这里的业务是通过关联的 id 发送不同的请求获取表单的数据，然后回显到页面中，整个的页面是由多个表单拼接起来的

        点击下一步的时候，获取下一个表单的内容。 

 // 查询
            getForm(index) {
                switch (index) {
                    case 0:
                        this.getFromInfo("inputForm",this.inputForm)
                        break;
                    case 1:
                        this.getFromInfo("projectApproval", this.projectApproval)
                        break;
                    case 2:
                        this.getFromInfo("preliminaryDesign", this.preliminaryDesign)
                        break;
                    case 3:
                        this.getFromInfo("landApproval", this.landApproval)
                        break;
                    case 4:
                        this.getFromInfo("landPlanning", this.landPlanning)
                        break;
                    case 5:
                        this.getFromInfo("invitationBids", this.invitationBids)
                        break;
                    case 6:
                        this.getFromInfo("fireDesignReview", this.fireDesignReview)
                        break;
                    case 7:
                        this.getFromInfo("expertArgumentation", this.expertArgumentation)
                        break;
                    case 8:
                        this.getFromInfo("constructionPermit", this.constructionPermit)
                        break;
                    case 9:
                        this.getFromInfo("qualitySupervisionRegistration", this.qualitySupervisionRegistration)
                        break;
                    case 10:
                        this.getFromInfo("safeSupervisionRegistration", this.safeSupervisionRegistration)
                        break;
                    case 11:
                        this.getFromInfo("buildRecordSubmission", this.buildRecordSubmission)
                        break;
                }
            },
            getFromInfo(formType, formData) {
                this.get('${ctx}/buildproject/' + formType + '/info', {id: this.inputForm.id}).then((res) => {
                    formData = res.data;
                    this[formType] = formData;
                })
            },

        getFromInfo接受两个参数（表单的名称，表单数据结构），然后发送相应的请求获取到数据，返回给到表单中，这里最重要的一步就是  this[formType] = formData; this[] 可以指向相应的对象。比如 fromType为 inputForm 时，this[inputForm] 等同于 this.inputForm
