Below is JS code:
Code:
var request = new XMLHttpRequest();
request.open("GET", "http://127.0.0.1/get/file.json?filepath=c:\xxx.xxx");
request.onreadystatechange = function() {
if (request.readyState == 4) {
[Code]...
using above code, I wanna implement uploading/dowloading/parsing file with json format. however, the responseText always return null in FF. It it about to make me crazy.
And it was OK in IE at goDaddy linux grid hosting. WhenI changed to Reselleclub linux hosting it's not working.
script.js
function showMenu (str)
{
xmlHttp=GetXmlHttpObject();
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request");
[Code]...
I've been racking my brain for a couple hours now and doing a lot of searching and I cannot seem to find an answer. I want to know if it is possible to return the xmlhttp.responseText value from an AJAX function to the function that originally called the AJAX function.
Code:
//Set handler for server response.
xmlhttp.onreadystatechange = function()
{
[Code]....
I want to return the my_response variable to the original caller. No matter what I try I have been unsuccessful. I even tried assigning it to the global window variable using window.my_response = xmlhttp.responseText but it ends up being undefined.
Every example I've seen of using AJAX pretty much does something inside of the if (xmlhttp.status == 200) part to update the web page. I really do not want to do that.
Can I return the value?
I'm making an ajax call to return the contents for a page using the responseText property. I want to be able to define a javascript function in the page and call it, doing something like:
<script>
function test(){
alert('hi');
}
test();
</script>
However, none of the javascript in my page works. I'd imagine it has something to do with it being included as part of the responseText and the browser is not picking it up. I haven't been able to find any info about this online anywhere. Any thoughts?
Here's the function:
function getParentElementByTagName(child, TagName){
var cn;
if (child.parentElement){
cn = child.parentElement;
if (child.parentElement.tagName == TagName){
return cn;
}else{
getParentElementByTagName(child.parentElement, TagName);
}}}
although it finds the element, the function returns null ( on the line
'return cn', cn is not null though). Is my algorithm wrong ?
First of all, I'm sorry if I'm in the wrong group of discussion. I couldn't find discussion forum for vbscript. The problem I had is in vbscript coding.
The coding is as below:
Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adUseClient = 3
strDNSServer = WScript.Arguments(0)
strDomainName = WScript.Arguments(1)

if it's possible to return an array from my php generated content to ajax's responseText. I tried echoing back the whole array variable but can't seem to fully receive it in javascript.
somewhere in file1.php
<?php
$myArray = array();
$myArray['name'] = "ajax tech";
$myArray['age'] = 20;
[Code]....
I am trying to read data from server using AJAX XMLHttpRequest.responseText.In received data, there are lot of similar type of characters which has tge value of FFFFFD (65533). I think, all characters which has the value above 127 are converted to default character.

