今天完成的事情:
学习滚轮事件
学习拖拽
window.onload = function () {
/*
拖拽box1元素
流程1.当鼠标在被拖拽元素上按下时,开始拖拽onmousemove
2.当鼠标移动时被拖拽元素跟随鼠标移动onmousemove
3.当鼠标松开时,被拖拽元素固定在当前位置onmousemove
*/
//
var box1 = document.getElementById("box1");
// 为box1绑定一个鼠标按下事件
box1.onmousemove = function () {
alert("鼠标按下,开始拖延~~")
// 为document
document.onmousemove = function (event) {
event = event || window.event;
// 获取鼠标的坐标
var left = event.clientX;
var top = event.clientY;
}
};
};
window.onload = function () {
