JavaScript - How To Resolve A Variable Not Defined Error In A Function
Hi,
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: Code: <SCRIPT language = "JavaScript">
var storedLetters = 'sideways';
function requestLetters(aString)
{
var validLetter ='';
var inputLetter = window.prompt('Please input a single lower-case letter', '');
while (storedLetters.indexOf(inputLetter) != -1)
{
inputLetter = window.prompt('You have already tried ' + inputLetter + ' . Please try another' + ' letter.');
}
validLetter = inputLetter;
return validLetter;
}
requestLetters(storedLetters);
document.write(validLetter);
</SCRIPT>
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. Can anyone see why this is the case? Thanks. Similar TutorialsHello I have a php page in which I declared a js variable... right at the top of the page... <script type="text/javascript"> var tester = 0; </script> Later in the page I test this variable... <script type="text/javascript"> if (tester==1){ do some stuff!! } </script> But I keep getting an error variable _tester undefined Am I missing something obvious... I am new to js... but this seems really straightforward i keep getting error Call to undefined function codeandurl() below is my code PHP Code: <?php $value= strip_tags(get_field('link',$post)); $resultid=get_field('resultid',$post); codeandurl($resultid,$value); ?> <div id="result"></div> <script type="text/javascript"> function codeandurl(resultid,url){ $( "#result" ).text(resultid); $( "#result" ).dialog({ modal: true, buttons: { Ok: function() { $( this ).dialog( "close" ); } } }); window.open(url); return false; } </script> I'm having some issues with firefox, chrome seems to work ok. Firebug is giving me an error stating country is not defined. The line it's saying it's on is where the function for an ajax call to populate a select input on page load. Here's the script that sets up the functions to call and fill the state and city values: Code: <script src="/components/com_helloworld/js/request.js">
/****************************************************

</script>
<script>
function handleOnChange(dd1)
{
var idx = dd1.selectedIndex;
var val = dd1[idx].text;
var par = document.forms["cbcheckedadminForm", "adminForm"];
var parelmts = par.elements;
var cb_statesel = parelmts["cb_state"];
var country = val;
var directory = ""+document.location;
directory = directory.substr(0, directory.lastIndexOf('/'));

And here's how it's being triggered on page load: Code: <script>
function addLoadEvent(func) {
var oldonload = window.onload;
if (typeof window.onload != 'function') {
window.onload = func;
} else {
window.onload = function() {
if (oldonload) {
oldonload();
}
func();
}
}
}
addLoadEvent(function() {
ajaxFunction(document.getElementById('country').value);
handleOnChange(country);
setupDependencies('cbcheckedadminForm', '');
handleOnChange2(cb_state);
});
</script>
I'm not sure why it says it's not defined as it clearly is. This error is causing the dependent drop down script to not work in firefox causing the child dropdowns to not hide. I did notice something odd though, if I remove the doctype line it works ok. I did this as firebug was throwing an error on another page claiming it had a syntax error so obviously something somewhere is messed up. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="<?php echo $this->language; ?>" lang="<?php echo $this->language; ?>" dir="<?php echo $this->direction; ?>"> When the doctype lines are removed firebug throws this error: window.document.forms[arguments[i]] is undefined [Break On This Error] for(var j = 0, e = window.document...ts[i]].elements; j < e.length; ++j) { in formmanager.js. Hi, 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 onloadXMLDocRefresh('File.php','txtHint') button is clicked? The button works to load the script, but the refreshing the div is not. My script is: Code: <script type="text/javascript">
function loadXMLDocRefresh(File,ID){
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
}
else {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(ID).innerHTML=xmlhttp.responseText;
timer = setTimeout('loadXMLDocRefresh(File,ID)',5000);
}
}
xmlhttp.open("POST",File,true);
xmlhttp.send();
}
</script>
