Passing Function Parameter Into GetElementByID?
Oct 3, 2010
I am trying to pass a variable into document.getElementById and it is returning a null value. I am hoping someone can identify my error and point it out. The frustrating thing is, I got it to work and then changed the code and screwed it up again...ugh. Anyways, here is the HTML side of it (an onclick event in a button, calling a function with these arguments):
Code:
<input type="button"
id="AddHeader"
name="Add Header"
value="Add Header"
[Code]....
FireBug shows the problem is with the first line of the function - it's assigning myDiv null instead of what I want it to assign it (div#myDiv1 I think).

I have develop an ActiveX with Visual C++ 6
And I will call functions on this ActiveX from a javascript.
I know how to instantiate the activex object (with the balise <object>).
But how can I do to call a function of my ActiveX and pass to this function
some parameter by reference.
Here is what I have :
the function in the ActiveX :
void test(long *t, long FAR* nb)
{
t = 3 ;
}
And here is what I try to call this function in javascript:
var myT = 0;
my_control.test(myT); // here is the problem that
alert("T : " + myT);
But I receive the value 0
So how can I do to pass parameter by reference to a function of an ActiveX?
Is there anything to change in my function in the ActiveX?

I had a script that was acting unexpectedly because of a function parameter. I was trying to pass a jquery object through a function to attach some events. I was wondering if someone could tell me why this
didn't fly:

why this code works in FF, but fails in MSIE? In particular the content / display of the <select> options.
What is different in the executions of the same script on different browsers?
What can I do or change to make it work in both browsers?
Code:
<html>
<head>
<title> Pass array by reference </title>
<script type="text/javascript">
[Code].....

How can I still use the parameter "openAccordionID" in the blue-highlighted part? I tried, but it failed.

my first attempt to post seems to either have been rejected or simply gone into the cyber void.
I currently have a link on a webpage as follows:
<a href="#" id="loadData"><img src="images/bookcase.png" alt="" width="114" height="167" border="0"></a>
which is picked up by
$("#loadData").click(function()
which then executes:
.load("subgenre.php" , function() etc
What I want to be able to do, however, is pass a parameter to the php script, along the lines of:
.load("subgenre.php?param=" + passedParam , function() etc

I'm a perplexed nube, and I can't understand how document.getElementById evaluates to true when no parameter is passed to getElementById. This code alerts 'foo' if (document.getElementById) {alert('foo')} else {alert('bar')}
Just to double check, this code alerts 'bar'
if (!document.getElementById) {alert('foo')} else {alert('bar')}

I have a javascript function that is called in an OnClick event for a
button.
I am attempting to get the function to open a web page in a new window
in response to a button click.
I can get the page to open if I use the following syntax (hard code the
address)
var newwin =
indow.open("http://www.w3schools.com","","width=1200height=1000");
However, If I pass the url in as a parameter to the function (as below)
the value passed in is "Undefined" and obviously the page will not open
function openThePage(url)
{ url = "http://www." + url;
var newwin = window.open(url,"","width=1200height=1000");
}
<input
class="mybutton"
type="button"
name = "W3Schools"
value="w3schools.com"
onclick="openMyUrl(W3Schools.Value)">
Anyone any idea how I can do what I want - what I am doing wrong. I am
grey enough as it is and I don't want to start pulling my hair out.

I've been staring at this same problem for over a week now. I've worked around it as best as i can but i think it's time to ask someone else for input.
I'm trying to pass a value thru an ajax parameter.. that's all. it SHOULD be easy in theory.
What i want to do is create a jscript variable then pass that variable as the value for a parameter.
Php then converts that value to something it can use to finish the rest of my code.
As i said it's hindering my webpage progress and i would like to get it fixed soon.

I am trying to pass an element's id to an ajax function so that I can update different areas by passing different ids to the same function, but I am not quite sure how to get it passed to where I want it to go.
Code:
function calGet(date,month,year,id,action) {
xmlHttp=GetXmlHttpObject();
if(xmlHttp==null) {//ajax won't work, redirect to a calendar php page to display the event with php
[code]....
In the function calGet I passed a parameter 'id'. I want to get this parameter down into the getElementById area in the stateChanged function and I've tried, many many ways, but I cannot figure it out.

This is what i want to do: When the user clicks "Add a New Page", it adds a table with the id="pageX" and a delete button with the id="deleteX" where X = the next page number.
When they click deleteX it should make pageX table display:none and assign a value to deleteX.
I got it to do everything except for assigning deleteX with a new value. the code that makes the delete buttons not work is:

My WEB site opens an application window and then, from its original window it navigates to a status page.
Code:
var newWindow
function popUpApplication() {
newWindow = window.open(url, parameters...);
[Code]....
Now the problem with this solution is that if the window was closed by the user I will end up with a new pop up window, which I would like to avoid... Unless there is a way to check for window existence prior to attempting to create a new window.

I have a loop that iterates over an array of objects.
Then for each of these objects, a div element containing an img element is created and appended to the document.
Further each img element must have an onclick event that basically changes the backgroundColor of it's enclosing div, as well as make changes to the associated object in the array.
The loops basically looks like this:
Code:
Now everything is created fine and the events are bound to the images, however, the only things that change in any of the onclick events are the very last container and object passed. For some reason it seems that the references in all the previous loops are replaced with the newer ones.

I have a function that changes the innerHTML of a DIV element. I want to pass to that function as a parameter a reference to the DIV to be changed. In the example below it works the first time (executed with the body onLoad event). As the subsequent function declaraton is rewritten by the function itself, it can no longer reference the targeted DIV. I tried to pass a string teference and use eval(), but this time it fails the third time it is executed.
Code:
<html>
<head>
<title>Passing Parameters to a Function (with object prameter)</title>
<script type="text/javascript">

I have a search page im asp.net. the user enter the criterias in
textboxes and dropdownlists and on submit i want the results to be
displayed in a popup window.
so the easy way is to pass the criterias in a querystring to the new
window. but if it's possible i don't want to use query string.
in asp, i could use the folowing:
i open a temporary blank window, on load I take the values of the search
page using the window.opener and submit them to the server.
Unfortunately this can't be done in asp.net coz window.opener isn't
working.
so is there a way to do that ? or the only way is to pass the parameters
in a querystring ?
