前言:

继上篇博客来写我们的增删改以及表单验证

增删改查

首先先定义接口

数据样式,我们可以去elementUI官网去copy我们喜欢的样式

   <!-- 编辑窗体 -->
    <el-dialog :title="title" :visible.sync="dialogFormVisible" @close="clear">
      <el-form :model="book" :rules="rules" ref="book">

表单验证

表单验证我们也可以去elementUI官网去copy一份

指定验证需要添加该有的属性

写我们的正则方法

  rules: {
          bookname: [{
            required: true,
            message: '请输入书籍名称',
            trigger: 'blur'
          }],
          price: [{
            required: true,
            message: '请输入书籍价格',
            trigger: 'blur'
          }],
          booktype: [{
            required: true,
            message: '请输入书籍类型',
            trigger: 'blur'
          }]
        }

最后就是我们的验证正则

 dosub() {

        this.$refs['book'].validate((valid) => {
          if (valid) {
            let url = this.axios.urls.SYSTEM_BookADD;
            if (this.title == '编辑窗体') {
              url = this.axios.urls.SYSTEM_BookUPD;
            }
            let params = {
              id: this.book.id,
              bookname: this.book.bookname,
              price: this.book.price,
              booktype: this.book.booktype
            }
            this.axios.post(url, params).then(d => {
              console.log(d);
              this.clear();
              this.query({});
              this.tableData = d.data.rows;
              this.total = d.data.total;
            }).catch(e => {

            })

          } else {
            console.log('error submit!!');
            return false;
          }
        });



      },
