看b站直播有哪些seo优化交流

一、 最终效果

二、实现了功能

1、支持输入正整数---设置`specifyType=integer`
2、支持输入数字（含小数点）---设置`specifyType=decimal`，可设置`decimalLimit`来调整小数点位数
3、支持输入手机号--设置`specifyType=phone`
4、支持输入身份证号---设置`specifyType=idCard`
4、支持失焦后校验错误提示
5、支持title自定义或者slotLabel插槽
6、支持inputType输入框类型可选值：input/select 
7、支持自带下拉选择

三、TInput 参数配置

1、代码示例：

<TInput v-model="value" titlt="标题" />

2. 配置参数（Attributes）继承wu-input及wu-popup的所有参数事件

参数	说明	类型	默认值
v-model	input绑定值	String /number	-
v-model:select-value	inputType:select 的绑定值	String /number	-
title	label标题	String	-
inputType	输入框类型可选值：input/select	String	input
required	是否必填红点标识	boolean	false
decimalLimit	小数点后保留几位	number	2
specifyType	指定输入类型"text"/“decimal”/“phone” /“integer” / “idCard”	String	text
showThousands	是否显示千分位	boolean	false
isShowErrorTip	输入框失焦是否提示错误信息	boolean	false
isLink	是否展示右侧箭头(inputType=select自动展示)	boolean	false
iconArrow	右侧箭头图标	String	‘arrow-right’
iconArrowColor	右侧箭头颜色	String	#969799
isColon	label标题是否显示冒号	boolean	true
isShowBorder	是否显示下边框	boolean	false
list	inputType=select自带下拉数据源	array	[]
customKey	列表项自定义key	String	key
customLabel	列表项自定义label	string	label
popupTitle	自带下拉框标题显示	string	-
isPopupTitleBorder	自带下拉框标题与列表边框显示	boolean	false

3. Events

事件名	说明	返回值
clickInput	list没有设置时点击input触发	-

4. Slot

事件名	说明
slotInput	右侧input框插槽
slotLabel	左侧label插槽
prefix	input前缀插槽
suffix	input后缀插槽

四、源码
