I want to populate my client's webpage (Remote Server) automatically
through my Server and Database by having him just paste a javascript
on his webpage.
I have read up about Microsoft Remote Scripting but the documentation
states the following : "The server which you make remote scripting
calls must be the same server from which you requested the client page
containing the requests."
In my case , the client and server pages are on two seperate servers
which means that I cannot use MS Remote Scripting.Is there an alternate
approach in any scripting language ???
Any suggestions, tutorials , websites , code snippets will be
appreciated while i continue to research on this...
I have a few values and variables that I want to post to a server (without using a SUBMIT button). Is there a way to post data from within javascript - do sockets or connections have to be open for this to work?
I am hosting my website in free server (freehostia.com) and i am using joomla1.5 . I want to parse RSS from my other websites. Joomla does it with its modules. But the server do not allow outbound HTTP request, hence i had use rss-to-javascript website to parse RSS feeds. It parses well but there is its advertisement below the feed (which i think is nonsense).
Here is what I am trying to do. On my web page, I have three choices for the user to pick from. After the user selects one of the checkboxes and clicks a submit button, I need to send a http request to a remote server to record the user's choices (actually it is an https that I am sending),.. so I need to send something like this.
[URL]
The remote server responds with an xml response that looks like this:
So, I want to post the request, read the response (answer) back from the other server and display it on my page. So, my dilemma is as follows:
1) my understanding is that I cannot do this with AJAX using an XMLHttp object because it is on a remote server and it would violate some sort of same-domain security. Is that correct? If in fact I can do it in AJAX, how do I read the response back from the other server?
2) if I am correct in my assumption in 1) then what is the best way to accomplish this task?
I'm building a very simple app that relies on a remote server. I will use this app on many websites, so I decided to store it on one server (I have control of the remote server in question).
I need to make sure that this server is up and running, so in the case it's not I can use a fallback.
Would it be a client-side approach? A server-side approach? My guess is to use a js snippet to do the job. If I'm correct, I'll probably use jquery to perfom the task.
I am developing extension which should upload currently displayed html as a file to a remote web server, unfortunatelly so far i haven't suceeded. I think this should be done through XMLHttpRequest(), but neither I know how to upload files through XMLHttpRequest nor how to convert string to file.
The HTML form that uploads a file:
But as I said i need my plugin to do it automatically and file must be made from html code.
I have a drop down menu with a change event that makes a JQuery JSON AJAX request, which I've simplified for this post:
Code JavaScript: $('#id_template').change( function() { var data = { action: 'change_template'
[Code]....
When I do change the drop menu's value, the request seems to be successfully sent with a successful reply received (inspected it in Firebug), as the content in the "status == success" is accessed. However, the problem is the response is null.
I don't have this problem when I'm testing on my local WAMP setup, and so have no idea why everything appears to be working fine here except the retrieval of the response array.
I wanted to ask how it is possible to get error messages from the server till it is implemented in the remote method.What do you think is the less work intensive alternative.I also wanted to ask if i have two fields A and B, and the values of B depends on A. How do i make it with the plugin and the remote method ?I saw that there is a way of writing custom methods:URL...But how do i combine it with the ajax calls?
I'm trying to read a file (will be a firmware update) into a byte array or binary stream or stream of some sort, and then POST it to my server. Any suggestions on opening and reading files from within js? Note, the server is a development server and will not run PHP or CGI scripts for example. I just need to be able to open a file from within a js function.
Also, no ActiveX objects, this needs to be Cross Platform.
A newly added, not-quite-wanted function of my job is remotely debugging JavaScript errors on other people's web applications. I have tried finding a JavaScript debugger that would allow me to do that, but other the Microsoft Script Debugger, I couldn't find any other.
Are there such programs? Basically, what I'd like to be able to do is trace commands step by step and view the values of certain variables.
I was unable to figure out how to get Microsoft Script Debugger to work. I read the documentation and executed it, but I keep getting "Syntax error" messages whenever I want to see the value of a variable. Add to that the fact that I am not a developer and I do not know JavaScript (other than to read it, which is enough for me to figure out what the problem is) and you see my problem.
I have read about the option of adding message boxes all over the place, but this would not work out for me either, since I would need to make changes to this code on the web server, where I don't have access, and it would be a lot more tedious.
