How does jQuery implement hide() and show()

By display: none
Not visibility: hidden


JQuery Source code:

hide: function( speed, easing, callback ) {
if ( speed || speed === 0 ) {
return this.animate( genFx("hide", 3), speed, easing, callback);

} else {
for ( var i = 0, j = this.length; i < j; i++ ) {
var display = jQuery.css( this[i], "display" );

if ( display !== "none" ) {
jQuery.data( this[i], "olddisplay", display );
}
}

// Set the display of the elements in a second loop
// to avoid the constant reflow
for ( i = 0; i < j; i++ ) {
this[i].style.display = "none";
}

return this;
}
}

Three ways for initialization tasks in Javascript: $(handler), Onload() and pageLoad()

1. pageLoad(), it is called for every partial postback. We should put JQuery event handlers in this function.

2. window.onload = function () {alert("onload");}

Onload() event will be called only after the DOM and associated resources like images got loaded


3. JQuery $(document).ready(handler)
jQuery's document.ready() event will be called once the DOM is loaded, it wont wait for the resources like images to get loaded

All three of the following syntaxes are equivalent:

• $(document).ready(handler)
• $().ready(handler) (this is not recommended)
• $(handler)
