For In To Iterate Sparse Array
Jul 10, 2007I know that using for in loop to iterate over array elements is a bad
idea but I have a situation where it is tempting me to use it. I have
a two dimensional sparse array say "arr" which will have length to be
some 50 but will have some elements like arr[1], arr[10], arr[23] at
random locations. Each of these elements is again an array (since it
is two dimensional) say arr[1][30], arr[1][24] & so on for arr[10 &
23] also. Currently I've coded it like this:
for (var i = 0; i < arr.length; i++) {
for (var j = 0; j < arr[i].length; j++) {
if (arr[i] && arr[i][j]) {
// do stuff with arr[i][j]
}
}
}
but i am tempted to do following
for (var i in arr) {
if (!arr.hasOwnProperty(i)) {
continue;
}
for (var j in arr[i]) {
if (arr[i].hasOwnProperty(j)) {
// do stuff with arr[i][j]
}
}
}
thinking it to be faster. What are your views?
JQuery :: Cannot Iterate Through Table
Dec 3, 2010I am loading a Html table through jquery ajax. In this table each row has a check box . when i click the check box i want to get all the details in the row. but i could not iterate through the table.
when i use $("#civilBillTable1 tr[class="+row+"]" ).each(function(){}); works perfectly, but the table is not loaded through jquery ajax
if i use below code, it will not work
$('input.chkAddItem').live('click',function(){
var itemId,description,unit,rate;
$("#civilBillTable1").live()('each',function(){ // the table is loading through Ajax

Iterate Through An Array Using CharAt?
Sep 14, 2010In this program i attempting to iterate through an array using the charAt () function and then store these element positions in a new array called elementPositions.
The user selects a flightDestination from the flightDestinations array which is stored elsewhere, and what my program needs to do, is find all the array elements positions where the same flight destination name occurs in my array.
I then need to store these positions so i can use them elsewhere, and i'm pretty sure i need to use charAt() but i think my syntax may be wrong - contained in the for loop.
var yourDestination = readTheDestination();
var title = "<B>" + "You asked about Flights to " + "<B>" + "<BR>";
var flightInfo;
var solution = "";

Iterate Through An Anonymous Array?
Oct 11, 2009Is it possible to iterate through an anonymous array of strings with a for loop?
Here's what I'm trying to do:
for ( i in ['country', 'city', 'state'] ) {
doSomethingWithString(i);
}
What I want is the string, but what I'm getting is the index number of the array, which I can't use because the array isn't named.

Iterate Through Input Tags And Get The Ones?
Nov 20, 2010I have a problem in Javascript that I really cant figure out, I've tried for days! here it goes: I need to iterate through a form and get all the elements that has a class like "required" and then, save this elements id, because I have label elements that has a for="" tag with the same as the id for the input/dropdown in the form. To all these labels I need to apply a "*" in the end of the label. And all this in an onload function.
I have tried everything I can come up with but now I'm close to giving up so now I need help, how can I get these values and do this?
JQuery :: Iterate Through All The Dropdownboxes On A Page?
Sep 4, 2010I'm trying to iterate through all the dropdownboxes on a page without much success! What I'd like to do is store the selected value for each of the dropdowns, separated by commas in a variable when a button is clicked. Each of the dropdown boxes 'id' begins with the string 'attrib-' which is how I'm trying to identify them.
I've managed to hide all the dropdowns with this code:
jQuery(document).ready(function() {
jQuery("#myButton").click(function() {
jQuery("[id^=attrib-]").hide();
})
})
So I thought I could do something similar to get the selected value but I can't figure it out.
JQuery :: Iterate Over A Checkbox Group?
Jan 29, 2011I have a form on which I've created 5 checkbox groups. Each of these groups consist of multiple checkboxes. The first group - it's id equals "MASTER" - contains 4 checkboxes. These checkboxes are labelled (that is, their actual label tags are) "A", "B", "C", "D". My vision is to have a user check, say, "A" in MASTER and this causes the "A" checkbox group to appear below the MASTER group. If a user then checks "B" in MASTER, then the "B" group appears below the "A" group. If the user then unchecks "A", then the "A" group disappears. And similarly for each of the four "subordinate" groups. My plan of attack was to iterate over the MASTER checkbox group, and for each checked box, somehow populate an array of their associated label tags. I would do the same for all of the checkboxes in MASTER that are not checked, placing their label tags in another array. I would then show and hide the subordinate checkbox groups based on these label tags. The subordinate groups have label tags equal to these captured label tags in these two arrays. All of this action would be triggered via a "click" action on the tag in which the MASTER group resides. I've tried all manner of techniques, including "$.each" and ".map" to populate arrays. I just can't get my mind around the needed syntax.

