I was wondering if the following would be a valid JavaScript
assignment vor a variable and if anybody knows this to work in IE6 or
lower?
var someVar = (typeof(someVar) === Object) ? this : getVar();
function getVar(){
alert('getVar() called');
return(true);
}
alert(someVar);
alert(someVar);
It seems to be working in FF 2 an Safari 3.
How is it possible to take the value of a variable (in this case,
MODE_CREATE, MODE_UPDATE, etc) and use that as an object property name?
In the following example I want 'oIcon' object to have the properties:
mode1, mode2, and mode3.
This seems simple but I can't quite figure it out...
Any ideas anyone?
var MODE_CREATE = "mode1";
var MODE_UPDATE = "mode2";
var MODE_DELETE = "mode3";
var oIcon = {
MODE_CREATE: "create.gif"
, MODE_UPDATE: "update.gif"
, MODE_DELETE: "delete.gif"
};
var oTitle = {
MODE_CREATE: "Create a new item..."
, MODE_UPDATE: "Update this item..."
, MODE_DELETE: "Delete this item..."
};
Is that possible I can assign an window object variable to an already opened
window? With window.open(), we can get a window object from opened window.
If a window has already opened, is there any way I can attach that window
with an object variable in javascript? Because I want to communicate with
that window.
Can assign a new function to a built-in object in Firefox:
But IE and Opera don't have a MouseEvent or HTMLElement that can be set up in the same way. Can you do this in IE or Opera, or just Firefox, and maybe Webkit?
I am using jQuery 1.4.2 and I am trying to carry over the global variable totaltabs into my JSON callback function. The code seems to work properly, however, in my loadJSON function after the callback function loads the data, my totaltabs variable will not increment.
Here is a peak at my code.
totalItems is loaded from another function, not relevant to my example.
Code JavaScript:
var totaltabs = 0;
$(document).ready(function(){
resize();

I'm writing a function that substantially load a given image making a fadeout/faidin waiting 'till the complete load. The function is named "loadImage" and I would like use it in the following way:
$('#image img').fadeOut().loadImage(src).attr("src",src).fadeIn();
In order to make the image disappear, load... change the attribute "src" of the image and then re-appear. The code for the function is:
(function($) {
$.fn.loadImage = function(src) {
var img = new Image();
$(img).attr('src', src).load(function() {
return this;
});
}})(jQuery);
But when I run it I get the following error:
$("#image img").fadeOut().loadImage(src) is undefined
I think that the function don't return a "valid" object to make it chainable, isn't it?
I was wondering if it were possible to assign a PHP variable's value to that of a JS variable. What I mean is having a var in JS, and then making a PHP variable equal to the JS one.
Like this code...
Now of course, this file will be .php, and will be called as such when including it to a page (<script type="text/javascript" src="username.php").
The above code doesn't work... But I want to know if it can be done in such a manner. I just want a PHP variable to be equal to a variable in JS.
I have a number of input boxes used to display totals based on
selected items for each row in a table. There are more than a few
rows that are identical, except for the form field name. I have added
a sample of that below (there would be many more rows).
I'm wondering if there is a way to dynamically generate the variable
names (ie: T1val, T2val, etc.) in my function 'calc', based on the
argument 'regnum' that I pass it. The problem right now, is that I
have to repeat lines 9 to 15 for every row that I add, using the
specific variable names for each. If there was some way to
dynamically create and assign them using the value of 'regnum'
(similar to using 'elements'), that would be great.
I guess one way might be to create hidden fields for each of those
variables, and I could then use the 'elements' syntax to assign
values, but wondered if there is a simpler way. Code:
If I assign an array to another variable, any changes to the array change both variables. Is it a pointer instead of a copy? Try this:
<script type="text/javascript">
Arr=['a','b','c'];
Arr2=Arr;
[code]....
Variables don't do this but it's happening for arrays in IE and FireFox, maybe all others.
Basically what I am doing is reading some values from a javascript that reads from an XML file. What I am trying to accomplish is a way to assign a variable that was declared within the "<% .. String strValue="" .... %>" section of my JSP page with a value returned from the script. Here is my code:
<HTML>
<BODY>
<%
String strValue = "NONE";
%>
......
<SCRIPT type="text/javascript">
xmlDoc=loadXMLDoc("customers.xml");
var x=xmlDoc.getElementsByTagName('name');
document.write(x[2].childNodes[0].nodeValue);
</SCRIPT>
</BODY>
</HTML>
As you can see in the above code the output of the script will be the 3rd node(starting from 0 to 2). I would like to assign the output of "x[2].childNodes[0].nodeValue" to the variable that was declared in the beginning "strValue".
I have tried different combinations but since the variable needs to be encapsulated with the "<% %>" notation because of JSP, I am stumped.
I have a variable in a js slideshow as follows :

I have a form set up in which the end-user enters in the 'alexr2012' (form variable = sname) How do I change out the alexr2012 to sname so that the Data value is not hard coded ? that is - the data value is determine by the end-user entry ?
I have several lines of code in different functions where I need to refer to elements in document.form.max, so I figured I would define it as a global variable called tb1 to shorten the writing. The result however is the page senses an error as soon as it gets to tb1.value, of which I can't figure out why since things work when I change tb1 into a local variable. I was under the impression that global = full scope, so I'm not sure what's wrong here.[code]...
View 12 Replies View RelatedI have a window with a form that is accessed directly. I would like to pop open another window from it and make the new window the parent/opener. I've tried the following but I keep getting 'opener is null' after trying to access the new parent's Javascript methods.
Code:
childWindow = window.open(someUrl);
window.opener = childWindow;
...
opener.someMethodInNewParent();
Am I going about it the correct way? Or is it not even possible to create a window and assign it as an opener to an existing window?
I was wondering if anyone knew if/how to assign an event to
a global variable?
I tried to do it and IE 7 came back with an error saying "Member not
found"
My code looked similar to the following:
var globalEvevnt;
function showPopup(event){
globalEvent = event;
alert(globalEvent.type);
setTimeout(function(){unhideDiv()}, 2000 );
}
function unhideDiv(){
alert(globalEvent.type); //Member not found error found on this
line
}
I was wondering if I had declared the globalEvent = new Object();
would that make any difference? I thought everything in JS was an
object so the event could be stored to one as well?
