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?
This has been asked before, and i've seen many of the previous posts. And tried for hours. But finally i've broken and have to ask for help. What am I doing wrong here?
var u=document.forms["lead"]["name"].value;
var v=document.forms["lead"]["city"].value;
var x=document.forms["lead"]["country"].value;
var y=document.forms["lead"]["mobile"].value;
var z=document.forms["lead"]["email"].value;

I 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 the following code that i am using to try and prevent users from entering non-numeric characters but it doesn't seem to work:
PHP Code:
function validate_onkeypress() {
a = String.fromCharCode(event.keyCode);
b = a.charCodeAt(0);
if (!validateString(b)) return false;

I am having problems with the code below (obviously) coming up with illegal character for various characters within the field name
which is: S_Gift Finder1_0
I have tried various ways of escaping the characters but to no avail.
I am unable to change the name of the field as it it comes from an external off-the-shelf package. Code ....
I'm trying to add a text box to a form that has some other complications. My "mcomment" in the code below does work but will only accept numbers, and the whole idea was text.
Code:
function n_od(type) {
var f = document.forms.create_account;
$("#id_od").html("<img src='images/nr_loading1.gif' border=0>");
subcat3 = escape($("#subcat3").val());
if (type == 2)
$("#id_od").load("n_autos.php?step=115&w="+f.width.value+
"&fractionw="+$("#fractionw").val()+"&length_in="+f.length_in.value+
"&fractionl="+$("#fractionl").val()+"&mcomment="+f.mcomment.value+
"&mcat="+$("#mcat").val()+"&subcat="+$("#subcat").val()+"&subcat3="+subcat3);
else {
$("#id_od").load("n_autos.php?step=116&w="+f.width.value+"&fractionw="+
$("#fractionw").val()+"&length_in="+f.length_in.value+"&fractionl="+
$("#fractionl").val()+"&mcomment="+f.mcomment.value+"&mcat="+$("#mcat").val());
}
}
I am trying to add numeric validation to a field that I generate once a button is clicked. The code is:
function addFormField()
{
var id = document.getElementById("id").value;
$("#appendTable").append(
"<div>"+
"<table width='820' border='0' cellspacing='0' cellpadding='5' align='left' style='margin-top:10px;margin-bottom:10px;margin-left:-2px;clear:both;'>"+

View 10 Replies View RelatedQuestion 1: I have a spinner function and I have one slight problem with it. If a user types in 00000009 or 00021 in the spinner for example, if the user clicks away from the spinner, it will still display 00000009 or 00021 in the spinner. What I want is that if something like this happens, then what I want is that when the user clicks away, I want the spinner to display it as 9 or 21 rather than 00000009 or 00021. I don't know how to do this though. Does anyone know how to overcome this:
Question 2: If I used backspace to remove a number from a spinner and that is left with a blank spinner, what needs to be done so that if I click away from the spinner, the last number in the spinner re-appears in the spinner?

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

View 8 Replies View RelatedI have an email which has some values attached to a link in the email that get passed to an online form on a website when clicked. Problem is the value is a price and the string includes a "$" which I need to remove. I've read through many examples and everyone seems to have an opinion (surprise). One suggests something like this: text2.value=text1.value.replace(/$/g,""); While someone else says its better to remove what you don't want. I am also scratching my head over should I place the value into a hidden field, scrub it then copy that into the proper field? and I imagine the best way would be to run it with an "onload" command instead or a event handler like a keystroke since the field is not typed?
