JavaScript - Cross Domain Scripting.
Hello,
I am trying to create an imageuploader for my forum hosted on domain forum.com (fictional domain name) The image uploader is hosted on domain uploader.com (fictional domain name) When the uploader is done i want info to be passed from the uploader to the texteditor on the forum using javascript. I tried everything i could think of with document.getElementById but to no avail. The element on the forum is clickableEditor.textarea Is it possible and if so, can someone please help me out? Similar TutorialsJavaScript code is not traversing via Iframe with Cross Domain. Actually i was assigned with a project, to grab the top page URL, which has many Iframes, which are coming from different domains. The final sub domain has the JavaScript code, which has to grab the top page URL. Can anyone help me out in this???? Hi, I have searched and searched... Is there a way of using the Ajax httpRequest cross domain? thanks Hi All, I'm writing this post as there are alot of questions about Cross Domain AJAX request so i'm going to give an overview of the different ways and the best practices Ok so there are 2 systems for this the key difference is how much control you have. If you control the Requested site you can use Javascript Safe calling to that server, this is all done via a few Headers so to do this all you have to do is send some headers from the page your requesting. The first is tell the browser that the site the AJAX call is coming from is allowed this is done with "Access-Control-Allow-Origin: " Now this can be set to a wild card and allow all sites to access the page "Access-Control-Allow-Origin: *" Or you can say only a set server can "Access-Control-Allow-Origin: mydomain.com" This header allows GET requests but what if you need to post data to the site well you need to tell the browser that POST data is allowed to be sent Access-Control-Allow-Headers: GET,POST Now we run into the problem that sending post data the browser will send the header Content-Type but your server has not told the browser its allowed to send that header so Access-Control-Allow-Methods: Content-Type Will allow the header to be sent if you wish to send any other custom headers you have to make your server tell the browser its allowed to send them this is done by adding them as a comma delimited list via the "Access-Control-Allow-Headers" header Now if you dont have control well then your back to using a script that is local to the AJAX script then sending the data via cURL or another connection method to the remote server Please note i will be uploading examples in php later. Example Scripts Remote Server PHP Code: header("Access-Control-Allow-Origin: *"); header("Access-Control-Allow-Headers: GET,POST"); header("Access-Control-Allow-Methods: Content-Type"); $output = array( 'response' => 'hello world!', '_GET' => $_GET, '_POST' => $_POST, ); echo json_encode($output); Client Script -- please note built for Google Chrome PHP Code: var getExample = new XMLHttpRequest(); getExample.open("GET", "http://www.test.com/remote.php?test=set", true); getExample.onreadystatechange = function(requestHandle){ console.debug(requestHandle); } getExample.send(null); var postExample = new XMLHttpRequest(); postExample.open("POST", "http://www.test.com/remote.php?test=set", true); postExample.onreadystatechange = function(requestHandle){ console.debug(requestHandle); } postExample.setRequestHeader("Content-Type", "x-www-urlencoded-data");// this is sent to prevent the requested server not saving post data postExample.send("?set=test"); If you are unable to Edit files on the remote server you can use the link provided by Kor http://www.troywolf.com/articles/ This will give you all the information you require to use php to talk to the remote server (basic proxy in effect) hi, my working project (needs a proxy): http://www.mypubspace.com/dashtest/order.html currently working through this tutorial, I have setup a proxy and saved it as proxy.php http://www.wait-till-i.com/2010/01/1...query-and-yql/ I just need to put this piece of code in my JavaScript but not sure where?! Code: var url = $(this).attr('href');
if(url.match('^http')){
url = 'proxy.php?url=' + url;
}
here is my project code Code: <html>

Hi guys. I want to create login form similar like facebook login which web owner can put the script and it will become login for their web and also it will auto register at their web. I believe it need to use javascript because javascript is cross platform. Can someone give me a clue for me to start on? I read the "http://bodybrowser.googlelabs.com/body.html" page into an Iframe on my page. I now need to print the "viewcontainer" DIV that resides in the iframe. Accessing divs in an iframe is an issue with cross domain sources. Can anyone help me with a workaround or different idea? Thanks in advance!! Anyone know if there is a way to get the title string from an iframe src coming from another domain?
