For Loop - Looks Inside The Parenthesis - Assigns Count A Value Of 1

Feb 18, 2010

I am trying to understand the order of operations of a for loop.

for (count=1;count<3;++count)
{
document.write(count + ". nice rack.")
}

when this runs it prints:

1. nice rack.
2. nice rack.

I dont understand how it prints 1. The way I see it it sees the for looks inside the parenthesis, assigns count a value of 1, goes to the comparison sees that it is less than 3, then gets incremented by 1 at the next station, and then finally goes in the curly brackets and the string is written. So if it starts with 1, is less than 3, and is increased by 1. before it starts the loop, then the first sentence would read:

Send A Loop Variable (i) To A Function Inside The Loop

Aug 4, 2011

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.

Adding Open And Close Parenthesis (000) In The Phone Area Code?

Nov 16, 2009

adding a parenthesis in the area code of the phone number and validating it also. I made some javascript code but it is not working. I just need the code in adding () in the area code.

For example: When user enter 10 digit number no spaces or dashes such as 0000000000 or 000-000-0000, I would like to have this format right away (000)000-0000. I know how to replace the characters but adding it is a tricky one for me.

JQuery :: If Else Statement Inside Each Loop

Aug 3, 2010

I'm currently trying to produce an HTML table from an XML feed, using jQuery. And this works great! With an "each" loop, there now is a nice table on my screen, displaying the right information from the feed.

I would like for each new row of this table to have a separate color. For example:
row 1 - blue
row 2 - green
row 3 - blue again
row 4 - green again
...
and so on...

What I've tried, is putting something like this inside the loop:
var
x=0
(this line should probably be outside of the loop, but that doesn't seem to work)
if
(x=0)
code 1...
x=x+1
else
code 2...
x=x-1
But this doesn't work.

Make An Array Inside A Loop?

Feb 10, 2011

I have this loop:

for (var j = 0; j < gmarkers.length; j++) {
gmarkers[j].hide();
elabels[j].hide();
map.closeInfoWindow();

[Code]....

which was useful for passing the p variable when it was just one number.

but now I need to get that number every time j gets set (I understand that the j gets overwritten each time the loop goes through).

What would be ideal is if p could become an array, the contents of which match the values that j has passed though during the loop cycle.

I thought var p = new Array (j); minght do the trick, but obviously not...

Ajax :: Using To Implement Php Inside Of Loop?

May 7, 2010

I have a theoretical question, I can't really post my code. But I have four results from reads to a database using php. I then read from an xml file using javascript using a loop. I am basically creating a chart of four variables with several different values for each variable. Some of the values for each variables come from the database using php, and some come straight off the XML file parsing done by the javascript. I initially had the php fetch/extract inside of the javascript loop, but it only assigned the first variables values to all the other variables. I discovered (after hours of googling) the difference between client side and server side code. So, after all this typing, my question is where should I look for tutorials on using Ajax to be able to use php code inside of a javascript loop? (If at all possible)

Call A Function Inside A Loop?

Dec 27, 2010

I want to call a function inside a loop of an array but when I run it, it is only reaching the function the first time.

for (i in qMedia) {
writeMedia(qMedia[i].name, qMedia[i].format);
}

Even when I tried to call it outside the loop multiple times, it only executed once.

writeMedia(qMedia[0].name, qMedia[0].format);
writeMedia(qMedia[1].name, qMedia[1].format);
writeMedia(qMedia[2].name, qMedia[2].format);

I know that each of the objects in the array have data because I tried to run each one of the lines above separately without calling the other two and it worked fine.

Declaring/Initializing Variables Inside Or Outside A Loop?

Apr 30, 2007

I've always wonder if there is diference when declaring and
initializing a varible inside/outside a loop.

What's a better practice?
Declaring and initializing variables inside a loop routine, like this:

for(var i=0; i<list; i++)
{
var name = list[i];
}

or outside a loop routine, like this:

var i;
var name;

for (i=0; i<list; i++)
{
name = list[i];
}

or are both the same....

As a programmer, i always try to practice good programming. I always
thought that by declaring and initializing the variable inside the
loop, i was creating a new memory space every time instead of just 1
time...

