vue中如何去掉空格的方法实现

function genDefaultModel (
 el: ASTElement,
 value: string,
 modifiers: ?ASTModifiers
): ?boolean {
 const type = el.attrsMap.type
 const { lazy, number, trim } = modifiers || {}
 const needCompositionGuard = !lazy && type !== \'range\'
 const event = lazy
  ? \'change\'
  : type === \'range\'
   ? RANGE_TOKEN
   : \'input\'

 let value  = \'$event.target.value\'
  // 去掉空格
 if (trim) {
  value  = `$event.target.value.trim()`
 }
 if (number) {
  value  = `_n(${value })`
 }

 let code = genAssignmentCode(value, value )
 if (needCompositionGuard) {
  code = `if($event.target.composing)return;$[code]`
 }

 addProp(el, \'value\', `(${value})`)
 addHandler(el, event, code, null, true)
 if (trim || number || type === \'number\') {
  addHandler(el, \'blur\', \'$forceUpdate()\')
 }
}

<template>
 <div @input=\"removeSpaces\">
  <el-input v-model.trim=\"value\"></el-input>
 </div>
</template>
< >
  export default {
    data() {
      return {
        value : \'\'
      }
    },
    methods: {
      removeSpaces(event) {
        if(event.target.composing){
          return
      }
      this.value = event.target.value.trim()
      this.value = this.value.replace(\"\\\\u200B\",\"\")
     }
    }
  }
