Inserting A Variable Into Document.formname.radionname[elementnumber].value?
May 13, 2010
I've been looking around the web and forums for the past few days now. Javascript is not my forte but I am beginning to understand more of it. My issue is perhaps in the method that I have tried to concatenate a variable to my radio buttons.
The scenario:I have about 10 groups of radio buttons , each with 4 options.
radioname1[0]
radioname1[1]
radioname1[2]
radioname1[3]
[code].....
but what I need to know is how to assign a variable to the radioname, so that I can iterate through each radionameVARIABLEHERE[i].value ?
I have been looking and trying to for days. All I really need to know is how to get a variable into the radiobutton name. I know how to use a for loop to get this to iterate through it all but its just the syntax that isn't playing nice.

I thought I once saw somewhere that a global variable, "xyz" for example, could be declared and used so that instead of using "document.formname.elementname.value" one could use "xyz.elementname.value" or use "xyz" in place of "document.formname" anytime a reference to a form element was made.
Is this actually true or not? I'm going crazy trying to recall something that might not even exist!

I am developing in firefox 1.0+, but will be working in an msie 6.0+
produciton environment ( not my choice, but when is it ever? ).
the desired output is that when the end-user selects two radio buttons,
one from each 'group', the form / page will open an alert window
displaying the values of the radio buttons selected without having the
end-user left-click on a submit button.
i cannot figure out why I'm getting the "document.[formName] has no
properties" error mesasage in the javascript console....

I'm not so good at Javascript, but I tried to write some code to obtain some form values and write those to a query string to use in AJAX.It seems to be working partially, but I don't understand what is going wrong. What happens is that in the for loop the 'document .form_name.form_field_names_array[i].value' part doesn't seem to return a value. It is worse even: the script completely stops executing at that part. When I remove that part from the line in the for loop, it doesn't stop executing, so I guess that's where the problem is?
function doAjaxForm(url, target_element_id, img_url, form_name, form_field_names)
{
// Create the GET query string from the form_fields[code]...
// Rest of the code (the AJAX) is working.

I can successfully force submission of a <form> using "document.formname.submit()". But, the submission doesn't appear to occur when used with Netscape. Anybody know why this is happening, and what I can do to get around this?

So im working on a case where I need to make a random ad pop up every time I refresh that web page. I've got all the steps down except to where I need to insert a command to write the text to the document.
*Insert a command to write the following text to the Web document:
<a href="URL">
<img src="adn.jpg" alt="description" />
</a>
where URL is the value of the rLink variable, n is the value of the rNumber variable, and description is the value of the rAD variable.
what I have so far (all steps completed) is
<script type="text/javascript">
var rNumber= randInt(5);// generate a random integer from 1 to 5.
var rAd= adDescription(rNumber);// description of the random ad.
[code]....

I'm trying to insert a javascript variable into a hidden input form
field. Here's what it looks like:
<form name="loginForm"
action="scripts/wgate/ziac_login/!?~language=EN">
<input type="hidden" name="pss" value="`G_NEW_PASSWORD.value`">
<input type="hidden" name="usr" value="">
<input type="submit" value="Please Click Here to Continue">
</form>
and then later down the page I try to reassign "usr" like this:
<script>
var allcookies = document.cookie;
var position = allcookies.indexOf("user=");
var start = position + 5;
var end = allcookies.indexOf(";", start);
if (end == -1) end = allcookies.length;
var valueofuser = allcookies.substring(start, end);
valueofuser = unescape (valueofuser);
document.write(valueofuser);
document.loginForm.usr.value = valueofuser;
</script>
I can see it is printing out document.write(valueofuser) correctly, so
I know it is grabbing the user name. But it doesn't seem to want to
insert it into the form on the next line. Any suggestions?

I am having a problem where I want to change a particular variable based on what parameters I send to a js function.
In the code below, dnum is a number 1-6, and I want the global variable d1keep (or d2keep, d3keep etc.) to equal the dvalue.
function KeepDie(dnum, dvalue) {
d+dnum+keep=dvalue;
[code]...
I've tried using single quotes, double quotes, brackets, curly brackets, parentheses, and other punctuation in many locations all over that line of code, but I cannot get it to work.

i'm not really sure how to explain this, since I know nothing about javascript, so i'll try and illustrate by the use of php (hope it makes sence)
I have a set of different links, like:
<a href="link.com?page=text1">text 1</a>
<a href="link.com?page=text2">text 2</a>
<a href="link.com?page=text3">text 3</a>
etc, where page is dynamic and can be anything I chose..
Another place in the same document, I echo out what the page variable is, like:
echo "$page";
so when clicking "text 1" the echo will output what i've defined the page to be, in this case "text1" ..
So I want to be able to click the links and change the output of the echo all depending on what i've defined in the link - without refreshing the page!
Is there any easy way to do this?

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

I have a function that takes parameters of what the form name and the form object name is and then modifies the form accordingly. Now I can make it work fine if i make a separate function for each form object, but that seems very cumbersome. This is what I have
document.formName.formCat.selectedIndex;
i want formName and formCat to be variables so I can specify in the parameters which part of the form to deal with, but i get an erorr. Is this possible?

