Weex 初始

1.一旦数据和模板绑定，数据的变化会立即体现在前台的变化

<template>
  <container>
    <text style="font-size: {{size}}">{{title}}</text>
  </container>
</template>

<script>
  module.exports = {
    data: {
      size: 48,
      title: 'Alibaba Weex Team'
    }
  }
</script>

<template>
  <container>
    <text style="font-size: {{title.size}}">{{title.value}}</text>
  </container>
</template>

<script>
  module.exports = {
    data: {
      title: {
        size: 48,
        value: 'Alibaba Weex Team'
      }
    }
  }
</script>

2.样式类

<template>
  <container>
    <text style="font-size: {{fontSize}};">Alibaba</text>
    <text class="large {{textClass}}">Weex Team</text>
  </container>
</template>
<style>
  .large {font-size: 32;}
  .highlight {color: #ff0000;}
</style>
<script>
  module.exports = {
    data: {
      fontSize: 32,
      textClass: 'highlight'
    }
  }
</script>

3.事件

<template>
  <container>
    <text onclick="toggle">Toggle</text>
    <image  class="thumb" src="http://alibaba.github.io/weex/img/[e-mail]" if="{{shown}}"></image>
  </container>
</template>

<script>
  module.exports = {
    data: {
      shown: true
    },
    methods: {
      toggle: function () {
        this.shown = !this.shown
      }
    }
  }
</script>

<style>
  .thumb { width: 100; height: 100; }
</style>

<template>
  <scroller>
    <wxc-panel title="Toast" type="primary">
      <wxc-button type="primary" onclick="{{toast}}" value="Toast"></wxc-button>
    </wxc-panel>

    <wxc-panel title="Dialog" type="primary">
      <wxc-button type="success" onclick="{{alert}}" value="Alert" style="margin-bottom: 20px;"></wxc-button>
      <wxc-button type="primary" onclick="{{confirm}}" value="Confirm" style="margin-bottom: 20px;"></wxc-button>
      <wxc-button type="warning" onclick="{{prompt}}" value="Prompt"></wxc-button>
    </wxc-panel>
  </scroller>
</template>

<script>
  require('weex-components');
  module.exports = {
    data: {},
    methods: {
      toast: function(msg, duration) {
        if (!msg || typeof msg !== 'string') {
          msg = 'I am Toast show!';
        }

        duration = duration || 2;
        this.$call('modal', 'toast', {
          'message': msg,
          'duration': duration
        });
      },
      alert: function(msg, okTitle, cancelTitle) {
        var self = this;
        if (!msg || typeof msg !== 'string') {
          msg = "I am Alert!";
        }
        this.$call('modal', 'alert', {
          'message': msg,
          'okTitle': okTitle,
          'cancelTitle': cancelTitle
        }, function() {
          self.toast("Click Alert OK Bnt!!");
        });
      },
      confirm: function(msg, okTitle, cancelTitle) {
        var self = this
        if (!msg || typeof msg !== 'string') {
          msg = "I am Confirm!";
        }

        okTitle = okTitle || "OK";
        cancelTitle = cancelTitle || "Cancel";
        this.$call('modal', 'confirm', {
          'message': msg,
          'okTitle': okTitle,
          'cancelTitle': cancelTitle
        }, function(result) {
          self.toast("Click Confirm  " + result);
        });
      },
      prompt: function() {
        var self = this;
        this.$call('modal', 'prompt', {
          'message': 'I am Prompt!',
          'okTitle': 'ok',
          'cancelTitle': 'cancel'
        }, function(result) {
          self.toast("Click Prompt  " + result);
        });
      }
    }
  }
</script>
