I've come across functions like the one below in many scripts.I just don't understand the purpose of the parameter! Nothing is being passed into the function when it's being called- so what's the point of specifying an argument???
function doSomething(e) {
if (!e) var e = window.event;
alert(e.type);[code].....
I'm using the Google AJAX APIs, but some reason google.load works when run through normal javascript, but if I call the method from my jquery ready function it doesn't work. Code and output is below
page.html
<script type="text/javascript">
loadGoogleStuff();
function loaded() {
console.debug("in loaded function");
}
[Code]...
window.loadFirebugConsole is not a function If I comment out line 3 in code.js, the console debug runs okay, so the ready function is running okay. Even though there's a reference to Firebug, the same error occurs in Safari too. Nothing on the page loads.

View 2 Replies View RelatedI'm trying to reuse a script I have but, I'm not able to due to the fact I can't use some variables in a function.
I would like to know why I am not able to use passed variables in javascript.
For example: I call a function submit_data( 'newDomainForm', 'add_domain', 'list_div' ), in the function itself I would like to use the form name (first variable passed) as document.form.domain_name.value.
Later on I would like to use the div id: list_div in document.getElementById( div_id ).innerHTML. This doesn't work.
I have to put the name of the actual div like this: document.getElementById( 'result' ).innerHTML
And to get the value of a form element I have to put the actual name like this:
HTML Code:
The code below is the relevant part to an autosuggest feature. The variable that isn't being passed is "firstValidIndex". It is being set appropriately, but when it is used in "sortArray()", its value is 0.
// here we must check to see if where the string matched was at the beginning of a string inside this.aNames
// firstValidIndex is the first index where the char is at the beginning of a string

I'm trying to make a time script for an app I'm making (this is not an HTML document; it's a .js file to be used with Titanium) however I'm having trouble getting the function to display and update.
function updateClock()
{
setInterval ( 'kiTime()', 1000 );
}
function kiTime ()
{
//Get current date and time
[Code]...
If I use kiTime() under the text field I will get the current time (or at least the time the app was opened), however if I call updateClock() it's blank.
This is the first question I couldn't find answered by Google! No doubt the answer is out there, but...
So I have a function that is being passed an array of nodes: some of them plain vanilla DOM nodes, (say, those created by document.createElement), others are jQuery nodes (say $("<div></div>").
What's the best way to determine if a node is of each type? I can obviously look at the node contents, but I wondered if there was a "best practices" here?

New to JS. Have ordered some new books, but need to get somethings going in the mean time. What I wanted to do is to link to a new page having a date range input in the form of 6 text boxes, 2 sets of mm-dd-yy, from and to, where the upon loading the page box 1 of the from would auto focus and then auto tab and then post where php could take over on the server side. Setting up the form and the lay out, no problem. Auto focusing went just like expected using the following code, included because on the next step everything fell apart.
Code:
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
So then the wheels came off and in response, began to simplify what was trying to be done to find where the issues were. As far as I can get working is:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc() {
alert("is this working");
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc()" maxlength="2" value="type a No." />
</body>
</html>
First issue with this: When I first get to the page everything is just as ordered. The focus is on the text box and the default value is "type a No." When I press a key onkeyup, I bring up the alert box with "is this working" in it. But when I refresh the page with the refresh button, after clicking the "ok" on the alert box, the character that was typed in is still displayed. If I use the link to the page, or the URL from the address bar, then the page reloads properly with the default value, "type a No".
How do you get the default textbox value using the refresh button as apposed to reloading the page using a link or from the address bar? Using Firefox 8.0 more important at the moment: If I change the script to pass an argument to the function the script crashes. It does not pull up an alert box and freezes. My guess is that I'm doing something wrong on a concept level. Changed the default value of the text box to " ". Looked like to me there was an issue with the size specification and the default string length as you could only enter in a key stroke by highlighting the text and replacing it.
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "[URL]">
<html>
<head>
<script type="text/javascript" >
window.onload=function() {
document.getElementById("input1").focus();
}
</script>
<script type="text/javascript" >
function myFunc(awe) {
alert(awe);
}
</script>
</head>
<body>
<input id="input1" name="input1" type="text" onkeyup="myFunc("123")" maxlength="2" value="" />
</body>
</html>
I want to call a javascript function when a <span> is clicked, pass two variables to it, and then use jquery to hide that span.
A simple example is:
The variables (1,3) & (8,9) are loaded dynamically with a php script. Adding the two variables together isn't the intent of the script, but it seems the simplest way to explain what i'm after.
So how do you get $(this) to work in a function that has to have variables passed to it?

