记录一下对这个组件的使用。
源代码是这样的:
- <el-form :model="dynamicValidateForm" ref="dynamicValidateForm" label-width="100px" class="demo-dynamic">
- <el-form-item
- prop="email"
- label="邮箱"
- :rules="[
- { required: true, message: '请输入邮箱地址', trigger: 'blur' },
- { type: 'email', message: '请输入正确的邮箱地址', trigger: ['blur', 'change'] }
- ]"
- >
- <el-input v-model="dynamicValidateForm.email"></el-input>
- </el-form-item>
- <el-form-item
- v-for="(domain, index) in dynamicValidateForm.domains"
- :label="'域名' + index"
- :key="domain.key"
- :prop="'domains.' + index + '.value'"
- :rules="{
- required: true, message: '域名不能为空', trigger: 'blur'
- }"
- >
- <el-input v-model="domain.value"></el-input><el-button @click.prevent="removeDomain(domain)">删除</el-button>
- </el-form-item>
- <el-form-item>
- <el-button type="primary" @click="submitForm('dynamicValidateForm')">提交</el-button>
- <el-button @click="addDomain">新增域名</el-button>
- <el-button @click="resetForm('dynamicValidateForm')">重置</el-button>
- </el-form-item>
- </el-form>
- <script>
- export default {
- data() {
- return {
- dynamicValidateForm: {
- domains: [{
- value: ''
- }],
- email: ''
- }
- };
- },
- methods: {
- submitForm(formName) {
- this.$refs[formName].validate((valid) => {
- if (valid) {
- alert('submit!');
- } else {
- console.log('error submit!!');
- return false;
- }
- });
- },
- resetForm(formName) {
- this.$refs[formName].resetFields();
- },
- removeDomain(item) {
- var index = this.dynamicValidateForm.domains.indexOf(item)
- if (index !== -1) {
- this.dynamicValidateForm.domains.splice(index, 1)
- }
- },
- addDomain() {
- this.dynamicValidateForm.domains.push({
- value: '',
- key: Date.now()
- });
- }
- }
- }
- </script>
但是我的需求是:自动增减的表单项是下拉选,从所有人中选择审批人,自动增减的就是审批人1,审批人2...
面对源代码的增减项是一个input输入框,我是这样改的:
- <el-form-item
- v-for="(user, index) in model.userList"
- :label="'审批人' + (index + 1)"
- :rules="{required: true, message: '审批人不能为空', trigger: 'blur'}">
- <template slot-scope="scope">
- <el-select
- v-model="model.userList[index]"
- value-key="userId" placeholder="请选择">
- <el-option
- v-for="item in teacherList"
- :key="item.userId"
- :label="item.userName"
- :value="item">
- </el-option>
- </el-select>
- <el-button @click.prevent="removeDomain(user)">删除</el-button>
- </template>
- </el-form-item>
- <el-form-item>
- <el-button @click="addDomain">添加审批人</el-button>
- <el-button type="primary" @click="goBack">返回</el-button>
- <el-button type="primary" @click="saveModel">保存</el-button>
- </el-form-item>
- </el-form>
还有一点值得记录得就是下拉选,如果想保存的是整个对象,就得用上value-key。
下拉选的回显,之前的属性和下拉选List里的对象的属性是一样的才能显示出来,不然是不能回显的。
好了,还有好多工作待完成,这篇写的着实潦草了些,不过因为昨天我用到这个功能的时候以为我早就记录过了,结果并没有,所以非常有必要先记录下来。以后有时间在完善吧。
