I would like to pass a link through the same page using XMLHttpRequest or what ever is best without reloading the page eg; I have :
<a id="prev"><? echo $prev;?></a>
<a id="page"><? echo $page;?></a>
<a id="next"><? echo $next;?></a>
if someone click on the link id='next' then they go to the next page where at the moment in the URL it says: default.php?page=3
Maybe this has been tackled in another post but I couldn't find it through some searching so here goes...I'm using an Ajaxy method to update an administrative form and what I would like to do is update multiple text fields when the onchange fires from a dropdown list. Basically, I pull up a business name in the dropdown and fields for address, city, postal, phone, fax, etc... is updated.
The script that I've cobbled together is really good at updating one item via the XMLHttpRequest() responseText property and I could send a string of variables that I could break out into an array to loop into the innerHTML of each item but I was hoping there would be a more sophisticated way to do it.Is there a way to pass a responseArray instead of just a string of text?
I have a simple a tag in html that when clicked I want to link to a random address picked from an array of possible links.
So in the code here I have an array of the links and I'm picking a random number from the length of that array, I'm then using that number to pick a random link from the array.
Code:
<script type="text/javascript">
var links_arr = ["http://www.link1.com","http://www.link2.com","http://www.link3.com","http://www.link4.com"]
[Code]....
This all works fine and the window.alert show randomly picked links from the array.
The problem is passing the link to the href of the a tag - how can I use the link in the href ?
Code:
<a class="buy" href="javascript:link()" target="_blank">buy</a>
I have one page which is the server processing where the link is and the other page which shows the user page.On clicking on the link I manage to make a panel (slide toggle kind) be displayed alright. But I still need that on clicking on that link a value is passed. I think I have to write a couple of lines more in the Ajax snippet but dont know how exactly. I have seen a similar question but havent been able to translate it to my specific case.[code]Well, somewhere in the middle or maybe in another Ajax snippet I should put that $get and this should be returned so that a SQL query can take that value and work with it.

Code:
i had a text link to submit the form Ex:

i want to pass those values but errors occurs, this.form is not a property, but i need to pass that value because my validation requires so.

I am using a script so that a url selected from a dropdown is given control using the window.location method. This depends on the onsbumit definition attached to the action statement. All that works well. However, I have other checkboxes etc. on the form, and their values are no longer submitted when I used this onsubmit function. Is there a way I can get them to work... Here is the script and the form:
View 1 Replies View RelatedIs it possible? Say We have a list of suppliers link like
A supplier
B supplier
when right click on a supplier, a context menu(that has
"details","view products", etc) appears and click on "view products
for this supplier" this click will redirect users to products page
showing all products from the supplier.
So href should look some like this
<a href="RightClicked(ཆ')">A supplier</a>
<script>
function RightClicked(supplierID)
{
// don't know I am making this up here
if (viewDetailsClicked)
ShowDetails(supplierID);
else if (viewProducts)
ShowProducts(supplierID)
etc
..
}

Can it be done, does anyone have the script?
I need a counter that will display beside a link, with the number of times the same link has been clicked. I do not have FTP access to the site, since it is based on a CMS.
View 1 Replies View RelatedI have been trying to grasp the whole 'Pass By Value/Reference' thing for a few hours now. From what i can make out:
Passing by value will make a copy of the value, pass it as a function argument and the function will store the changes, the original value is not affected. So for example:
JavaScript Code:
var cost = 145;var postage = .3;var a = function() {return cost + postage;} //Using an Anonymous function for this
If you was then to pass the value of 'a' to a function argument it would copy and not change the original value.
If you pass by reference it will change the original value. When you pass a reference to a value through a series of different functions and the value is constantly being changed the change happens on the original value and can be seen outside the function.
The problem is i cannot think of how or why this would be used. I havn't got to develop many large applications so im trying to think of a few situations when passing by reference would be used.
Yesterday I started rewriting the xmlhttprequest functions to an oo equivalent, but as it turns out, I don't get it right:
Code:
function Request()
{
this.req=init();
this.req.onreadystatechange = this.processedRequest;
//addEventHandler/attachEvent alternative
//doesn't work either
function init()
{
try
{
if(window.XMLHttpRequest)
return new XMLHttpRequest();
else
return new ActiveXObject("Microsoft.XMLHTTP");
}
catch(e)
{
alert(e);
}
}
}
Request.prototype.send=function(url)
{
this.req.open("GET", url, true);
this.req.send(null);
}
Request.prototype.processedRequest=function()
{
if (this.req.readyState == 4)
{
if(this.req.status == 200)
{
response=this.responseXML;
res=response.getElementsByTagName('result')[0].firstChild.data;
func=response.getElementsByTagName('feedTo')[0].firstChild.data;
eval(func+'('+result+')');
}
else
{
alert(this.req.statusText);
}
}
}
expected usage:
Code:
var x=new Request();
x.send(url); //the processing function
//the eventtrigger should activate the callback function
//when the xml has been returned
It seems like the problem is that I don't get to my "this.req" in the processedRequest function. Can anyone see where the problem lies, it has been turning me crazy all weekend already.

