value反显为label

一、value反显为label

getLabel (list, value) {
  if (list && list.length > 0 && value) {
    const form = list.find((item) => item.value === value)
    return form ? form.label : value
  } else {
    return ''
  }
}

二、value组成的字符串反显为label

const wayOpt = [
  { label: '线上', value: '0' },
  { label: '线下', value: '1' }
]
form.way = '0, 1'
from.wayName = this.getStringName(from.way, wayOpt，'value')

getStringName (string, list, key) {
 if (string) {
   const splitList = string.split(',')  
   const name = []
   splitList.forEach((item) => {
     list.forEach((l) => {
       if (item === l[key]) {
         name.push(l.label)
       }
     })
   })
   return name.join(',')
 } else {
   return ''
 }
}
