I know that IE6's support for CSS is well... hmmm... lets just say not very good, however I was wondering if style declarations can be added at run time, via JS?
e.g.
Can I create a new rule?
i wonder how can i have both javascript writen inside body and css declaration
here's my page: i only see the output if i comment the css line: Code:
I have Declared same function and two diff javascript files and both files are included in HTML page and one more same function declared in HTML code too... So problem is that, which function will execute first, i mean function in either javascript or function in HTML Code?

function setupGrid( param ){......}
and
setupGrid = function( param ){......}
Are there any advantages to doing one over the other?
There is something that I don't understand well, I use array for
combining strings like
items = ['hello world', ', how are you', '?', 'the end'].join('');
in FF this works well but in IE I had to add something like this
var items = new Array();
items = ['hello world', ', how are you', '?', 'the end'].join('');
My question is why is there a need for var items = new Array(): and
why items = new Array(); doesn't work? I don't want the items to be a
global variable, since it was declare inside a function I want it to
be local only.
Below are some over simplified examples of code the create a single
instance of an object and I was hoping some one could give me the pros
and cons of each approach.
First declaration: In this case a single object is created using object
literal notation and both the get and __Private methods are availabile
for use and no closure is created.
ABC.Util.SomeObject =
{
get : function(val)
{
return this.__Private(val);
},
__Private : function(val)
{
return "testing";
}
}
Second declaration: In this case a single object is create and only the
get function is availabile for use and a closure is created.
ABC.Util.SomeObject = function()
{
var __Private : function(val)
{
return "testing";
}
return {
get : function(val)
{
return __Private(val);
}
};
}();
I have the following code which attaches a function to events in x number of comboboxes (x will probably always = 4, but I do not want to hard-code this). I wish to pass the value of i to the function being attached as well as the value of tempData. In other words, I want the parameters in function to be the value, not a reference variable.
In the current example, I am using the hard-coded variable ci. This I want to be replaced by a literal created when the event handler is attached (the value of the loop variable i). Also, notice that I get the filter value in the event handler (assigned to the variable ct). I would like to replace this code with the value of tempData which would also be determined when the evenet is attached (it is the same value in this case, but it keeps the onChange event from having to do this each time it runs).
var props = {
col_0: "select",
col_1: "select",

I've been looking all over for an explanation of this function declaration but cant find it. what it means to have a function with no name, just declared as this. When does it execute? How does it get called?
For reference, here's the function:
is it true that the doctype declaration must be on the very first line (there mustn't even be a blank line above it) in order for it to be "working correctly" ?
View 8 Replies View RelatedSay I have a code snippet like the one below:
var elm1 = document.getElementById('elm1');
var elm2 = document.getElementById('elm2');
function doStuff(e) {
// Some stuff is done here...
}
function addListeners(e) {
elm1.addEventListener('click', doStuff, false);
elm2.addEventListener('click', doStuff, false);
}
window.addEventListener('load', addListeners, false);
This code will generate an error, namely "elm1 has no properties". To many I guess this isn't very surprising, and my own take on this is that the addListeners function is run before the variables are declared. But what I fali to see is why? To me, a fair beginner with JS, everything is in its right place. What am I missing?
I would very much appretiate if someone could explain the order (when and where to declare the different parts) in which my code here should be ran. Is there something special to have in mind when using window.addEventListener('load', functionname, fasle);?
i did not undestand weather 'var' Keyword should be used or not when declaring variables. i already familier with php and there i will not use a 'var' for variable declaration. i like to program JS using similler PHP sysntax. so i code JS with out 'var' for varialb declarations and it works.
but can you please tell is it ok to declare variables with out the key word 'var'? if this is not good, then do all global and local variable declarations requir 'var'?
I have been having trouble with forms and functions. On my wife's site I have some forms and some of them have radio buttons. My current radio button checker is cumbersome and it is time for something more elegant (some of you will say if it isn't broke don't fix it )
The new code is below:
Code:
Basically I want to pass into the function radio button values 1 & 2 denoted by firstChoice and secondChoice (eventually I want to also pass in the form name but 1 step at a time).
The buttons can have the value (names?) of pattern, chalkboard or kit. It is for a shopping cart (Mal's E-commerce) and this is part of the JS validation. I am using onsubmit to call the function viz.
HTML Code:
Seems ok (to me at least) but when I try to get it to work it throws up an error of
Code:
It stops at that point but undoubtably chalkboard would throw up the same error if it continued.
How would I define the variables in my function? Are they strings, integers, who cares?
Where would I define them? Global or local?
Is the problem a matter of syntax e.g. if I put ' ' or " " around them would that suffice?
I have the javascript (which is pasted at the end of this request) on my website, but it will not work whenever I include the Document Declaration just above my <head>.
Is there something I can change in the code that will make it work?