Ive been playing around with xmlHTTPRequest and was wondering if i was
programming a part of my code wrong.
what i want to do is have the browser access another part of my site
using xmlhttprequest.
however, when i use xmlhttp.open("POST",
'http://xml.mysite.com/test.php')
it fails, but if i use xmlhttp.open("POST",
'http://www.mysite.com/test.php') it works. Is access to another url
restricted in xmlhttp?
I have something like this:
var xmlDoc=document.implementation.createDocument("", "", null);
but in opera xmlDoc.load(...) won't work, so I use:
XMLHttpRequest, and I have all needed code... let's say it works...
So I got serviceRequest.responseXML and is there a way to initialize xmlDoc
in my case ? I am asking because I have code that uses xmlDoc.load(...) in
FF and all code that's need to futher work with XML written. So this would
be comfortable for me to use xmlDoc instead of creating everything from
start.
I'm fetching some HTML files with XMLHttpRequest and dumping the
ResponseText into block elements; works fine except that single and double
quotes are being displayed as question marks (inside of a black diamond in
FireFox)
What's going on ? What is the workaround ? I've tried this:
divElement.innerHTML = x.responseText.replace(/?/g, "'")
but it does nothing ... even if it did work it would not be distinguishing "
from '
I would like to use the xmlhttprequest-object to send an http request
to my server. The http request is used to switch the light on through
home automation.
However it's not working, and I can't find the problem.
Could it be that the apache-server is located on 192.168.0.21 and that
the http request is sent to 192.168.0.21:8080?
function XML_request(func) {
var onreadystatechange= func;
this.method = "GET";
this.get = function(url) {
var request = null;
var state_change = function() {
if (request.readyState==4) {
if (request.status==200) {
onreadystatechange(request);
} else {
return null;
}
}
}
try {
request = new XMLHttpRequest();
} catch(e) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {
return null;
}
}
if (request===null) {
return null;
}
request.onreadystatechange = state_change;
request.open(this.method, url, true);
request.send(null);
}
}
var req = new XML_request(function(response) {
response = response.responseXML
alert(response.getElementsByTagName('blah')[0].firstChild.data);
});
req.get('index.php?mode=blah&a=response')
i didn't like the examples I found so this is suitable.. I only tested in ie and firefox though.. so let me know what I may be missing.. or criticism in general.
I'm working on an application that uses ajax and we are going to have a version that people with browsers that don't support the XmlHttpRequest object. My problem is what's the best way to check this.
I have tried the following
var xmlreq = new new XMLHttpRequest();
if (!xmlreq){
// handle the browser stuff
}
In netscape 4.7 this results in an error that I don't seem to be able to recover from and I don't think this is the best approach to this problem.
While accessing my web service i am getting XMLHttpRequest status=0 in Crome/Mozilla and in IE getting XMLHttpRequest status=406. What is the solution for it so that i will successfully get responseText from server? I have tried accessing my html code with localhost but its getting same error,while when i run my code in that localhost location through local drive then it's working. why this is happning i didn't get?
View 1 Replies View RelatedI got a javascript function to pull contents from a php page, let's call this page B to the actual page, let's call this page A.
As I know when a page gets loaded the javascript on that page won't execute, am I right?
Now I need the javascript code on that page B to get executed. Is that somehow possible?
I'm loading a javascript within a webpage on domain A from domain B like this:
Code:
<script type="text/javascript" language="JavaScript" src="http://domainB/path"></script>
Works perfectly, the script loads and executes. But calling XMLHttpRequest.open accessing Domain B from within this script doesn't work: Permission denied.
Now, I know of the cross domain security rule, but why can I load a script from Domain B, but not make a request with XMLHttpRequest to Domain B? Alle the counter scripts do exactly this... Any advice?
I'm using Firefox 1.5 and FCKEditor in a CMS app. Everything works in older versions of Firefox but in 1.5 I get a javascript error saying that the XML file holding the styles can't be loaded. Here is the code where the xml request is made:Code:
FCKXml.prototype.LoadUrl = function( urlToCall )
{
var oFCKXml = this ;
var oXmlHttp = FCKTools.CreateXmlObject( 'XmlHttp' ) ;
oXmlHttp.open( "GET", urlToCall, false ) ;
oXmlHttp.send( null ) ;
if ( oXmlHttp.status == 200 )
this.DOMDocument = oXmlHttp.responseXML ;
else if ( oXmlHttp.status == 0 && oXmlHttp.readyState == 4 )
this.DOMDocument = oXmlHttp.responseXML ;
else
alert( 'Error loading "' + urlToCall + '"' ) ;
}
Everything works in IE but Firefox just gives the error that is set in the final else. Any ideas on how to debug further or fix (preferrably fix).
The code I am writing fetches a csv file with weather data and updates the contents of the page every 5 seconds. It works correctly as far as I can tell in Firefox, IE, and Chrome. In Safari it works correctly the first time it loads but gives the following error any time after that.
Error: NETWORK_ERR: XMLHttpRequest Exception 101 I've searched for this but couldn't find anything that seemed to be similar to the issue I'm having. The error occurs on the xmlhttp.send(null); line.

I have a web app, written in Javascript, that communicates to a back-end
server via XMLHttpRequest.
The logic goes:
* Login
* Perform transaction
* (delay while the user does something)
* Perform transaction
* ...
* Logout
It would be really convenient if I could make the whole thing a single HTTP
connection. That way, I avoid needing IPC and session management at the
server end, and a single instance of a CGI script can represent the entire
session. When the socket gets closed, the CGI script terminates and
implicitly logs the user off. All very simple.
Can I use HTTP pipelining with XMLHttpRequest to do this? The docs seem to
say (it's quite hard to tell) that I have to call open() after each send(),
which will presumably create a new HTTP session. Can I 'persuade' the
browser to reuse an existing session?

include HTML, the code appears as is, instead of the formated HTML. Please
