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/weex_logo_blue@3x.png"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 || typeofmsg !== 'string') { msg = 'I am Toast show!'; } duration =duration || 2; this.$call('modal', 'toast', { 'message': msg, 'duration': duration }); }, alert: function(msg, okTitle, cancelTitle) { varself = this; if(!msg || typeofmsg !== 'string') { msg = "I am Alert!"; } this.$call('modal', 'alert', { 'message': msg, 'okTitle': okTitle, 'cancelTitle': cancelTitle }, function() { self.toast("Click Alert OK Bnt!!"); }); }, confirm: function(msg, okTitle, cancelTitle) { varself = this if(!msg || typeofmsg !== 'string') { msg = "I am Confirm!"; } okTitle =okTitle || "OK"; cancelTitle =cancelTitle || "Cancel"; this.$call('modal', 'confirm', { 'message': msg, 'okTitle': okTitle, 'cancelTitle': cancelTitle }, function(result) { self.toast("Click Confirm " +result); }); }, prompt: function() { varself = this; this.$call('modal', 'prompt', { 'message': 'I am Prompt!', 'okTitle': 'ok', 'cancelTitle': 'cancel'}, function(result) { self.toast("Click Prompt " +result); }); } } } </script> <style> </style>