Hi, I am facing a problem in passing replace() function as an argument in user defined java function, can any one help me how to resolve it? intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '\' to '\\' I am posting my javascript function he <a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\\/g,"\\\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a> function OpenDocPreview(url, docname) { alert('message from search base : ' + url + ' ' + docname); } thank you, Hi, I have written a function to compare each character in startString with another nominated character (nomChar). If they are the same this character is written to outputString, in the same position. If they are not the same a character is lifted from the same position in altString and placed in the same position in outputString instead. I hope that's clear! Code as follows: Code: function compareChar(startString, altString, nomChar)
{
var outputString = '';
outputString.length = startString.length;
var nextLetter = '';
for (var count = 0; count < startString.length; count = count + 1)
{
nextLetter = startString.charAt(count);
if (nextLetter == nomChar)
{
outputString.charAt(count) = nextLetter;
}
else
{
outputString.charAt(count) = altString.charAt(count);
}
}
}
document.write(compareChar('boston', 'denver' , 'o' ) );
However, the line of code within the if statement Code: outputString.charAt(count) = nextLetter; keeps generating an 'Invalid assigment left hand side' error message. Can anyone see why this is the case? Thanks. Hi all, I am relatively new to java; hence I know the basics, but have been thrown into trouble because I am currently working with a cms system that doesnt keep within the correct name conventions (pre defined). Within a form, I simply want to set a date to todays date: <script type="text/javascript"> function initdt(mf) { var t = new Date; mf.01-date.value = t.getDate(); mf.02-month.value = t.getMonth() + 1; mf.03-year.value = t.getFullYear(); } onload="initdt(document.WBForm);" </script> This works perfect on a form I create, but sadly I must use a form within a pre defined system that uses "01-date" Is there a way around this? A simple way of setting 01-date to t.getDate(); Your help will be very much appreciated Regards Damon Simpson Hi guys my site is not working fireug says that the function 'changevalu()' ia not defined but it is heres my site Code: <!doctype html>

JavaScript: Code: function test() {
alert('dsd');
}
HTML: Code: <a href="#" onClick="test()">Test Link</a> JS Error: Code: Error ``ReferenceError: test is not defined'' [x-] in file ``file:///C:/Users/Martyn%20Ball/Desktop/test.php#'', line 1, character 0. Okay wtf. Ok, I have an event handler for a click - ala: using prototype and here is a snippet. Code: spotL = some_length_of_an_array;
$R(1,spotL).each(function(n) {
$('spot_btn_' + n).style.display = 'block';
$('spot_btn_' + n).observe("click", function(){countdwn_clear();} );
});
Now, that code above fires off AFTER I call an init function that just runs thru some things... But not only that, that function "countdwn_clear()" loads before I call the code above... so its there. Now, the "element" I am trying to attach that event handler in an anchor tag in a UL element ala. Code: <ul id="buttons" style="display: none;">
<li id="spot_btn_1" class="selected"><a href="javascript://" id="btn1">1</a></li>
<li id="spot_btn_2"><a href="javascript://" id="btn2">2</a></li>
</ul>
so, I originally thought it that I was trying to attach an event handler to an element in another that had a display of none -- so I switched it to block and I'd still get this error: countdwn_clear is not defined NOW -- if put this right below the function call, ala: Code: function countdwn_clear(){d_some_code_here}
$$("#buttons li")[0].observe("click", function(){countdwn_clear();} );
$$("#buttons li")[1].observe("click", function(){countdwn_clear();} );
^^^^ that works! why?
In one case, i am calling it right below the function and I am using a different reference: $$("#buttons li")[1] in the code where I "build" it, I have: $('spot_btn_' + n).observe("click", function(){countdwn_clear();} ); ???? could it be the event is on the "li" instead of the "a" or ? I don't get it. Any ideas? Here is my function: Code: function mod_selection(val1,val2) {
if( -1 != navigator.userAgent.indexOf ("MSIE") ) {
var range = document.selection.createRange();
var stored_range = range.duplicate();
if(stored_range.length > 0) {
stored_range.moveToElementText(textArea);
stored_range.setEndPoint('EndToEnd', range);
textArea.selectionStart = stored_range.text.length - range.text.length;
textArea.selectionEnd = textArea.selectionStart + range.text.length;
}
alert('hi');
// Get the text area
var textArea = $("#text_edit");
textArea.hover(function() {alert('hi');})
// Do we even have a selection?
if (typeof(textArea.selectionStart) != "undefined") {
// Split the text in three pieces - the selection, and what comes before and after.
