I have come to my whits'-end looking for some code to update a layer with a timer, with data from another page.
I know this is possible, I have seen it before, but wouldn;t have a clue where :'(
Has anyone done this before, or could someone point me in the right direction?
I currently have a form that asks for certain info. When the user enters and then submits it, a javascript script sends the info to a php form and then php does its thing. While doing its thing, php tries to change a php session. I am wondering if there is a way to change the php session, and have it take effect on the user end without a refresh. So if the user has a session for their name (Bob), then goes to this form and changes it to Joe, then session the user has will be changed from Bob to Joe without the page reloading. Is this possible?
View 1 Replies View Relatedwhat I have is a code containing 2 iframes inside a div.what I'd like to do is refresh one of the iframes when it's page recieves an update from another user.
perhapse I could load the page on the document load, and store those contents in a var.then have a code that will compair the remote page to the var every second or so.if the page compairs differently, update the var info and refresh the iframe.
we are developing an web application. In this user has an option to comment or mark a video. After user commented or marked it has to shown automatically on the page with out refreshing the page.
View 1 Replies View RelatedI'm working on a project which requires a small portion from a large table of information to be displayed on a webpage (sort of like a magnifying glass). The display will be a table of fixed size (m by n cells). Some of the cells will be merged. When the table updates, different sets of cells may be merged.
It needs to be coded in HTML5, which I assume includes the use of JavaScript and CSS (The specs of this is rather unclear at the moment, so I'm going to cover all bases).
Anyhow, looking through the HTML5 and JavaScript tutorials, I found two ways to solve this problem. One way would be to have a script to parse out the relevant information, and have it output into a table (dynamically generating the HTML required).
The second way would be to have the script draw the table on its own in a canvas.
User events (such as arrow keys on the keyboard) will change the position of the focus (move the magnifying glass in a cardinal direction).
I hit a small snag with the first solution - Is it possible to update the table on the page (including changing the structure of it) without having to refresh?
In my jsp,Struts project i am using the javascript calendar control for selecting the date and by using function calcage() i am calculating the age of the user but problem occurs when the page refreshes OR when user updated the other values such as name ,contact no. Then the value of the age is set as 0 in the textfield as 0

I looked at this script and I tried playing around with it but could not figure out how to: Instead of having a check box field and then a radio box field, have 2 radio box fields, so the user picks from one group of radio boxes and then another. Then change the math behind it so the values in the first field are multiplied by 100 and then the values in the second field tack on a percentage (ex value in first field is 1.5 so 1.5x100 = 150 and value in second field is .5 so total is 225).

If a news post (thats what it is getting from the database) is deleted it will continue to show the same information. I can't really post all of the script because it (along with the html and php) are spread out through many different pages:

Layer writing in Netscape. This is pretty straightforward >> However I'm trying to write to a <div> layer within a <div> layer.
My div:

