I am using a plugin for live search .. everything is working fine .. i just want to add a loading png that appear on start of ajax request and disappear on results ..
please help me to customize the code just to add class where form id="search-kb-form" .. and remove the class when results are completed.
<form id="search-kb-form" class="search-kb-form" method="get" action="<?php echo home_url('/'); ?>" autocomplete="off">
<div class="wrapper-kb-fields">
<input type="text" id="s" name="s" placeholder="Search what you’re looking for" title="* Please enter a search term!">
<input type="submit" class="submit-button-kb" value="">
</div>
<div id="search-error-container"></div>
</form>
This is the plugin code

add a background to the loading class
.loading {
background:url('http://path_to_your_picture');

jQuery.fn.extend({
ytv: function(options) {
return this.each(function() {
new YTV(this.id, options);
});
}
});
}
}).call(this, window, document);
Replace this
list += '<div class="ytv-list-header">';
with
list += '<div class="ytv-list-header ytv-playlist-open">';
There is two playlist one is "list of all playlists". And other is "list of videos in a playlist".
"ytv-playlist-open" indicate the open status for "list of all playlist". So when it is added it will close "videos in a playlist" and show "list of all playlist" which you want to show there.
The question is very simple but also a bit theoretical.
Let's imagine you have a long JQuery script which modifies and animate the graphics of the web site. It's objective is to handle the UI. The UI has to be responsive so the real need for this JQuery is to mix some state of visualization (sportlist visible / not visible) with some need due to Responsive UI.
Thinking from an MVC / AngularJS point of view. How should a programmer handle that?
How to refactor JS / JQuery code to implement separation of concerns described by MVC / AngularJS?
I provide an example of JQuery code to speak over something concrete.

My steps in such cases are:
First of all write (at least) one controller
Replace all eventhandler with ng-directives (ng-click most of all)
Pull the view state out of the controller with ng-style and ng-class. In most of all cases ng-show and ng-hide will be sufficed
If there is code that will be used more than once, consider writing a directive.
And code that has nothing todo with the view state - put the code in a service
write unit tests (i guess there is no one until now:) )
I have this code embedded in my file for managing session time out. This was referred from http://www.fairwaytech.com/2012/01/handling-session-timeout-gracefully/
I want to call SessionManager.extend() for all the ajax request
complete. So i can automatically refresh my session manager time.
This is what i tried
<script type="text/javascript">
$(document).ajaxSuccess(function (event, xhr, settings) {
if (xhr.status === 200) {
SessionManager().extend();
}
});
</script>
Getting an error that SessionManager object not found. How do we call this?
Below is the library code taken from that site
$(function () { // Wrap it all in jQuery documentReady because we use jQuery UI Dialog
// HtmlHelpers Module
// Call by using HtmlHelpers.getQueryStringValue("myname");
var HtmlHelpers = function () {
return {
// Based on http://stackoverflow.com/questions/901115/get-query-string-values-in-javascript
getQueryStringValue: function (name) {
var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
};
} ();
// StringHelpers Module
// Call by using StringHelpers.padLeft("1", "000");
var StringHelpers = function () {
return {
// Pad string using padMask. string '1' with padMask '000' will produce '001'.
padLeft: function (string, padMask) {
string = '' + string;
return (padMask.substr(0, (padMask.length - string.length)) + string);
}
};
} ();
// SessionManager Module
var SessionManager = function () {
// NOTE: globalTimeoutPeriod is defined in _Layout.cshtml
var sessionTimeoutSeconds = HtmlHelpers.getQueryStringValue('smt') || (globalTimeoutPeriod),
countdownSeconds = HtmlHelpers.getQueryStringValue('smc') || 300,
secondsBeforePrompt = sessionTimeoutSeconds - countdownSeconds,
$dlg,
displayCountdownIntervalId,
promptToExtendSessionTimeoutId,
originalTitle = document.title,
count = countdownSeconds,
extendSessionUrl = '/Session/Extend',
expireSessionUrl = '/Session/Expire?returnUrl=' + location.pathname;
var endSession = function () {
$dlg.dialog('close');
location.href = expireSessionUrl;
};
var displayCountdown = function () {
var countdown = function () {
var cd = new Date(count * 1000),
minutes = cd.getUTCMinutes(),
seconds = cd.getUTCSeconds(),
minutesDisplay = minutes === 1 ? '1 minute ' : minutes === 0 ? '' : minutes + ' minutes ',
secondsDisplay = seconds === 1 ? '1 second' : seconds + ' seconds',
cdDisplay = minutesDisplay + secondsDisplay;
document.title = 'Expire in ' +
StringHelpers.padLeft(minutes, '00') + ':' +
StringHelpers.padLeft(seconds, '00');
$('#sm-countdown').html(cdDisplay);
if (count === 0) {
document.title = 'Session Expired';
endSession();
}
count--;
};
countdown();
displayCountdownIntervalId = window.setInterval(countdown, 1000);
};
var promptToExtendSession = function () {
$dlg = $('#sm-countdown-dialog')
.dialog({
title: 'Session Timeout Warning',
height: 250,
width: 350,
bgiframe: true,
modal: true,
buttons: {
'Continue': function () {
$(this).dialog('close');
refreshSession();
document.title = originalTitle;
},
'Log Out': function () {
endSession(false);
}
}
});
count = countdownSeconds;
displayCountdown();
};
var refreshSession = function () {
window.clearInterval(displayCountdownIntervalId);
var img = new Image(1, 1);
img.src = extendSessionUrl;
window.clearTimeout(promptToExtendSessionTimeoutId);
startSessionManager();
};
var startSessionManager = function () {
promptToExtendSessionTimeoutId =
window.setTimeout(promptToExtendSession, secondsBeforePrompt * 1000);
};
// Public Functions
return {
start: function () {
startSessionManager();
},
extend: function () {
refreshSession();
}
};
} ();
SessionManager.start();
});
Remove the var prefix from SessionManager.
