Returning Value From Prompt() ?
Jul 20, 2005here's what we have in an html file.
<form .....
<input type=button name="comment" onclick=" prompt('enter comment','
' )" >
Is there anyway to get the value returned from the prompt in the statement
above, into the value of the statement below ?
<input type=hidden name="comment_text" value = ???? >
We would like the user to click the "comment" button, have another window
popup where they enter their comment, and then take the comment text and
append it to the value parameter of the hidden statement.

May 21, 2010I know this is probably a really simple this to do, but for the life of me I can't figure it out. I want to find out the value of a style for a certain element. So say in the CSS I said 'content' had a width of 100px, but I want to get that value with Javascript.
Here's my shot at it:
alert(document.getElementById('content').style.width);
I just get null.
IE7 Returning 'toJSON' Instead Of 'i' Value
Mar 3, 2009I'm not overly proficient at Javascript, but have fumbled my way through some tutorials to come up with the following code to create a tab mechanism.
It works perfectly in Firefox, Safari, Chrome and IE8. However, in IE6 and IE7 it fails to operate as of the 'for (var i in temp) {' line. It doesn't error out, it just doesn't perform any of the functions within the for.
Some things I've noted: * In Firefox if I alert(i) below the for, then it alerts the numerical value of i correctly through the for loop. * In IE7, however, alert(i) alerts the value 'toJSON' and nothing more. It never finds 'if (i <= maxlen) {' to be true as a result.
Any thoughts on what's going wrong here?
Code JavaScript:
function toggle_visibility(showid, hideids) {
$(showid).style.display = 'block';

View 1 Replies View RelatedGetElementById Not Returning Value - Undefined
Dec 10, 2010None of my getElementById (or other) references produce anything but "undefined." This occurs in the latest versions of Fx, IE, Chrome, and Safari, so it must be something I am doing but not not seeing here. I have boiled it down to the following without success, and wonder whether there is some add on interaction. Fx 3.6.12 has the problem with this code:
<code>
<html>
<head>
<title>This is a test of getElementById</title>
</head>
<body>
<div id="area" name="area_name">xxx</div>
<script type="text/javascript">
var divs = document.getElementsByTagName('div');
var msg = '';
msg = 'Divs[0] contains ' + divs[0] + ' with width = ' + divs[0].width + "
";
msg +='Test area width by id = ' + document.getElementById('area').width + "
";
msg +='Test area width by name = ' + document.getElementsByName('area_name').width;
alert(msg);
</script>
</body>

Not Returning Correct Display.
Oct 4, 2007I've created a script that should display a certain image based on the day of the week and the time of the day. After uploading the page to the site I receive no errors, however I'm not getting the display I should be seeing. It always returns the image from the final "else" statement. I'm thinking the problem is that I have two "&&" operators in each "if" statement, and I don't have the proper syntax, or perhaps I'm not writing it properly. Code:

GetElementById() Returning Null
May 25, 2006This function was working in Safari but not in Firefox. I was referencing a couple of elements using the forms[] array instead of getElementById(). I changed those refernces to use getElementById() and now the calculateTotals function does not work in Safari or Firefox.
So I did an alert box to see ucell and it was null. I tried two more alert boxes for the id I was passing to getElementById and for the id of the actual element on the page (which was also created dynamically). They were both identical. The element is created in the onload event, and I am not calling the calculateTotals function until there is onchange event on a text box. So it is not that the element has not been created yet. .

Returning All The Fields In A Layer?
Mar 5, 2003Is there any way of returning all the fields in a layer?
I got a bunch of input fields grouped in different layers inside a form. When someone changes something in one input field in that LAYER, I want it to validate the whole layer, but not the whole form.
Is there anyway of returning all the input fields in that layer as a collection perhaps?
Why Is Function Returning False?
Aug 13, 2011So for whatever reason the convertToArray function in the following code returns false if the argument is more than 1 character long. If it's 1 character long it just returns the character as an array with only one value.What I'm trying to do is take a string of numbers, plus signs, and minus signs and convert it to an array.
View 5 Replies View RelatedGetElementsByTagName Not Returning Values?
Sep 1, 2011My getElementsByTagName ("a"); is not returning anything. (well it's returning "0" not the value I should be getting) I'm asking it to find the number of links on my simple html page. (the reason I'm even doing this is just because I'm trying to learn javascript) but the console in Firefox and the Alert window are just returning "0" when it should tell me I have "4" right?
the files are both located in the same folder, locally
this is my scripts.js file
Code:
var linksAmount = document.getElementsByTagName("a");
alert("Amount of Links:",linksAmount.length);
console.log("Amount of Links:",linksAmount.length);
and this is my html file (it's very small)

Dropdown Menu Returning Value In Box
Apr 6, 2011I have a script for creating 3 dependent dropdown menu.
Selection A in 1st drop Down returns
Selection B in 2nd drop Down which returns
Selection C in 3rd and final drop down
To C I would like to attach a string of 3 value (prices). I was thinking of using the array
var A_B_C = new Array(45, 275, 400);
But I am not to sure how to link it to the code?
Code:
<html><head>
<< script type = "text/javascript" >
var categories =[];
categories["startList"] =["A", "B"]
categories["A"] =["A1", "A2", "A3"];

categories["A1"] =["A11", "A12", "A13", "A14"];

Call A Java
Jul 23, 2005I have a bunch of .js files that I insert into my my html file using
the <script> tag, and this works just fine. The .js files contain
info about the menu, table set up, etc. and take care of the page
format.
But now, I have a tidbit of Javascript in an htm file, and this tidbit
opens up a new window with some information on it. I want to insert
all of the menu and format javascript files on this new window that it
opens. so, my question is: how would I do this: (since this doesn't work!)
output.document.write('<SCRIPT language=JavaScript
src="/scripts/menu_array.js" type=text/javascript></SCRIPT>');

Java Dropdown And XML
May 26, 2009I have a drop down field that is dynamically populated using an XML sheet that looks like:
Code:
I populate the dropdown box using javascript that looks like this:
Code:
My the drop down form looks like this:
Code:
When a user clicks on the drop down box, all of the values inside "<title>" tags get displayed. Once the user has made their selection, the form is submitted and posts the user's option. My problem is that when the user clicks on the drop down box, I want them to see the content included in the "<title>" text but I want the form to post the data included in the "<xml>" tags.
For example, if the user clicks on the drop down menu and selects the option 'Animals' I want the form to post 'xml/animals.xml'. Any ideas how to handle this?

JQuery :: $.ajax Not Returning Data ?
Jun 10, 2009Currently, I'm building a website with jQuery. The function below helps me to get content from a database. In the file content_ajax.php there are some functions to handle ajax-requests. JS calls the PHP-function correctly (I've send an email to myself inside that function to check) but the script doesn't return 'succes' and doesn't give me an error...Also, when I put an alert inside the succes and error function, it doesn't popup!
What may be relevant: - site uses mod_rewrite for friendly url's

JQuery :: Returning A Value When A Button Is Clicked?
Nov 8, 2011I'm working on a small project and want to create a simple dialog window. I know I can use a plug-in, however that is a bit of a over kill plus its a good way to learn more about jquery.
So everything was going well until clicking the button. I cannot find a way to return the value of what button was pressed so I can take further action within the function.