Jquery :: Iterate Certain Classes Over Elements
Dec 21, 2010In my page I have pairs of divs like this:
Code HTML4Strict:
<div class="rounded red">
<p>Integer egestas neque vitae dui ultricies vel venenatis mi varius! </p>
</div>

This works,in that it at least added the new class whereas the other solutions didn't. Unfortunately it counts EVERY div, not just the ones with the class .client, I can't set my array of desired classes, and I have no idea how to make it restart the count after it hits #4.
Iterate Over Objects In Internet Explorer?
Feb 9, 2010Is it possible to iterate over user-defined objects in Internet Explorer? Iterating over objects in top in Firefox (v 3.5) finds user-defined objects, but it does not in Internet Explorer (v 7).
Code:
function myFunc() {}
for(var obj in top) { alert('objname=' + obj); }
In FF the above will find myFunc, and in Internet Explorer it will not. Should I be checking a different scope?

Jul 16, 2009As soon as the page loads, I would like to iterate through several span tags on the page and update their innerHTML to be the response from the AJAX get call. The line I have commented out, alert("Data Loaded: " + data);, works perfectly, but creates a bunch of alert boxes (which I don't want). And if I move the line "this.innerHTML =data;" out of the Ajax call, it works fine also. So I know all the syntax is correct. But when I put it together as outlined below, it just won't work. The Ajax is working, I also see the GET calls working fine in the Firebug console. It just won't update the innerHTML of the SPAN tags.

JQuery :: Each Function Iterate Through Form Inputs
Oct 23, 2009I cant get this each function to work inside a form: For example I have this code:
$('#formid>input').each(function(){
if($(this).attr('id')!='') alert($(this).attr('value'); //fetch id if
not blank ang show value
});
The code inside this function does not run if the form is rendered this way:
<form><div id='tabs" >
<ul>...</ul><div id='tab1">
<input type='text' id='fname' /></div>
</div></form>
But if it is rendered in a simplier way like this, it works:
<form><input type='text' id='fname' /></form>
I am using jquery jquery-ui-1.7.2.custom.main.js library by the way for the tabs but I don't think that messes up the whole thing though...
Iterate Through A Table For Values Of Drop Down Menus?
Dec 22, 2011I wish to get the values for the 3rd and 4th cell of each row where these contain drop down menus. I've tried various ways but my code doesn't seem to iterate through rows of a table. I can get the values for the first row, but not the rest. There's isn't a fixed row size for the table as the user will be able to add and delete them.
I've put the values in separate arrays but instead of the array containing say [10, 20] it contains [10, 10] as it just duplicates the first row's values.
Here's my code that I have so far:
function calculate(){
var len = document.getElementById(arguments[1]).rows.length;
var cMenus = [];
var gMenus= [];

I've tried adding j to the arguments or putting it in "[]" but nothing seems to work. I don't think the platform I'm using supports jquery,

Iterate Array And Grab X Numbers Based On Pointer?
Jul 1, 2009I'm trying to figure out how to do this via Javascript.
Lets say I have an array like so:
var myArray = [11, 33, 44, 23, 32, 43];
var finalArray = new Array();
And I have the following variables
var lastNumber = 33;
var getNext = 2;
I want to use the lastNumber for a starting point in the array and then based on getNext, grab the next x numbers that getNext specifies and shove into finalArray.
That case moves forward in the array.
Second case would be the opposite, get the previous x numbers based on getPrevious in the array. So I'd start at lastNumber and then grab x numbers before it based on getPrevious.
var lastNumber = 33;
var getPrevious = 2;
I'm not sure if you can traverse backwards in JavaScript. But more importantly I'm not sure how to point to lets say 33. How can I do myArray[1] essentially based on I'm pointing to 33 and then how can I grab the next x in myArray ?
JQuery :: Using JQuery.each() To Iterate Through An Array Of Objects
May 5, 2010I'm trying to interate through an array of objects. Here's my code:
$('form').submit(function(){
var serializeArr = $(this).serializeArray();
jQuery.each(serializeArr, function(i, obj){
alert('Hi');
}
});
However, this just fails. It seems like its getting stuck on the serializeArray aka an array of objects. I've gone the for loop route and it worked fine up until I started doing some ajax stuff...the variable binding behavior was all over the place and unusable.
JQuery :: Use Plugins Dynamically - Make The List Dynamically Calling A JSON File ?

But when I tried to make the list dynamically calling a JSON file, does not works fine.
If I insert theready(fn) mentioned above inside the javascrypt function that create dynamically the element<ul >as is shown next:
Improves a little bit, but still does not work fine. Specifically does not show the plus and minus sign, then I can not open or collapse it.
I tried also with thecheckboxtree pluginand I encountered the same problem.
Dynamically Change Row Colour On Dynamically Generated Table Rows
Nov 25, 2005At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?
