyone have any ideas about a way around this limitation that would be
semi-efficient, at least more efficient than reloading the app? Signing
the script isn't an option for cost reasons. I have control over both
sites, so I can do anything that needs to be done.
I am working on this web site with some of the pages at a different domain name. It is actually one web site, but some of the pages are at a different domain name (different root, too) although the IP address is the same.
Basically, there is one main window, and a pop-up window. They need to "talk" to each other - mainly access properties to see what page they are on.
As, the web site is on two domain names, there is a security problem when the pop-up window tries to read properties in the main window, or vice versa.
Is there anyway to share information between the two? Or is it hopeless?
Its a message system im putting together. I would like users to be able to have a friends list. I know the php to manage the friends list but i dont know the javascript to achieve my goal here.
I want them to be able to click the Friends List link and have the box pop up. Then have them able to click the persons name and have that persons id show up in the Mail To: Text Box in the first window. Anyone know how to go around doing this. I know its possible cause hotmail does it.
I have a remote client that has a ridiculous latency over port 80, and we're looking to increase response time. Due to other factors, they do have a decent response time when sending email.
It's a long shot, but I was wondering. Is there any way to open a port other than 80 via browser using javascript?
I'm trying to come up with a way within a client-side web page of uploading a couple files to a server-side PHP program without using a <form...>. I don't want to give up the page which happensafter the <form...> executes. Instead, I want to upload the files, then execute a <form...> for another purpose.
I'm trying to send some form values via JS from one frame (a PHP application I control which creates form fields from database values) to another (a shopping cart on another site) - but I can't do this because normal scripts are barred from setting values on pages from other servers... unless the script is signed.
So, am I right that I HAVE to use a signed script to accomplish this goal? Are there lots of cross-platforms issues in getting extra privileges for signed scripts? (Does IE even recogize signatures the way NN does?)
I've never worked with signed scripts before - are they worth the hassle?
I'm trying to work with XML DOM for the first time as I need to grab a value from a SOAP request. I've been following this: [URL], which says modern browsers won't parse xml files from another server for security reasons. How would I got about doing this then? I've been using the price of crude oil as an example [URL] and want code portable enough to put on something like Tumblr, so I don't think I can actually save the file locally first.
I am wanting to make an ajax call across domains. Im attempting to call an external api with json data and (hopefully) receive a response. It's a mapquest api to obtain driving routes.Is there a mechanism in jQuery that will allow me to make a cross-domain ajax call?
function validateEmail(strValue) { var objRegExp = /(^[a-z]([a-z_.]*)@([a-z_.]*)([.][a-z]{3})$)|(^[a-z]([a-z_.]*)@([a-z_.]*)(.[a-z]{3})(.[a-z]{2})*$)/i; return objRegExp.test(strValue); }
what should i add to reject email addresses from hotmail.com and yahoo.com?
With Google Analytics, you have to create a new profile for each domain, and post different code on each domain.
I'd like a traffic stats script (or website) where you can just add the same code for any domain, and that domain will be automatically tracked, even if it's a new domain. So if I have 100 domains and then add the same code to the 101st domain, it will track that domain fine.
Doesn't matter if the script needs to be hosted on your own server, or if it's 3rd party like Google Analytics. It can be commercial too if it's got an unlimited domain license. Anyone know of something like this?
I have a site that uses 2 domains to forward to the IP no. (a .org.uk and .co.uk). The site uses the Google Map API for a map on the site, however the API key is locked to the individual domain (I do have two keys for both the domains). I found the following Javascript which is supposed to switch the key depending on the domain that is accessing the page.
I'm working on some code and am running into brick walls. I'm trying to write out Javascript with Javascript and I've read the clj Meta FAQ and didn't see the answer, read many similar posts (with no luck though), and searched through the IRT.ORG Faqs (www.irt.org/script/script.htm).
The Javascript is designed to open an popup window and then inside that window call another script which will resize that window. There may be another way around this but the reason I tried this approach initially was that I wanted to call the onload handler in the popup window to resize the image only after the image had completely loaded. I've had some code in the primary Javascript file (showimage.js) before that works if the image has been cached but on the first load, it doesn't resize properly which tells me it is probably because it is trying to resize the window based on the image size but it isn't completely known at that point. So I removed that code and tried placing the resizing code in the second Javascript file (resizewindow.js). BTW I've tried other code to open a popup image and automatically size it ie Q1443 at irt.org but that doesn't do exactly what we need.
Even if there is another way to do this with one file, I still want to figure out why this isn't working in case I run into it in the future.
I thought what I would need to do to use document.writeln to write Javascript would be to escape any special characters and to break apart the script tag ie
document.writeln('</SCRIPT>');
would become
document.writeln('</SCR' + 'IPT>');
I have a HTML page and 2 Javascript files. All files are in the same directory and have permissions set correctly.
