HarmonyOS webview加载html片段，是否有相关的api设置宽度的自适应

import web_webview from '@ohos.web.webview'; 
 
@Entry 
@Component 
struct WebComponent { 
  controller: web_webview.WebviewController = new web_webview.WebviewController(); 
  @State webResult:string = '' 
  build() { 
    Column() { 
      Text(this.webResult).fontSize(20) 
      Web({ src: $rawfile('index.html'), controller: this.controller }) 
        .javaScriptAccess(true) 
        .aspectRatio(1.5) 
        .onPageEnd(e => { 
          this.controller.runJavaScript( 
            'watchWindowSize()', 
            (error,result)=>{ 
              this.webResult=result 
              console.info("pageheight="+this.webResult); 
            } 
          ); 
        }) 
        .height(parseInt(this.webResult)) 
    } 
  } 
}

<script type="text/javascript"> 
  function watchWindowSize(){ 
    var h = document.body.clientHeight; 
    return h; 
  } 
  </script>
