Comparing Array Values To Select Unique Array Elements?
Apr 10, 2010This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.

Passing Values In Functions?
Dec 19, 2010Recently I decided to branch out and learn some Javascript on my own. I'm getting the following error: Uncaught ReferenceError: array is not defined
I don't quite understand why I'm getting this error, as I've created the array in the function showPrompt and it seems as though it's being passed around correctly. However, I believe the problem is with generateBoxes, specifically this part here:
onclick=\"getValue(array, i)\"
(line 39)
Removing array from the function parameter seems to make it execute, but beyond that, i'm lost to what is wrong.
Here's the code:
function showPrompt () {
Obtains user input
var array = new Array();
var box = prompt("Please enter number of boxes","1");

Getting The Default Values In Functions?
Sep 8, 2004I would like to call a function with parameters, i.e. multiply('2','3','box1').In this example, the first argument would be multiplied with the second and written into the div with the id="box1". How can I set a default value for the third argument? => so if I call multiply('2','3') then it should automatically set the output-variable to 'box1' if not other defined in the call.

View 2 Replies View RelatedFunctions - Passing In Parameters And Then Calling The Function With The Values To Maybe Add Something Together
Jul 27, 2011I totally understand that in order to learn javascript I need to know how functions work, I understand the basics of passing in parameters and then calling the function with the values to maybe add something together etc I ve read countless articles about functions as well as books etc but I just dont get how they are used and when they should be used etc, the more advanced functions that have maybe 4 parameters and are doing different calculations and returning various values that get fired back into the script just totally confuses me.
What I would like to know is first of all how can I overcome this confusion and also any words of wisdom you may have. I will also add that I have no prior programming experience and have spent the last 2 months frequently hitting my head off a brick wall as I just cant understand javascript.

JQuery :: Dynamically Declaring Functions - 'array' Variable Contains Strings Representing The Id's Of Different Elements
Oct 12, 2010Demonstration code:
The 'array' variable contains strings representing the id's of different elements. If the for loop above were to finish iterating, would all the links in all three elements call the click function (that displays an alert message), or would only the last element ("element3") have the click function? For me, the latter seems to be the case unless if I'm doing something wrong, but I would like clarifications and, if possible, alternative solutions as to how I can achieve the former result.
