mouseover with delay (using hoverIntent plugin)

hoverIntent is a plug-in that attempts to determine the user’s intent… like a crystal ball, only with mouse movement! It works like (and was derived from) jQuery’s built-in hover. However, instead of immediately calling the onMouseOver function, it waits until the user’s mouse slows down enough before making the call.

Trigger Google conversion on some event

Normally Google conversion code is added in header or footer of the “Thank you for your purchase” pages. A conversion is logged when someone lands on such thank you pages.

Post to your Facebook wall using Javascript SDK

Step1:

<div id="fb_div">
    <h3>Post to your Facebook wall:</h3> <br />
    <textarea id="fb_message" name="fb_message" cols="70" rows="7"></textarea> <br />
    <input type="button" value="Post on Wall" onClick="post_on_wall();" />
</div>

Step 2:

window.fbAsyncInit = function()
{
    FB.init({
        appId  : 'xxxxxxxxxxxxxxx',
        status : true, // check login status
        cookie : true, // enable cookies to allow the server to access the session
        xfbml  : true , // parse XFBML
        oauth : true // Enable oauth authentication
    });


};

function post_on_wall()
{
    FB.login(function(response)
    {
        if (response.authResponse)
        {
            alert('Logged in!');

            // Post message to your wall

            var opts = {
                message : document.getElementById('fb_message').value,
                name : 'Post Title',
                link : 'www.postlink.com',
                description : 'post description',
                picture : 'http://2.gravatar.com/avatar/8a13ef9d2ad87de23c6962b216f8e9f4?s=128&d=mm&r=G'
            };

            FB.api('/me/feed', 'post', opts, function(response)
            {
                if (!response || response.error)
                {
                    alert('Posting error occured');
                }
                else
                {
                    alert('Success - Post ID: ' + response.id);
                }
            });
        }
        else
        {
            alert('Not logged in');
        }
    }, { scope : 'publish_stream' });
}

Step3:
create a div with id=”fb-root” and paste below code after this div

<div id="fb-root"></div>

Step4:

(function() {
    var e = document.createElement('script');
    // replacing with an older version until FB fixes the cancel-login bug
    e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
    //e.src = 'scripts/all.js';
    e.async = true;
    document.getElementById('fb-root').appendChild(e);
}());

keyup function with delay

 

This code will execute a function after the user has stopped typing for a time of 1000ms. Hence the function will not be called on each keyup event. Great!!!

jQuery(function(){
    var delay = (function(){
        var timer = 0;
        return function(callback, ms){
            clearTimeout (timer);
            timer = setTimeout(callback, ms);
        };
    })();

    $('input').keyup(function() {
        delay(function(){
            alert('Time elapsed!');
        }, 1000 );
    });

});

jQuery UI Multiselect by Michael

First off, you can visit the demo to see the widget in action.

The script depends on jQuery 1.3 and jQuery UI 1.7 and is style-able using Themeroller. It works in an unobtrusive fashion, by just turning html multiple select inputs into a sexier equivalent. There’s no extra markup needed.
