宣传页项目开发（二）

由 一个人想着一个人 提交于 2020-02-10 15:16:24

之前已经完成了静态页面的开发，接下来是网页动态效果制作

css实现动画的两种方式：

1、transition: all 1s;

2、animation: move 1s infinite ease-in-out .5s;

@keyframes move{

0%{ transform: rotate(0deg); }

40%{ transform: rotate(45deg); }

100%{ transform: rotate(0deg); }

}

两种遍历的方式，遍历对象 { }  遍历数组 [ ]

for(k in obj){

do (k);

}

for(var i=0; i<obj.length; i++){

do( obj[i] );

}

css动画测试

首先新建一个animate.css专门用于存放动画效果

.screen-1-heading{ transition:all 1s; }
.screen-1-heading-init{ opacity: 0;transform:translate(0,100%); }
.screen-1-heading-done{ opacity: 1;transform:translate(0,0); }
/*# sourceMappingURL=animate.css.map */

 

新建一个动画测试脚本 test.js

// 需要设置动画的元素
var animateElements={
    ".screen-1":[
        ".screen-1-heading",
        ".screen-1-phone",
        ".screen-1-shadow"
    ]
}

//设置动画
function setAnimate(screenName){//屏的类名，如： ".screen-1"
    var screen=document.querySelector(screenName);//获取哪一屏
    var screenEles=animateElements[screenName];//获取该屏下要动画的所有元素
    var isInit=false; //动画是否初始化
    var isDone=false;//动画是否完成

    screen.onclick=function(){
        //初始化
        if(isInit===false){
            for(var i=0,len=screenEles.length;i<len;i++){
                var newCls=screenEles[i].substr(1)+"-init";
                var screenEle=document.querySelector(screenEles[i]);//某个要动画的元素
                var baseCls=screenEle.getAttribute("class");//获取原来的类
                screenEle.setAttribute("class", baseCls+" "+newCls);//添加init类
            }
            isInit=true;
            return;
        }

        //完成动画
        if(isDone===false){
            for(var i=0,len=screenEles.length;i<len;i++){            
                var screenEle=document.querySelector(screenEles[i]);//某个要动画的元素
                var baseCls=screenEle.getAttribute("class");//获取原来的类
                var newCls=screenEles[i].replace("-init", "-done").substr(1);
                screenEle.setAttribute("class", newCls);//添加init类
            }
            isDone=true;
            return;
        }

        //切换done到init
        if(isDone===true){
            for(var i=0,len=screenEles.length;i<len;i++){            
                var screenEle=document.querySelector(screenEles[i]);//某个要动画的元素
                var baseCls=screenEle.getAttribute("class");//获取原来的类
                var newCls=screenEles[i].replace("-done", "-init").substr(1);
                screenEle.setAttribute("class", newCls);//添加init类
            }
            isDone=false;
            return;
        }
    }

}

setAnimate(".screen-1");

补充：给容器设置overflow: hidden;   

可以保证元素在进行动画的过程中，不会占用别的屏的空间

div 可以添加hover伪类制作动画，但是为了更好的兼容性，建议外面加上a标签，display设置为block，来添加hover 效果
