Simple Case AJAX Alternative
Apr 25, 2006
If I want to send something simple to the server and I don't need a response, instead of using AJAX, I use this:
<html>
<head>
<script type="text/javascript">
function sendToServer(someText) {
var fakeImg = new Image();
fakeImg.src = "http://localhost/takeparam.asp?param=" + escape(someText);
}
</script>
</head>
<body>
<input type="button" value="press me" onclick="sendToServer('baloney');" />
</body>
</html>
Is there anything inherently "wrong" with this? I know that it requires javascript enabled. As far as I can tell it will work on more platforms that AJAX so that should be a good thing, right?

I am working on a search function to call some data from an XML document. It works fine except for the fact that it's case sensitive.
What method do I need to use from the String object to make it case insensitive, so that a J is the same as j?
I was thinking of changing my text box string to all lower case using toLowerCase(). If I did this, then would I have to do the same thing in the info retrieved from the XML document? I want to make it so that Tom is the same as tom - I'm just wondering where I would have to apply these - to both the XML doc (being read for the output) as well as the text box string (the input).
Just wondering if I'm overthinking this, or on the right track with toLowerCase().
Also, in my search, to filter the results from only entering a few letters (not the entire element, I'm using the substr() method. It seems to work but I don't know if this affecting the case somehow...

I know cross domain Ajax request are denied due to the security issues. As an alternative to this, I have heard of using JSON. I tried to use that, but I am unable to get it work. I had also tried the jQuery's $.getJSON() that didnot work as well.
Could you please provide me some working examples for this case?

I'm having some trouble trying to get a simple GET to work.
I have a page called 1.php with the following code:
This all works fine when I link directly to the page (I.e [url]), however when I load this page through jquery (so the url becomes [url]) the GET functionality stops working.

I'm actually new on jquery ajax. I just wanna ask a little idea about how to create simple file upload (with form) using ajax. I tried using this code:
//form html
<p id="status"></p>
<form id="form1" enctype="multipart/formdata">
<input type="file" id="photo" name="photo" />
<input type="submit" id="save" name="save" value="Upload" />
</form>
//php file
if($_POST){
$name = $_POST['photo']['name'];
$tmp = $_POST['photo']['tmp_name'];
$path = "images/".basename(name);
if(move_uploaded_file($tmp,$path)){
print("Done! File saved...");
}else{
die("Error on uploading!")
}}
//js
$(document).ready(function(){
var photo = $("#photo").val();
$.post("upload.php",{photo:photo},function(data){
$("#status").html(data);
});});

I'm pretty new to jQuery so try and go easy. Trying to do a simple AJAX POST using the jQuery post method and it doesn't seem to be working.
Heres my code:
$.post("sub-account-ajax.php", { email_address: "test@test.com" },
function(data){
alert("Data Loaded: " + data);
});
Heres the code for sub-account-ajax.php:
<?php
if (isset($_POST['email_address'])){
echo 'youre set';
}else{
echo 'nothing set';
}?>
When this code is executed I do not get any alerts or any error messages whatsoever. I've been pretty good with figuring things out so far with jQuery, but this is the first I'm stumped with.

I'm trying to create a simple registration form with ajax validation. I've got the form working almost how I'd like... a message appears on the page with the errors for each field entered incorrectly.
The problem is all the error messages appear in one div together and I would like to have each field have its own div containing only its own error.
I think I need to wrap my error messages in xml and use something like this -
Code:
- but can't seem to get it working
Does anyone know how I should modify my code to do this?
Attached are the 3 I'm currently using
And Here is my code for my ajax page only.

In Bourne shell, you can do:
case ($x) in
foo*)
;;
*bar)
;;
esac
so that the first case matches any string starting with "foo", the
second any string ending in "bar", etc. In Tcl, you can:
switch -glob $x {
"foo*" {
}
"*bar" {
}
}
and accomplish the same thing. I'm struggling to do that in
JavaScript. switch seems to follow C semantics and do a full-length
match. And String.match() doesn't seem to do glob-style matching so I
can't do:
if ($x.match("foo*")) {
...
Is there a way to match on patterns in a JavaScript control structure?

