Loop Elements By Name?
Sep 14, 2010
Ok so I have these elements on my page:
<input type="text" size="5" name="val[]" value="'.$NotaMaxima.'">
I want to loop through each one and take their number add it to another number set in a variable elsewhere and then alert that number.The amount of these elements on the page changes constantly, so I can't count on that. It has to loop through each one to find the values.I tried this:
var els,i,asig;
els=document.getElementsByTagName('val');
for(i in els) {[code]..........

I have a dynamicly generated form (well the elements are at least) that looks something like this:
while( not end of returned records):
<input name="plan_id[]" type="checkbox" id="" value="<?=
$row_plans->planid ?>">
<input name="num_of_pockets[<?= $row_plans->planid ?>]"
type="text" id="num_of_pockets[]" value="<?=
$row_plans->num_of_pockets ?>" size="5" >
endwhile;
Basically it loops thru the table and creates a row of fields in the form that use the array identifiers '[]' so that I can loop thru them with PHP when the page is submitted.
The key for each array element is the id of the row from the database. So checkbox[] (with value "1") and cost[1] are on the same line in the form. The next line may not necessarily have cost[2] in it, it may be cost[3] or [4], depending the id from the database.
Is there some way I can loop thru these form elements in javascript?

I have dynamically created divs. Their ids all start with 'info':
<div id="info1a"></div>
<div id="info1b"></div>
<div id="info2a"></div>
<div id="info123456"></div>
I need a function to loop through all those ids starting with 'info' to put the display property to 'none'.
Code:
document.getElementById(startWithInfo).style.display='none';
Is there any way I can do that withoput having to specify the full id for every div that starts with 'info'?

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 know that it may be better to use the .each() function for this but I can't figure out how to iterate over elements that or not children or siblings of $(this). I have this code, and it works fine:
$('#button1').hover(function(){ $('#pres1').css('opacity',1.0).siblings().css('opacity', 0.0); });
$('#button2').hover(function(){
[Code].....
But that doesn't seem to work for some reason. I can't figure out why (still early days in JavaScript for me).

Can someone explain to me the best way to loop through the geocode and marker (google maps) part of this code for all of the elements with the "address" class using jQuery (or javascript if need be). I tried wrapping the contents of the codeAddress function in $(".address").each(function () {... and replacing the getElementById with a jquery selector, but I still seem to be lost.
[Code]...

I have a ASP.NET gridview which is rendered as a HTML table. There are 2 columns in the grid. First column is a checkbox and second column is a input textbox in which the user will enter a amount. I want to be able to loop through the rows of the table using jquery to find out the rows that have a checked checkbox and then sum the value in the corresponding textbox in which the user will enter a amount. In other words how do I loop through the table and find out the elements on the same row on the table.

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.

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.

I am doing some studying and we was to create a small loop using either the for loop, while loop or do while loop. I chose to do the for loop because it was easier to understand, but I want to know how to do the same using the while loop. Here is the for loop I have, but I cant figure out how to change to while loop.
for (var i = 0; i < 5; ++i)
{
for (var j = i; j < 5; ++j)
{
[Code]....
How do you make the same using a while loop?
