Ajax :: Returning A Value Directly From A Function?

Dec 1, 2009

I'm attempting to simplify my javascript code when it comes to ajax, but afterwords it only prints 'undefined' to the screen rather than what I want it to print.

I want to be able to put something like this on my main page onclick="document.getElementById('output').innerHTML = print_output();" where print_output() is the ajax function. This way I don't have to use a function to assign values directly to innerHTML and I don't have to muck about with a js file whenever I want to change my page layout.

To do this, I created a recursive function:

function print_output(return_value) {

if a value has been passed to the function, simply return it
if(return_value || return_value == 0) {
return return_value;
}

[Code].....

but like I said, it prints 'undefined' out to the screen. Why isn't this printing the contents that it receives from 'index.php' like it's supposed to?

AJAX :: User To Be Able To Edit The Data Set And Have Those Changes Written Directly Back To The MySQL Database?

Jul 11, 2010

I have a form.On the form I have a drop down box that allows the user to select a data set to work with (A or B). The table loads just fine and all is right with the world. No problems there.What I need is for the user to be able to edit the data set and have those changes written directly back to the mySQL database. They also need the option of deleting a record entirely.I know how to do all the database queries, updates, etc. I just don't know how to write the ajax forms to accomplish this.

JQuery :: $.ajax Not Returning Data ?

Jun 10, 2009

Currently, I'm building a website with jQuery. The function below helps me to get content from a database. In the file content_ajax.php there are some functions to handle ajax-requests. JS calls the PHP-function correctly (I've send an email to myself inside that function to check) but the script doesn't return 'succes' and doesn't give me an error...Also, when I put an alert inside the succes and error function, it doesn't popup!

What may be relevant: - site uses mod_rewrite for friendly url's

I've included the relevant html and the javascript function below. There is some php code included which works but is not relevant to this question. The first ajax part of the function works. I have tested it with positive results in another context.

The part starting with "var x . . ." is the part that is not working. This part is supposed to generate the following html: Code:

AJAX :: Cross-domain Returning Status Code?

May 27, 2010

I'm making a script that requires cross-domain scripting to get the statuscode of other files. I'm currently using a small PHP script to relay the files from the remote server onto mine. If I want to get the files directly using AJAX, it is not allowed for obvious reasons. I don't want the actual files, I only want to get the status code of that file, and it is going to be either a 404 or a 301. I would've assumed that as the AJAX call is never attempted, the statusCode will be 0, and this is what the actual call variable returns.

However, in Firebug it shows the statuscode next to the request (404 or 301), even if, the call has never been made. Why is the statuscode appearing in Firebug but not in the statuscode variable?

Why Is Function Returning False?

Aug 13, 2011

So for whatever reason the convertToArray function in the following code returns false if the argument is more than 1 character long. If it's 1 character long it just returns the character as an array with only one value.What I'm trying to do is take a string of numbers, plus signs, and minus signs and convert it to an array.

Returning Variable From Within Nested Function

Mar 9, 2009

The code is below but basically I have two global variables, then I have a function and then a function within that, I am simply trying to update these global variables from within the nested function so i can then go on and use them in another function! this sounds like quite a straight forward request to me, but maybe it can not be done? When I do an alert on the variables (after I have apparently updated their values) I get 'undefined'!

Code JavaScript:
var resultLatB;
var resultLngB;
function getLatLngFromTown(town, callbackFunction) {
var localSearchB = new GlocalSearch();
localSearchB.setSearchCompleteCallback(null,
function() {
if (localSearchB.results[0]){
resultLatB = localSearchB.results[0].lat;
resultLngB = localSearchB.results[0].lng;
pointA = resultLatB;
pointB = resultLngB;

//THIS WORKS
alert("Test 1 = " + resultLatB);
alert("Test 1 = " + resultLngB);
}});
localSearchB.execute(town + ", UK");
//DOESN'T WORK... SHOULD IT?
alert("Test 2 = " + resultLatB);
alert("Test 2 = " + resultLngB);
}
getLatLngFromTown("oxfordshire",null);

//I WANT THIS TO WORK!
alert("Test 3 = " + resultLatB);
alert("Test 3 = " + resultLngB);

GetElement Function Returning Undefined Value

Sep 26, 2009

Here is a clip of code from a script project im working on. Now my document.getElementsByTagName is returning a "undefined" value.

<a href="[URL]" style="text-decoration: none; color: #EDDBAF; font-size: 16px;">
<center style="margin-left: 10px; margin-right: 10px;">
<font style="color: #EDDBAF; font-size: 16px;" id="title"></font>
</center></a>
<li id="name"><a http="[URL]" style="color: blue;">John Doe</a></li>
<script type="text/javascript">
var pname = document.getElementById('name').getElementsByTagName('a');

Now if I remove the ".getElementsByTagName('a')" it will actually work, but it also includes the <a> tag thats within the <li> tag, which I don't want.
document.getElementById('title').innerHTML=pname.innerHTML;
</script>

Returning ResponseXML, Set Within An Anonymous Function, Only Once ReadyState = 4

Dec 4, 2006

I have several functions with code along the lines of:

var xmlDoc = requestXML("ajax.asp?SP=SelectRelatedTags&tag=" +
array[i]);

The requestXML() function includes the code:

var xmlDoc = null;
http_request.onreadystatechange = function() {
if (http_request.readyState == 4) {
if (http_request.status == 200) {
xmlDoc = http_request.responseXML;
} else {
alert('There was a problem with the request.' +
http_request.status);
}}};
http_request.open('GET', url, true);
http_request.send(null);
return xmlDoc;

However, the last line (the return) executes before the readyState
reaches 4. How do I return the xmlDoc to the functions only once the
xmlDoc has been assigned? I tried putting the return statement in a
while loop with the condition that the readyState must = 4 - this
worked, but makes the browser popup a message saying the script is
slowing down the system.

JQuery :: Width Function Returning Zero On Occasion?

May 26, 2010

I have a weird bug that's occuring in pretty much all the browsers. If I close the tab, and then hit Ctrl -> Shift -> T to bring it back the width() method returns 0 on an appended image instead of what the image actually is. Hitting refresh on the tab removes this bug and everything works fine. I will also say that trying
.css('width') and
document.getElementById('divShadowLeft');
Both also return 0 for this bug.

I can't show all the code for security reasons, but I'll just outright ask.. what are the reasons that width() would return 0 on an image? I've checked to make sure that it was visible (both display and visibility properties), and I checked the length of the property to ensure it was there. I just can't figure out why width() is returning 0.

Here's a code snippet:
$(this).append('<img src="'+defaults["imagePath"]+defaults["imageLeft"]+'" alt="" id="'+defaults["imageClass"]+'Left" class="'+defaults["imageClass"]+'" style="" />');
alert('Length: '+$('#divShadowLeft').length+' | Width: '+$('#divShadowLeft').width()+' | Visible: '+$('#divShadowLeft').css('visibility'));
