  • vue element-ui的el-table和el-form嵌套使用表单校验


    表格是el-table自动获取的后台数据,每行都有el-input的验证,这样一个rules的规则就不能匹配到每一行,所以要是用动态的prop和rules规则
    关键一
    此处 data中定义的变量,params:表格数据,后台查询获得;paramsRules:校验规则
    关键二
    此处 :model、:rules
    关键三
    此处 :prop="'params.' + scope.$index + '.min'"和:rules="paramsForm.paramsRules.min"即动态对应上每行数据的校验规则
    <template>
      <div>
        <el-form :model="paramsForm" ref="rForm" :rules="paramsForm.paramsRules">
          <el-table
            :data="paramsForm.params"
