在app中如何使weib-view不铺满全屏，自适应页面

　　				// #ifdef APP-PLUS
				//自建webview
				var currentWebview = this.$scope.$getAppWebview();
				var height = this.windowHeight - this.topHeight;
				if (this.activeIndex == 1) {
					var type = uni.getSystemInfoSync().platform; //判断是ios还是安卓
					wv = plus.webview.create(this.docUrl, "webview", {
						plusrequire: "none",
						'uni-app': 'none',
						top: type == 'android' ? this.topHeight + 90 : this.topHeight + 75,
						scalable: true,
						height: height
					})
					currentWebview.append(wv);
				} else {
					plus.webview.close(wv);
				}
				// #endif

var currentWebview = this.$scope.$getAppWebview();//此对象相当于html5plus里的plus.webview.currentWebview()。在uni-app里vue页面直接使用plus.webview.currentWebview()无效 

我这里是点击tab选项卡展示

        // #ifdef APP-PLUS         //自建webview         var currentWebview = this.$scope.$getAppWebview();         var height = this.windowHeight - this.topHeight;         if (this.activeIndex == 1) {           var type = uni.getSystemInfoSync().platform; //判断是ios还是安卓           wv = plus.webview.create(this.docUrl, "webview", {             plusrequire: "none",             'uni-app': 'none',             top: type == 'android' ? this.topHeight + 90 : this.topHeight + 75,             scalable: true,             height: height           })           currentWebview.append(wv);         } else {           plus.webview.close(wv);         }         // #endif
