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>

[Code]....
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.

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 get a endless loop going, for example for looping continually through a group of photos. So what I have is:
$(function(){
var ima = Array("johnny_100.jpg", "beau_400.jpg", "mofat_400.jpg");
$.each(ima, function(index, val){

so basically how could I reset the index, or maybe there is a better way to make an endless loop?
I'm familiar with Java so I shouldn't be too lost. What I'm about to do is add support for a web app from Firefox to IE that uses OpenLayers.
I've searched and found a link to this site from another thread which had a list of supported functions and what not here: [URL]
From what I've read in the last hour it seems as though I will have to use some browser sniffing (isMozilla, isIE8, etc) and have multiple conditions (if-else's) in my functions to use the proper calls. Does anyone have extra material that contains differences between IE and firefox? Someone mentioned to me that in lists IE doesn't support trailing commas but ff does..
Does anyone know why the following code would work perfectly in FireFox but error out in IE7?
function readPageNumber() {
var split1 = document.cookie.split("=");
var split2 = split1[1].split("/"); <-- This is the line that errors
var split3 = split2[4].split(".");
var page = split3[0];
return page;
}
The error reads:
Error: Ƈ' is null or not an object.
So why does FireFox execute the code correctly and IE7 does not?
This is what im trying to achieve. At the top of my page there is some
search functionality, through which you cause to be loaded a string
representing an HTML page. Below this and occuupying about 80% of the
window real estate, there is a DIV. There is also a toggle button with
two options "Code View" and "Text View" as I have named them. Depending
on which mode you are in, you can see the block of HTML either as code
(in other words the tags are not rendered. You see the HTML as it
exists.) or as text (rendered HTML). Consider the following code, which
is a simplified version of the page.
<script language="javascript">
var mode = "code";
var s = "<html><head>
<style type="text/css">
My Stylesheet
</style>
<title>
MyTitle
</title>
</head>
<body>";
function ViewDoc()
{
if(mode == "code")
document.getElementById("docArea").innerText = s;
else
document.getElementById("docArea").innerHTML = s;
}
function ChageMode()
{
if(mode == "code")
mode == "text";
else
mode == "code";
}
</script>
<HTML><BODY>
<table>
<tr>
<td>
<input type='button' onclick='ViewDoc()' value='View Document'>
<input type='button' onclick-='ChangeMode() value='Change Mode'>
</td>
</tr>
</table>
<div id='docArea'/>
</BODY></HTML
The variable s contains an actual example of some HTML im trying to
load here (with the contents of the stylesheet omitted.)
Now, the following works fine in Internet Explorer. It does not work at
all in Mozilla Firefox. In firefox, for example, I have to cut out the
stylesheet, or the entire page goes fubar. Without the embedded
stylesheet, the "text" view (rendered html) works just fine. But the
"innerText" does not work in Firefox, and im not sure how to replicate
it.
Is AJAX built on top of JavaScript? What browsers supported AJAX?
View 6 Replies View RelatedIn Firefox 2, document.getElementById is returning an HTMLDivElement,
in IE 7, it is returning an Object.
For example:
<div id="errorTableDiv">
</div>
....
errorTableDiv = document.getElementById("errorTableDiv");
alert(errorTableDiv);
errorTableDiv.appendChild(someTableNode);
Firefox prints HTMLDivElement and lets me appendChild() later on
IE prints Object and gives an error on the appendChild()
I do not understand why this happens or what the most socially
acceptable way to fix it is.
Mozilla/Firefox seems to be wrong when rendered elements with sizes
given in percents and that are placed into another elements with
percentage sizes, if the content overflows them (of course, overflow is
set to the value of "scroll")
To check the written above please use the given below code:

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>
