如何在框架中使用vue和vux组件

要在light框架中使用vue组件，首先需要在命令行安装vue插件light plugin -a vue,page 页面中需要引用js 文件vue-components.js（启用时用light release -wb -e vue）。

<!DOCTYPE html>
<html>
<head>
  <snippet id="header" />
  <!-- build:css css/index.css -->
  <link rel="stylesheet" href="css/style.css" />
  <!--<link rel="stylesheet" href="css/index.css" />-->
  <!-- endbuild -->
  <title>lightProjectDemo-Just For Fun</title>
</head>
<body>
  <div id="main">
    <view id="lightProjectDemo" home="true" />
  </div>
  <snippet id="footer" />
  <script type="text/javascript" src="//res.lightyy.com/lighting/framework/light-2.2.min.js"></script>
  <script type="text/javascript" src="config.js"></script>
  <!-- build:js js/index.js -->
  <script src="vue-components.js"></script>
  <!--<script type="text/javascript" src="js/lib/underscore.js"></script>-->
  <!-- inject:view -->
  <!-- endinject -->
  <!-- endbuild -->
  <script type="text/javascript">
    Light.start();
  </script>
</body>
</html>

做好这些准备工作后，我们就可以使用vue组件了，假如我们现在需要做一个头部的组件head.vue,步骤如下：

1.在目录结构的vue文件夹中新建一个vue文件命名为head.vue


<template>
    <div class="headFixed">
        <h2 class="tab">
            <span @click="back()" class="back">返回</span>
            <em class="view">{{title}}</em>
        </h2>
    </div>
</template>
<style>
</style>
<script>
    export default {
        props:['title'],
        methods:{
            back:function () {
                history.back();
            }
        }
    }
</script>

2.调用

在视图中的调用方法如下：


<div id="lightProjectDemo" style="display:none;">
    <vue-head :title.sync="title"></vue-head>
</div>

这样一个vue组件就调用成功了，title的值可以在视图的js文件中根据需要设置。


;(function(){
  App.defineViewModel("#lightProjectDemo",{
       data:{
           title:"首页"
       },
       watch:{},
       methods:{}
     },{
     ready:function(){
     },
     beforeRender:function (params) {
     },
     afterRender:function (params){
     },
     beforeUnRender:function (){
     },
     afterUnRender:function (){
     }
  });
})();

vux组件 的使用方法同上，假如我们现在需要使用vux组件中的五星评价功能，先新建一个vue文件命名为star.vue，然后把vux的对应的代码拿过来


<template>
  <div class="vux-rater">
    <input v-model="currentValue" style="display:none">
    <a class="vux-rater-box" v-for="i in max" @click="handleClick(i-1)" :class="{'is-active':currentValue > i-1}" :style="{color: colors && colors[i-1] ? colors[i-1] : '#ccc',marginRight:margin+'px',fontSize: fontSize + 'px', width: fontSize + 'px', height: fontSize + 'px', lineHeight: fontSize + 'px'}">
      <span class="vux-rater-inner">{{star}}<span class="vux-rater-outer" :style="{color: activeColor, width: cutPercent + '%'}" v-if="cutPercent > 0 && cutIndex === i-1">{{star}}</span></span>
    </a>
  </div>
</template>
<script>
export default {
  created () {
    this.currentValue = this.value
  },
  mounted () {
    this.updateStyle()
  },
  props: {
    max: {
      type: Number,
      default: 5
    },
    value: {
      type: Number,
      default: 0
    },
    disabled: Boolean,
    star: {
      type: String,
      default: '★'
    },
    activeColor: {
      type: String,
      default: '#fc6'
    },
    margin: {
      type: Number,
      default: 2
    },
    fontSize: {
      type: Number,
      default: 25
    }
  },
  computed: {
    sliceValue () {
      const _val = this.currentValue.toString().split('.')
      return _val.length === 1 ? [_val[0], 0] : _val
    },
    cutIndex () {
      return this.sliceValue[0] * 1
    },
    cutPercent () {
      return this.sliceValue[1] * 10
    }
  },
  methods: {
    handleClick (i, force) {
      if (!this.disabled || force) {
        if (this.currentValue === i + 1) {
          this.currentValue = i
          this.updateStyle()
        } else {
          this.currentValue = i + 1
        }
      }
    },
    updateStyle () {
      for (var j = 0; j < this.max; j++) {
        if (j <= this.currentValue - 1) {
          this.$set(this.colors, j, this.activeColor)
        } else {
          this.$set(this.colors, j, '#ccc')
        }
      }
    }
  },
  data () {
    return {
      colors: [],
      currentValue: 0
    }
  },
  watch: {
    currentValue (val) {
      this.updateStyle()
      this.$emit('input', val)
    },
    value (val) {
      this.currentValue = val
    }
  }
}
</script>
<style>
.vux-rater {
  text-align: left;
  display: inline-block;
  line-height: normal;
}
.vux-rater a {
  display: inline-block;
  text-align: center;
  cursor: pointer;
  color: #ccc;
}
.vux-rater a:last-child {
  padding-right: 2px!important;
  margin-right: 0px!important;
}
.vux-rater a:hover {
  color: #ffdd99;
}
.vux-rater a.is-disabled {
  color: #ccc !important;
  cursor: not-allowed;
}
.vux-rater-box {
  position: relative;
}
.vux-rater-inner {
  position: relative;
  display: inline-block;
}
.vux-rater-outer {
  position: absolute;
  left: 0;
  top: 0;
  display: inline-block;
  overflow: hidden;
}
</style>

最后在视图中调用即可


<div id="lightProjectDemo" style="display:none;">
    <vue-head :title.sync="title"></vue-head>
    <vue-star></vue-star>
</div>