For those skeptical as to why I still expect to be able to debug problems:
The problems are caused in most cases by the proxy we add on their web servers, and they are due to values being changed on the fly. I only need to find out where the code breaks and read the values of the variables, which gives me the solution ("do not change this variable").
I am trying integrate an upload system from YouSendIt.com in to my companies forms. The code they give for integration is basically an iframe with a coded URL set for the source. Their server sends a postback using HTTP Post method but I am not sure how to access the data that is sent back. I do not need to display it but I need to use it for validation purposes in the rest of my form. The Iframe code is as such:
I'm trying to use a remote file for the purpose of setting the value of a single variable. It contains a single line of code: var rev_date = "R10-03-07";
In the HTML, it is called like this: <script language="javascript" src="http://some.domain.com/revdate.js"></script>
There is a function in the head: function setRevdate() { document.getElementById("revdate").innerHTML = rev_date; }
In the Body: <body onload="setRevdate();">
Then where I want to place the text: <span id="revdate">--</span>
The problem is that the page loads and the onload event seems to happen before the rev_date string object is created and produces a "rev_date not defined" error. If I hit the browser refresh, however, everything works fine and the text is displayed between the span tags. It continues to work thereafter as long as the browser session is not destroyed.
How can I program this to force the browser to wait for the script to be read in and the variable initiated before calling the function?
I'm not sure what this is called, I think it's remote script execution, but I could be wrong, so bear with me.
I have a call that I make for an adserver:
<script src="http://www...."></script>
That populates the page at that point with some text. When it works, it works great, the text comes back, and everything is good. However, when the remote server does not return right away, or maybe the connection is down, my page hangs on it.
So my question is, is there a way to structure the call on my end so that my page continues loading even if this call doesn't return?
When I try to parse xml fixed string following code works fine. When I try to parse the string get from remote server.(bellow code example) It gives me an error unterminated string. I think this error is because of large string. Code:
I have created an entry form that I display in a modal dialog. I have two buttons on the form: "Add and close", and "Add and allow me to add another". However the only time my modal form will post back to the server is after the form has been closed. I want to do the following: The user opens the form in a modal dialog. The user enters data, and clicks the "Add and allow me to add another" button. The page sends the user input to the server, which adds the input to a database and updates a datagrid on the page. This updated datagrid is visible behind the modal form, so the user can see it happening in the background The form clears all input fields and the user goes again. Any code I write that calls the server (button click events, ajax calls, etc) are ignored, unless the modal form has been closed.
However, this piece of Javascript uses some other script which is large.
<script src = "./js/tmp.js".....>
This will work if the file "tmp.js" is local. However this reduces the portability of my *utility* Javascript as users have to have that "tmp.js" for every webpage they have (if they want to use it :D)
I thought of uploading "tmp.js" it to somewhere and change my code to
I'd like to implement a server socket in java: something linke the following example.
The problem is that the HTML has not the permission to execute instruction serverSocket = Components.classes["@mozilla.org/network/server-socket;1"]. createInstance(Components.interfaces.nsIServerSock et);
Question:
1 - how do I give it this permisison?
2 - one solution I thought was to put the javascript code in a firefox extension, to load, so it should have all needed permisison, but, How can I call a java script function define in an extension from an html page? - there's some particular syntax? ....
I have three different web pages with different domains, and I want to show some pages of one of the webs in the others.
I use an iframe for this and it shows it good until I have to call a javascript function in the iframe inside page, I have a permission denied because the domains of these pages are different.
So, the cuestion is:
Is there some way to call the javascript function of the iframe from the parent page?
I might be turning a corner today and seeing the light. I might still be confused :)
If JavaScript is the language for the browser then why do servers use Ruby/Rails, Perl/Catalyst, Python/Turbogears or PHP/Cake? Is it because the prototype-based language is too different to be chosen except when necessary. Is it because browser bugs make people think JavaScript is bad? Is JavaScript not suitable for the server-side for any reason?
I imagine that if server-side programmers started to learn JavaScript then the client-side code in the world might start to improve. Translation layer libraries like Prototype.js or Mochikit wouldn't need to exist. The more I learn about JavaScript the more I like it. It is difficult to learn however for multiple reasons.
I have seen web pages sites, when you drop down a list box, it seems to go back to the server to retrieve some data without reloading the whole page (e.g. select make of car and it retrieves a list of models from the server to populate another list box).