Hi, I'm currently developing an application (in php) for a website that is to be integrated into their website using iframe. It's imperative that it's done using iframe as I am placing the application on my own server. In short, the iframe element appears on my customer's website (lets say customer.com) - something like this: <iframe width="440" height="500" frameborder="0" scrolling="no" src="http://www.myserver.com/index.php"></iframe> However, it's quite imperative that my application (i.e. what's located at myserver.com/index.php) only can be shown in iframe elements placed at customer.com. That is: I want to make sure that a similar iframe element from another web server (lets say anothercompany.com) has the possibility to iframe my application located at myserver.com. My first idea was to check this using php in my application: by looking at HTTP_REFERER, I can get the location of the page containing the iframe element. That solution seems to work fine. However, as is well known, it is possible to spoof and even hide the http_referer server variable. Still, as I only want to make sure that no other server accesses the application through an iframe object, it should perhaps be an okay solution - if someone wants to access the application from their own browser, and spoofing the HTTP_REFERER variable, I'm fine with that. (I just want to make sure that only customer.com, and not anothercompany.com, can integrate the application with an iframe). The other thought I had was to use javascript and DOM stuff. The idea is then to use javascript to check that the application has a parent frame and that its location is at customer.com. However, as we are dealing with two different domains here, I'm having a lot of problems getting the document.parent.location variable - it's not allowed! Any solutions on how to do this in javascript? Any way to bypass the obstacle above? Or perhaps javascript isn't the best way? My guess is that there is a solution out there somewhere - I guess there are a lot of ads that are integrated into various websites using iframe, and where the actual content (i.e. what's inside the iframe element) can check which server is embedding the ad through an iframe element. I've been working on a site where the content is displayed in an iframe. The iframe content is on a different domain than the iframe itself. I've already got around the cross-domain problems by creating a file on the parent domain that the iframe content references via another iframe. (which uses parent.parent to skip the permissions issue) That was all fine and pressing back and forward in the browser navigated back and forward in the iframe (at least in FF, not 100% sure about other browsers) Then the client wasn't happy that the url in the browser didn't change and pages couldn't be bookmarked. So I created a solution where the parent.parent.location.href was changed to be domain.com/#/path/to/iframecontent.php so that pages could be bookmarked, that works fine but now back and forward don't work, or more specifically the url changes correctly but the iframe content doesn't go back. I'm facing an issue with fetching the page URL from an IFRAME with cross domain. Is there any approach/ any ways to achieve this? I'm wondering if anyone out there has a jquery solution to using an iframe that automatically adjusts it's height of the child and also works cross domain. Any help would be greatly appreciated. Hi there everybody, I've got this problem which I can't solve myself... I've got a website which has 3 colums and is hosted on domain1.com. in the right column I've got an Iframe which loads content from domain2.com . this content are some textboxes and a datepicker tool. if I press the 'search'-button in this Iframe I would like to refresh the mainpage (from domain1.com) so that another Iframe appears in the middle column. in this column i would like to load a new form from domain2.com which contains the values that I've put in in the form from the right Iframe. Unfortunally I can't get this to work... Will somebody please help me? Hello, If i use this to protect myself from XSS scripting, do you think that it will be enough? http://www.hscripts.com/scripts/Java...e-html-tag.php Thank you. Can someone not just block this script, by banning javascript.? Hi guys, I'm trying to work on this code to make transportation an additional option when adding a reservation at http://morningstararuba.com/reservat...servation2.htm. But there must be some errors, I included part of the code, because it does not activate the selection box. Appreciate your help, thanks! Code: <tr> <td>Champagne:</td> <td><select name="champagne" size="1" disabled tabindex="16" onchange="javascript:total_cost(passangers,charter_request,champagne,cost)"> <option selected value="None">None</option> <option value="Freixenet">Freixenet</option> <option value="Veuve Cliquot">Veuve Cliquot</option> <option value="Veuve Cliquot Vintage">Veuve Cliquot Vintage</option> <option value="Moet Chandon Brut">Moet