<div id="blah">
<div id="aight">

I'm trying to write to "aight"
How should my code look?
I have created a floating layer using Javascript that remains always on top of page on scrolling.Issue is,at some point while scrolling,the layer flickers continuously.
The html page is as follows:
Many common software systems, JavaScript has a history of security problems. Many of these problems could allow a person with malevolent intent to steal sensitive information from a visitor. The number and type of such holes in security vary among browsers and operating system versions. Most JavaScript security holes have been caught and fixed, but new ones are being discovered all the time. For a list of current security holes check out your browser's and operating system's Web pages. As a Web site author, it is your responsibility to keep up-to-date on the current status of known security holes in the applications you create.
Signing Scripts. In Chapter 11, I explained that JavaScript does not provide the ability to directly access files on the client computer. This can be a very large hurdle to overcome if you're trying to upload a file to a server from the client computer. Fortunately, file uploading is one of many functional enhancements that signed scripts provide. Signed scripts are specially packaged scripts that have been verified and signed to be correct and non-threatening. These scripts have additional rights on the client computer that allow a programmer to do many things that he wouldn't otherwise be able to.
With the introduction of Netscape 4.0, a new security model was put in place that would allow digitally signed scripts to bypass some of the restrictions that had previously been placed on them. A signed script can request expanded privileges from the visitor and, with the visitor's permission, gain access to restricted data. A signed script requests these additional permissions through LiveConnect, which allows your JavaScript code to communicate with the Java Capabilities API. The security model allows JavaScript to access certain classes in Java in order to extend its functionality while still maintaining tight security for the client.
A digital signature is a fingerprint of the original programmer, and it allows the security model of the browser to detect where (or from whom) it originated. A script signer can be a person or an organization. By signing a script, you acknowledge yourself as the author and accept responsibility for the program's actions. A signed script contains a cryptographic checksum, which is just a special value that ensures the signed script has not been changed. When a digital signature is detected, you are assured that the code has not been tampered with since the programmer signed it.
Once you finish writing a script, you can use the Netscape Signing Tool to digitally sign it. Signing a script does the following:
Unambiguously assigns ownership of the script to a person or organization.
Allows an HTML page to use multiple signed scripts.
Places the signed script into a Java Archive (JAR) file.
Places the source of the script in the JAR file.
Once a user confirms the origin of the script and is assured that it has not been tampered with since its signing, he or she can then decide whether to grant the privileges requested by the script based on the validated identity of the certificate owner and validated integrity of the script.
JAVASCRIPT FILE IS AS FOLLOWS:
AND CSS FILE IS AS FOLLOWS:
At some point while scrolling,the div 'movable' flickers continuously,while at some other point,it is perfectly stable.
the page url is
Code:
`http://example.com/index.php?main_page=index&Path=<?php echo $_GET['Path'];?>`
there are some contents on the page:
[code]...
I have this code in a page that appears in my iframe if requested from parent:
<script type="text/javascript">
parent.rrr();
</script>
The parent code is:
function rrr() {
javascript:location.reload(true);
}
So, the person clicks a link from the parent, it does a php process in a hidden iframe, which then tells the parent page to refresh. The only problem is that it puts Firefox in a constant loop of refreshing. IE and Chrome work fine. They refresh once and stop.
Though the src code opens the iframe like so: <iframe src="" style="display:none; height:1px;" name="hdplus" id="hdplus"></iframe> Firefox seems to refresh the page with the memory of the child page being in the iframe, constantly looping the child request to refresh the parent.
Why won't Firefox just accept that no page should load in the iframe, as stated in the code? I need to stop this loop, which means I need to get firefox to reset the iframe as it reloads the page.
How to refresh DIV , without refresh entire page,Am having four DIV ,
DIV1,DIV2,DIV3,DIV4
I want to refresh only DIV! without affecting the DIV3,DIV4 ,
I have the below code:
<script type="text/javascript">
function loadQuickMessageCheck(File,ID){
var xmlhttp;
[code]....
So my problem is that i can't send form data in FF without page refresh (though in IE7-8 everything works smoothly).
My code fragments:
I am trying to make a banner the size of the with of my screeen, in
a layer.
BUt I also want to fade it to a complete transperency to reveal the contents
of what's behind it (my page ofcourse) and possible close or hide the faded
layer.
I've seen stuff like that happen in a flash everonment. I was thinking about
using a transition at first to go from one page to another with an
introductory page.
But I rather have everything on one page and just fade the introdutory layer
into the page. Is that too much work for jscript?
I have a strange behaviour when applying onmouseout to a layer. it is
not trigged when the pointer goes out of the _layer_ but when it goes
off the _text within_ the layer.
I want to create a layer that 100% wide, 200 px high and stays at the
bottom of the screen, even when the page is scrolled, how do I do this?
I have seen it on websites but can't find any example code ...
Can someone please tell me how to print a single layer?
View 3 Replies View RelatedI have written a javascript routine that populates a parent document
with a series of <iframe>s. Each <iframe> receives its contents from a
series of separate smaller HTML files. Of course my NN 4.8 browser
doesn't deal well with the <iframe> so I wrapped the code that generates
the <iframe> in <ilayer> tags. NN now recognizes the contents.
However within each of the 'content' files I have another javascript
routine that basically displays the file name (via document.URL &
document.write) of the content file. My IE 5.5 & Mozilla 1.5
understands this perfectly. However my NN responds to the document.URL
with the wrapper/parent document's URL, not it's own unique file name.
I've named/ID'd the iframes & ilayers. If the document.URL fails I can
still make use of the ilayer ID but I need to know the index into the
layers array. I can hard-code a index value into the
document.layers[x].name but given that the position of the particular
content file is dynamic within the parent, the index is going to be
wrong 9 out of 10 times. There doesn't seem to any way for an i/layer
to know who it is Code:
I want a scrolling JS layer (not CSS) am trying to fit it into an already existing site design which the client doesn't want to change. It works fine when i try it on a new page but the moment I put it into my actual page where it has to fit into a particular are (I used the overflow: hidden it doesn't behave!!
View 13 Replies View RelatedI've got a web page which uses lots of divs to position the content of the

I am using javascript to open a new window like this:
printpreview=window.open('printview.php','printpre v','width=600,height=600');

How do I refer to that layer?
I have an image on a web page within a css layer:
<DIV ID=MyLayer
STYLE = "position: absolute;top:68px; left:563px;
width:640px;height:480px;">
<IMG src="ReportImageBox_12.54.52.png" width=640 height=480></IMG>
</DIV>
I need that the parts of this layer which have a certain color
(for instance "white") be rendered transparent.
My question. Is it possible to have a simple javascript function
to incorporate in the web page which does this?
I was wondering if it was possible (and if so how) to put a layer ontop
of frames. What I mean is that I would be able to put anything,
including tables ontop of frames so that it could go ontop of two
frames at once, independent of everything else.
Also if it is possible, how would I make it stay still, evenwhen the
page is scrolled... like so that it doesn't even giggle or anything it
stays fixed..
Also, on another subject how would i make it appear next to the top
right hand corner of a cell in a table?
Can someone help me figure out how to show a hidden layer *ONLY* if the
browser is IE for windows? I want it to remain hidden for everything else,
Netscape, Opera, Mozilla and anything for Mac. I'm not having much luck
out here.
