vue表单rules校验是动态的
表单代码如下：
<el-form ref="form" label-width="60px" :model="formData" :rules="newRules"><el-form-item label="分类类型" prop="type"><el-selectv-model="formData.type":data="typeList"/></el-form-item><el-form-item label="预算科目" prop="subjectTree"><el-selectv-model="formData.subjectTree":data="valueList"/></el-form-item><el-form-item label="资金管理方式" prop="value"><el-selectv-model="formData.value":data="valueList"/></el-form-item></el-form>
rules代码：
本来是把rules写在data里的 发现校验并未生效 后来只能放在computed里
computed: {newRules() {const { formData } = thisreturn {type: [{required: true,message: this.$t('validator.required', { name: '分类类型' })}],subjectTree: [{required: formData.type === '0' ? true : false,message: this.$t('validator.required', { name: '预算科目' })}],value: [{required: formData.type === '1' ? true : false,message: this.$t('validator.required', { name: '资金管理方式' })}]}}},
