PKPM BIMViewer的使用
模型的使用，目前有两个方案，
一个是使用全局组件，在单页面的主页面中进行嵌套
<template> <div id="model"> <!-- 这样的写的目的是为了销毁的干净 --> <div :id="obvContainer" :class="{is_show:!isShow}"> <div :id="obv"></div> </div> </div> </template>
一个是使用iframe使用外部网页的嵌入
<template> <!-- 模型的嵌入 --> <iframe id="view3d" :src="iframeSrc" width="100%" height="100%" frameborder="0" scrolling="none" class="showmodelIframe"></iframe> </template>
iframe实际上嵌套的是另一个网页

iframe父子之间进行交互，子组件可以调用vue里面的方法向vue传数据，实现交互
mounted() { this.loadModel() if (this.moduleName) { this.getBimboxUrlRequest() } window['setObvApiWrapper'] = a => { this.setObvApiWrapper(a) } window['setMapGuid'] = a => { this.setMapGuid(a) } window['setClickMarkEvent'] = a => { this.setClickMarkEvent(a) } //setClickMarkEvent },
根据需要，我们都在封装好的model或者iframeModel组件中把对应的模型操作方法写好，然后调用组件的时候通过ref属性之间调用方法
methods: { /**如果页面有维绿大厦，原来也有维绿大厦 就不卸载维绿大厦，否则全部卸载 */ unloadModel() { var models = this.obvApiWrapper.getObvApi().getModels() for (var i = 0; i < models.length; i++) { this.obvApiWrapper.unloadModel(models[i].id) } }, /**点击标注的事件 */ setClickMarkEvent(a) { this.$emit('clickMarkEvent', a) }, /**初始化模型视图之后，将 obvApiWrapper模型操作对象传过来*/ setObvApiWrapper(a) { this.obvApiWrapper = a this.getBimboxUrlRequest() }, /**初始化模型视图之后，将 mapGuid传过来，这个时候模型肯定加载完成*/ setMapGuid(a) { this.mapGuid = a this.$emit('obvApiWrapper', this.obvApiWrapper) }, /**发送请求获取到模型地址，然后进行加载模型：满足多模型加载 */ async getBimboxUrlRequest() { var that = this var res = await ObvApi.getBimboxUrl(this.buildingId, this.moduleName) if (res.data.code == 200 && res.data.result && res.data.result.length > 0) { res.data.result.forEach(element => { if (element.name) { setTimeout(that.loadDocument(element.name), 2000) } }) } else { this.bimBoxUrl = this.defaultBimboxUrl } }, /**初始化模型环境，application、view */ loadModel() { console.log('loadModel') var that = this getAuth(this.$store.getters.bjInfo) getAccessToken(function(access_token, expires_in) { let url = '/static/obv/page/model/model.html?&token=' + access_token + '&expires=' + expires_in + '&r=' + Math.random() that.iframeSrc = url }) }, /**加载文档和模型 */ loadDocument(urn) { if (this.obvApiWrapper) { this.obvApiWrapper.loadDocumentByUrn( urn, function handleResolve() { //将obvApi返回父节点 }, function(err) { // that.$message(err); } ) } }, /**关联模型,传入 存有xdbguid的数组 */ linkObject(guidArr) { var that = this if (this.obvApiWrapper == '' && this.mapGuid == {}) { this.$message('模型未加载完，点击无法响应！') this.$emit('loading', false) return } //设置默认视角 var nodeIds = [] var count = 0 for (var k in this.mapGuid) { if (guidArr.indexOf(k) !== -1) { nodeIds.push(this.mapGuid[k]) count++ if (count == guidArr.length) { return nodeIds //this.obvApiWrapper.setIsolation() } } } }, //创建标注 createMarker(markerItem, item, message) { this.obvApiWrapper.createMarker(markerItem, item, message) this.$emit('loading', false) }, //清空标注 clearMarkers: function(obvApi) { this.obvApiWrapper.clearMarkers() this.markedNodeIds = [] this.$emit('loading', false) } }
