在elementUI中,Form组件提供了表单验证的功能,只需要通过 rules 属性传入约定的验证规则, 并将Form-Item的prop属性设置为需校验的字段名即可
具体的可拜读elementUI官网
- <!-- 编辑界面 -->
- <el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @before-close="closeDialog">
- <el-form label-width="120px" :model="editForm" :rules="rules" ref="editForm">
- <el-form-item label="文章标题" prop="title">
- <el-input size="small" v-model="editForm.title" auto-complete="off" placeholder="请输入文章标题"></el-input>
- </el-form-item>
- <el-form-item label="文章内容" prop="body">
- <el-input size="small" v-model="editForm.body" auto-complete="off" placeholder="请输入文章内容"></el-input>
- </el-form-item>
- </el-form>
- <div slot="footer" class="dialog-footer">
- <el-button size="small" @click="closeDialog">取消</el-button>
- <el-button size="small" type="primary" class="title" @click="submitForm('editForm')">保存</el-button>
- </div>
- </el-dialog>

可在官网中查找一个表单校验规则rules与el-form表单中的rules相对应,根据自己的需求改吧改吧


- rules: {
- title: [{
- required: true,
- message: '请输入活动名称',
- trigger: 'blur'
- },
- {
- min: 3,
- max: 5,
- message: '长度在 3 到 5 个字符',
- trigger: 'blur'
- }
- ],
- body: [{
- required: true,
- message: '请输入活动名称',
- trigger: 'blur'
- }]
- },
- submitForm(formName) {
- this.$refs[formName].validate((valid) => {
- if (valid) {
- alert('submit!');
- } else {
- console.log('error submit!!');
- return false;
- }
- });
当我点击新增时窗口名应该显示为新增文章,当我点击编辑时窗口名则为编辑文章。
并且点击编辑窗口时,数据要能够回显,要拿到编辑前的数据。
实现思路:在方法中传入下标index和当前行row两个参数,根据当前行来判断,如果存在row即为编辑,不存在则是新增
- handleEdit(index, row) {
- this.clearData();
- this.editFormVisible = true;
- if(row){
- this.title = '编辑窗体';
- this.editForm.id = row.id;
- this.editForm.title = row.title;
- this.editForm.body = row.body
-
-
- }
- else{
- this.title = '新增窗体';
- }
- },
同时在关闭窗口时要清空数据,这里定义一个清空数据的方法,并在关闭窗口的方法中调用
- clearData() {
- this.title = '';
- this.editForm.id = 0;
- this.editForm.title = '';
- this.editForm.body = '';
- this.editFormVisible = false;
- },
- closeDialog() {
- this.clearData();
- },
由于增加与编辑的方法名是一样的,所以在表单提交时我们需要判断触发这个方法时是增加还是编辑。
实现思路:
elementUI与layui一样,编辑数据时都不再需要向后台获取id,而是拿到该条数据的下标与当前行数,而新增时不需要,id为0,所以我们可以通过判断id是否为0来辨别增加和编辑两个方法。在通过axios拿到不同的接口数据
- submitForm(formName) {
- this.$refs[formName].validate((valid) => {
- if (valid) {
- let url;
- if (this.editForm.id == 0) {
- url = this.axios.urls.SYSTEM_ARTICLE_ADD;
- } else {
- url = this.axios.urls.SYSTEM_ARTICLE_EDIT;
- }
- // let url = 'http://localhost:8080/T216_SSH/vue/userAction_login.action';
-
- this.axios.post(url, this.editForm).then((response) => {
- console.log(response);
- this.clearData();
- this.search();
- }).catch(function(error) {
- console.log(error);
- });
- } else {
- console.log('error submit!!');
- return false;
- }
- });
- }
-
- },
删除功能与编辑功能一样,都要拿到该条数据的下标和当前行数。在通过axios拿到删除方法的接口数据,并且提交时将当前行id赋给id即可
- deleteUser(index, row) {
- let url = this.axios.urls.SYSTEM_ARTICLE_DEL;
- this.axios.post(url, {
- id: row.id
- }).then((response) => {
- console.log(response);
- this.clearData();
- this.search();
- }).catch(function(error) {
- console.log(error);
- });
- },