View 2 Replies View RelatedI understand that there is no need to initialize a variable at the point of declaration. OTH, what is the default type of a [declared] variable? For example:
[Code]...
Take a look at this example:
Code:
function foo(var1, var2=NULL){
if(var2 != NULL){
//do something
}
[Code]....
and in this scenario, var2 would have a NULL value
My question is: Is it possible to declare a null parameter within a function declaration in javascript? (as in the example)
I know this is possible with PHP, but i am having problems with this in Javascript.
I want to add this html code as a var or a const, so then later I could do document.write(x);
Like:
But this do not work.
If you specify arguments when writing a function should you still declare the argument variable inside the function?
example:
Code:
or

Well, it turns out IE8 has yet another problem. My code has a global variable (to the object) inside an object declaration that cannot be accessed by a function (that is also global).
The code is like so:
Code:
function myobject(params){
//public
this.initialize = function(){...}
//private
some variables...
//problem variable
var mouse = new Object()
mouse.x = 0;
mouse.y = 0;
//code...
slidecontainer = document.createElement("div");
slidecontainer.onmousemove = function(event) {
if(boo.isIE) {
e = window.event;
mouse.x = e.x + document.body.scrollLeft;
mouse.y = e.y + document.body.scrollTop;
} else {
e = event;
mouse.x = e.clientX + document.body.scrollLeft;
mouse.y = e.clientY + document.body.scrollTop;}}
//this function is in an interval
function moveslides() {
/* this is where I have the problem
It seems that the function doesn't recognize that mouse.x, or mouse for that matter, exists. Mouse is global to the object, so why can't this function access it?
*/if(mouse.x) {
code...

I have a situation where I'm displaying some information in a table on
a web page. I've given the user the ability to make several different
"queries" and show different sub-sets of the data.
I would like to add a button to the page that would allow the user to
create an .XLS file that would contain the current contents of the
table. I realize that I could create it on the server and allow him to
download it but I'd rather let him create it right there on his
machine. Is it possible to have a script that can do such a thing?
I am trying to create/update a Php Session with Javascript to confirm
if users have Javascript enabled.
My first thought was to create a Javascript that writes a script tag
referencing a php page, which sets a $_SESSION variable.
javascript.js:
<script type="text/javascript">
<!--//
document.write('<s'+'cript type="text/javascript"
src="javascript.php"></s'+'cript>');
//-->
</script>
javascript.php:
<?php
session_start();
$_SESSION['javascript'] = 'enabled'
?>
I can see that both the javascript.js and javascipt.php files are
executing from the web logs, but when I try to query the
$_SESSION['javascript'] variable from another page $_SESSION is empty.
Is it possible to create/update a Php Session with Javascript?
Might it be done using URLEncoded URL, Javascript XMLHttpRequest, or
something of the like?

is there a way to create iframes using cookies and javascript? What i need to do is to have a way to create a cookie on page one, and use the info on page two to create the iframe.Users will see a list of "external links", once they click on a link, they will be redirected to a page that will generate a iframe of the chosen link.My guess is that if there is a way, it must need to use cookies to store the info (url) to get used by the script that will create the iframe on the page that will be used to show all iframes.
