我正在使用它来更改创建js的填充颜色,这不起作用
var shape_rect = new createjs.Shape();
shape_rect.graphics.beginFill("#FFD64B").drawRect(61, 253, 398, 25);
shap_rect3.addEventListener('mouseover', function (evt) {
shap_rect3.graphics.beginFill("#FFD64B").drawRect(61, 253, 398, 25);
stage.update();
});
解决方法:
这里只有几件事：
首先,我注意到eventListener已链接到shap_rect3,但尚未定义(至少在您的示例中未定义).鼠标悬停的颜色也与声明的颜色相同,因此您不会看到任何更改.
假设shap_rect3是一个错字,这应该对您有用.
loadGame = function() {
var canvas = document.getElementById('canvas');
var stage = new createjs.Stage(canvas);
stage.enableMouseOver(); //Enable MouseOver events
var shape_rect = new createjs.Shape(); //Create your shape variable
shape_rect.graphics.beginFill("#FFD64B").drawRect(61, 253, 398, 25); //Draw initial rectangle
shape_rect.on('mouseover', function(evt) { //Change colour on mouseOver
shape_rect.graphics.beginFill("#FF5400").drawRect(61, 253, 398, 25);
stage.update(evt);
});
//Add this if you want to simulate a hover state and return the rectangle back to it's original colour
shape_rect.on('mouseout', function(evt) { //.on gives the same result as .addEventListener (at least from a visual perspective, I'm not sure about resource usage)
shape_rect.graphics.beginFill("#FFD64B").drawRect(61, 253, 398, 25);
stage.update(evt);
});
stage.addChild(shape_rect);
stage.update();
}
我是createJS和easylJS的新手,但这是实现此目的的一种方法.然后只需运行loadGame函数onLoad：
