微信小程序~基础组件

可移动的视图容器，在页面中可以拖拽滑动。movable-view必须在 movable-area 组件中，并且必须是直接子节点，否则不能移动。

bindchange 返回的 source 表示产生移动的原因

Bug & Tip

1. tip: movable-view 必须设置width和height属性，不设置默认为10px
2. tip: movable-view 默认为绝对定位，top和left属性为0px

<view class="section">
<view class="section__title">movable-view区域小于movable-area</view>

normal: 正常无变化(默认处理方式.文本自动处理换行.假如抵达容器边界内容会转到下一行)
pre: 保持HTML源代码的空格与换行,等同与pre标签
nowrap: 强制文本在一行,除非遇到br换行标签
pre-wrap: 同pre属性,但是遇到超出容器范围的时候会自动换行
pre-line: 同pre属性,但是遇到连续空格会被看作一个空格
inherit: 继承
