I am not sure of the exact way to do it. <html> <head> <script type="text/javascript"> var checkLink = function(linkId, enabledFunction){ var linkidObj = document.getElementById(linkId); if(linkidObj.className=="activelinktext" ) { enabledFunction(); return false; } else if(linkidObj.className=="inactivelinktext") { return false; } alert("*inside CheckLink*"+enabledFunction); }; </script> </head> <body> <a class="inactivelinktext" onclick="checklink(this,"javascript:goback();")"> </body> </html> Thanks, -Vijay Ok, guys. I'm new to JavaScript, so go easy. I'll be asking bunches of "dumb" questions for a while. 1st question, and the only one for now ... Say I have the following function: Code: function SwapValues(SwapVal1,SwapVal2)
{
TempSwapVal=SwapVal1;
SwapVal1=SwapVal2;
SwapVal2=TempSwapVal;
}
I don't care about the return value of the function itself, but I do need the new values of SwapVal1 and SwapVal2. In ASP when I do this, the values get returned. How do I get this to work in JS? I have a simple function to display an image when called, but if I try to rewrite the function to take the image as an argument, it stops working. I've looked at other function examples on the web but can't figure out what I am missing. Can anyone help? works: Code: <html>
<script language="JavaScript">
var ImagePlusSign = '<img src="plus.jpg" name="slide" width="65" height="50"/>';
function FlashImagesThenWait()
{
document.getElementById("first").innerHTML = ImagePlusSign
}
setTimeout(FlashImagesThenWait, 1500);
</script>
<body>Hello.
<div id="first">
</div>
</body>
</html>
does NOT work : Code: <html>
<script language="JavaScript">
var ImagePlusSign = '<img src="plus.jpg" name="slide" width="65" height="50"/>';
function FlashImagesThenWait(z)
{
document.getElementById("first").innerHTML = z
}
setTimeout(FlashImagesThenWait(ImagePlusSign), 1500);
</script>
<body>Hello.
<div id="first">

Hi, 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> [/CODE] 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" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<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". Question 1: 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 Second and 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. NOTE: 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" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<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>
Question 2: can someone straighten me out with this? Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

