Some times the PHP server that hosting my site become down, while, the server still executes the html and JavaScript. I am looking for a method that resolves the response code of a page (e.g.: 404, 500) and redirect the user agent to another url. Can JavaScript help me in this case?
View 2 RepliesI am creating a new Web site and want the forms checked by Javascript before the data are submitted to the server.
I am using the same Javascript code that I have used for this purpose, but for some strange reason the Javascript is NOT firing and instead the form is submitted to the server before client side Javascript checking is done.
You can see the page under developmet here:
dreamdates.com - TOTALLY FREE online dating service - date singles ready for romance and love
For example click on "Sign Me Up" button without filling some form inputs, you should get Javascript alert message about forms that have not been filled yet, but that does not happen and instead the form is submitted to server!
The scenario is of two different web servers. The parent frame (html
page orginates from server 1) has script like
function x1()
{
.....
alert('parent invoked');
....
}
Inside child frame (html orginates from server 2) the html refers to
parent script like
{
.....
parent.x1();
....
}
It throws Microsoft Jscript runtime error: permission denied. I am
using IE based on WinCE 4.2 version platform.
I am writing one iframe dynamically from my code like below. document.write("<iframe src='" + location + "?querStr=" + querStr"' width='0px' height='0px'></iframe>"); location is something like - [URL] and the querStr is some parameters passing to the iframe. querStr contains some parameters which have timestamp appended. So the request url is always unique. In IE/FF2 i am seeing proper unique request (200 response code) but in Firefox 3, the url is getting cached. From my code (before sending the request) i can see proper generation of the request but actually the request url gets cached. I saw it using fiddler and the response code is 304.
View 3 Replies View RelatedI'm having problems performing a simple load(...) request to bring in HTML content from a partner Oracle system within the same domain. Our portal has a built-in SO connection will handles security for me transparently. However during the process it initiates a 302 temporarily moved response which seems to trip up an AJAX request, but doesn't trip up Firefox when accessed through the address bar. If I use the same URL in an IFRAME it's totally fine.
After tons of googling, searching the forums, and the bug tracker database I cannot find anyone who has experienced this problem. Before I open a bug ticket I'd like community feedback to help me see if I am doing anything wrong.
My AJAX call looks like this in Javascript:
$.ajax({
url: "someurl.php",
success: function(data){
//..process on success..
},
I want to reload the page if session is timed out so I am checking the user session at PHP file and if session is timeout I am sending error code. if I get the error code in response I will reload the page so that it will load login page.
I have an html for that when a user clicks the submit button it will
run a remote cgi program and based on the response do one of two
things.
1. If the response contains "OK" continue the form submit.
2. If the response contains "NOGOOD" Cancel the submit and return to
the form.
Some servers return JavaScript as the response to an AJAX request. When
the response JavaScript is eval'ed it calls other JavaScript functions
already in the browser to update elements, etc. This seems like a good
system because it allows so much freedom in creating the desired
behavior in the browser. The required data doesn't have to be converted
to XML or JSON on the server. The browser doesn't have to have
templates for interpreting and converting this data into some change in
the browser. All of the conversion algorithms don't have to be written
and changed when new behavior is required. This remote procedure call
approach is the predominant system in the Ruby on Rails world.
(Unfortunately they are calling Prototype.js functions.)
However apparently some people seem to think this remote procedure call
approach is a bad idea. I can't see why it is so bad because it is so
lightweight and flexible. It also helps to keep the client less
intellegent which seems good in a world of incompatible client-side
bugs.
If I use some neutral data format like XML to accomdate different types
of clients then I have to write different client-side interpreters for
each type of client (browser, RSS, POP, cell phone, etc). Why not just
write different server-side code that generates the correct JavaScript
(or other) for the requesting client type?
When is the RPC approach such a bad idea?
I have managed to succesfully post the data to the php page... (i can see using firebug that it IS being sent) but i get a message Quote: Apache HTTP Server has encountered a problem and needs to close and the response is empty... what am i doing wrong?is possibly something to do with the space in the value of the options?
Code:
<head>
<title>Auto suggest</title>
<script src="ajax.js"></script>[code].....
In my browser, I make an AJAX request. The server sends me a fragment
of an HTML document. That fragment has some JavaScript inside some
script tags. How do I run these scripts when the fragment arrives at
the browser?

