Long Number To Array?
Feb 7, 2011
How do you take a long number such as Math.PI and break it out into an array? code...
I suppose that because of the decimal you would have to convert it into a string first? It would be ideal if I could keep the number as a number without converting it to a string, but I'm not sure if that's possible.
Every thread I've found online so far seems to indicate that you need a delimiter between the string you want to split up - that you can't just put every character of a string into an array... but there must be a way.

What is the correct syntax for an nested array where each array element has 3 elements, a number and two text strings?
Code:
array = ['1, Old Man, Old Man','2 Black Sheep, Black Sheep',....]
should the text strings be in double quotes("")?
Code:
array = ['1, "Old Man", "Old Man"','2 "Black Sheep", "Black Sheep"',....]

i can scoured but cannot find a way to simply iterate an amount set by a number. both .each() and for(); seem to require the length of an array.
in php you can say if(startNum; is less than or equal to toNum;plusOne) but that doesn't work the same way. is there any way to iterate through something like this, using the javascripts for loop?:
Code:
var quantity = 20;
for( i=1; i <= quantity; i++){
return "blah blah";
}

I just want to create an array of numbers counting from 1 to a given number.
At the moment I have the for loop running like this:
var i=0;
for (i=1;i<=10;i++)
{
if (i == 1)
[Code]....
This outputs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
How can I put this output into this variable: 'var ids' so I get out
var ids= [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

I have a function that requires the ability to count the number of entries in an array.
I'm using the following to call my function inside an input tag:
Here is the javascript:
And when errors.length is alerted, it outputs 0. I can only figure that there is an issue when using custom named keys in an array, since this works when I use only integers, however, I have the need to use a custom key index as shown.

I have a form element that looks like this:
<input type="text" onchange=doSomething(this)>
and a function:
function doSomething(theField){
}
I know that within the function I can access properties of the field (e.g. theField.name and theField.value). But how do I access theField's index number in the form's elements[] array -- from the "this" reference that was passed to the function? I.E. if this field is elements[3], how can I get at that 3?

To edit or modify a bookmarklet code, it must be in the form of a multi
line code in a html file or a js file.
But to test or run the bookmarklet, I need to do three things:
1. go to online bookmarklet builder site
2. paste my (multi-line) code there and generate bookmarklet link
3. drag it to toolbar
And I need to go thru these tedious three steps several times because
developing a long bookmarklet (like MyPage) is not like:
write code -test it -done.
but it's like:
write code -test it -it doesn't work. -modify code(put debugging
code) -test it -it still not work -modify code -...
How do you get around with this tediousness? Is there a way to skip the
three steps?

When updating our agency's webpage daily, [URL] I am looking for a shortcut to save time.. When I update air quality numbers. I have to put the conditions. Ex.. 50 = good 100= moderate etc etc. As you see here(bold and underlined)
[Code]...
Well instead of having to type good or moderate every-time to correlate with the numbers, I want to find a way the category can automatically default correctly when I put in just the number. Ex, if I put in the number 100, it automatically knows to issue/ put Moderate with out me having to type it. I semi wrote a code .. Yet can't seem to know how to execute. Seeing if Maybe I can get some assistance.
