目录
一、表单验证
1.1 出现表单组件 el-form
这里我们参照官网可以去form组件中kopi，然后进行对应的值改变
<!-- 编辑界面 -->
<el-dialog :title="title" :visible.sync="editFormVisible" width="30%" @click="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>
1.2 通过点击 新增/编辑将表单对应窗口弹出
通过写方法让其对应的表单显示出来
handleEdit() {
//展示新增文章的表单窗体
this.editFormVisible = true;
}
1.3 给表单设置规则 rules
给表单增加校验规则
rules: {
title: [{
required: true,
message: '请输入文章标题',
trigger: 'blur'
},
{
min: 5,
max: 10,
message: '长度在 5 到 10 个字符',
trigger: 'blur'
}
],
body: [{
required: true,
message: '请输入文章内容',
trigger: 'blur'
}],
}
1.4 当表单提交时要校验规则
submitForm(formName) {
this.$refs[formName].validate((valid) => {
if (valid) {
alert('submit!');
} else {
console.log('error submit!!');
return false;
}
});

return false;

});
}
},
//钩子函数
created() {
this.doSearch({});
}
}
</script>
<style>
</style>
效果
存在问题：有缓存，而且后期我们编辑和增加弹出的是同一个窗口，要进行判断（后面CRUD优化）
二、CRUD
2.1 保障编辑窗体正常弹出
因为我们编辑和新增用的是同一个方法，所有我们要再其进行判断弹框，因为我们有缓存问题，所有我们还要新增一个清除缓存的方法，在关闭窗体调用

效果
点击新增
点击编辑
2.3 删除
注意删除只要传入相对应的id即可
删除方法
在deleteUser(index, row) {
this.$confirm('此操作将永久删除该文件, 是否继续?', '提示', {
confirmButtonText: '确定',
cancelButtonText: '取消',
type: 'warning'
}).then(() => {
let url = this.axios.urls.SYSTEM_ARTICLE_DEL;
this.axios.post(url, {id:row.id}).then(t => {
this.$message({
type: 'success',
message: '删除成功!'
});
this.clearData(); //关闭清空
this.search(); //查询
}).catch(e => {
})
}).catch(() => {
this.$message({
type: 'info',
message: '已取消删除'
});
});
},
点击删除
