JavaScript - Concat A $ Sign
So how do add a dollar sign the the front of total??
Code: total = round_decimals(order_total, 2) total = "$" + total; Similar TutorialsHi. I'm fairly new to javascript. I have a code where I'm trying to generate scrollx1 through scrollx100. I can get the array to work with doc.write and I can get one concat variable to work in the element but when I combine them it doesn't work. Any suggestions as to what I need to add to this code: var sp=1; for (sp=1;sp<=100;sp++) { var sx = "scrollx"; var sy = "scrolly"; var thissx = sx + sp; var thissy = sy + sp; theForm[thissx].value = scrollx; theForm[thissy].value = scrolly; } Any help would be much appreciated!!

Any help would be much appreciated!! hi. i know php but learning javascript. can anybody give me a reason why i might not wanna use the php practice of beginning every variable_name with a dollar-sign: $variable_name??? i am just accustomed to seeing my variables beginning with a dollar_sign. Thanks. Hello all, Please I need help, I have a php form with different fileds. I have a field called description. The description field should only contains pure text, no numbers, but my users are entering phone numbers and email addresses into this field despite to the fact that there is already dedicated fileds for email and phone. What I want is a javascript funtion or php function that will automatically delete the numbers or @ from the field or prevent entering numbers and @ signs on this particular field. Many thanks in advance for your help. I almost got part of this one program to work. It is of a golf sign with a golf ball moving across and landing in the word Golf into the "o" When the ball lands in the o the sign of "your online source of golf equipment" appears after ball has landed and grows in size. right now the ball is what I have but I can not get my sign to appear. I use 2 external files I will post all the coding here here is my main file I worked on this is my golfpage.htm file Code: <html>

What i am not able to get work i think is to call the changeFontSize() function to increase the size of the "sign" also an if statement to test value of fs variable is less then equal to 20 how do i get my sign to appear on the output? thanks I really don't know what I am doing, but I need to know how to alter this script to load this website without having to click "Weathersentry online". I would like to double click on the icon the code is attached to and it sign in automatically.

Looking for some help/advice please. Imagine a wife has signed on to a web site in a browser tab. She does not sign off and walks away to do something else. Her husband sits at the computer and seeing her signed on, opens a new tab and tries to sign on to the same site. I am trying to write a script that will close other tabs/windows when the husband goes to the same site to sign on. So, on the sign on page (or even better, the sign off page), when the sign on button is clicked, a piece of Javascript code is run first. The javascript simply goes through all tabs on the browser, and checks to see if any such tabs has an HTML document that came from the same domain as the sign on page. If such tabs exist, then before POSTing the user name and password to the server, the Javascript code will close those tabs that contain HTML documents came from the same domain. So, I understand I need to set the window.name to a specific value. But does anyone know what the code on the sign on/sign off page to close the other tabs/windows would look like? Thanks so much for any and all help. Hi there, I would like to allow the "+" sign in my 3 textboxes. When the user does not put the "+" sign in the textboxes, and it is being validated, the system will allow it to pass. Also, it must check that it has at least 8 digits.