var begin = textArea.value.substr(0, textArea.selectionStart);
var selection = textArea.value.substr(textArea.selectionStart, textArea.selectionEnd - textArea.selectionStart);
var end = textArea.value.substr(textArea.selectionEnd);
// Insert the tags between the three pieces of text.
textArea.value = begin + val1 + selection + val2 + end;
}
}
}
Basically what it does is insert BBCode tags for whatever text you have highlighted. Here is my HTML for it: Code: <div class="two-row">
<label>Content: </label>
<a href="#" onclick="mod_selection('','');return false;">B</a>
<input type="button" value="I" onclick="mod_selection('','')" />
<input type="button" value="U" onclick="mod_selection('','')" /><br />
<textarea id="text_edit" name="body" rows="25" cols="51"><?php if(isset($_POST['submit']) || isset($_POST['preview'])) { echo $_POST['body']; }else { echo $news_body; } ?></textarea>
</div>
It says the mod_selection is not defined. I'm doing alert('hi'); for testing purposes and it won't print hi.. sooooo I feel like I need a second pair of eyes. I want it to at least recognize the function before I debug it any further. Hi Guys, I have a new problem My site is run on wordpress, but I'd like to customise the menu so that if the user is logged in the menu displays "Logged In" and if they are not it displays "Log In". Normally I would just use an if statement in PHP to output the required html, but as I can't use PHP code in the menu item I need to use Javascript. So, the way I figured this would work is: 1) PHP code in the header checks to see whether the user is logged in 2) This code then outputs JS to define a variable (varCheckLogin) 3) JS within the menu checks varCheckLogin and outputs the html i want This sounds good hopefully. Unfortunately this isn't working at the moment. The code I have is: HEADER: (I know this works as the variable is being output correctly in the source code) Code: <?php if (is_user_logged_in()) {
echo '<script type="text/javascript"> varLoginCheck = "Yes"; </script>';
} else {
echo '<script type="text/javascript"> varLoginCheck = "No"; </script>';
}
?>
MENU ITEM: Code: <script>
if (varLoginCheck = "No")
{
document.write('<span class="mmLogin">Log In</span>');
}
else
{
document.write('<span class="mmLogin">Logged In</span>');
}
</script>
I put an alert in the menu item and it always sees varLoginCheck as "Yes". Any ideas why this could be? All help is much appreciated. Thanks Sam Code: $(document).ready(function(){
var theText=["Text one","Text two","Text three", "Text four"]; // Build the array of text
var arrayRows = theText.length; //Get the length of the array (Note: This starts at 1 not 0 like the array)
var i=0; //Set a counter
document.getElementById('textHere').innerHTML =theText[i]; //Fill in the space with the first piece of text
time = setTimeout("next()", 2000);
function next() {
if (i == (arrayRows-1)) {
i = 0;
}else {
i++;
}
$("#textHere").fadeOut("slow", function(){
document.getElementById('textHere').innerHTML =theText[i];
$("#textHere").fadeIn("slow");
});
}
function prev() {
if (i <= 0) { // If its below 0 go to the max
i = arrayRows-1;
}else {
i--;
}
$("#textHere").fadeOut("slow", function(){ //Fade out the area
document.getElementById('textHere').innerHTML =theText[i]; //Change the text to the next piece of text
$("#textHere").fadeIn("slow"); // Fade in the area
});
}
$("#prevText").click(function(e) {
e.preventDefault(); // Stop the link being a link
prev();
});
$("#nextText").click(function(e) {
e.preventDefault();
next();
});
});
When i click the links the functions work, however the setTimeout doesnt, can anyone help me figure this out? In jquery-1.4.2.js I find the following - - - hide: function( speed, callback ) { ... } - - - Where is this syntax defined? ... and is it semantically different than - - - function hide( speed, callback ) { ... } - - - I've been working on a web-site and I've run into a problem. None of the buttons I've created will access the functions that they're supposed to access. When I used the JavaScript console in Chrome it threw the error Uncaught ReferenceError: (function) is not defined I've looked over it for syntax errors, but I couldn't find any. Am I missing anything? Here's my unfinished code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

This is an admittedly convoluted script, so I'm not surprised it's a bit buggy. Basically, I'm arranging several hundred small divs on a page. This code writes each of them onload , and checks urlArray to see if the specific div being written has a function attached to it, then enables onmouseover / onmouseout hand pointer/default pointers to it, and, of course, runs the function onclick . Code: var urlArray = ["main", "none", "none", "none", ... (snip) ]
