vue-fullpage应用

1.vue-fullpage 是一个挺好用的全屏插件

git地址https://github.com/wendaosanshou/vue-fullpage

2.用法：npm 安装

npm install vue-fullpage --save
npm install animate.css --save

3.在main.js 中引入

import 'animate.css'
import 'vue-fullpage/vue-fullpage.css'
import VueFullpage from 'vue-fullpage'
Vue.use(VueFullpage)

4. app.vue template

<div class="fullpage-container">
  <div class="fullpage-wp" v-fullpage="opts">
    <div class="page-1 page">
      <p class="part-1" v-animate="{value: 'bounceInLeft'}">vue-fullpage</p>
    </div>
    <div class="page-2 page">
      <p class="part-2" v-animate="{value: 'bounceInRight'}">vue-fullpage</p>
    </div>
    <div class="page-3 page">
      <p class="part-3" v-animate="{value: 'bounceInLeft', delay: 0}">vue-fullpage</p>
      <p class="part-3" v-animate="{value: 'bounceInRight', delay: 600}">vue-fullpage</p>
      <p class="part-3" v-animate="{value: 'zoomInDown', delay: 1200}">vue-fullpage</p>
    </div>
  </div>
</div>
5.script
export default {
  data() {
    return {
      opts: {
        start: 0,
        dir: 'v',
        duration: 500,
        beforeChange: function (prev, next) {
        },
        afterChange: function (prev, next) {
        }
      }
    }
  }
}
6.css 父级一定是充满全屏才可以 可以用定位来写
<style>
.page-container {
  position: absolute;
  left: 0;
  top: 0;
   100%;
  height: 100%;
}
</style>

9，这个插件有一个bug 页面加入点击事件就会始终回到第一页，git里面给出了解决的方案。
可以将安装的依赖里面的js进行替换解决。

将下面的js 在新的文件夹里 新建一个 在main.js 中引入
index.js
'use strict';

var fullpage = {};
var opt = {
start: 0,
duration: 500,
loop: false,
dir: 'v',
der: 0.1,
movingFlag: false,
preventWechat: false,
needInitAfterUpdated: false,
beforeChange: function(data) {},
afterChange: function(data) {}
};

fullpage.install = function(Vue, options) {
var that = fullpage;
Vue.directive('fullpage', {
inserted: function(el, binding, vnode) {
var opts = binding.value || {};
that.init(el, opts, vnode);
},
componentUpdated: function(el, binding, vnode) {
if (!that.o.needInitAfterUpdated) {
return;
}
var opts = binding.value || {};
that.init(el, opts, vnode);
}
});

Vue.directive('animate', {
inserted: function(el, binding, vnode) {
if (binding.value) {
that.initAnimate(el, binding, vnode);
}
}
});
};

fullpage.initAnimate = function(el, binding, vnode) {
var that = fullpage;
var vm = vnode.context;
var aminate = binding.value;
el.style.opacity = '0';
vm.$on('toogle_animate', function(curIndex) {
var parent = el.parentNode;
while (parent.getAttribute('data-id') === null) {
parent = parent.parentNode;
}
var curPage = +parent.getAttribute('data-id');
if (curIndex === curPage) {
that.addAnimated(el, aminate);
} else {
el.style.opacity = '0';
that.removeAnimated(el, aminate);
}
});
};

fullpage.addAnimated = function(el, animate) {
var delay = animate.delay || 0;
el.classList.add('animated');
window.setTimeout(function() {
el.style.opacity = '1';
el.classList.add(animate.value);
}, delay);
};

fullpage.removeAnimated = function(el, animate) {
var classes = el.getAttribute('class');
if (classes && classes.indexOf('animated') > -1) {
el.classList.remove(animate.value);
}
};

fullpage.assignOpts = function(option) {
var that = fullpage;
var o = option || {};
for (var key in opt) {
if (!o.hasOwnProperty(key)) {
o[key] = opt[key];
}
}
that.o = o;
};

