I have a loop that is running and I am trying to increment a number by one each time. Here is what I am doing, but each time it just writes out 1 for the value.
var i=1;
Start of Loop
document.write(i);
var i=i++;
End of loop
It just writes out 1 each time though.
I have written the follow code. It is meant to (when finished) output a table showing each member of the array PEOPLE. There Income ,there Tax bracket and there finally there total tax paid.The calulations in the if-else statements are correct.I have to create a loop that will go through the if else statements equal to the amount of the people in the array (This is no problem I have done this earlier)
My problem is when I try to add each element (PEOPLE) to the table or there indivual tax outcomes.Can I create a loop and increment in the elements each iteration to put on the table?(for there names) As I am not meant to store each iteration,it is to write to the table each time.This is the code I'm working on with out the loop.

The following code results in the exact same output. Is there an advantage to using i++ over ++i (or visa-versa) in the loop? :confused:
<script type="text/javascript">
var tarr1 = []; for (var i=0; i<10; i++) { tarr1.push(i); }
var tarr2 = []; for (var i=0; i<10; ++i) { tarr2.push(i); }
alert(tarr1.join(',')+'
'+tarr2.join(','));
</script>

I do mostly PHP/mySQL development.
I put some HTML together to gather a user's language abilities. Originally it was a multi-select box that pulled a its values from a mySQL table and, upon form submit, a PHP script posted the languages selected into an array and then pushed into a mySQL table.
Then the client decided he wanted the user to enter in the number of years/months they studied each language selected. He found someone on RAC and they gave him this code below. Which works, but doesn't integrate well with my PHP-array loading code. The client paid the RAC before I was able to test.
It's actually more complicated than that (with Fluent/Passable options), but once I know how to change the loop from the increment to an array, I'll be able to solve the rest.
What's happening now is the JS is looping, creating ids, fluentLanguageTimeQuantity_0, fluentLanguageTimeQuantity_1, fluentLanguageTimeQuantity_2, etc for each selection. Instead I'd like it to create an array fluentLanguageTimeQuantity[] with the selections loaded into it.
Code:
for(var i=0; i<options.length;i++){
fluentStr +='<div class="languageOption"><label>'+options[i].value+'</label> <input type="text" size="3" maxlength="3" id="'+

I'm trying to write some jquery that when a link is clicked it adds a number into a div.

Everything works fine except for the counter/adding on to theName ( newField[i].name = theName + counter). I know exactly what the problem is... I just don't know how to fix it. If I remove the li tags, the counter will work fine and increment each "name". As soon as I put the li (see code above) tags back (or any html tag - I have tested others as well) - it breaks again and won't increment the name - it just submits the names without numbers and alas I have no usable post data. how to keep the html formatting there and still get the counter to increment the name?

Im looking to increment a value of a Lable when an image is clicked.
e.g. if the label contains 1 and the image is clicked, the label should be changed to 2.
Iv'e got a page that has a mass amount of input fields, all of which require
a decimal figure. To make it easier when it comes to inputting data, I'm
trying to setup + and - links that will increment/decrement the form field
value by 1 when clicked.
I'm using the following code, however when I click on one of the links, I
get the following error -
document.forms.tmp.input_field is null or not an object.
It's as if JavaScript is not reading the parameter being passed through the
function.
Here's the code -
<html>
<head>
<script language="JavaScript">
function increment(input_field) {
document.forms.tmp.input_field.value = document.forms.tmp.input_field.value
+ 1;
document.forms.tmp.input_field.focus();
}
function decrement(input_field) {
document.forms.tmp.input_field.value =
document.forms.tmp.input_field.value - 1;
document.forms.tmp.input_field.focus();
}
</script>

What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
Here is the test object:
test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [

'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.
I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.
