本篇文章将介绍小程序的基础组件——表单组件。

表单组件分为11个组件:

• button
• checkbox
• form
• input
• label
• picker——普通选择器，时间选择器，日期选择器，默认是普通选择器
• picker-view——嵌入页面的滚动选择器
• radio
• slider——滑动选择器
• switch
• textarea

由于表单提交的组件和很多语言的表单提交方式大同小异，本文不作详细介绍，只写一些简单代码，仅供参考。详细的API可以参考。https://mp.weixin.qq.com/debug/wxadoc/dev/component/button.html

button

/** wxss **/
/** 修改button默认的点击态样式类**/
.button-hover {
  background-color: red;
}
/** 添加自定义button点击态样式类**/
.other-button-hover {
  background-color: blue;
}
<button type="default" size="{{defaultSize}}" loading="{{loading}}" plain="{{plain}}"
        disabled="{{disabled}}" bindtap="default" hover-class="other-button-hover"> default </button>
<button type="primary" size="{{primarySize}}" loading="{{loading}}" plain="{{plain}}"
        disabled="{{disabled}}" bindtap="primary"> primary </button>
<button type="warn" size="{{warnSize}}" loading="{{loading}}" plain="{{plain}}"
        disabled="{{disabled}}" bindtap="warn"> warn </button>
<button bindtap="setDisabled">点击设置以上按钮disabled属性</button>
<button bindtap="setPlain">点击设置以上按钮plain属性</button>
<button bindtap="setLoading">点击设置以上按钮loading属性</button>
Page({
  data: {
    defaultSize: 'default',
    primarySize: 'default',
    warnSize: 'default',
    disabled: false,
    plain: false,
    loading: false
  },
  setDisabled: function(e) {
    this.setData({
      disabled: !this.data.disabled
    })
  },
  setPlain: function(e) {
    this.setData({
      plain: !this.data.plain
    })
  },
  setLoading: function(e) {
    this.setData({
      loading: !this.data.loading
    })
  }
})