So I have some code like:
if (document.Insurance.State.selectedIndex == 1)
{
ifIll();
}
else if (document.Insurance.State.selectedIndex == 2)
{
elseKan();
}
else if (document.Insurance.State.selectedIndex == 3)
{
elseInd();
}
I am trying to replace the if-else statements with case statement as
follows:
var index = document.Insurance.State.selectedIndex;
switch (index)
{
case 1:
ifIll()
break
case 2:
elseKan()
break
case 3: elseInd()
break
}
This code doesn't work ! Am I missing something here?

I'm working on developing an RSS/RDF/Atom Parser in JavaScript. I've already successfully implemented complete support for RSS 0.9x and 2.0. So far, so good. However, I've run into two minor problems. One is mentioned here, and one is in another post.
The issue that I'm coming across is the case-sensitivity of getElementsByTagName() when parsing standard RSS (XML) tags.
Danny Goodman's JavaScript Bible says that the tag name string that gets passed as the parameter in getElementsByTagName() is case-insensitive. However, this is speaking in terms of HTML and the HTML DOM. I'm working with XML, and getElementsByTagName is handling the XML tags as being case-sensitive.
Can someone suggest a way around this? Can a regular expression be used as the parameter? If so, what would the syntax be (as I'm not very familiar with regex)? For example, I want a <textinput> tag to be handled the same as <textInput> (which is the correct syntax).

I am writing some javascript code and just wanted to check if a case statement could have OR / AND. If yes, what would the syntax be like.
What I need is this:
switch (country) {
case "US" || "Canada":
//do something
break;
case "Australia" || "UK":
//do something
break;
}
I can alternatively use IF statement but was curious.

Is this sort of thing possible:
var X = 'Moe'
switch (X) {
case 'Curly'||'Moe'||'Larry':
alert('Found one of the Three Stooges');
case 'Chico'||'Harpo'||'Zeppo'||'Grouco'||'Gummo':
alert('Found one of the Marx Brothers');
default:
alert('No matches');
This gives 'No matches' unless I only put a single string in the 'case'
lines. I've just been using VB's Select Case which is a similar flow
control but which allows conditional arguments in the 'cases'. I just
wondered...
I realise you could put each set of names in an array and iterate
through each array, but that's a different issue.

I'm experimenting with creating SVG dynamically and am finding that document.createElement is changing the case of the tags I input. This is breaking because, apparently SVG tags are case sensitive. For example, when I try to create a linear gradient element like so:var grad = document.createElement('linearGradient');what appears in the view source is:<lineargradient ...> (Note the lowercase "g")The tag doesn't work if the "G" is lowercase. Is there any way to specify in the <html> tag (or somewhere else) that the document should preserve tag case?

So, I have a list of items that need to have a new preset list item appear based on what day it is. I have the date script working (to test, change the first case to some random date and change the third case to todays date - 10192010 - It will fire that document.write). What I need the cases to do though, is set the visibility of certain list items.
This is just an example, there will be around 20 list items in the final project. As you can see in the first two cases, I've tried a couple different routes to no avail.
The Code (class references are irrelevant to this example, they belong to the final project):
<html>
<head>
<script type="text/javascript" language="JavaScript">

this is what im trying to do:
Code:
var field01 = document.getElementById("Field01").value;
field01[0] = field01[0].toUpperCase();
it doesnt work, the first letter of the field stays lower case BUT when I do this:
Code:
alert (field01[0].toUpperCase());
then it converts the first character to uppercase, well only in the alert box, the actual one still unchanged.
so i figure thats because it needs to be triggered somehow, it wont work by assigning it. i cant use it as return. are there any trigger methods that would just let me capitalize the first letter without any pop ups or anything?
