Simple Form Validation
Oct 15, 2005
I've been playing with this form validation method for a while and have
tried an array of things but haven't had any luck with a couple items.
1. The validateForm() function doesn't detect when the Min price is
greater than the maximum price.
2. The validateForm() function doesn't call isNumber() on the minBaths,
maxBaths, minBeds, or maxBeds.
3. Despite errors in input and the validateForm() function returning
false, the form is still submitted.
Here's the code:

I am in need of some very simple javascript to validate email address and a phone number from a form.
The email address only needs to:
1. Check that the box is not empty.
2. Check that the text imputted contains an '@' symbol.
3. Check that the text imputted contains atleast 1 Period.
The phone number only needs to:
1. Check that the box is not empty.
2. Check that there is no more than 11 characters.
3. check that only numeric characters have been inputted.
I would like it to report (failure) back as text on the page under the box that has the problem rather than a window.

I'm trying to create a simple registration form with ajax validation. I've got the form working almost how I'd like... a message appears on the page with the errors for each field entered incorrectly.
The problem is all the error messages appear in one div together and I would like to have each field have its own div containing only its own error.
I think I need to wrap my error messages in xml and use something like this -
Code:
- but can't seem to get it working
Does anyone know how I should modify my code to do this?
Attached are the 3 I'm currently using
And Here is my code for my ajax page only.

I'm trying to write some validation for a field called Propid, in a form called qSearch. Basically if there's nothing in Propid, or it is says "ref no.", I want to alert the user, otherwise, I want the form to submit.
Here's what I have at the moment:
Code:
<script>
function checksearch()
{
if (qSearch.Propid.value!="ref no." )
{
alert ("Select reference number" );
qsearch.Propid.focus();
return;
}
if (qSearch.Propid.length != 0)
{
alert ("Select reference number" );
qSearch.Propid.focus();
return false;
}
}
}

If the value is equal to 0 it will give an alert and return false. Then if you change the value of the drop down it won't let you submit.

I 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.

All I need is a script to check whether a field contains an exact code. For example,
A user goes through a game, collects pieces of the code - In this case random numbers or letters to form a 9 digit code.
The user can then enter this code into the field, hit submit and told whether they've cracked the code or not.
So basically something like, if this field contains "123456789" then go to WellDone.html but if it contains anything else other than this code then go to BadLuck.html ,
any ideas? Code:

I am trying to do a simple email validation for a form with javascript that doesn't seem to work. I have tried pasting it into both the head and body of my html document. I have also tried unsuccessfully to link it as an external .js file. I have tried numerous scripts that I have found online but none have worked. I am new to programming and don't have much experience with javascript.

I have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.

I'm using the Validation plugin for JQuery and was wondering if there was a function to submit the form without causing it to validate the form. I have a table with a list of radio-buttons and above that is a drop down list of states. The drop down list of states is used to filter the table rows and when the selected item changes it posts-back to the server (via $("#frm").submit()). I don't want this to cause any validation to occur. Is there another function I can call besides submit(), or some other method?

I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it.
The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem.
I am not a Javascript guy more of a HTML/CSS guy and I can manipulate JS to suit my needs.
<problem> I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location. <problem> I would like to keep the JS close to how it is now as I have a library to use this JS over and over again.

I would like to do a simple check if a radio box has been selected.
The form doesn't select any radio box by default, because I don't want to influence the users choice or let them submit the box at all without doing anything.
The form is a simple 5 star rating which means there are 5 radio boxes and a submi button.

I have a problem with a Javascript dropdown form that is supposed to redirect users to the site that is selected. It works fine in IE, but it supposedly doesn't work in Firefox.
If anyone here can point out what is wrong with this code, I would appreciate it. Also, if there is any way to compact the code down or make it cleaner, that would also be appreciated.
<script type="text/javascript">
<!--
function goto(form) { var index=form.select.selectedIndex
if (form.select.options[index].value != "0") {
location=form.select.options[index].value;}}
//-->
</script>
<form name="nav_form">
<select name="select" size="1">
<option value="">Select a Site
<option value="http://www.sitepoint.com/" />Sitepoint
</select>
</form>

I'm quite novice at javaScript but I have a good background in other similar languages, so I find I pick up things quick. Basically I'm planning on reading through some more solid resources on this topic, but I'm kinda under the pump at the moment for something that I imagine wouldn't be too difficult with a lil nudge in the right direction.
I have a form (using PHP) to update a mySQL database AND XML for flash, for a simple news page. At the moment I have the BBcode style of tags ([b][eb]). I was wondering how I can make a rich editor myself with just three buttons (one for italic, one for bold, one for links) that displays the text on screen to the user as WYSIWYG, and outputs the [b] [eb] tags for my PHP code.

I'm having trouble changing the font color of my labels ONLY when I stop the form from submitting due to blank fields. I'm not sure whether if just changing my CSS will achieve what I want, or am I going to have to add somethig to my if else statement, or both? I would think I would need to change CSS to :
label.onfocus {
color:red;
}
but a little confused on what else.

I have a working contact form with 3 of the fields requiring validation and they work well. I have added extra fields to the form (StatusClass, Project, CameFrom). These 3 fields return fine but I need to validated them. My problem is that the new fields don't show in the behaviours/validate panel even though they are within the form tag.
<script type="text/JavaScript">
<!--
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
