This page is a landing point for demonstrating complex animations of DOM nodes built on uses of the chain and combine functions to perform complex animations with a single call to ‘play().
Examples¶
Example 1: Demonstration of combining three chained animations¶
This animation changes position, size, opacity, and color in a single, combined, animation
<script>
dojo.require("dijit.form.Button");
dojo.require("dojo.fx");
dojo.require("dojo.fx.easing");
function basicCombine(){
//Function linked to the button to trigger the effects.
function combineIt() {
//Fade the node out, then in
var displayAnim = dojo.fx.chain([
dojo.fadeOut({node: "basicNode1", duration: 1000}),
dojo.fadeIn({node: "basicNode1", duration: 1000})
]);
//Move the node while it's fading out and in.
var moveAnim = dojo.fx.chain([
dojo.animateProperty({node: "basicNode1",
properties: {
marginLeft: {start: 0, end: 400, unit: "px"}
},
duration: 1000,
easing: dojo.fx.easing.backOut
}),
dojo.animateProperty({node: "basicNode1",
properties: {
marginLeft: {start: 400, end: 0, unit: "px"}
},
duration: 1000,
easing: dojo.fx.easing.backOut
})
]);
//Resize and change color of the node as it moves too.
var resizeColorAnim = dojo.fx.chain([
dojo.animateProperty({node: "basicNode1",
properties: {
width: {start: 100, end: 200, unit: "px"},
height: {start: 100, end: 200, unit: "px"},
backgroundColor: {start: "red", end: "green"}
},
duration: 1000
}),
dojo.animateProperty({node: "basicNode1",
properties: {
width: {start: 200, end: 100, unit: "px"},
height: {start: 200, end: 100, unit: "px"},
backgroundColor: {start: "green", end: "red"}
},
duration: 1000
})
]);
//Combine the three sets of animations into one that runs in parallel.
var combinedAnim = dojo.fx.combine([displayAnim, moveAnim, resizeColorAnim]);
//Set it so that every time it ends, it runs again. (And connect the stop action to it!)
var handle = dojo.connect(combinedAnim, "onEnd", function(){combineIt();});
dojo.connect(dijit.byId("endButton"), "onClick", function(){dojo.disconnect(handle);});
//Run it!
combinedAnim.play();
}
dojo.connect(dijit.byId("startButton"), "onClick", combineIt);
}
dojo.addOnLoad(basicCombine);
