用vue-resource向后端提交数据

第一步:

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" class="demo-ruleForm">  
                <el-form-item label="用户名" prop="name">  
                    <el-input v-model="ruleForm.name"></el-input>  
                </el-form-item>  
                <el-form-item label="用户类型" prop="type">  
                    <el-select v-model="ruleForm.type" placeholder="请选择专利类型" style="width:500px;">  
                        <el-option label="一级管理员" value="1"></el-option>  
                        <el-option label="二级管理员" value="2"></el-option>  
                        <el-option label="三级管理员" value="3"></el-option>  
                        <el-option label="普通用户" value="4"></el-option>  
                    </el-select>  
                </el-form-item>  
                <el-form-item label="出生日期" prop="date">  
                    <el-input v-model="ruleForm.date"></el-input>  
                </el-form-item>  
                <el-form-item label="备注" prop="intro">  
                    <el-input type="textarea" v-model="ruleForm.intro" :rows="10"></el-input>  
                </el-form-item>  
                <el-form-item>  
                    <el-button type="primary" @click="submitForm('ruleForm')">提交</el-button>  
                </el-form-item>  
</el-form>  

第二步:在data里面定义表单内容的字段及表单的约束规则

data() {  
      return {  
        ruleForm: {  
              name: '',  
              type: '',  
              date: '',  
              intro: '',  
          }  
      }  
 rules: {  
          name: [  
            { required: true, message: '请输入用户名', trigger: 'blur' },  
            { min: 1, max: 20, message: '长度在 1 到20个字符', trigger: 'blur' }  
          ],  
          type: [  
            { required: true, message: '请选择用户类型', trigger: 'change' }  
          ],  
          date: [  
            { required: true, message: '请输入出生日期', trigger: 'blur' },  
            { min: 1, max: 100, message: '长度在 1 到 100 个字符', trigger: 'blur' }  
          ],  
          intro: [  
            { required: true, message: '请输入备注', trigger: 'blur' },  
            { min: 50, max: 500, message: '请输入至少50个字', trigger: 'blur' }  
          ],  
        }  
}  

第三步:定义提交表单的方法

methods:{  
submitForm(formName) {  
            this.$refs[formName].validate((valid) => {  
                if (valid) {  
            this.$http.get(baseURL+"api/create?table=user&"+getParamsString(param)).then(function(res){  
                        if(res.body==1){  
                            this.$alert("提交成功", '提交结果', {  
                                confirmButtonText: '确定',  
                                type: 'success',  
                                callback: action => {  
                                },  
                            });  
                        }  
                        else{  
                            this.$alert("提交失败", '提交结果', {  
                                confirmButtonText: '确定',  
                                type: 'warning',  
                                callback: action => {  
                                },  
                            });  
                        }  
                    })  
                } else {  
                    console.log('error submit!!');  
                    return false;  
                }  
            });  
        }  
}  

注意:前提是你的数据库里面有一张名为user的表,表里面有name,type,date,intro字段,并且后端的接口啥的都已经定义好的情况下,不然是不会成功的