fullpage.initScrollDirection = function() {
if (this.o.dir !== 'v') {
this.el.classList.add('fullpage-wp-h');
}
};

fullpage.init = function(el, options, vnode) {
var that = fullpage;
that.assignOpts(options);

that.vm = vnode.context;
that.vm.$fullpage = that;
that.curIndex = that.o.start;

that.startY = 0;
that.o.movingFlag = false;

that.el = el;
that.el.classList.add('fullpage-wp');

that.parentEle = that.el.parentNode;
that.parentEle.classList.add('fullpage-container');

that.pageEles = that.el.children;
that.total = that.pageEles.length;

that.initScrollDirection();
window.setTimeout(function() {
that.width = that.parentEle.offsetWidth;
that.height = that.parentEle.offsetHeight;

for (var i = 0; i < that.pageEles.length; i++) {
var pageEle = that.pageEles[i];
pageEle.setAttribute('data-id', i);
pageEle.classList.add('page');
pageEle.style.width = that.width + 'px';
pageEle.style.height = that.height + 'px';
that.initEvent(pageEle);
}
that.moveTo(that.curIndex, false);
}, 0);
};

fullpage.initEvent = function(el) {
var that = fullpage;
that.prevIndex = that.curIndex;
el.addEventListener('touchstart', function(e) {
if (that.o.movingFlag) {
return false;
}
that.startX = e.targetTouches[0].pageX;
that.startY = e.targetTouches[0].pageY;
});
el.addEventListener('touchend', function(e) {
if (that.o.movingFlag) {
return false;
}
var dir = that.o.dir;
var sub =
dir === 'v'
? (e.changedTouches[0].pageY - that.startY) / that.height
: (e.changedTouches[0].pageX - that.startX) / that.width;
var der = sub > that.o.der ? -1 : sub < -that.o.der ? 1 : 0;
// that.curIndex推迟到moveTo执行完之后再更新
var nextIndex = that.curIndex + der;

if (nextIndex >= 0 && nextIndex < that.total) {
that.moveTo(nextIndex, true);
} else {
if (that.o.loop) {
nextIndex = nextIndex < 0 ? that.total - 1 : 0;
that.moveTo(nextIndex, true);
} else {
that.curIndex = nextIndex < 0 ? 0 : that.total - 1;
}
}
});
if (that.o.preventWechat) {
el.addEventListener('touchmove', function(e) {
e.preventDefault();
});
}
};

fullpage.moveTo = function(curIndex, anim) {
var that = fullpage;
var dist =
that.o.dir === 'v' ? curIndex * -that.height : curIndex * -that.width;
that.o.movingFlag = true;
var flag = that.o.beforeChange(that.prevIndex, curIndex);
if (flag === false) {
// 重置movingFlag
that.o.movingFlag = false;
return false;
}
that.curIndex = curIndex;

if (anim) {
that.el.classList.add('anim');
} else {
that.el.classList.remove('anim');
}

that.move(dist);
window.setTimeout(function() {
that.o.afterChange(that.prevIndex, curIndex);
that.o.movingFlag = false;
that.prevIndex = curIndex;
that.vm.$emit('toogle_animate', curIndex);
}, that.o.duration);
};

fullpage.move = function(dist) {
var xPx = '0px';
var yPx = '0px';
if (this.o.dir === 'v') {
yPx = dist + 'px';
} else {
xPx = dist + 'px';
}
this.el.style.cssText +=
'-webkit-transform:translate3d(' +
xPx +
', ' +
yPx +
', 0px);transform:translate3d(' +
xPx +
', ' +
yPx +
', 0px);';
};

if (window.Vue) {
window.VueFullpage = fullpage;
Vue.use(fullpage);
}

export default fullpage;
 
 
10.修改后的main.js
 

其他的都没个改变，这样解决了那个点击事件始终回到第一页的问题。
