Get Rid Of List Number When Using Unshift Method?

Nov 11, 2011

So im working on code that user adds things to a list. When you hit the promote button, the user chooses which task to promote to the beginning by way of the unshift method. My problem that I can't figure out is how to get rid of the number to the old task that I promoted. It's like its an empty string.[code]...

Number.toLongString() Method For Extremely Large Values

Feb 1, 2003

The standard Number.toString() method returns values in scientific notation once they exceed 10^20. In many cases, this is not an expected or desired result.

The toLongString() method provides a solution by always returning a literal numeric value regardless of the number's size. However, the value returned will not be accurate beyond the first [log base (radix) of (10^15)] digits.

radix: Optional. A number between 2 and 36, inclusive.Number.prototype.toLongString = function(){
var radix, n = this, d, t = '', p = ''
if(arguments.length>0 && typeof(arguments[0])=='number'){
radix = Math.round(arguments[0]);
if(radix<2) radix = 2;
if(radix>36) radix = 36;
} else {
radix = 10;
}
if(n < 0){
n *= -1;
p = '-'
}
while(n > radix){
d = n % radix;
n = (n-d)/radix;
t = d.toString(radix) + t;
}
return p + n.toString(radix) + t;
}

Mar 25, 2010

Is there an efficient way (ie. not looping through all members and counting) to find out what number an li will get in an ordered list? For example: [code]...

Naturally #first and #second will be 1 and 2, respectively. Without looping though all children of ol and counting, can I determine the number for #first and #second?

JQuery :: FadeIn Dynamic Number Of List Items One At A Time?

May 12, 2009

I'm loading another html file full of list items. What I would like to do is hide() the content right after it's loaded, and then fadeIn(0 each individual list item one at a time.

The problem is, it's loading all the list items at once. I don't know what to do. I could code the chain manually, but only if I knew the number of items in the list would never change. I'd really rather set it up to fadeIn any number of items dynamically.

Here's my code, which I know doesn't work, but maybe you could see what I am trying to do:

function loadContent(location) {
$('#content').load("assets/content/"+ location).hide();
var x = $('li#content').size();
var y = x - 1;

Jquery :: Building Dynamic List Of Items - Adding Index Number?

Feb 17, 2009

I want to build a dynamic list of items with jquery but am unsure how to add an index number to each of the items i create so that i can reference them to edit or delete them for example. So far, I have the following which just creates the items and appends or prepends them to the element depending on whether one item exists already. I just need a way of adding an attribute so I can then reference the current item when clicked and remove it. What would be the simplest method to use?

//create list items
if ($('.mylistitem').length) {
$('.myList-box').prepend('<div class="mylistitem"><div class="mylistitem-image"><img width="30" height="40" src="[URL]"/></div><div class="mylistitem-title">' + title + '</div><div class="mylistitem-options"><a href="javascript:removetitle();">Delete From List</a></div>');
} else {
$('.myList-box').append('<div class="mylistitem"><div class="mylistitem-image"><img width="30" height="40" src="[URL]' + titleid + '"/></div><div class="mylistitem-title">' + title + '</div><div class="mylistitem-options"><a href="javascript:removetitle();">Delete From List</a></div>');

JQuery :: Determine If Autocomplete Returns An Empty List And Number Of Records Returned?

Jun 5, 2009

While using jQuery, I found that I needed to know how many records were returned and also if the result set returned was empty. After searching the jQuery documentation I couldn't find any property or method that returned this value, so I've added that functionality
myself and wanted to share it with the group.

1) Determine the number of records returned: I wanted to show the user how many results were returned after they start typing into the autocomplete field similar to how Google indicates the number of results found when you start typing in the search box. At first I thought the max parameter in the function formatItem returned this value. However, it returns the max option that you set it to. So if your query returns 100 records and you set max to 25, it'll obviously return 25 (not what I wanted).So after trying various things, I looked at the jQuery code and simply added the number of records returned by the database to the formateItem function. In the fillList() function around line 660 I added the data.length parameter:

var formatted = options.formatItem(data[i].data, i+1, max, data [i].value, term, data.length);And in my autocomplete code, I added the parameter to the end of theparam list:formatItem: function(data, i, total, value, searchTerm, totalResults)So now whenever a new search is preformed, I get back the number ofsearch result from the database.

2) Determine if a result set returned was empty I wanted to update a <div> with a message like "no records found" whenever the query yielded no results. Again, after searching the jQuery documentation, I couldn't find any property or method that would indicate this so I added it to the code. In the request function after the line var data = cache.load(term); I added the following:

if (!data) {
options.isEmpty(0);
} else {

Create A Small DHTML Code That Created A Unordered List Of Input Forms Dependent On The Number Selected From The Select Dropdown Menu

Oct 21, 2011

I wanted to create a small DHTML code that created a unordered list of input forms dependent on the number selected from the select dropdown menu. Problem is that it doesn't seem to want to generate the list. I think the variables are within the scope of the function too, and I didn't get an errors from the javascript console when using firebug. The script itself runs, I tested it when I used the old standby alert(); to see if the script was active. Here's the code:

Public Static Method Accessing Private Method

Aug 3, 2006

I'm trying to do something, but I don't know if it's possible.
Basically, I want to have a public static class method that could
access a private object's method. I would like to be able to do :

Class.method(InstanceOfClass);

The method would then access a private function from Class by doing
something like

function method(param) {
param.privateMethodOfClass();
}

I've done a lot research and experimentations but just can't come up
with a solution... I don't even know if what I'm trying to do is
possible.

Why Is The Callwhy Is The Slice Method Only A Method Of An Array Instance?

Jan 31, 2011

Why is the callwhy is the slice method only a method of an Array instance? The reason why I ask is because if you want to use it for the arguments property of function object, or a string, or an object, or a number instance, you are forced to use Array .prototype slice.call(). And by doing that, you can pass in any type of object instance (Array, Number, String, Object) into it. So why not just default it as a method of all object instances built into the language?In other words, instead of doing this:

function Core(){
var obj = {a : 'a', b : 'b'};
var num = 1;[code]....

//right now none of the above would work but it's more convenient than using the call alternative.

}
Core('dom','event','ajax');

Why did the designers of the javascript scripting language make this decision?
