I have the following code which will split the given input based on the comma(,) and will store each value in separate address of the same array.[code]...
How can we remove the empty values while displaying the output or how we can remove the spaces from array+
Is there a built in method to remove empty array elements?
View 2 Replies View RelatedI am not able to calculate the offsetwidth of the element which contains extra space in between the characters.for ex. if the element contains "A A" as a innerHTML value - if we calculate offsetwidth as 29 and also if the element contains "A A" value again I am getting the same offsetwidth as 29.While calculating the offsetwidth it is not calculating the empty space.May I know how to calculate the offsetwidth with the empty space because I need to insert the ellipsis (...) if it exceeds original width?
Code snipet
function fitStringToWidth(title,width,className) {
var span = document.createElement("span");
span.className="titleBar-Title-1";

I have a div ( id="rightheader") and inside there is a table. The following code replace all content of the table with empty space and then remove the table header.

but that just doesn't produce anything.
I have to create the 15 puzzle game and im having a difficult time getting started. i need to create a table (4x4) that has one empty space. All the other spaces must have a random generated value between 1 and 15. All i got so far is a onclick image swapping function.

View 6 Replies View RelatedI want to use JavaScript when a button is clicked to show and hide a
SPAN or DIV. This works in both IE and Netscape, but what I'd like to
happen is for there to be no white space where the hidden div is.
I start with two visible divs and in between them are two more hidden
ones...in Firefox this works fine--the two visible ones are right next
to each other, the button fires the script and the other div shows up
in the middle. Another button hides the div and the original two move
back together without space between them.
However on IE the two visible divs are separated by the amount of
whitespace that would be needed if the two hidden divs were actually
visible. They show and hide correctly, but the whitespace remains.
How can I fix this? Code:
I wrote a JavaScript that removes the white space from javascript source code in order to speed up download times.
For instance:
When I do my pop-up it has a blank white space above and to the left of the image. How do I remove this?

View 3 Replies View Relatedi have a special java code for input strings like:
Code:
<script type="text/javascript">
String.prototype.toCapitalCase = function() {
var re = /s/;
var words = this.split(re);
[Code]....
But i dont know how to make it work in <input> and this is also without spaces check ..
I 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.
How do i declare an empty array?
I need to iterate through a group of arrays and search for a user-chosen word every time.
The problem is i can't declare how many array elements will be needed, such as: new array = (12), because some words inside my arrays, occur more than others.
So i need to decalare an empty array with x number of possible values.
im 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...
What I want to do is declare an empty array. so i do it like this:
var changedValues = {};
Now i m populating this array dynamically with values, something like this
changedValues[elemName] = elemValue;
This also works fine. BUT, when i do a alert(changedValues.length)....
it gives "UNDEFINED" even though the array is not empty. Saw it through firebug .. Can anyone tell me wht is happening here?
What 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"?
I'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>
anotherVar 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.

I 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
Array(

When i click once on a button, i create one picture on the fly. And so on. It works ok. Then, using livequery, when i click on one of the all created pictures, i would like to see it removed. But it appears that only the first pic is removed (since all have the same name). What is my mistake ?

I have created an array that holds three textmessages, how can I
remove the created textNode and feed the next message in line? Is
there also an issue with cleaning any whitespace too?
A code snippet:
----------------------
var altTextBanners = new Array(
"myText1",
"myText2",
"myText3");
altTextBanners.currentIndex = -1;
function initRotate() {
if (!document.getElementById) return;
altTextBanners.currentIndex++;
var text = document.createTextNode(altTextBanners[altTextBanners.currentIndex]);
var message = document.getElementById("message");
message.appendChild(text);
// how to remove the created TextNode and get the next one in the array
// ... ??
}
HTML
<span id="message"></span>
I wonder if there any better method to check if the element in array B exists in array A, then remove it from array A.
Code:
var arrA = ['a','b','c','d','e']
var arrB = ['c'];
I copied and modified this code from somewhere I got it online, but not sure if I understand it as it has two for-loops in it...
Code:
for(var i=0;i<arrA.length;i++) {
for(var j=0;j<arrB.length;j++) {
if(arrB[j] == arrA[i]) {
var index = arrA.indexOf(arrA[i]);
}}}
code to remove element from array A,
Code:
if(index >= 0){
arrA.splice(index,1);
alert(arrA.join(" "));
}
After sorting an array, is this the best way to Remove duplicate array elements?
HTML Code:
i have a var ids = [] that returns some id's. for example
<li id="11"></li>
<li id="12"></li>
the variable ids will be return 11,12. what i want to do is to find those <li>'s with those id's and remove them.
I am trying to accomplish a fairly basic task with javascript > my lack of Js knowledge has meant i have hit something of a roadblock.I need the a function to take an array from a form, remove the parsed variable from it and repost the form with the new array.This is what I have so far...
<script language="javascript">
function remove(SID) {
var speakers = document.form_name.elements["SID[]"];

I'm trying to figure out how I replaces/removes parts of text in string in realtime using jQuery. This is what I got now:
PHP Code:
$str = 'This is a <b>test</b>. Its not going well!';
echo '<div class="element">';
echo '<span>'.$str.'</span>';
echo '</div>';
echo '<p>Remove</p>';
Code JavaScript:
$('p').click(function() {
$('.element span').each(function() {
var test = array('<b>','</b>','well');
//var test = 'not';
console.log($(this).text());
var text = $(this).text().replace(test, '');
$(this).text(text);
});
});
The problem: As above nothing happens. If I use the var test = 'not'; instead of the array part it works except it also removes the <b> tags? How do I get the array part to work and why is it removing htmltags when executed?