This seemed like it should be so simple. It works fine in Firefox, but not in IE. The goal is to disable the form's Submit button, until the question is answered. (The alert is for troubleshooting.)
Code:
Obviously, this HTML is in a form:
Code:
In Firefox 2, document.getElementById is returning an HTMLDivElement,
in IE 7, it is returning an Object.
For example:
<div id="errorTableDiv">
</div>
....
errorTableDiv = document.getElementById("errorTableDiv");
alert(errorTableDiv);
errorTableDiv.appendChild(someTableNode);
Firefox prints HTMLDivElement and lets me appendChild() later on
IE prints Object and gives an error on the appendChild()
I do not understand why this happens or what the most socially
acceptable way to fix it is.
I have an input box and I want it to function so that when the user presses the enter/return key, it runs a js function. I have the following code:
input.onkeydown = function () {
if (event.keyCode === 13) {
// do something
}
}
This works in Safari, Opera, Chrome, and even IE, but not in firefox.
When an item is selected on autocomplete it triggers a button....
It works fine on the other browsers but not on FF...
this is the code:
case KEY.RETURN:
if (selectCurrent()) {
__doPostBack($("input[id*=ImageButton15]").attr("id"), "OnClick")
}
break;
This has me completely stumped. I have a multiple select form element in my HTML document that needs to be manipulated by two different sets of context-sensitive controls. One set of controls is marked up as follows:
<div id="divControls1" name="divControls1" style="display:none">
<form id="fControls1" name="fControls1">
<input type="button" id="btnAdd" name="btnAdd" value="Add" onClick="addStuff();" />
<input type="button" id="btnEdit" name="btnEdit" value="Edit" onClick="editStuff();" disabled />
<input type="button" id="btnDelete" name="btnDelete" value="Delete" onClick="deleteStuff();" disabled />
</form>
</div>
When I load this page into Safari (on Mac OS X) and set the style of divControls1 to "display:block," I have an enabled "Add" button, a disabled "Edit" button, and a disabled "Delete" button, just as I expected. (I monitor selections in a multiple selection element to turn the buttons on and off.) But when I load this page into Firefox (also Mac OS X), all three buttons are disabled at startup. My page runs a function called startup() when the body fires onLoad. To try to troubleshoot the problem, I wrote this line at the beginning of the startup() function:
function startup() {
alert (document.getElementById("btnAdd").disabled);
...
When I run this code in Safari, the alert returns "false" (not disabled), just as I would expect, and intended. However, the same code in Firefox (Mac OS X) returns "true" (disabled) ... but the same code in Firefox (WinXP) returns "false"!
I really don't understand why I am getting this error (parsererror TypeError: data is null [object XMLHttpRequest]) after making the following AJAX request:
var base_url = $('span#base_url').text();
var model_url = "index.php/status/get_xml/"
$.ajax({
type: "POST",
[Code].....
So I am wondering why the .ajax function has an error, and yet the XML is being returned?
I'm using the $F of the prototype library to send data through the Ajax
Request. I'm having problems using the $F to reference fields sent
back through an original Request. My first request sends a form back
to the user in the type such as <input text name=foo> and at the bottom
of the returned form I have a second ajax call to send the fresh data
to the another script. The problem is that the new data in the form
cannot be referenced from $F. My question is how can I pass the new
data in the javascript to another Ajax call either by $F or by other
means?

I want to get the solution for a null xml response at the moment if there is no error i made a work around so the xml returns a fullstop which shows up as an error but in white. I would like to know if there is a way to keep the elementByiD as null when the xml is null as it was returning the error object required is there a better way of doing this????

View 2 Replies View RelatedI used to call web service with parameter like this and works fine.
function InvokeRequest(Url, Param, SuccessCallback, ErrorCallback) {
$.ajax({
type: "POST",
url: Url,

But instead of firing the success callback, it alert the result 200 ok with the JSON result.
I have researched this error/bug/mistake thoroughly with no success. I must be the only one experiencing it. Also, this takes place on every site I develop with jQuery ajax. It happens regardless of whether I use .get, .post, .ajax etc. Problem: The result returned to my ajax function always has a zero (0) appended to it.

Anyone know how to return true or false to an event handler based upon the results that come back from a Prototype Ajax.Request call?
I have a link with an onclick handler that calls a function getLoggedIn(), which looks like the following:
function getLoggedIn(type) {
ajax = new Ajax.Request(
'includes/checkloggedin.php',
{
method: 'get',
parameters:'&type='+type,
onComplete: checkLoginResult
});
}
As any analysis of request.responseText occurs in checkLoginResult(), not getLoggedIn(), how can I pass an Ajax-response-determined return value back to the event handler?
I'm new to ajax and coded a script that returns the result of a php file. It is fine if it is just text, but if it has html included it prints out the tags instead of treating it like html. How do you treat it as html? I've heard of innerHTML but was told it isn't viewed as standard compliant and some browsers don't even support it.

I thought that the value of startDate would end up as the defaultDate param for datepicker. No luck. Only an obscure little message in firebug console: "missing: before statement"
