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.

Decreasing Values Of An Array By One Where Value > X?
Apr 4, 2009I have an array similar to this:
Code:
0 -> 0
1 -> 5
2 -> 9

[Code].....
There is no clear logic and that does not matter. I need to decrease the values of those by one where the value is higher than x. How would I do this?

0 -> 0
1 -> 5
2 -> 8

Now what i want it to do is every time the for loop runs the if statement checks whether the SEARCHID variable is not equal to the values in the IDCONTAINER array....if this is the case then the code after the if is run and the value in the SEARCHID variable is added to the IDCONTAINER array.
Problem is i dont know how to structure the if statement to check all the values in the array against the SEARCHID and then i dont know how to update the array afetr the if with the new SEARCHID.

Getting A Collection Of Form Values Into Array
Nov 11, 2011'm having a very hard time making this work and be happy in both IE and Firefox. Basically, I'm setting a timeout to get an array of the form values if not present, or compare against if they are present, and if any change in values, submit the form to auto-save it.
below is my coding, basically I am using document.forms[thisformname].elements - but that gives me a lot of things that are NOT form fields and I just need to read input:text, input:checkboxk, input:radio, textarea, and select elements - nothing more. I'm open to any suggestions and some of you smart guys could probably write this in half the lines I did.
Code:
//auto-save coding
var autosaveTimelapse=0;
var autosaveTimeout=3; //every n seconds

Validating Array Depending On Values
Aug 11, 2009I have two arrays that are tied together Ink1Data[][InkID] and Ink1Data[][Ink1Desc]. I also have this Javascript code to validate it:
var chksink1 = document.getElementsByName("Ink1Data[][InkID]");
for (var i = 0; i < chksink1.length; i++) {
switch (chksink1[i]) {
case (chksink1.value=1);
var i1Desc = "Ink1Data["+i+"][Ink1Desc]";
if (validate_required(i1Desc,"Please fill in a trim size.")==false)
{i1Desc.focus();return false;}
break;
case (chksink1.value=2);
var i1Desc = "Ink1Data["+i+"][Ink1Desc]";
if (validate_required(i1Desc,"Please fill in folding instructions.")==false)
{i1Desc.focus();return false;}
break;
case (chksink1.value=3);
var i1Desc = "Ink1Data["+i+"][Ink1Desc]";
if (validate_required(i1Desc,"Please fill in scoring instructions.")==false)
{i1Desc.focus();return false;}
break;
}}
Basically, I want to count how many are in the array (will be the same number for both) and then depending on the value of the first array, validate the second and kick an appropriate error if necessary. It should be pretty easy, but I can't seem to get the code to work.
