JQuery :: How To Implement Empty Item Validation
May 16, 2011
I 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');
}

I want to prevent submitting a form if any of the field is empty. also if possible I would like to validate some basic things. All I want to use JQuery: How do I do that? I have no way and google points me to plugins. The things I want to do are lightweight and I don't need plugin Here is my form:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Login in Site</title>
<link rel="stylesheet" type="text/css" href="/loginsys/site.css" />
[Code]...

I 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?

I am using jquery validate js for my validation. I need to validate and pass the value for the below senario.
I am having a dropdown box which has 2 option. Option 1 and Option 2.
And I have few checkboxes with same name. Depending upon the dropdown selection it should show/hide some checkboxes. Using javascript and CSS these are working fine.
The problem I am having is with the Select All function. If I check Select All it checks the hidden field also. The requirement is to select only the fields which are visible not the hidden one. Please suggest me how to do this.
Example
Here Value 3 and value 4 are common. If I select option Select Item 1 Value 1 will show and value 2 will be hide. If I select all it should not select value 2. As the name is common its selecting that also. It should not select value 2. This is the requirement

I want to say that if the email textbox is not empty, then do the Email validation, which does work on its own. It is part of a function.

I 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?

<script language = "Javascript">
function echeck(str) {
var at="@"
var dot="."
var lat=str.indexOf(at)
var lstr=str.length
var ldot=str.indexOf(dot)
if (str.indexOf(at)==-1){
alert("Invalid Email")
return false
} .....
The form submits even if no input is provided. The database get updated with blank values.

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))))

$(document).ready(function(index){
$(connectSort).each(function(index, obj){
$("." + this).sortable({
connectWith: ".connectedSortable_" + this,
[Code]....
the first function(start: function ..) displays an attribute (title) of the dragged item once the sorting starts. supposedly, the second function (stop: function ..) would display the same attribute but of the item replaced by the dragged item once the sorting stops.
I have tried a lot of things already, but none seems to work.

I have some js code in which a click on a nav arrow causes list to be walked up or down and hilighted. Partial code is below. The problem is that when I get to the end of the list (e.g. there IS no next()), I want to skip this part of the code and actually hide the right arrow. I have no problem with the hiding part - I just want to set a flag when I have traversed the list to the last item.

I want to implement the jQuery GUID Helper plugin into my web app but I don't know what's the "best practice" method of incorporating it into my code.I'm basically creating a cart system from scratch (figured it was asufficientlycomplicated system to use when learning jQuery). When the visitor first adds an item to their cart is when I wanted to create the GUID for the visitor. I have a cart-handler.js script that I link to from the item view page:
<script type="text/javascript" src="/js/cart-handler.js"></script>
That script's first line is my$(document).ready(function(){ and the script handles AJAX calls to loading the data into cart record in my MySQL database, updates the cart total on the items page, and changes the button from "Add Item" to "Update Quantity".So would I need to link to the jquery.Guid.js script right from the view items file for my item view page? Or can I reference the plugin from the cart-handler.js file?

I am trying to implement a version of the datepicker. However, I would like the calendar to open in a modal dialog box rather than sliding open next to the text box.This is the closest example I've been able to find, but there are a few issues - I would like the user to click on the text box to change the input, and obviously the small input box in the corner of the calendar is a problem...

I can write the most basic codes but even then it really doesn't make sense. On my website I am trying to implement a JavaScript slideshow from this website: [URL]. I do everything as it says, but the images don't even show up. Here is a link to my website where the problem is, you can view the source to see my xhtml code (please note my site isn't even close to being done.): [URL]. The slideshow should be showing up in a right next to where it says "Design is our Passion."
Here is the code for the slideshow which the site I got the script said to do:
<div id="slider">
<img src="Assets/slideshow_assets/stereosound.jpg" alt="" title="Business Card design for StereoSound." />
<img src="Assets/slideshow_assets/triflex.jpg" alt="" title="Logo design for TriFlex Labs." />
</div>
Here are both of the CSS files that the slideshow uses:
nivo-slider.css:
/*
* jQuery Nivo Slider v2.0
* [URL]
*
* Copyright 2010, Gilbert Pellegrom
* Free to use and abuse under the MIT license.
* [URL]
*
* March 2010
*/
/* The Nivo Slider styles */
.nivoSlider {
position:relative;
}
.nivoSlider img {
position:absolute;
top:0px;
left:0px;
} .....

Having some problems trying to implement the frameReady plugin for jQuery, has anyone used it successfully? Support seems to have dried up a few years ago and I don't think the normal javascript way of targeting iFrames is going to be flexible enough to service my needs!

The first row of thumbnails does what I want. I have the couple function:
And the HTML source is:
But this means the A elements have to be a direct descendant of thumbnails. I would like all A descendants to be overridden, so I can do something like:

Is this possible?

I'm trying to implement a simple menu with html + jquery. I have a standard html table as the main menu bar at the top of the page. Up until now the menu was only 1 level deep. However, now there have been multiple reports added so these new reports need to be added as Report submenu items.
I've created some additional table rows with cells that align under the Reports menu item. Then I've wired up the mouseover event of the Reports cell to display the report submenus underneath it.
What's the best way to hide the submenu items when that part of the menu loses focus? I've wired up the onmouseout of the main Reports menu item to hide the submenu items but this isn't right because the user should be allowed to move focus from the main menu item to the submenu item without the submenu items getting hidden.
Also, when I dynamically show the submenu item rows this pushes down the rest of the content on the page. How can make the submenu table rows *overlay* the page content below it?

I have autocomplete working for a list of colors(red, green, blue, etc). I created an array of $id's to match each color. For example if someone types and selects "red", I want it to go to a page like mypage.php?id=1. How can I (1) parse the ids in the array and (2) implement the result()
function so that it links to a page and posts the proper $id? I have a live example with source code here: [URL].. and if you would be kind enough to be as explicit as you can with examples on how to make an autocomplete result link to a page and pass an $id.[URL]..
