GetElementById - Run Function If ID Contains Price

Jan 1, 2010

Is there a way for getElementById to perform a function if it finds an ID that is like something - sort of like a wildcard? I want the function to run if the ID contains "_price". It will have something like 247_price or 23_price. I want to ignore the first number and only concern myself with whether or not it has "_price" in it.

Code:
if (document.getElementById("LIKE_price")) {
//do this
} else {
//do this
}

Document.getElementByID Not A Function?

Apr 18, 2002

I've got the following code on one of my pages, it works fine in IE6 and Netscape 6.2, but when you get around to using it on Netscape Navigator 4.08 it doesn't work, instead giving me a "document.getElementByID is not a function" error. Here's the code it has a problem with...

function CrseDets(IDS) {
window.open('coursedetails.asp?whereby=' + document.getElementById(IDS).value,null,'top=0,left=0,width=672,height=500, background="gfx/backgrd.gif", scrollbars=yes');
}

GetElementById Function - ID Is Null

Sep 16, 2011

Why this simple script is not working. Trying to use getElementById() but Firebug says the ID is null. I've tried troubleshooting by accessing other ID's but they all come back 'null'. Trying to add 2 classes based on an ID:
<script>
pageId = 1;
if(pageId == 1) {
//alert('This is page' + pageId);
document.getElementById('arta').setAttribute("class", "menu-on menu-a");
}
<./script>

An online example is here: [URL]. I also tried accessing the id like below but got the same result:
document.arta.setAttribute('class', 'menu-on menu-a');

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).

GetElementById Checked Radio Button For Function

Nov 28, 2010

I have a choice of three market items and I want the value of the selected one to be sent to my form. My code is:[code]I have tried giving them different ids, I have tried replacing the id with checked="id='myitem'", I have tried getElementById('myitem.checked'), I have tried getElementbyName.In my full page I have far more radio buttons, so I don't want to do a getElementById('myitem[0].checked || myitem[1].checked etc.But I have run out of alternatives to try. Needless to say as it currently stands it gives the last radio button's value, which means it doesn't like them having the same id, but when I tried changing how the id was applied, or called - ElementByName, FF gives the error message as id is null.

Element.getElementById Instead Of Document.getElementById

May 13, 2004

I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.

In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.

Price Calculator

Jan 4, 2007

I am trying to create a price calculator that automatically calculates the price of custom made picture frame. I got an equation that finds the square area of the frame by multiplying the perimeter (2*length*width) by the thickness (which the user can choose from 1.5", 2" or 3"). Then it multiplies it by a decimal number (0.27 if the frame is 1.5" thick, 0.23 if its 2" thick, and 0.18 if its 3" thick). Then it adds a $5 custom made fee to the final answer. But when I save it to an html file and load it in Internet Explorer, it doesn't calculate. Code:

Program To Calculate Price With Sales Tax?

Oct 8, 2011

When I compile this I get no errors, however when I try to run it, it does not work. What should happen, is an output dialog box should appear saying the total for tickets, total tax, and total for tickets with tax. This is not what happens. This is what I have written: This program will ask for the number of tickets you wish purchase. It will then calculate the total price of the tickets and the 9.5% sales tax.

import javax.swing.JOptionPane;
public class TicketCost {
Constants
static final double TICKET_PRICE = 10.00;
static final double TAX = .095;
public static void main (String [] args) {
Local variables
int Nbr_Tickets = 0;
double Tax = 0;
double Total = 0;
String InputStr;
String outputMsg;
InputStr = JOptionPane.showInputDialog
("Enter the number of tickets to purchase");
Nbr_Tickets = Integer.parseInt(InputStr);

Calculation
Nbr_Tickets = (int)(Nbr_Tickets * TICKET_PRICE);
Tax = Nbr_Tickets * TAX;
Total = Nbr_Tickets + Tax;

Created message
outputMsg = "cost of tickets: $"
+ String.format("%.2f", Nbr_Tickets)
+ "Taxes: $"
+ String.format("%.2f", Tax)
+ "Total cost of tickets to A Beautiful Mind: $"
+ String.format("%.2f", Total);
output message
JOptionPane.showMessageDialog(null,outputMsg,"Total cost of tickets to A beautiful Mind",JOptionPane.INFORMATION_MESSAGE);
System.exit(0);
}}

And when I run it this is what I get:
----jGRASP exec: java TicketCost
Exception in thread "main" java.util.IllegalFormatConversionException: f != java.lang.Integer
at java.util.Formatter$FormatSpecifier.failConversion(Formatter.java:4045)
at java.util.Formatter$FormatSpecifier.printFloat(Formatter.java:2761)
at java.util.Formatter$FormatSpecifier.print(Formatter.java:2708)
at java.util.Formatter.format(Formatter.java:2488)
at java.util.Formatter.format(Formatter.java:2423)
at java.lang.String.format(String.java:2845)
at TicketCost.main(TicketCost.java:35)
----jGRASP wedge2: exit code for process is 1.
----jGRASP: operation complete.
