var index = new Array();
index[] = 3;
index[] = 5

Why Is The Callwhy Is The Slice Method Only A Method Of An Array Instance?
Jan 31, 2011Why 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?

Need To Remove Empty Square Symbol From Text
Apr 19, 2010I have been looking for days for a way to do this but have made no progress.
The text looks fine in php but when displayed by javascript, some of the spaces are shown as an empty square symbol.
I have tried the following to change any unusual character to a space, but it doesn't help. code...
I believe that the character is created by a javascript-based editor when either the delete or backspace key is used to make an edit.
I have this strange symbol in many articles so I need a way to deal with this (the articles display fine when displayed by a php CMS).
I'm using javascript to show a preview of the article as a link tooltip.

JQuery :: Form Validation And No Empty Values With JS

Javascript Array Is Not Empty On Creation
Jul 23, 2005im currently working on a web app which uses heavy javascript. in one
of the functions, a simple array is created using "var admin_types =
new Array();". This array is not empty, it has a length of 0 but
contains one element with the name "clone" and the value
function () { var copy = {}; for (var i in this) { var value = this[i];
try { if (value != null && typeof (value) == "object" && value !=
window && !value.nodeType) { value.clone = Object.clone; copy[i] =
value.clone(); } else { copy[i] = value; } } catch (e) { copy[i] =
value; } } return copy; }
why does this element get created?? The weird thing is that i use a lot
of arrays and this is the only one that has that element.
i tried this in firefox 1.0, ie 5.5 and mozilla 1.7.1 and the element
is in the array for all of them...

JQuery :: Empty Doesn't Check Values After Loading
May 7, 2009I'm trying to select my textarea only if it is not empty. I have used :empty for this purpose. This works find when you load the page, however if you start typing in it still considers the value as it was when the page loads.
Example. If my textarea is empty when I load the page, it will consider it empty. If I starting typing in, and check if it is empty it still say it is empty.
The same vice versa. If my textarea has text when the page loads, then i clear that data, it still consider it filled not empty.
So how to make the check of :empty in real time?

View 8 Replies View RelatedEmpty Array Element Variable Type?
Oct 22, 2009What type of variable is an empty array element? I thought it was undefined, but i noticed that they have different behavior than undefined does:
var r=Array(1);
var s=r.concat([0,"",null,undefined]);
alert (s.toSource()) //==="[, 0, "", null, (void 0)]"
typeof s[0] //==="undefined"
typeof s[4] //==="undefined"
As you can see, 0 and 4 both === undefined. Yet, they don't have the same toSource()...
Is this special type named anything specific? Or more importantly, can it be detected outside of an array as being distinct from undefined? I am thinking this would be the same type as ({}).nonProp ...
I guess the question is actually, "can you tell the difference between uninitialized and undefined"?
Error Handling - Display Array If Not Empty Into DIV
Sep 17, 2009I'm not an expert with javascript nor am I too familiar with the syntax. What I'm trying to do is store all errors into an array like so:
Code JavaScript:
var errors = new Array();
var example = '';
if (example == '') {
errors[] = 'This example field is empty';
}
What I'm trying to do at the end is display the array if its not empty into a DIV called errors (or something). I know how to do this in PHP but I'm trying to do first validation layer through javascript. So something like this:
Code JavaScript:
<div class="errors">
if (errors != '') {//If the array is not empty
for (keyvar in errors) {
document.write(array[keyvar]);//Display Errors
}
}
</div>
Default Operator ( || ) Doesn't Work With Empty Array?
Aug 13, 2010anotherVar should be -1 if there are no matches, but it doesn't seem to work var string = "abadafa"; var matches = string.match(/a/gi); //doesn't work with /z/ for example
var anotherVar = matches.length || -1; The default operator should return the second value if the first is null or false, and according to try { alert(matches.length);
}
catch (e){
alert(e); //alerts null
} it's null.
fyi: http://helephant.com/2008/12/javascript-null-or-default-operator/
JQuery :: Hiding Subset Of Form Fields (with Empty Values) Using Focusout Handler?
Feb 4, 2010I have a contact info form with about 16 fields. I need to hide a subset of fields for address when the end user either (1) tabs out of the subset group, (2) clicks anywhere outside the subset field group.
I do not want to hide the fields when the end-user is tabbing within the subset of address fields, yet the focusout handler is triggered when it shouldn't be.

Comparing Array Values To Select Unique Array Elements?
Apr 10, 2010This one is throwing me off! Either I am making a stupid mistake or I'm doing it totally wrong I have an array, and I am trying to select unique values from it and assign it to another array. Here is the code:
Code:
var flag;
for (i=0;i<=pdfs.length-1;i++)
{
flag = 1;
for (j=0;j<=pdfs2.length-1;j++)
[Code]...
The problem is that the if (pdfs2[j] == pdfs[i]) statement ends up never being true. There are URL's to pdf files in the array. On the other side, if there is a much easier way to select unique values from an array, please feel free to point it out.
Jquery :: JSON Submit - Decode Empty Array At Server Side
Feb 22, 2011I am doing a password reset form using Jquery and PHP. If I try to submit an email id it should sent and email and report back the response text as success so that the user knows email has been sent. But I am stuck with JSON submit as I have an empty array to decode at the serverside. I am using minified version of json2.js from the official json.org website
Here is the code.
Code JavaScript:
var formdata = $("#log-box").serializeArray();
formdata = JSON.stringify(formdata);
var notifymsg;
alert(formdata);
$.ajax({
type: "POST",
url: "forgot-pass.php",
contentType: 'application/json',
data: formdata,
success: function(responsedata){
var some = responsedata.split("&");
$.each(some, function(index,value){
//alert("index="+index+"value="+value);
});
},
error: function(o, s, e){
alert("Form not posted
"+e);
}});
formdata alerted gives:
[{"name":"email","value":"ravi.k@gmail.com"},{"name":"acctype","value":"loginaccount"}]
PHP forgot-pass.php
Code PHP:
print_r($_POST);
Gives

Removing Values From Querystring Before Being Sent Through Form (get Method)?
Jul 23, 2005Just wondeing if there is a way to keep from having a certain
parameter sent when posting a form to another page (method=get)...
So as an example a page will post something like this from a form
using "get":
http://mypage?firstElement=1&secondElement=2
How can you completely remove "secondElement=2" from the
querystring... Before moving on to the posted page?
I know you can actually remove the element using removeChild in
javascript, and therefore it won't show up in the querystring of the
page posted to:
ochild.parentNode.removeChild(ochild);
But I was wondering if there was a way of doing it? A person can see
an inputbox for example disappear for a split second before the page
is posted... Is there a way of accessing the querystring itself in
javascript? Or some other way then removing the element?
Getting Values From Form Submitted With Post Method
Mar 2, 2006I am having trouble finding a code example that uses javascript to get values from a form submitted on a previous page using the "POST" method. I've found some examples on how to parse the query string, but unfrotunately my form on the previous page has WAY too many charcters being submitted to be able to use the "GET" method (there is some upper limit here, I think it may be 255 or some number similar).
By the way this ONLY needs to work in IE, but it is better if it works in all browsers.
