I'm working on a program, it's a java servlet. It's interacting with an oracle DB. I need to add users and privaledges to the DB, but do not want people typing random usernames, I need to force them to use their company ID, i.e jmsmith, which is the username they log into their terminal from.
What I need to know, is there anyway possible to grab their current username from windows? i.e. a query to windows to see what user is currently logged into the terminal?
I'm creating an AJAX user validation so that when a user types in a username, it checks it in the database to see if it exists. I want it to execute after the user finishes typing. I've tried using:
$("#username_field").keyup(function(){
which works, but I don't want a query executed every time the users presses a key. I was wondering if there was a better way to do it. Meaning I what the check to be preformed after the user finishes typing.
I am a student and new to JavaScript, my problem is I am willing to do JavaScript form validation for emails , text etc. But on one of the forum I found out JS is not a very good way to do validation as JavaScript can be easily turned off by end-user and we shld always do server side validation also, but due to some concerns I want to stick to JavaScript (client side) validation.
My scenario is somewhat like Ive a form and a button in it which on being clicked calls a JavaScript function that will validate the fields and then submit the form through form.submit(); So my question is if JavaScript is turned off on end user then with validation the end user will also be not able to submit the form as the form is being submitted in a JavaScript function (which is turned off)? If this is thn cool.
But is it somehow possible to hack this procedure, and one can skip the JavaScript validation but can still submit the form? My primary concern is not to let pass any malicious or improper data (sql-injections, poorly formatted strings etc. to the server db)

View 1 Replies View RelatedI am looking to add an email validation to my new user registration form. Currently, we do not validate (or activate) a new user via an activation link in the email. We don't have that process. I'd like to get my hands on the code to randonly create a security code and the actual code to sent the validation email. Can anyone help me out here? I'm absolutely new to PHP or ASP coding. I do know some HTML.
View 5 Replies View RelatedI have recently downloaded the jQuery Validation Plugin, and I want to use the bottom part of the demo [url] (Validating a Complete Form) and I have some questions to ask:
1. I want the validation to work after the user clicked "Submit"
2. If a column is wrong (username already taken or password length invalid) I want not only error message but also a picture in front of the error message.
3. I hope that after the user clicks "Submit" and then found a column is wrong then correct it, after the user corrected it and click to other place or other column the validator starts again to check the column the user just edited whether the user just corrected a wrong column or edited a correct column into error.
4. I hope to display a image in right of the column if that column is correct after the validator works.
In a registration form middleName field is optional. When the users enters his/her middleName, then it should validate that field. I have used the following code to achieve the above scenario, but it is not working.
$("#middleName").rules("add", {checkName: true, required: false, messages: {checkName: "Please enter a valid middle name"} });
jQuery.validator.addMethod("checkName",
function(value, element) {
var regExp = new RegExp(/^[a-zA-Z0-9s|,|.|-|']+$/);
return regExp.test(value);
},
"Please enter a valid name."
);
How to achieve the above scenario.
Im developing a JSP site... my user information validation page is not working and its giving that responseXML object is null...Im not using any XML file to fill the data here.... all the messages custom messages are loaded from the JSP page....My Valildation.js file as below.....

In my form I have a couple of text fields into which the user enters

I want to do a form validation and it should return a message like "should not be empty" when the user leaves the field blank..
I have html code like this
Now I want to know how can i display alert message to the user saying that the particular label name should not be empty..
For eg.. here I want to display alert as "Did you find this article useful? field should not be empty".... (Assuming this is mandatory)
I have so many fields like this in my form(checkbox, radio buttons, etc...) and i want to display alert with label name...
How can I do this using javascript.. (I know how to do validation in javascript popping up the alert(without label name), But I am not sure how to display alert with label name))))
I will like to know if there is anyway to view all the rules that I have currently in the Jquery validation plugin. Currently, I am trying to add in rules dynamically through the rules(add) function after adding some dynamic fields through the user inputs. the rules are added in this manner.

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 4 Replies View RelatedI have a formdivided into 2 fieldsets (see the image) : MASTER and DETAIL. When I press Add in the DETAIL fieldset a new item is added to an array where I store temporarly the data entered trough the DETAIL inputs and finally when I press save I send both the MASTER and DETAIL (the temporary array shown in the html table) data to the server. As you may have already noticed, I need to validate both MASTER an DETAIL, but I don't want the Save button to fire the DETAIL validation or the Add link to fire the MASTER validation. I've been googling for a while and though I couldn't find exactly what I've been looking for, I found that it's possible to add/remove a class (e.g, required, number); that gave me some ideas on how to simulate validation groups and here's the code:
<script>
$
(
document
[Code]...
Although this code allow me to stop the MASTER validation from firing when I press Add( and DETAIL validation when I click Save), I still can't manage to insert a new DETAIL if only if all of the inputs in the DETAIL fieldset are valid and, what's more I don't want the Add link to cause a form submission.
I have a select box with and onchange event to get the data from serever, <SELECT name="States" id="State" onchange="getData(this.value)" > Now i want to validate that if no value is selected from the above list, then it should not send the ajax request. How can i apply the Jquery validation plugin here?
View 4 Replies View RelatedI 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 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?

I have read all posts about how to detect that url have changed to new
page and trigger the event handler then eg.
function aidLogout(evt) {
if(evt) {
/* maybe via analyse of evt object i can detect the close of the
browser window */
}
if(window.event) {
/* maybe via analyse of window.event object i can detect the close of
the browser window */
}
var i = new Image();
i.src = "aidlogout.asp?uid=1562&SessionID=ABCDEFGHIJKLMNOP"
} /* assuming that aidlogout.asp will return nothing or empty image */
window.unload = aidLogout;
/* or via
if(window.addEventListener) {
window.addEventListener("unload", aidLogout, false);
} else
if(window.attachEvent) {
window.attachEvent("unload", aidLogout);
}
PS i know about super Gecko onclose event which fires when browser
window is closed, but i could not find such method in IE.
I've put together a pretty simple competition script - it's commented out below and you can find the demo at [URL] (you'll find the code at the bottom of the page) I am using a jquery plugin to achieve the validation: [URL] The problem is only in Firefox (3.5.2) - the form submits without any validation at all, and ignores the ajax. IE8 & 7 seem to be fine. I'm not really sure why Firefox is submitting the page with Refresh but IE isn't, I've looked over and over the code and can't find the error. Firebug is only finding errors in the jQuery library itself.
