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
