jQuery fast review

Here I have provided some jQuery properties which will give you overview & to quick learn.

While writing jQuery we need to remember two things i.e  
      #"Find element" .. and
      #"do something to it"..
Find element : find a element by selector..
i.e. $("")  --- selector
jQuery selectors are used to "find" (or select) HTML elements based on their id, classes, types, attributes, values of attributes.

You can select a element by using 
    "element id" using "#"                     -- eg: $("#divid")
    "class attribute" using "." (dot)        -- eg: $(".classname")
    "element tag"  using tag name         -- eg: $("table"), $("div"),..

Examples:
$("#contentid")  -- get element with id "contentid" .
$("li:first")          -- get first list item.
$("tr:odd")         -- get odd numbered table rows
$(this).hide()      -- hides the current element.
$("p").hide()      -- hides all <p> elements.
$(".test").hide()  -- hides all elements with class="test".
$("#test").hide() -- hides the element with id="test".

Properties :
Here are some of properties which are most using..

Hide all div's with jQuery :
$("div").hide( );

You can also find element by string selectors together
$("#myid, .myclass, table")

Add Class:
$("div").addclass("myclass");
here selector find element div and add class attribute "myclass" to it.

Float div position to top when you scroll

In the below code I have explained about Maintaining div tag at top of the screen when scrolling..

IF my current position is greater or equal to the “sticker” position, give the sticker div a class of “stick”.  This changes the CSS of the div to have a FIXED position as long as the viewport is lower than the position of the sticker.

HTML - Take a div tag which contain the data which you want to float.

<div id="sticker">
    ...start scrolling..
   //Add your Code block here...
</div>

CSS 
Styles applied to div#sticker and the class “.stick
"stick" class is most important, which maintain position when you scroll.

div#sticker {
    padding:20px;
    margin:20px 0;
    background:#AAA;
    width:190px;
}
.stick {
    position:fixed;
    top:0px;

}


jQuery – Calculates the position of the sticker div and makes its position fixed if the page has scrolled that far

$(document).ready(function() {
    var s = $("#sticker");
    var pos = s.position();                    
    $(window).scroll(function() {
        var windowpos = $(window).scrollTop();
        s.html("Distance from top:" + pos.top + "<br />Scroll position: " + windowpos);
        if (windowpos >= pos.top) {
            s.addClass("stick");
        } else {
            s.removeClass("stick"); 
        }

    });