I would like to know how to write javascript such that, a part of it isnt considered as script, & rather as HTML. Code:

I am working on a piece of code for an academic experiment and it
puzzled me for days, any help?
I use javascript to sort a table in a html page. bascially, a user can
click on any attributes and the javascript code will rank the contents
of the table based on that attribute. This is done.
Now I want to record the click information into an access database.
basically, wheneve the user click an attribute, I want to use asp code
to insert the click information (userid, attribute_clicked) into an
access database.
My current solution is use window.open in javascript and in the open
function, I insert the url of the asp. something like this:
var nW = window.open('', 'newwnd', 'width=0,height=0,left=0,top=0');
nW.location.href = "desc.asp?subjectid="+ subjectid + "&item=" +
attributeinfo;
nW = null;
However, the problem is there is always a popup windows appears when
the code was executed.
What i want to know is if there is anyway to let the asp code running
in the background invisibly by user?
I have copied from a site a javascript code for my web site to create a
pop up. This works fine on older versions of browser but not the most
recent. Whilst I have been searching for some new code to replace the
old code I have also learnt that the javascript will not always work
as it may not be enabled.
Therefore does anyone have some code that I could copy that will work
fine on all browser and if the javascript is not enabled.
I am looking at doing a asp.net web-page in VB code with java-script as well. I want to pull the information from the database(SQL server or Access) and then feed that information to my java-script code. Is that the way to do it or can you do Access or SQL in java-script pretty easy?

I need to add some javascript code block dynamically to a web page.
I looked into the various postings at various groups but none seems to
be solving my problem.
Among the approaches suggested first one is to create a script element
and set its properties (src etc) and then adding this script element to
the head element.
This works good for a dynamically including the files. But, in my case
I do not have any files but generating the content dynamically which
should be available to other javascript functions in the page. The
script that I need to add dynmically is given Code:
AIUI, it was not all that long ago when the threat to personal users,
was attachments that when executed compromised machines with keyloggers,
trojans, etc.
Now it seems that the big problem is reading a webpage or an HTML e-mail
and getting affected through the scripting. My understanding is that
the script downloads the malicious program from the web and sets it to
run on start up through the start-up folder or in the registry.
I don't know much about this; can someone suggest a good web site to
start learning a bit more about these threats. I have googled, but I am
not quire sure of the best search terms, and since there is so much
information out there, a site that experienced people endorse would be a
lot of help.
In particular, it seems as if JavaScript dowloading a trojran without
the user clicking an attachment is a big problem.
Any one knows how to encrypt javascript code... other way than escape()
and unescape() [not is encrypt but a way to protect source code ????
if speed, size is not a matter, i just want to protect the code as much
as possible, any library or tools do you think is the best solution
right now?
i know there is not a perfect solution, but as good as it can be is
okay...
p.s. need to be cross brower.
Is there any documentation or reference for the Mozilla web browsers.

Should I code for users without javascript? I don't know of anybody who doesn't have javascript turned on, but I have seen stats that say users without javascript run as high as 10%. I went to music.yahoo.com, I saw that they didn't code for no-javascript users, leading me to believe the no-javascript is a highly rare group.

I've been trying to do this for days without success. Is there a way to open a popup window from within the php code? Example:
if (some_condition) {
open a popup page and load a file in it
break;
}
As we all know, JavaScript is client side and php is server side, (the php
code is 'allowed' to do stuff on the server that JavaScript cannot).
The problem with php is that it timeout after a while, (and the user also
has no clue as to what is going on for a long time).
I need to run a script on the server that could take a very long time.
So what I was thinking is mixing both JavaScript and PHP
Something like,
<script>
var endvalue = 1000; /* some number that the server can calculate
quickly */
var i = 0
while (i<=endvalue)
{
/**
call a php file that will do some work
somefunction.php?someNumber=i
*/
}
</script>
That way the server does the work, while the client keeps it going.
Ideally I would also get a return value/string from the php script.