My teacher insists that the above code is valid (straight out of our book). He says this because (I'm guessing) it runs okay in Firefox and other browsers. It also throws a ton of error messages in Chrome and makes no logical sense. We define the values of the jackhammer array as literal strings, and then the book instructs us to change the source of the image element on the page to jackhammers[i].src. It then has us change the source of the image element again, correctly at the end of the function. It also has us create a useless variable: "direction" (and I say useless because we never use it, it is just fluff I guess). On a side note, would some of you guys like to check out this animation I created here and let me know what you think. Thanks guys. Hi there, I am trying to pick the larger of 5 numbers and sometimes there is a tie. I would like to prioritize variable c1 if there is a tie. This data is from a quiz I am writing. var c1 = 2; // Takes priority if there is a tie. var c2 = 1; var c3 = 2; var c4 = 0; var c5 = 0; How can I call a PHP Function inside a Javascript Function? This is what I have so far, but I don't think I'm doing it the right way. Any suggestions? PHP Code: <?php function phpQuery(){ $query = mysql_query("INSERT INTO mytable VALUES('','name','email')"); } ?> <script type="text/javascript"> function delayQueries() { timeoutID = window.setTimeout(doQueries, 2000); } function doQueries() { var runQuery = "<?php phpQuery(); ?>"; } </script> I made a mouseover event of a caption on a picture, when I hover the opacity of the background color of the hover and the text goes down. What I want is that when I hover over the image which the caption is floating on, the onmouseover event gets activite. For an imaginary example: Code: function unhighlight(x) {
x.style.backgroundColor="transparent"
}
Function ActivationFuction()
{
activate.function="unhighlight"
}
thanks Hi everyone, I am pretty new at javascript OOP. I have a javascript file that has plenty of javascript functions, variables, arrays, etc. I need to convert this into an object. Here is an example: Code: var myvar1 = '';
var myvar2 = new array();
var myvar3 = new array();
var myvar4;
var myvar5 = 60;
var myvar6 = '';
function myfunc1(){
myvar1 = 'hello';
return myvar1;
}
function myfunc2(somenum=0){
myvar5 = somenum;
//calling myfunc1() from within this function.
//do something in here
}
function myfunc3(){
//calling myfunc1() from within this function.
for(i=0;i<somelength;i++){
myvar2 = myvar3[i]; (something to put into the array)
}
}
1. I need to create an object and put ALL the varibles (myvar1 - myvar5) in that object. 2. Then the first two functions "myfunc1 and myfunc2" inside the same object. 2. And the function myfunc3 needs to sit OUTSIDE my object as a regular javascript function. It calls on myfunc1 (which is inside the object) and also inserts data into myvar2 (which is classified inside the object) and myvar3 (which is classified inside the object as well). This is what i came up with, but it's not going well: Code: var myobj1 = function(){
this.myvar1 = '';
this.myvar2 = new array();
this.myvar3 = new array();
this.myvar4;
this.myvar5 = 60;
this.myvar6 = '';
var myfunc1 = function(){
this.myvar1 = 'hello';
return this.myvar1;
}
var myfunc2 = function(somenum=0;){
this.myvar5 = somenum;
//calling this.myfunc1() from within this function.
//do something in here
}
}
function myfunc3(){
//calling mynewobj.myfunc1() from within this function.
for(i=0;i<somelength;i++){
mynewobj.myvar2 = mynewobj.myvar3[i]; (something to put into the array)
}
}
var mynewobj = myobj1;
HELP.....!!!! i really want to get into object oriented world, so thanks in advance. If I use function or Function to create a javascript function, does it make any difference ? Whats the difference between two and in which situation shall I use either ? Likewise whats the difference between event and Event objects of JavaScript ? Thanks Hi I have a JavaScript function that has leaves floating around the screen and I need a way to have a checkbox turn on and off the function. Or I need a way to have a button turn off the script. I have the code to start the function on-loading the site. Any ideas are greatly appreciated. I got the falling leaves script from http://javascript.about.com/gi/o.htm...tip62.htm%3Ffm Hi, I have a javascript code in my site which is similar to this: var menu1=new Array() menu1[0]='<hr style="color: \'#FFCC66\'; height: \'1\'; text-align: \'left\'; width: \'96%\'"><strong><font size=+2>text1</font></strong>' var menu2=new Array() menu2[0]='<hr style="color: \'#FFCC66\'; height: \'1\'; text-align: \'left\'; width: \'96%\'"><strong><font size=+2>text2</font></strong>' The list goes on for hunders of records. What I need to do, is to use a function in which I will pass the text1, text2, text3 as variables, and have the html code returned, since it's always the same. For example, I would need something like: var menu1=new Array() menu1[0]='display_html(text1)' var menu2=new Array() menu1[0]='display_html(text2)' This would save me a lot of bytes in the output file, but I'm not very familiar with javascript so I didn't manage to make it work. I tried using the document.write command in a function, but that forced the text to be displayed on my page, even though it was supposed to be shown only when the user clicks on a link. I'm using the "AnyLink Drop Down Menu" script from www.dynamicdrive.com. Any help would be highly appreciated! Please I have been having sleepless nights for days and could not resolve why this codes will not work. I will appreciate any assistance to resolve the coding reerroll the main problem is the function calculate (), does work when called.

I'm trying to get some basic javascript down so I can have my text come in from both the top and the bottom of the screen when the page loads. It's working just fine in Firefox, but in IE it stops with an "invalid argument" error. The problem comes on this line: Code: document.getElementById('part1').style.top = down[part1Position] + "px";
Here's the whole code in my separate .js file. Code: var part1Position = 0;
var part2Position = 0;
var downPosition = -19;
var upPosition = 800;
var down = new Array();
var up = new Array();
for(var i = 0; i < 91; ++i) {
down[i] = downPosition;

Any help would be greatly appreciated! I'm stumped. The Javascript function change() in not getting called by onClick event of button Click Me ,JavaScript array size has been created in PHP Code: <html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script type="text/javascript" language="javascript">
function change()
{
alert(size[1][0]);
}
</script>
</head>
<body>
<script language="javascript">
var size = new Array();
var = count;
for (count = 0; count < 5; count++)
size[count] = new Array();
size[0][0] = 600;
size[0][1] = 400;
size[1][0] = 300;
size[1][1] = 400;
size[2][0] = 300;
size[2][1] = 400;
size[3][0] = 600;
size[3][1] = 400;
size[4][0] = 300;
size[4][1] = 400;
</script>
<input type="button" value="Click Me" onClick="change()"/>
</body>
</html>
