Interpretation and analysis of WeChat applet components: input input box

input input boxComponent description:

This article introduces the input input box various parameters and characteristics.

input input boxThe sample code runs as follows:

The following is the WXML code:

##[XML]

<view class="content">
type：有效值：text 感觉没什么区别
<input  placeholder="type=text" type="text" value="" />
<input  placeholder="type=number" type="number" value="" />
<input  placeholder="type=idcard" type="idcard" value="" />
<input  placeholder="type=digit" type="digit" value="" />
password：
<input   type="text" password="{{false}}" placeholder="请输入密码"/>
<input   type="text" password="{{true}}" placeholder="请输入密码"/>
placeholder：
<input  placeholder="占位符" />
disable:
<input  placeholder="disable={{false}}" disabled=&#39;{{false}}&#39;/>
<input  placeholder="disable={{true}}" disabled=&#39;{{true}}&#39;/>
最大长度：
<input   maxlength="10" placeholder="maxlength=&#39;10&#39;最多长度10字符"/>
<input   maxlength="5" placeholder="maxlength=&#39;5&#39;最多长度5字符"/>
<input   maxlength="-1"  placeholder="值为-1，则不限制长度"/>
</view>

The following is the WXSS code:

[JavaScript]

.content{
  border:1px black solid;
  margin: 10px;
  font-size: 10pt;
  padding: 5px;
}
input{
  border:1px red solid;
margin: 5px;
}

The following is the WXML code:

[XML]

<view class="content">
bindinput="当内容改变"
<input  bindinput="bindinput"/>
bindfocus:当获取焦点
<input  bindfocus="bindfocus"/>
bindblur：当失去焦点触发
<input  bindblur="bindblur"/>
内容：
<view style="color:blue">
{{log}}
</view>
</view>

The following is the JS code:

[JavaScript]

Page({
  data:{
    log:'事件触发'
  },
  bindblur:function(e){
    var value=e.detail.value;
    this.setData({
      log:"bindblur失去焦点.输入框值="+value
    })
  },
  bindinput:function(e){
    var value=e.detail.value;
    this.setData({
      log:"bindinput内容改变.输入框值="+value
    })
  },
  bindfocus:function(e){
    var value=e.detail.value;
    this.setData({
      log:"bindfocus获取焦点.输入框值="+value
    })
  }
})

The following is the WXSS code:

[JavaScript]

.content{
  border:1px black solid;
  margin: 10px;
  font-size: 10pt;
  padding: 5px;
}
input{
  border:1px red solid;
margin: 5px;
}

Component properties:

##PropertiesDescriptionTypeDefault valuevalueInitial content of the input boxStringtypeValid values: text, number, idcard, digitStringtextpassword is the password typeBooleanfalse##placeholder##placeholder-style##input -placeholderWhether it is disabledBooleanfalseMaximum input length, set to Auto focus, pull up the keyboard. When there can only be one input or textarea tag in the page, set the auto-focus attribute Get focus (currently not supported by development tools)

The input box is When empty placeholder	String
Specify the style of placeholder	String		##placeholder-class
Specify the style class of placeholder	String		disabled
			maxlength
-1 There is no maximum length limit when	Number ##140		auto-focus
Boolean	false		focus
Boolean	false		bindinput	除了date/time类型外的输入框，当键盘输入时，触发input事件，处理函数可以直接 return 一个字符串，将替换输入框的内容。	EventHandle
bindfocus	输入框聚焦时触发event.detail = {value: value}	EventHandle
bindblur	输入框失去焦点时触发event.detail = {value: value}	EventHandle

属性解析：

下面是WXML代码：

[XML]

<!--属性：-->
<!--value：输入框内容-->
<input value="内容"/>
<!--type：有效类型text，number,idcard,digit，小编感觉其他三个和text没有明显区别,不清楚是什么问题，正常number应该只允许输入数字，但结果和text一样-->
<input type="text"/>
<input type="number"/>
<input type="idcard"/>
<input type="digit"/>
<!--password：密码格式 boolean需要{{}}表示-->
<input password="{{true}}"/>
<input password/>  等同于  <input password="{{false}}"/>
<!--placeholder：占位符，对输入框内容提示-->
<input placeholder="占位符" placeholder-class="占位符静态样式"   placeholder-style="占位符动态样式，可用{{}}进行动态赋值"/>
<!--disabled：控制标签有效,或者失效状态，在失效状态，不能获取该值-->
<input disabled="{{true}}"/>
<input disabled/> 等同于 <input disabled="{{false}}"/>
<!--maxlength:内容长度限制,默认140-->
<input  maxlength="100"/>
<input  maxlength/> 等同于 <input  maxlength="140"/>
<!--focus:初始化时，获取输入焦点(目前开发工具暂不支持)-->
<input  focus="{{true}}"/>
<input focus/> 等同于 <input focus="{{false}}"/>
<!--auto-focus：当界面只有一个input,自动获取焦点-->
<input   auto-focus="{{true}}"/>
<input   auto-focus/> 等同于 <input auto-focus="{{false}}"/>
<!--事件：-->
<!--bindinput:当内容改动时触发-->
<input bindinput="自己定义函数名">
<!--bindfocus:当获取焦点，可用输入状态时触发-->
<input bindfocus="自己定义函数名">
<!--bindblur：当失去焦点触发-->
<input bindblur="自己定义函数名">