Here are the 3 files (keep in mind wordwrap has jacked up the formatting):
index.html ---------- <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Test</title> <SCRIPT type="text/javascript" LANGUAGE="JavaScript1.1" SRC="showimage.js"> </SCRIPT> </head>
<body> Click the house<BR> <A ONCLICK="newWindow1('house1.jpg','Nice House')"><IMG SRC="house1thumb.jpg"></A> </body> </html>
showimage.js ------------ function newWindow1(pic,sitename) {
resizewindow.js --------------- function resizewindow() { // Do resizing here. // Right now this isn't being executed alert("resizing window"); }
Can anyone provide some pointers as to why this javascript is failing? I'm using IE6 on Win2k and when I click on the image to open the popup window, it does open the window but it is white with no content and the system immediately goes from about 4% CPU usage to 100% and consistently stays there until I kill that window with the task manager.
Attached is a simple HTML file that adds and delete rows. In the add row function I set an attribute "onClick" this triggers the testMessage() function. When I try this in Firefox it works just fine however on IE it just refuses to work.
What is interseting is the ROW that already exists has a similar 'onClick' event which works when the page is loaded, but subsequent "row" additions to the table to not work in IE. Code:
I'm getting errors in Firefox everytime I try to run this frame resize code, but it works fine in IE. I can't seem to figure out what the problem is with it.
The error is: Error: theFrame has no properties Line: 8
The line that the javascript console is showing an error for is in italics.
I'm already past the basics of Javascript, and i need something that takes me to the other level and teaches me the new technologies and cool stuff (drag&drop, AJAX, OOP in javascript, maybe XUL...etc). So far i found these two books:
1. Sitepoint's "The JavaScript Anthology: 101 Essential Tips, Tricks & Hacks". 2. Worx's "Professional JavaScript for Web Developers (Wrox Professional Guides)"
Both seems to cover very insteresting topics, but i can only buy one of them. So which one do you suggest?
and by the way, i've read the sample chapter 5 of Sitepoint's book, and it seems like the author(s) just put the solutions/codes there and let you figure them out on your own. Is this how the rest of the chapters are?
This is a question about defensive web browsing. Ocassionally I run into a page whose JavaScript does something that I find obnoxious. I would like to turn off JavaScript only for that page (instead of disabling it globally). It would be cool if there were some way to do this through a "bookmarkable" JavaScript snippet using the javascript: pseudoprotocol. Does anyone know any trick to do any of this?
I am looking for a method to extract the links embedded within the Javascript in a web page: an ActiveX component, or example code in C++/Pascal/etc. I am looking for a general solution, not one tailored to a particular page/script.
Hopefully, the problem can be solved without recreating a complete Javascript interpreter. Any ideas?
I have some javascript that I have written into the <body> section and it works great. But I would like to make it into a javascript function and define the function in the <head> section. Then in the <body> section write a small bit of javascript that would call the function() object. Code:
I would like to know how to write javascript such that, a part of it isnt considered as script, & rather as HTML. Code:
Ok, the layer div can be written using document.write. But, Google ad itself is a javascript isnt it. How can it be written into this? How does this work?
Ok so, this is my purpose: - to be able to load asynchronously (via AJAX) some javascript ads (like google's or adbrite) so as to make them be loaded in the background, then update the page after the ads have loaded via innerHTML
Why? -Because 90% of the time in my newer sites, javascript ads are the major offender in terms of speed of page rendering
My problem: Via ajax, I can call a php file that retrieves some javascript and outputs it, XMLhttprequest returns those javascript lines, but they don't render in the page, since they miss the whole page loading, and are apparently not parsed For example, let's say I call a php file via ajax, and it returns the output into a variable named "text" containing "document.write('hello')" if I use xxx.innerHTML=text, nothing happens
My 1st solution: Passing those javascript lines to eval() [like eval(text) ], but this produces a second problem, that I couldn't solve (probably because of my lack of knowledge in javascipt): if I eval the code, it deletes my current page and renders a new one for example, if I parse a document.write, my page disappears, and a new one is rendered with the document.write text
What I want is basically to make that "document.write" appear inside a div in my page, adding to the content (and not overwriting the whole page), much like what happens when using innerHTML
Is this even possible? How would you go about it? I tried xxx.innerHTML=eval(outputfromphpfile) but it overwrites my whole page...
Just a quickie: is it possible to place javascript within javascript? The following is the code I am using to create a pop-up for a picture gallery. I would like to place a banner from a banner exchange in bold under each photo. When I use the code below I get an error message:
Basically, on one of my sites I'm running adsense and today I added Chitika. The problem is, I can't run those type of ads through my banner advertising program.
The banner advertising program calls the banners/HTML from code like this:
And using that program I'm able to either choose a banner or HTML I want to display when that code above is used. It displays HTML ok... but when I try to run an ad of either adsense or chitika nothing displays on the page. The code that would be called is:
So... it looks like I can't have javascript call another javascript to display on a page. My question is then... how can I edit the above to make it work or how can I work around this problem? I'd really want this to work with Chitika and not so much with adsense... but it appears both Chitika and Adsense use similar javascript code.
