No Empty Entries For Textbox & Listbox Validation
Jan 28, 2010I have this form that validates a few textboxes & a dropdownlist. And when it is not filled in, the border of the textboxes and dropdownlist would turn red, followed by an alert message notifying which field have not been filled in.Else, the border will revert back to black, and the form will be submitted successfully. Right now, I would like to prevent the user from entering blanks (like entering a space to cheat the system). How should I tweak the codes to make it work?

Jul 28, 2010I am using the jquery validation plugin to validate a form's email address field. The validation works but with the minor exception that when trailing whitespace is entered after the email the validation fails. I'm not sure if this is because of the regexp or a missing trim.

View 1 Replies View RelatedChange Textbox Value With Script Only When It Is Empty?
Feb 1, 2011I've been teaching myself HTML and CSS for a while, and now I've moved into the world of Javascript (but I'm still very much a beginner). For practice, I've been building a sample sign up form for a mock website, and I'm having problems with the birthdate section. The idea I had was to have MM, DD, and YYYY be the default values of my 3 textboxes (as an example for users), then set the value to nothing when the box gained focus. That all works fine, but I ran into problems when I tried to write an if statement to set the value back to MM, DD, or YYYY if the value was still nothing when the user clicked away. As it is now it just replaces the text inputted into the textbox (which of course is not good). Any ideas for what the problem might be? code...
Another side question, if I set a variable equal to the value of a textbox, then change the value of the variable, does that also change the value of the textbox? or is the variable no longer associated with the textbox. Example code...
does document.form.textbox.value = blue? or is var a now completely independent of the textbox value?
JQuery :: How To Implement Empty Item Validation
May 16, 2011I am using jquery autocomplete to retrieve values from database I need to implement empty item validation the point is that if there is no value in database user can insert it with bottom which appears somewhere in form. I try to usesearch: function () but can't figure out how to catch item length.
Code:
,search: function(event, ui) {
//Your ajax parameters...
//success: function(data) { //No idea what format your data is in...
// if(data['status'] == false) { //there is no result
//if ( ui.item == '')
//{
//alert(ui.item.value);
//}
if (ui.length < 2) {
// handle no data case specially
alert('test no date');
}

JQuery :: Skip Validation For Fields With Empty Class
Oct 21, 2010I am using the validate plugin with the defaultvalue plugin (empty fields given a default value and class of empty), and would like to use it together with the validator plugin. Is there a way to mark required fields with only the default value (and class empty) as invalid on submit?
E.g.: First_name field is required by validate, has a default value of "Enter your first name" and class of "empty" - how can I get the validator to mark this as invalid?

Aug 3, 2006I have a form which mostly works and validates with javascript Name, details, email, etc.
However the email bit is happy to validate with just @. instead of a@b.net/com/whatever.
It's probably a really simple fix, but I'm still new to javascript.. Hopefully someone can point out what I need to add / change in the following section of script.
if(form.email.value=="")
{
alert("Please Enter Email Address");
return false;
}
if(form.email.value!="")
{
str=form.email.value;
var AtTheRate= str.indexOf("@");
var DotSap= str.lastIndexOf(".");
if (AtTheRate==-1 || DotSap ==-1)
{
alert("Enter Proper Email Address");

else
{
if( AtTheRate > DotSap )
{
alert("Enter Valid Email Address");
return false;

Email Validation With Apostrophe?
Feb 2, 2010Whoever allowed apostrophes to be valid within emails needs some talking to!
Anyway. I have just found out that this JS function I have been using and have no idea how it works does not allow emails with apostrophes in it. Does anyone know how to alter this code to allow apostrophes?
var pattern = new RegExp(/^(("[w-s]+")|([w-]+(?:.[w-]+)*)|("[w-s]+")([w-]+(?:.[w-]+)*))(@((?:[w-]+.)*w[w-]{0,66}).([a-z]{2,6}(?:.[a-z]{2})?)$)|(@[?((25[0-5].|2[0-4][0-9].|1[0-9]{2}.|[0-9]{1,2}.))((25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2}).){2}(25[0-5]|2[0-4][0-9]|1[0-9]{2}|[0-9]{1,2})]?$)/i);

View 1 Replies View RelatedEmail Validation: Just Enough To Prevent Sql Injection
Oct 28, 2006I've read enough about email validation to know that the only real validation is having a user respond to a confirmation message you've sent them. However, I want to store the address temporarily, so I want to make sure what is entered is safe to work with.
I have a basic understanding of regexps, so I could write one that checks for a simple
format like: something followed by @ followed by something followed by
.. followed by something. I can also make a good guess at understanding
the regexps I come across in validation schemes people have posted.
However, each scheme that is posted seems to get criticized for
invalidating some esoteric, but valid, addresses.
I'm wondering if there is a minimum validation you can do that will
prevent basic attacks like sql injection attacks. For example, if I
weed out anything with single and double quotes, and semicolons, am I
barring some people unnecessarily? Seems like you'd be trying to mess
with people by putting a semicolon in your email address.

Simple Email Validation Function
Jan 14, 2007I am a Javascript newbie and I'm trying to implement a very simple form validation function, but for some reason it won't work. I must be doing something fundamentally wrong here. Maybe somebody can hint me into the right direction? My code looks like so:
function validate_form ()
{
valid = true;
var re = new RegExp();
re.compile("[A-Za-z0-9._-]+@[^.]+..+");
if ((document.form.author_name.value == "")
|| (document.form.author_email.value == "")
|| (!re.test(document.form.author_email.value))
|| (document.form.author_message.value == ""))
{
alert ("Please fill in all required fields.");
valid = false;
}
return valid;
}
The tricky bit is the email validation using the regular expression. Apart from that it all works.
