表单验证
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
<el-form-item label="活动名称" prop="name">
<el-form :model="ruleForm" :rules="rules" ref="ruleForm"
注1:有多个表单,怎么在提交进行区分?
我们在rules这里写了对表单的验证规则,但是我们如何在methods里进行指定的表单进行认证,
所以我们一开始就在el-form里写了 ref="ruleForm",我们在methods里就可以用
注2:清空表单验证信息
this.$refs[formName].resetFields();

在<template>上使用特殊的slot-scope 特性,可以接收传递给插槽的prop
功能:
1、dialog布局
2、表单验证
3、新增功能
4、修改功能
5、删除功能
核心代码:
export default { data() { return { listData: [], formInline: { page: 1, rows: 10, title: '' }, total: 0, editForm: { id: 0, title: '', body: '' }, editFormVisible: false, title: '', rules: { title: [{ required: true, message: '', trigger: 'blur' }, { min: 3, max: 5, message: '长度在3到5个字符', trigger: 'blur' }], body: [{ required: true, message: '', trigger: 'blur' }] } }; }, methods: { doSearch(params) { let url = this.axios.urls.SYSTEM_ARTICLE_LIST; this.axios.post(url, params).then((response) => { this.listData = response.data.result; this.total = response.data.pageBean.total; }).catch(function(error) { console.log(error); }); }, handleSizeChange(rows) { this.formInline.page = 1; this.formInline.rows = rows; this.search(); }, handleCurrentChange(page) { this.formInline.page = page; this.search(); }, search() { this.doSearch(this.formInline); }, closeDialog() { }, 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; } this.axios.post(url, this.editForm).then((response) => { this.cleaerData(); this.search(); }).catch(function(error) { console.log(error); }); } else { console.log('error'); return false; } }); }, handleAdd() { this.cleaerData(); this.editFormVisible = true; this.title = '新增文章' }, handleEdit(index, row) { this.editFormVisible = true; this.title = '编辑文章'; this.editForm.id = row.id; this.editForm.title = row.title; this.editForm.body = row.body }, deleteUser(index, row) { let url = this.axios.urls.SYSTEM_ARTICLE_DEL; this.axios.post(url, { id: row.id }).then((response) => { this.cleaerData(); this.search(); }).catch(function(error) { console.log(error); }); }, cleaerData() { this.editFormVisible = false; this.title = ''; this.editForm.id = 0; this.editForm.title = ''; this.editForm.body = '' } }, created() { this.doSearch({}); } }
