I am pretty rusty with javascript and I am trying to make a webpage
that will basically act as a wrapper from one webpage to another. What
I mean by this is that I will hit this page like:
webpage.htm?Param1=... and I will take the passed params and post them
to another page. I have the post part working, but I was just
wondering how I can use just Javascript and read those values passed to
this webpage. Is this even possible?
html code:
view plaincopy to clipboardprint?
1. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
2. <html xmlns="http://www.w3.org/1999/xhtml">

I want - when the page load in result div will apper "Hello bla bla". It works for me if I dont use parameter(aka data: "{ }" and HelloToYou dont accept parameters)
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? 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?
I have two methods and I would like to call somename1 method from within somename2 method. I have tried several ways to do so however I keep getting "TypeError" or "RefernceError" I have tried several ways to reference but I am still unable. What am I doing wrong. I would think this would be easy to do.

Can someone give me some pointers on how I can read one or more
arguements from a url, using js?
Why? I'm working on a LAMP based project and when a user successfully
registers, the header redirects to the login screen - I'd like to check
for the value of register, if read from:
http://www.mydomain.com/index.html?register=success
A pointer/hint as opposed to a solution should be sufficient because I'm
doing pretty well learning javascript.
I found this little script for extracting parameters from a url but wondered
what the shortest and most efficient way to do it would be, like the
following or via regexp?
function getParameter(paramName) {
var currentUrl = window.location.search
var strBegin = currentUrl.indexOf(paramName) + (paramName.length+1)
var strEnd = currentUrl.indexOf("&",strBegin)
if (strEnd==-1)
strEnd = currentUrl.length
return currentUrl.substring(strBegin,strEnd)
}
Any shorter way?
I have an onclick function that pops a new window (nothing fancy) the problem is that whenever I want to return to the page where I popped the new window from I find that it is reloaded and has taken me to the fist line of the page. What parameter (or anything else for that matter) can I add in order to pop up a new window and still be in the same place when I return to the previous page?

I haven't used Javascript in agggeeesss and I can barely remember anything anymore - PHP <3
In the javaScript function below, is there anything I can add to the window.open so that the parameters passed in the URL do NOT show in the window that is opened? It is okay if the script path shows, I just need to hide the parameters. If that is not possible, can I have it show no URL show at all?
function OpenTest2(ID,course,test)
{
var agree=confirm("Are you sure you want to Launch this test?");
if (agree){

Is there a way to send parameters to the function being added to an event with addEventListener. I.E. say you have this function
Code:
function someFcn(i){
alert(i);
}
and I add it to an object.
Code:
someElement.addEventListener('focus', someFcn, false);
Is there a way to send a parameter to someFcn.
For Example I have tried this but it failed
Code:
var someString = 'Hello World'
someElement.addEventListener('focus', someFcn(someString), false);
I have a url with parameters like the following:

What is the easiest way to parse the query string out of the url? When I use self.location I get everything.
Ok I am pretty sure Javascript is the only way to do this I need to pass more than one parameter from a form to a url For example:
I need this output
Code:
http://mywebsite.com/index.php?price_min=10&price_max=20&sort=featured

http://mywebsite.com/index.php?price=10
Code:
<form method="get" action="http://mywebsite.com/index.php"

I have a query string which contains various elements...
&Var1=10.00
&Var2=5.00
etc.,
I'd like to reference these values within my html code (multiple times). I've tried embedding <script> javascript tags into the html, but this doesn't work. I.e. <script>var MyVar1= getElementById('Var1').value;document.write MyVar1;</script> I can obviously refer to the element once by putting within an input form element, but I want to refer to the variable mutiple times.
I have a JavaScript function that receives an Array with words. This
Array can be gotten from a query to a DB using JSP.
The JavaScript function is executed when onFocus event occurs:
<input type='text' onFocus='myFunction(this.event, myArray);' />
myArray is declared as:
<script>
var myArray = new Array('j'habite', 'tu habites', 'il habite');
</script>
I want to tell javascript:
var myArray = myJSPArray;
Where myJSPArray is declared some where in the JSP document.
I have an applet and want to change it's parameters with multiple links in
my page.
this is my code:

<param id="moneyID" name="money" value="100">

<param id="countryID" name="country" value="UK">
</applet>
How to create a function that will be called from some links and change the
values according to the user's values (from a textbox or anything else).
This should be simple, but can I change parameters like the url coming
in:
www.testpage.com?test1=a
<script>
document.setParam("test1", "b");
</script>
something like that? I want the parameter to change based on the code..
I would like to reference the "name=value" parameters sent to my page
(submit'ted from a previous page with a <form>.) in my javascript.

I don't know where these parameters are if my second page is called with a
"post"...
I keep getting a runtime error stating that this
document.adddealer.dealertoadd.value = dealer; is null or not an
object. I've rewritten the Function everyway I could think of, and
couldn't find any thread examples of my problem.
Here is my Function;
<Script language="JavaScript">
<!--//hide
function AddDealer(dealer) {
document.adddealer.dealertoadd.value = dealer;
document.adddealer.submit();
}
//-->
</script>
This calls the Function;
<input type="button" value="Make This My Dealer"
name="button">
When the code breaks and I bring up Microsoft Debugger it shows a
value in the parameter.
