JavaScript - Return Variable Error
Hi,
I am looking for some help with function below, the $date variable will for months 01-09 return a value of 1-9 leaving out the 0 numerator Code: function reformatDate($Date)
{
var $date = $Date;
months = ["01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12"];
var parts = $date.split("/");
var m = parts[0];
for ( var i = 0; i < months.length; i++ ) {
if (months[i] == m ) {
var month = i;
}
}
$date = parts[2] + "-" + (month+1) + "-" + parts[1]; // +1 needs to be appended to month as JavaScript month starts at 0
_log("Date " + $date); //test date is in correct format
return $date;
}
so in above example if i pass a date 01/02/2015 it will return 2015-1-02 whereas i want it to return 2015-01-02 for the purposes of the function i need the $date to return 01,02,03 etc also can anyone explain why the zero is dropped before each number?

}
Similar TutorialsI need to get this script to work, I only included what im having the problem with. I am Using jQuery Library. Here is how this should work: .btnRoof div is clicked the parent id is retrieved as var pid a function called roof is called which simply changes a css background to "color" the function perform is called to get the "color1[0]" from the array. My Problem: perform() returns the word color1, color10, color1[0], or c. instead of images/cp-roof-blue.png as listed in the array. Code: $(document).ready(function() {
var color1=new Array();
color1[0]="images/cp-roof-blue.png";
color1[1]="images/cp-panel-blue.png";
color1[2]="images/cp-trim-blue.png";
function perform(name, x) {
alert(name[x]);
//alert([name][x]);
//alert(name+'['+x+']');
//alert(color1[0]); // correct
return name[x];
}
function Roof(color) {
$("#colorPicker .roof").css("background", "url("+color+")");
}
$('.btnRoof').click(function() {
var pid = $(this).parent().parent().attr("id");
Roof(perform(pid, 0));
});
});
I tried to clarify as much as possible, please let me know if I need explain further. Thanks. Hello 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 don't understand the logic of Break, Return False, Return True. It was never really covered in our college class, and I see everyone using it. I got an A in the class, if that 'proves' that I really tried to apply myself. NOTE: I understand what the function is doing. I just don't understand WHEN to use break, return false or return true if the the translator can determine the conditional statements. PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } else return false; } if the the translator can determine the conditional statements, why not write it like this: PHP Code: function submitForm(){ var ageSelected = false; for (var i=0; i<5; ++1){ if (document.forms[0].ageGroup[i].checked == true) { ageSelected = true; break; // what's the point for the 'break'? Won't the rest of the code be ignored since it passed the first condition? } } if (ageSelected == false){ window.alert("You must select your age group"); return false; } // why not leave the last else out? is it just a 'safety' catch, in case something other than true or false is inputted? else return false; // what's the point? } Questions: Why use return true, if the translator knows it's ture? Why use "return false" if the translator knows it's false and the alert window has already gone up? why not use "break" to stop the code? Why use the "return false" at the end "else" statement? Hi room, Hey, I opened up the source code for this page in google chrome and since i'm learning javascript, i wanted see if i could "read" it and figure out what was going on. I'm am having the hardest time understanding "return false" and "return true". Could someone step me through this via interpreting this code (in bold typeface): Code: var DefaultValue = 'Search';
function clearSearch() {
if (document.searchForm.q.value == DefaultValue) {
document.searchForm.q.value = '';
}
}
function validateSearchHeader() {
if ( document.searchForm.q.value == '' || document.searchForm.q.value.toLocaleLowerCase() == DefaultValue.toLocaleLowerCase() ) {
alert('Please enter at least one keyword in the Search box.');
document.searchForm.q.focus();
return false;
}
return true;
}
Thanks! Hi, I'm trying to use a form which is existent on one of my sites and try re-creating a similar form on another site for the exact same purpose. Here is the URL for the form on our website Cast Iron Cookware Depot. I have everything duplicated but running into form validation errors. Right now without event entering any data into the form and also the verification code the form still gets submitted but ofcourse runs into "object expected" error at onsubmit="return validate(this);"> by IE Debugger. Below is the total code and would appreciate if any of you gurus point out where the mistake is and also why the exact same code is working on one site is not working on this site. Thanks much in advance. Please help me! ------------------------------------------------------------------------ Code:

Regards Learner I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE). The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden. However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case. Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed? 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">
/****************************************************
* Ajax call to fill city values
****************************************************/
</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('/'));
Http.get({
url: "./components/com_helloworld/js/regvalues/states/" + country + ".php",
callback: fillcb_state,
cache: Http.Cache.Get
}, [cb_statesel]);
}
function fillcb_state(xmlreply, cb_stateelmt)
{
if (xmlreply.status == Http.Status.OK)
{
var cb_stateresponse = xmlreply.responseText;
var cb_statear = cb_stateresponse.split("|");
cb_stateelmt.length = 1;
cb_stateelmt.length = cb_statear.length;
for (o=1; o < cb_statear.length; o++)
{
cb_stateelmt[o].text = cb_statear[o];
}
}
else
{
alert("Cannot handle the Ajax call.");
}
}
function handleOnChange2(dd1)
{
var idx = dd1.selectedIndex;
var val = dd1[idx].text;
var par = document.forms["cbcheckedadminForm", "adminForm"];

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. Whenever I try to compile a script I wrote, I get the error, "class, interface, or enum expected" and it points to a spot in my script that I don't think should create an error... I've tried changing different things in the line it points to, but it doesn't help. Here's are some of the errors: Code: Code: var it = 0;
var udt = new array(10);
for(it = 0, it < udt.length, it++){
switch(it){
case 0: udt[it] = prompt("Type a name", "");
case 1: udt[it] = prompt("Type a verb", "");
case 2: udt[it] = prompt("Type an adverb", "");
//case 3: udt[it] = prompt("Type a
//case 4: udt[it] = prompt("Type a
//case 5: udt[it] = prompt("Type a
//case 6: udt[it] = prompt("Type a
//case 7: udt[it] = prompt("Type a
//case 8: udt[it] = prompt("Type a
//case 9: udt[it] = prompt("Type a
//case 10: udt[it] = prompt("Type a
}
}
document.write(udt[0] + udt[1] + "away as" + udt[2]);
Errors: Code: story.java:1: class, interface, or enum expected

I've looked over the first one and I have no idea why that is an error. If the reason is obvious to you, please be polite. I've only been using javascript for about 2 days. 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. Hi ,, im trying to access cells in the excel , but when iam using variabel inActiveSheet.Cells(1,k) im getting error "Expected :".

I have a javascript that takes information from a form and recompiles that information into a readable shift report. The problem I am having is with returns in the textareas. I tried: Code: theReport = theReport.replace("
","<br>"
but that space puts the rest of the var on a different line and screws with the results. How can I replace a return with <br>? I want the output to be this way Student: Doe, John eMail: jd@email.com Course ID: COIN-O70A.01 ----------------------- Can any one pls help me with the display. If I use alert instead of return then I works. But I need to display it in the document. Code: <html>
<head>
<title>Variable - Examples 1</title>
<script type="text/javascript">
function Student(firstName, lastName, email,courseID){
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.courseID = courseID;
}
Student.prototype = {
constructor : Student,
toString : studentInfo
};
function studentInfo(){
return this.firstName + "," + this.lastName + '\n'+ this.email + '\n' + this.courseID;
}
var student = new Student("Doe", "John", "Doeohn@gmail.com","COIN 70A.01");
</script>
</head>
<body>
<script type="text/javascript">
document.writeln(student.toString());
</script>
</body>
</html>
