记录

1. vue-element-admin 模版：https://github.com/PanJiaChen/vue-admin-template
   input 属性 autocomplete="off" 关闭输入记录 onpaste="return false" 禁止粘贴
   Element UI中el-dialog中内容超出自定义滚动条：

.sketch_content {
  // 必须有高度 overflow 为自动
  overflow: auto;
  height: 434px;
  border-top: 1px solid #eff1f4;
  // border-bottom: 1px solid #eff1f4;
  padding: 0px 30px 11px 27px;

  // 滚动条的样式,宽高分别对应横竖滚动条的尺寸
  &::-webkit-scrollbar {
    width: 3px;
  }

  // 滚动条里面默认的小方块,自定义样式
  &::-webkit-scrollbar-thumb {
    background: #abb7c8;
    border-radius: 2px;
  }

  // 滚动条里面的轨道
  &::-webkit-scrollbar-track {
    background: transparent;
  }
}

2. el-table 表格表头和单元格内容居中

      :header-cell-style='{"text-align":"center"}'
      :cell-style="{'text-align':'center'}"
      
      >

// vue弹窗后让滚动条每次都在最上面
let dialogDom = document.querySelector('.mf-scroll-top .el-dialog__body')
      dialogDom.scrollTop = 0

4. vue中使用tinymce时，打开弹窗只有第一次有初始化内容，解决方法，直接给一个唯一值，我直接使用

Math.random()。 :key="memSetType == 1?'1':Math.random()"

<tinyEditor :disabled="memSetType == 3 " 
:key="memSetType == 1?'1':Math.random()"
 id="tinyDom" 
@input="newValue" 
:value="form1.description"/>

5. 微信小程序

缩放模式，宽度不变，高度自动变化，保持原图宽高比不变
mode='widthFix'

6. react 修改input组件的placeholder样式
   placeholder-class= 'placeholder-style'
7. • 1.toLocaleTimeString() 返回时分秒 17:35:21
     conspole.log(new Date().toLocaleTimeString())

• 2.toLocalDateString() 返回年月日 2022/3/23
  console.log(new Date().toLocaleDateString())

8. 通过条件判断选择与否，类似单选

  <View className='name'> 
                          <View>
                          <Text style={{color:'#E43832',fontSize:'9px'}}>*</Text>
                           <Text className='nameLab'>性别：</Text>
                          </View>
                           <View  className="lastView wrapPro">
                            {sexList.map((item, index) => {
                                return (
                                <View
                                    className="lastView"
                                    key={item.value}
                                    onClick={() => {
                                        disabled ? '' : this.setState({  // 主要
                                            gender:item.value
                                        })
                                        }}
                                    >
                                    <Label for='name'></Label>
                                    <Image
                                    className="check"
                                    src={
                                        gender == item.value? // 条件判断谁选择了，给谁加上样式
                                            "https://saas-asset.oss-cn-hangzhou.aliyuncs.com/common/app/miniapp/dh/check_circular.png"
                                        : "https://saas-asset.oss-cn-hangzhou.aliyuncs.com/common/app/miniapp/dh/un_check_circular.png"
                                    }
                                    />
                                    <Text  id='name' className="title">{item.text}</Text>
                                </View>
                                );
                            })}
                           </View>

9. 进制转换 paresInt(转换的数，进制) parseInt(100,2)；将二进制100通过2进制转换为10进制

10. scrollTop() 的用法 链接：https://blog.csdn.net/muxi229/article/details/106849535

     let treeDom = document.querySelector(".tree-table");
      treeDom.scrollTop = 0;
