jQuery animate() Metode

Voorbeeld

"Animeer" 'n element deur sy hoogte te verander:

$("button").click(function(){
$("#box").animate({height: "300px"});
});

Definisie en gebruik

Die animate()-metode voer 'n pasgemaakte animasie van 'n stel CSS-eienskappe uit.

Hierdie metode verander 'n element van een toestand na 'n ander met CSS-style. Die CSS-eienskapwaarde word geleidelik verander om 'n geanimeerde effek te skep.

Slegs numeriese waardes kan geanimeer word (soos "margin:30px"). Stringwaardes kan nie geanimeer word nie (soos "agtergrondkleur:rooi"), behalwe vir die stringe "wys", "versteek" en "wissel". Hierdie waardes laat toe om die geanimeerde element weg te steek en te wys.

Wenk: Gebruik "+=" of "-=" vir relatiewe animasies.

Sintaksis

(selector).animate({styles},speed,easing,callback)

Parameter	Description
styles	Required. Specifies one or more CSS properties/values to animate. Note: The property names must be camel-cased when used with the animate() method: You will need to write paddingLeft instead of padding-left, marginRight instead of margin-right, and so on. Properties that can be animated: Only numeric values can be animated (like "margin:30px"). String values cannot be animated (like "background-color:red"), except for the strings "show", "hide" and "toggle". These values allow hiding and showing the animated element.
speed	Optional. Specifies the speed of the animation. Default value is 400 milliseconds Possible values: milliseconds (like 100, 1000, 5000, etc) "slow" "fast"
easing	Optional. Specifies the speed of the element in different points of the animation. Default value is "swing". Possible values: "swing" - moves slower at the beginning/end, but faster in the middle "linear" - moves in a constant speed Tip: More easing functions are available in external plugins.
callback	Optional. A function to be executed after the animation completes. To learn more about callback, please read our jQuery Callback chapter
