jQuery Animation Using Relative Values & Predefined Values
jQuery Animation With Relative Values
This method can also define relative values (the value is close to the element's current value). This is accomplished by appending += or -=
to the value:
$("button").click(function(){
$("div").animate({
left: '250px',
height: '+=150px',
width: '+=150px'
});
});
jQuery Animation With Predefined Values
You can even specify the animation value for a property as "display,"
"hide," or "toggle"
:
$("button").click(function(){
$("div").animate({
height: 'toggle'
});
});
