微信小程序 tips组件封装

不是原创，是自己作为学习，iview-weapp封装小程序组件。

一，组件的样式：

 像这样的提示框。

二，组件的引用

{
  "usingComponents": {
    "i-alert": "../../dist/alert/index"
  }
}

<i-alert>
    An info prompt
</i-alert>

<i-alert type="success">
    An success prompt
</i-alert>


<i-alert type="warning">
    An success prompt
</i-alert>


<i-alert type="error" show-icon>
    An error prompt
</i-alert>


<i-alert type="error" show-icon desc>
    An error prompt
    <view slot="desc">Content of prompt. Content of prompt.</view>
</i-alert>


<i-alert type="success" show-icon desc closable bind:close="handleClick">
    An success prompt
    <view slot="desc">Content of prompt. Content of prompt.</view>
</i-alert>

三，组件代码

1,组件的json

{
    "component": true,
    "usingComponents":
    {
        "i-icon": "../icon/index"
    }
}

2，组件HTML

<view class="i-class i-alert {{'i-alert-'+type}} {{showIcon?'i-alert-with-icon':''}} {{desc?'i-alert-with-desc':''}}" wx:if="{{!closed}}">
    <view wx:if="{{ showIcon }}" class="i-alert-icon">
        <i-icon type="prompt" wx:if="{{ type === 'info' }}" size="{{desc?24:16}}"></i-icon>
        <i-icon type="success" wx:if="{{ type === 'success' }}" size="{{desc?24:16}}"></i-icon>
        <i-icon type="warning" wx:if="{{ type === 'warning' }}" size="{{desc?24:16}}"></i-icon>
        <i-icon type="delete" wx:if="{{ type === 'error' }}" size="{{desc?24:16}}"></i-icon>
    </view>
    <slot></slot>
    <view class="i-alert-desc">
        <slot name="desc"></slot>
    </view>
    <view class="i-alert-close" wx:if="{{ closable }}" bindtap="handleTap">
        <i-icon type="close"></i-icon>
    </view>
</view>

3,组件的JS

Component({
    externalClasses: ['i-class'],
    options: {
        multipleSlots: true
    },
    properties: {
        //info, success, warning, error
        type: {
            type: String,
            value: 'info'
        },
        closable: {
            type: Boolean,
            value: false
        },
        showIcon: {
            type: Boolean,
            default: false
        },
        desc: {
            type: Boolean,
            default: false
        },
    },
    data: {
        closed: false
    },
    methods: {
        handleTap() {
            this.setData({
                closed: !this.data.closed,
            });
            this.triggerEvent('close');
        },

    }
});

4,组件的css

    position: relative;
    margin: 10px;
    padding: 8px 48px 8px 16px;
    font-size: 14px;
    border-radius: 2px;
    color: #fff;
    background: #f7f7f7;

}

.i-alert.i-alert-with-icon {

    top: 50%;
    left: 24px;
    margin-top: -21px;
    font-size: 28px

.i-alert-close {
    font-size: 12px;
