View 3 Replies View RelatedSo I want to be able to check the last 15 characters of a string for either <br /> or a space. I know how to do this with PHP but I have no clue how to do this with Javascript and Google is failing me. Could someone point me in the right direction?
Example string: var string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
I'm assuming this will be done with lastIndexOf but I do not know how to do it. So to reiterate, I want to check to see if either a space exists, or <br />, delete everything after that, and return the string. So the output of the example string would be...
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
I am doing some basic form validation stuff and I have two fields (phone, fax) that I need to check if the characters enterred are numeric, but still allow + and () characters to be enterred. If anything else has been enterred to display an error message.
Can someone point me to a resource ( I searched, but couldn't find an obvious one!) or give me a rundown on some code here to help me out?

View 24 Replies View RelatedI am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'
I have a code that I got from a tutorial website. The goal is when someone clicks the first check box with the value of yes then the two other sets of check boxes will autmatically be checked for no.
The issue is their are three sets of 2 check boxes each.
So here is my code code I am trying to use
PHP Code:
Here is my form code
PHP Code:
So Ideally when a representative clicks that the customer has three services (clicks the Yes checkbox) all the other checkboxes will default to No.

I don't know why it's not running the validation js first upon "submit", it goes straight to the "thankyou" page specified by the php (let me know if php needs to be posted). I've check my syntax over and over, I can't see anything.
I'm trying to have a "tell-a-friend" form where one requires to enter his/her first name, surname, email and a friend's email � with option of forward to to other 4 friends (total 5).
Here are the fields I need to validate:
My js (validationB.js) file:
I have to check for several possible values of a variable and I currently do it like so:
(SHIP_TYPE == "M" || SHIP_TYPE == "S" || SHIP_TYPE == "X")
But this seems overly manual to me. I'm imagining something like the SQL "IN" function:
SHIP_TYPE IN ('M','S','X')
Does such a thing exist in JavaScript, or do I need to write my own function?
I have developed an application in PHP.The user will find the list of experts and this code is generated based on the experts data in database.. It is working fine..

Now he enters the question, he needs the reply and then he clicks on submit button.An email must be sent to the expert I need the javascript to find whether the USER CHECKED the Check boxes or NOT.

I have a form script that is made up of Text boxes, radio buttons, and drop down boxes. What I am wanting to happen is upon clicking submit at bottom of form, it should run a check to make sure all questions have been answered. So far it catches all the text boxes, but it's not catching the radio buttons or drop down boxes.. I have all of this under 1 form name ( is this where my problem is located? do I need to seperate into different form names based on type?) I am not wanting the answer given too me ( at least not yet ). I have done a search for multiple types of validation. But nothing seemed to clcik... Also Do I need another validation set up point for the Month, Date, year Drop down boxes?
