Aug 17, 2010I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
[Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.

May 15, 2011I tried creating a global function to calculate the distance between 2 points.
jQuery.distance(p1, p2){
var dx = p2.x - p1.x;
var dy = p2.y - p1.y;
return Math.sqrt(dx^2 + dy^2);

View 1 Replies View RelatedMultiple Array And Display - Declare A Variable Named Total With An Initial Value Of 0
Sep 17, 2010I am looking for a push in the right direction for a few problems i am running into; my first problem is I have to create a script element that contains the function amountTotal which should return the sum of all the values in the amount array. There are no parameters for this function, and I have to add the following commands to it.
1. declare a variable named total with an initial value of 0
2. create a for loop thatloops through all of the values in the amount array, at each iteration of the loop, add the current value of the array item to the value of the total variable.
3. and after the for loop is completed, return the value of the total variable.
The amount array has already been created and populated in a list.js file, I had to first create a script element pointing to it.
This is what i had for my link to the list.js file and funtion :
I have my entire code written but i am trying to break it up and fix my problems 1 at a time: when i open the code, it does'nt display correctly ( which is another problem) but I ran the debugger and it says my total is undefined. ( this is in another section of my code), but I guess my function is wrong somewhere.

Possible To Declare A Default Value In A Function?
Jan 28, 2009How do i declare a default value in a function? I have a simple function
function color_input(id,token){
if (!empty(token)){
document.getElementById(id).style.backgroundColor = '#2A2A2A';
document.getElementById(id).style.color = '#DDC58C';
[Code]....
You will notice that the #2 parameter is missing in the html call. Sometimes i don't have it to send. in PHP i would just set the functions second param like token=''
function color_input(id,token=''){}
How do i set a default param in a JS function?