I've got a piece of code where, for all the world, it looks like this fails in IE 6:
hometab = document.getElementById('hometab');
but this succeeds:
hometabemt = document.getElementById('hometab');
Has anyone ever seen anything like this before, or am I dreaming?

I've got a number of divs with the prefix menu and the suffix where is say 1-10. My code is below. It assigns the click function fine to each, but assigns them all the function based on the last value of the for loop. (It calls the current value, while I want the value from when the code was originally executed to set up the click function). Scratching my head on how to accomplish this.$(function(){

I have a little JS app that is a glorified calculator which I posted the code for below. My code uses the document object to replace the html in the "content" <div> and works great.However, I want to add an inline style in order to change the background of the input (readonly field with an id of "coutput") based on either of the global variables named "MJPD" or "IJPD", (depending on the switch case selected in the user prompt at the beginning of the script.)Simplified....if the value of MJPD is less than 4.6, I want the "coutput" field's background to be red, else be green.The same goes for IJPD, except the threshold for red will be <3.83.Code and what I have tried is below.
<script language="JavaScript">
var MJPD = 1;
var IJPD = 1;

Let me preface this with the usual disclaimer: I am new to this and have only been programming with Javascript, PHP for about 2 weeks now and have been lucky enough to have resolved the issues I have encountered. This one however is puzzling to me.
I have a HTML form created that collects member information. It calls, on submit, a confirmation page that lists all the data fields entered. This all works great. However, when I then post the variables from the first html form page from my second confirmation html page to my PHP script, using document.write with input type=hidden and inserting the address variable into the value field, the Javascript only passes this variable up to the first space. It is the only variable I pass that has a space in it.
I have verified that the variable does indeed contain the whole address and I have also verified when I execute the following: document.write ('<input type="hidden" name="address1" value='+address_1+'>');
the address_1 parameter passed to the php script only passes the string up to the first space.
I even tried to put fixed text in there instead of a variable (e.g.)
document.write ('<input type="hidden" name="address1" value="555 Drury Lane" >');
and it still only passes the string up to the first space (555).
I show the variable address_1 on my confirmation page and it shows the entire string.
I checked what was being passed and it seems that the Javascript is the culprit (or more likely the Javascript creator - me)
All my other variables (which don't have spaces) pass to the php script with no problems.

First script, 'xxx.js' returns value 'document.write('integer');
So in HTML:
<script language='javascript' src='xxx.js'></script>
will write ie. 123 on my page in browser.
Can I get this integer or text 'document.write('integer')' to variable in
another script? So it would be something like this:
<script landuage='javascript>
a=<script ... src='xxx.js'></script>;
a*=20;
document.write(a);
</script> ...

I'm pretty new to JavaScript and am having a problem. I thought what I am doing should work but it isn't.
Basically I have a form that people can put a quantity into. e.g. A, B, C.
I have a JavaScript function called comput that assigns values e.g. A = 5, B = 7, C = 9. Here is the start of the script:
<script language="JavaScript"><!--
function compute(form){
var A = form.A.value * 5;
var B = form.B.value * 7;
var C = form.C.value * 9;
I then declare a variable to add them up:
var ans = A+B+C;
return;
}
</script>
This part of the script works fine. Now I want to write the ans variable. So I use:
<script>
<!--
document.write ("Your total is "+ans+"")
// --></script>
But it isn't working. Any ideas?

Normally an SVG document is loaded/parsed/interpreted inside an HTML
document using an 'object' (or 'embed') element, although there are
supposedly other ways too. The problem is, the SVG document must be
static this way.
I want to use the DOM interface to build SVG dynamically inside an HTML
document. I am guessing I can build it inside HTML within an 'object' (or
maybe 'iframe'?) element.
My intentions/goals:
In Javascript, I construct an object 'embedSVG' which has properties and
methods for creating valid SVG elements and setting their attributes and
attribute values.
During construction, the SVG document is created with its root element.
During debugging in FF 2.0 (I'll work on an MSIE-compatible format later),
I am using the Mozilla DOM Inspector and comparing nodes when the
'object' element is loading a valid external SVG document, and when I am
appending the child representing the SVG document created by the DOM
functions.
However the child node (#document) does not specify 'svg' as the root
element, but instead 'HTML'. Something is not working.
Here is the relevant code in 'ScriptTest.html' which is the HTML in which
the SVG is supposed to be embedded. Below it is the relevant code for
'svglib.js' which is supposed to contain code for building the SVG
dynamically.
What this code is supposed to do is load the HTML page and execute the
anonymous script, and draw a navy blue-bordered yellow rectangle on a
blank page. This is similar to the example in the SVG 1.1 W3C
Recommendation on page 202 of the 719-page PDF.
I am getting an exception when embedSVG object placeInHTML() method is
called: NS_ERROR_DOM_HIERARCHY_REQUEST_ERR. I find in DOM Inspector in
spite of or after the exception that a document is placed as a child of
the object element, but it is HTML, with a default 'head', 'title',
'body' elements placed.
Where am I blowing it?
