el-form动态标题和输入值，并且最后一个输入框不校验

请叫我欧皇i2024-09-22 12:46

需求：给了固定的label，叫xx单位，要输入单位的信息，但是属性名称都一样的，UI画图也是表单的形式，所以改为动态添加的形式，实现方式也很简单，循环就完事了，连着表单校验也动态

1.效果如下

2.代码实现+讲解

因为需求是最后一个单位没有必要必填，所以在rules这里判断了一下，主要就是循环遍历了el-form-item，之后prop为了区分也是用index来区分了

html 复制代码

 <el-dialog title="新建单位" :close-on-click-modal="false" :close-on-press-escape="false" :visible.sync="unitDialog" width="30%">
            <el-form
                :model="formInline"
                ref="unitRuleForm"
                label-width="130px"
                class="demo-form-inline"
                label-position="left"
            >
                <el-form-item
                    v-for="(item, index) in formInline.formData"
                    :key="index"
                    :label="item.organizations_type"
                    :prop="'formData[' + index + '].organizations_name'"
                    :rules="
                        index < formInline.formData.length - 1
                            ? {
                                  required: true,
                                  message: `${item.organizations_type}不能为空`,
                                  trigger: 'blur'
                              }
                            : null
                    "
                >
                    <el-input v-model="item.organizations_name"></el-input>
                </el-form-item>
            </el-form>
            <span slot="footer" class="dialog-footer">
                <el-button @click="unitDialog = false">取 消</el-button>
                <el-button type="primary" @click="saveUnitData()">确 定</el-button>
            </span>
        </el-dialog>