var i = 0;
function writeDivs(){
document.write("<link href='css/css1.css' rel='stylesheet' type='text/css' />")
while (i<=447){
document.write("<div class='posDiv' id='div"+i+"' onclick='javascript:if(\""+urlArray[i]+"\" != \"none\"){window["+urlArray[i]+"()]}' onmouseover='javascript:if(\""+urlArray[i]+"\" != \"none\"){this.style.cursor=\"pointer\"}' onmouseout='if(\""+urlArray[i]+"\" != \"none\"){this.style.cursor=\"default\"}'>"+textArray[i]+"</div>");
i++;
}
}
The script as it appears here runs great in chrome, but Firefox tells me that "main" is undefined whenever I click or roll over the div, and IE says "object expected" when I click. "main" is the name of a function defined in an external js file (though pasting the function into the main document doesn't do anything). In fact, the whole of the above script may not even be relevant, since the following doesn't work either: Code: document.write("<div class='posDiv' id='div"+i+"' onclick='javascript:main()' >"+textArray[i]+"</div>");
I need a fresh set of eyes on this. Any volunteers? ~gyz I have a good understanding of javascript although I am new to working xml. So I am having a problem getting javascript to recognize that my parameter value in my function call is an attribute in my xml. I called the js function like this: Code: <a href="#" onClick="ebookCategory(marketing);">Marketing</a> Here is my js function: Code: var category;
function ebookCategory(category) {
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","ebook.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
document.write("<table border='1'>");
var x=xmlDoc.getElementsByTagName(category);
for (i=0;i<x.length;i++)
{
document.write("<tr><td>");
document.write(x[i].getElementsByTagName("bookCover")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("description")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("price")[0].childNodes[0].nodeValue);
document.write("</td><td>");
i++;
document.write(x[i].getElementsByTagName("bookCover")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("title")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("description")[0].childNodes[0].nodeValue);
document.write(x[i].getElementsByTagName("price")[0].childNodes[0].nodeValue);
document.write("</td></tr>");
}
document.write("</table>");
} // end ebookCategory()
Some of the aspects in this function are new to me, xml stuff. Here is my xml setup: Code: <ebook category="marketing"> <bookCover><img src="/millionaire/ebooks/covers/miracle2.jpg" height="150" width="150" /></bookCover> <title>Marketing Miracle</title> </ebook> I appreciate any help in the matter Greetings all. Please let me apologize in advance if this is a tremendously stupid question, but I'm new to Jquery and ASP... and I'm suddenly building an entire site made of both. *sigh* I keep getting an error message in Firebug in relation to the accordion menu I created.

The only code that I wrote for this page is the bit you see above and the hrefs for the side nav. Any help would be massively appreciated! Thank you in advance! Hi, I am trying to get this function to work, it looks great in theory but I keep getting the error message file is not defined. What have I done wrong? The code is: Code: <head>
<script type="text/javascript">
function loadXMLDoc(File,ID){
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
}
else {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("POST",FILE,true);
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(ID).innerHTML=xmlhttp.responseText;
}
}
xmlhttp.send();
}
</script>
</head>
<body>
<input type="button" value="Test" onclick="loadXMLDoc('getToday.php','txtHint');" >
<input type="button" value="Test2" onclick="loadXMLDoc('getYesterday.php','txtHintYest');" >
</body>
Hi, I have the following script which should work in theory, however I get the error message that file is not defined. I have tried playing around with using variables and I can not work out how to correct this. My code is: Code: <head>
<script type="text/javascript">
function loadXMLDoc(File,ID){
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
}
else {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(ID).innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("POST",FILE,true);
xmlhttp.send();
}
</script>
</head>
<body>
<input type="button" value="Test" onclick="loadXMLDoc($File='getToday.php','txtHint');" >
<input type="button" value="Test2" onclick="loadXMLDoc($File='getTomorrow.php','txtHintTom');" >
