3 Deep Function Call Not Returning To First / Resolve This?
Apr 23, 2010
I have a setup where I have a function, calling a function, calling a function. All functions do what they're supposed to do, but they don't return to the first function when all is done, so it doesn't display an alert that it's supposed to.
For those that don't want to look through tons of code and think they might know what I'm doing wrong, here's the "coles notes" version. code...

Using a while loop in a function, I am trying to test an input character against a stored string of characters. I want the function to return the input character only if it is not in the stored string of characters. The code I've prepared is as follows:
<SCRIPT language = "JavaScript">
var storedLetters = 'sideways';
function requestLetters(aString)
{
var validLetter ='';
[Code]...
The code works fine if I remove it from the function wrapper but if the function is called I keep getting an error message that the variable validLetter is not defined. :confused: Can anyone see why this is the case?

I have a button that when you click it displays the results of my db in a div. What I am trying to do is to get the results to update every five seconds.
I thought setTimeout was the best way to achieve this. However I am getting the error message that ID is not defined on the setTimeout line. I thought it would automatically input ID into the fields marked ID when the onloadXMLDocRefres ('File.php','txtHint') button is clicked?
The button works to load the script, but the refreshing the div is not.code...

<button onClick="return popup('<span onClick='selectShape(1, 1, 1)'>test<span>');" tabindex=Ɖ' onFocus="setFocusColor(0,3)">....</button>
This will work perfectly, but as soon as I need to pass Strings inside the selectShape function, I get stuck.
So the question is, how can I create the following and have it working
......selectShape(2, 'Tricky', ཤx5°').....

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.

I have a little problem in one of my functions, I would like to pass in a form field name and set the value to something that is passed in. here is my code:
function pickitem(id,type){
opener.document.getElementById("form").type.value = id;
window.close()
}
so i'm passing in an id and a formfield e.g. txtName The problem is with the type.value - i haven't touched javascript for ages so i'm really rusty!!

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?

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);

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>

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.

I know this is a simple question with a simple answer, but I can't seem to wrap my brain around it.Sorry for the infantile nature of this post. Anyhow, I am making an AJAX call via JQuery and need the function to return a value from a calling function, like so:

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'));

I have a function where in I call another function that assigns a value to a var. code...
For some reason my code below is returning 'undefined'. But when I place an alert(); before the 'return' it shows the correct value. However when I place an alert(); to show the var that is set to what the function returns it says 'undefined'.
Firebug throws no errors. I am using a little bit of jQuery.

I have this code:
HTML Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html>
[code]....
The practical scenario is I have several functions attached to the jQuery ajaxSucess event. Each function needs to execute once during initial load and after when the JQuery ajaxSuccess event is fired. So I am just looking to see if I can eliminate a a few lines of code and learn something new in the process, that is really all.

I have a very simple PHP script that returns JSON like this:
{"question":"What day is it?"}
And I'm trying to call it from another page using Ajax. My code looks like this:
var url = "/test.php";
$.get(url,
function(data){
$.each(data, function(i, value) {
alert(value);
}, "json"
);
});
When I run it I get each character printed out one at a time in a separate alert. And then when I used this line of code:
alert(typeof data);
It tells me that 'data' is a string. Shouldn't it be a JSON object?