Chandon Brut</option> <option value="Moet Chandon Brut Rose'">Moet Chandon Brut Rose'</option> <option value="Moet Chandon Rose' Vintage">Moet Chandon Rose' Vintage</option> <option value="Dom Perignon">Dom Perignon</option> <option value="Dom Perignon Rose'">Dom Perignon Rose'</option> </select></td> </tr> <tr> <td>Transportation:</td> <td><select name="transportation" size="1" disabled tabindex="16" onchange="javascript:total_cost(passangers,charter_request,champagne,transportation,cost)"> <option selected value="None">None</option> <option value="Bentley Roundway">Bentley Roundway</option> </select></td> Quote: Hi, below code is only working in Firefox but not in Internet Explorer. Once I select YES from drop down list, then the next text box should be greyed out and the second should show value 10. This works in Firefox but not in Firefox . Code:

Dear Forum, I have a website of quite a few pages which also has a style sheet switcher so the user can select their own customised graphics and layout (css file) these css files load in the graphics but only when the call is clicked... even if the page has already been opened for seconds or minutes when the graphics could have been loaded in for an instant switch. so i implemented the following code: Code:
<SCRIPT language="javascript">
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
</SCRIPT>
<body onLoad="MM_preloadImages('/corporate/heading.png','/creative/heading.png','/earth/heading.png','/under-the-sea/heading.png','/space-and-stars/heading.png','/classical/heading.png','/corporate/document.jpg','/space-and-stars/document.png','/creative/document.jpg','/earth/background.jpg','/under-the-sea/background.jpg','/classical/document.png','/classical/background.jpg','/under-the-sea/document.png','/corporate/home-graphics.png','/earth/content.jpg','/earth/footer.jpg','/earth/home-graphics.png','/under-the-sea/home-graphics.png','/creative/home-graphics.png','/space-and-stars/background.jpg','');">
it works fantastically - you open the page and as long as it takes to notice where you can click the styles is the same amount of time it takes to have the styles cached for the styles switch immediately and effortlessly. however, the site has grown and is now quite a number of pages with the above in each html file. ive just added a "creative 2" style, which has caused the above to need updating........ the maintenance of this code is inefficient to edit each page. would someone be able to point or show me how to, in principle: Code: <body onLoad="MM_preloadImages('/styles-code.js);">
styles-code.js?? page:
'/corporate/heading.png',
'/creative/heading.png',
'/earth/heading.png',
'/sea/heading.png',
'/classical/heading.png',
'/corporate/background.jpg',
'/creative/background.jpg',
'/earth/background.jpg',
'/sea/background.jpg',
'/classical/background.jpg',
etc
and have 1 page of this code called in by all pages in an easy to see and edit list? would really appreciate guidance with this, I want to have a real time text ticker. I would be able to type something in and it would continue to scroll until I typed something else (followed by the return key), and it would scroll that, without the end-user having to refresh their screen to see the update. I was hoping their might be a script out there already that does that, but since I can't find one, I thought I'd see about trying to create one. What would be the most practical scripting language to use? Or if you know of something that does this already, could you point me in the right direction. Issue 1 - Solved I have this workbook with multiple sheet. I need that the data from the mail sheet gets sorted to the other sheets based on the value in certain cells. https://docs.google.com/a/housing.co...it?usp=sharing IQT 3.0 is the main sheet The condition to copy the data is simple based on data if available in column I to N then the data in that full row should get copied to the sheets with the same name as these columns. multiple entries is possible if you look at the test data Row 2 has data available in 3 columns i,K&L now all the relavent data should get copied to the sheets with the same name as these columns & the data should go under the appropriate columns in these sheets. Issue 2 - Pending Need Help Each error sheet is worked upon by different teams is there a way to ensure that the status of the project in the main sheet cannot be made live till all errors for that particular project have the YES selected under Resolved & Passed by QC. If the Resolved & Passed by QC. are YES for each error in a particular project only then can the status in the main sheet be changed to LIVE & highlighted in green else it should show the status as PENDING only no colour. Once the Status is live then the project should be moved to the archive sheet & also removed from the error sheets so that the only projects visible are the ones pending to be resolved & sorted by process date. also need to ensure that no one except the sheet owner can delete the code or the sheet. |
