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";
}
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"',....]
Is there a similar function in JS as the PHP foreach() loop?
foreach($something as $key => $value)
{
execute code here;
}
I have created an object in JS:
var ibm = new Object();
ibm[Ɔ'] = 240;
ibm[Ƈ'] = 241;
ibm[ƈ'] = 242;
ibm[Ɖ'] = 243;
etc...
and I want to access it as
if($key == $somthing)
{
$this = $this;
}
How do I create an array in JavaScript and then go through it?
I want to feed a function with the string "foo,bar,rab,oof" and want JavaScript to do something with each line, like this (in pseudo-code):
myfunc("foo,bar,rab,oof");
function myfunc(string){
foreach i (split(",", string)){
alert(i);
}
}
Or something like that.
i have added html elements at run time using append
function addFormField()
{
$("#inputss").append("<strong>abc</strong>");

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.
In http:www.dreaminco...wtopic51264.htm a code was proposed for generating a random number within an array and then printing it into the html document using document.write.Is it possible to go one step ahead and feeding the result into an html href function? [code]is the random array member generated by the javascript.

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?

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.

I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100.

When I used toFixed() method on a number, I thought that this method round a number to a specified approximation, but I got a surprising result, the number became string! 15.23689.toFixed(2) ==> "15.24". So does it convert the number into string?
View 6 Replies View RelatedI am trying to figure out how to make a random number I can plug into a script count down from that number at certain times of the day until it reaches 0. I would like it to reset itself at midnight every day. I'm trying to make it work with a script I found on here that resets itself at midnight every day. So instead of it counting down too fast, it would count down to the next number after a randomly generated number of minutes until it reaches 0. But it wouldn't necessarily have to end at 0 at midnight. It could go from 845 to 323 at the end of the day at a slower pace. Is that possible?
