Is there a way of trimming the value before checking it so that a space for example would still be NULL "".
Code:
if(document.sendmail.emailsubject.value == '')
{
msg += "Subject cannot be left blank.
";
error = true;
}
is there any way to trim the filed value before using jquery validate plugin [URL]../Plugins/Validation/Validator.

I have the following script that converts line breaks from plain text into HTML formatted paragraphs. It takes plain text from one text area field and outputs the new formatted text into another text area field.
function convertText(){
var noBreaks = document.getElementById("oldText").value;
noBreaks = noBreaks.replace(/

I have a text field that I wish to cellect numbers of bird seen. However,
some folk want to use 'c' before the number or '+' after to indicate a fuzzy
number. I have tried creating a function that checks for each of these and
still validates the rest as a number: Code:
What I have right now is when someone hits submit,text appears next to the textarea that says..Please enter an email..That all works fine,but what I would like to do is have the value that I have in the textfield,that has a text style applied from my style sheet(now grey) to turn red,maybe if I made another style inside the CSS file which would be for red text.
Would that be possible? to have one style in the css file,change to another with the javascript?

View 2 Replies View RelatedI have written a form in HTML which contains username,lastname,email,password and submit.I have written a javascript to validate this form [validate(username,lastname,,password)].On submit this javascript function will be called and hence form get validated. I am passing all the arguements(username,lastname,email and password) to the javascript function..Is it possible to make me a code such that it should call an individual function for each field in the form.for ex:if i have not entered username, last name in the form and attempt to submit, only username arguement should be passed to the function as it comes first in the form.In other sense i want to validate individual text field validation of my form.

how would I reference the contents of the text box in a separate Javascript file? I have tried document.form.UserInfo.value and many, many variations and just can't get it to work. I presume it has something to do with the paragraph having the same name?
I have a form set up and I need to set the validation so if one option is selected from a picklist, they need to complete a text field as well.
This is the code i'm using:
Code:
Reason is a picklist, I want it to show the alert when option 1 from the picklist is selected and no text is in the Row_Number field.
If any of the other options are selected, I want to make sure the Row_Number field is blank.
As I said, I'm sure this is a very simple thing, but I been working on it for ages, and cannot get it to work, I get the alert every time the Row_Number field is blank.
How do i begin a validation script for a form with radio buttons & check box & text area.

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.

View 2 Replies View RelatedI'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?

View 1 Replies View RelatedI 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.
Having a few problems with a form validation script. Its supposed to stop sending the form if key fields are missing, but it just sends them anyway!
Below is the code i use in the header to check for blank fields:

From what i can see the fields match, it all links up correctly but still it will allow blank forms to be sent.
Does java script provides inbuilt trimming function, if not then what
is the solution.
How do we trim out or remove a part of a URL or path?
eg. http://www.mywebsite/folder/somefile.htm ----I want to trim
http://www.mywebsite/folder/ so All I have left is the file name.
<script language="JavaScript">
var pathtotrim = location.href;
document.write (pathtotrim);
</script>
Is there really no string trim function in JS?
Code:
function trim(s)
{
return rtrim(ltrim(s));

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 am having serious issues with this script, either it won't execute at all (the form doesn't work, as well as the validation) or the form submits without validating the form.