What do you think?

Onmouseover Function Inside For Loop Not Working?

Apr 3, 2010

I have a simple HTML page with one DIV element with the id "rotator". Inside that, JavaScript is supposed to create boxes that react to mouseovers.

The weird thing is: The whole script works, but ONLY on the LAST box I create, no matter what I do. I can manually add the mouseover code to any one of these boxes, but it will only take on the last one. I can have JavaScript tell me the mouseover status of each box, and they all tell me they have code assigned correctly - but again only the last one works...

Here's the relevant code (yes, highly abbreviated, but it's the part that fails on me):

var maxBoxes = 10;
function initSite() {
var rotator = document.getElementById("rotator");
rotator.innerHTML = "";

[Code]....

initSite is called in the body onload. All kinds of other animation parts are implemented that work fine, just this mouseover won't work. I have tried re-writing it in multiple different ways, including "xyz.onmouseover = myMouseCode" and then defining the function separately later - still no dice.

So, the code creates 10 boxes (0-9) and 10 boxes that are on top of them to create a form of shadow effect depending on the position of the original boxes. Since the "myDark" boxes are on top of the "myBox" boxes, I apply the onmouseover onto the "myDark" boxes, but it only works on "myDark9" and no other box. They are all created the same way, the mouseover assigned the same way...

JQuery :: Calling A Program Using $.getJSON() Inside Of A For Loop

Dec 28, 2010

I am calling a program using $.getJSON() inside of a for loop. The problem is that the second callback doesn't wait for the first program to finish before it executes. Is it possible to ensure that the second iteration of the loop doesn't happen until the first one is finished?

buttons: {
"Import": function() {
var ids = $("#itemsGrid").jqGrid('getGridParam','selarrrow');

JQuery :: Setting Object Property Inside Each Loop?

Aug 10, 2010

Trying to add a new property to a non-jQuery object from inside each loop doesn't appear to work:
var arguments=new Object();
arguments['ticket']=ticket;
arguments['email']=email;
arguments['module']=module;
arguments['epoch']=new Date().getTime();

var total=0;
$('select.category').each(function(){
var name=$(this).attr('id');
var option=$(this).find('option:selected').val();
total+=parseInt(option);
arguments[name]=option;
});

The 'total' variable works as expected. The the 'arguments' variable doesn't. Almost like
a variable scope issue or something. If I put some extra debug code to print out all the
property/value pairs, outside each loop I only see original four, and inside each loop only
the new one just set and none of the original four.?

Swapping Out Tag Info With Onclick Dynamically Inside A Php Loop?

Sep 4, 2010

Below is the code.

My function:
function swap_content(id1,id2)
{
var tmp = document.getElementById(id1).name;
var theval = document.getElementsByName('primary_propertyp_id')[0].value;
document.getElementById(id1).name =

[Code]...

This is running through a PHP loop so it's making multiple divs and links for the secondaries. I am wanting to be able to swap out any of them to make them 'primary' this works for the first click, but after the first click it makes every div id and input name the same as the first that was clicked. It's also not working AT all if i click on the bottom link first, then a link above it. Top-down works, bottom-up doesn't..

JQuery :: Cannot Get Variable Inside Loop Back To Original Function

Oct 22, 2009

I'm having some problem with return value for a function. I'm trying to access google blogger's API to display blog entries on my site. I'm doing this through JQuery and requesting a JSON response. Everything seems to work ok, but I want to access the link for the blog entry. This is a subset of the "entry" object.

It's structured like this:
Entry:
title,
content,
link:
rel,
type,
href,
rel,
type,
href,

I want to get the link where the "link.rel == "self". To do this I have to loop through the link object (5 times). The loop and conditional statement works correctly, but I can't get the variable inside this loop back to my original function.

I have this code:
$.each(data.feed.entry, function(i, entry){
$.each(entry.link, function(j, link){
if(link.rel == "self"){
var postlink = link.href;
alert("link : " + postlink);
return postlink;
}});
alert(postlink);
});

Recursive Function With For Loop, For Loop Is Breaking When Calling Itself

Jan 22, 2011

I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.

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" : [

[Code].....

'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.