why this parameter is not passed to function ?
var myDIVnode1 = document.createElement("DIV");
// etc
myDIVnode1.appendChild(document.createTextNode("a"));
// this shows "a"
alert(myDIVnode1.firstChild.nodeValue);
myDIVnode1.onclick= function() { somefunc(myDIVnode.firstChild.nodeValue); };
function somefunc(param)
{
// this returns "undefined" !!??

I am writing a Javascript to sort and write out some stuff. PHP is not an option so I need to get this script working.
The problem arises when I want to make a link to the next page. (i.e. Like the link in Google for the next 10 results)
I have <a href=# onclick=FUNCTION(VALUES)> written dynamically by the script.
It is written onto the document correctly, but the problem is, when the link is clicked, some seemingly random values are passed to the function.
When you run the code, the first alert will show all the values that a were passed to the function. The second and third will show what was written to the document.
If you try clicking the next button after the code loads, the values that result will be unusual.

How do i use a function to find the average of the values in an array of numbers passed as argument to a function.(using java script) thank you for your help...
View 1 Replies View Relatedhow would i build a multidimensional array? would it be: PHP Code:
var rinksAndPriceArray = new Array();
rinksAndPriceArray[0] = new Array();
rinksAndPriceArray[1] = new Array();
i've figured that out so far.
now, i want to be able to access a part of one of the arrays based on a variable that is passed into the function
the variable i'll send in will be the first part of the array ex: rinksAndPriceArray[0][0] and i'll want to return the rinksAndPriceArray[0][1] value.
I have a function that sends some data to a PHP file for processing, and call a page refresh after that, but it's not working. This is what I have so far:
function Reload() {location.reload() ;}
function del(v,m,f){

javascript:parent.mainFrame.document.location.reload();
}
The function Reload is something else I tried while trying to get it to work but everything I have done so far doesn't work. :(
I want to run a function only if it has been called from lets say another function, is there an event handler for that? I dont want to call the function on document.ready since it will load without being called?
for example, the below function is run when page loads, how do I just run it only when I call it directly, say from another function..
$(function() {
$( "#progressbar" ).progressbar({ value: 0 });
});
I'm trying to run this script on Firefox. I'm copying and pasting the whole thing in here just to be safe, but I'm mostly concerned with getting the findLegendary function to call catchPok(). The script executes fine, goes into the battle, but then...does nothing.It runs the catchPok function if I manually click and deselect the "Find Legendary" window option, so alternately, if somebody knows how to make the program automatically click the element at that point to stop repeating the function (maybe?) and it works, I'd be just as happy with that. My best guess is that the autoContinue function might be interfering somehow, since it runs that portion of the code with the manual findLegendary shutoff, but to be honest I'm pretty clueless.
What I want it to do is run the catch function through, catch the game pixel, and then go back to repeating. I don't care how this is accomplished as long as it can feasibly loop. The game rules allow botting, so this isn't against any site rules, either.

I have an image that I have given an onmouseover event to like so..
Code:
<img id="1" alt="" src="images/image.jpg" onmouseover="highlight()" />
<img id="2" alt="" src="images/image.jpg" onmouseover="highlight()" />
what I would like to know is - within the highlight function what ways are there of getting the id of the image element that called the function? I was thinking I could declaritively pass the id to the function like so - onmouseover="highlight(1)". or would onmouseover="highlight(this.ID)" work? Or is there a better way of getting the id of the calling img element from within the highlight function, I'm thinking that perhaps there is a sender object that I can make use of that I don't know about, if so how do I use it?
I stumbled over a strange behaviour of Mozilla. When I want to access the
caller property of a function that was not called from within another
function, Mozilla seems to abort the script. No error message, no hang, just
stopping script execution at that point. Why? And what is the remedy?
