View 3 RepliesI'm a newbie trying to modify the code in an AJAX tutorial to load data from an XML file, and it is not working. The code is in a php file that is invoked with the URL:getXMLTest.php?showName=photoShowTest.xml The code I've written (mostly copied from the tutorial, actually) is:
<!Doctype HTML>
<html>
<head>

I heard there is something called XMLHttpRequest that is compatible to all browsers. What does that actually do? Is there something to do with Javascript?
View 2 Replies View RelatedI have a very important question. I am currently attempting to create a Javascript file to test the HTML5 File API. First of all, I want to dynamically obtain a local file using Javascript and Google Chrome. I have succesfully done that by using a function which returns a XMLHttpRequest() object. However, when I try to access the content of it, I get empty space.

Can anyone tell me how to use XMLHTTPRequest or MS ActivcXObject open a
local file?
I've been using the form plugin to process some data in a form and was working perfectly until I added a new input (type="file") to upload images, for some reason now the plugin wont go past the beforeSubmit: section, the weird thing is that if I change the field type to text it works perfectly.Is it something I'm doing wrong? Or do I have to do something else with file type fields?
View 6 Replies View RelatedI have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page.
The script works fine when the requested XML file is stored on the same server as the script.
The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers?
Javascript Code
window.onload = initAll;
var xhr = false;
function initAll() {
document.getElementById("makeTextRequest").onclick = getNewFile;

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.
1. - I am new to this
2. - Using the following .js file:
Code:
function makeObject(){
var x;
if (window.ActiveXObject) {
x = new ActiveXObject("Microsoft.XMLHTTP");
}else if (window.XMLHttpRequest) {
x = new XMLHttpRequest();
}

But I dont know how to get only the inputs in the div.
I am trying to write a js that validates a form with two text inputs. The two inputs are: 'D_techA' and 'D_techB'. I just want to add up (sum) the two input fields (which must be positive numbers) and make sure that they add up to exactly 100 (not more and not less). If they do not add up to 100, then an alert should pop up that says "The two values must add up to exactly 100." I have tried and tried to write a js that does this validation (looking at numerous validation scripts posted in this forum and elsewhere) and I just cannot seem to make it work.

I have done lots of looking on the web, but am still unable to figure out why I can not make this simple assignment work.I just need some help with getting something to happen when the user hits submit. What I really want is for a new page to appear with the message using the user inputs, but I would be very happy with just getting the input to appear in the text area that I put in or even for the alert box to pop up with the input. I can work on validation code after I can get some kind of output to work.....
Here is the code I have written:
<html>
<head>
<title>Name and Age</title>
[code]....
The inputs for the fields of mth6, mth12, mth18, mth24, set50, set75, set 80 and set85.
I would like a way for it to round up to the nearest tenth.
IE:
from 2571 to 2580
from 148 to 150
ect.
any suggestions? Code:
Do you know how gmail's textarea stretches to accomodate text?
I want my inputs to behave like that.
I tried using css:
fit: fill;
But that didn't work. Not even in Mozilla.
How do I do this?
In other words
<input type="text" name="name_first">
<input type="text" name="name_middle">
<input type="text" name="name_last">
I want the fields to line up like this.
+---------+ +---+ +-------+
| Garrett | | S | | Smith |
+---------+ +---+ +-------+
and if the user changes "name_middle" to "Sean", then the middle field should expand.
+---------+ +------+ +-------+
| Garrett | | Sean | | Smith |
+---------+ +------+ +-------+
I think I'll need to know the width of the input's value. I think that's actually possible in IE's Range.
I have 100 inputs with name - table[].
How to get their value with jQuery,like $_POST['table'] ,as I do in PHP.

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?
