鸿蒙 webview 出现 Can not read properties of null (reading ‘getltem‘) 错

1, 先看原来的代码

import web_webview from '@ohos.web.webview';interface PerUrl {url: string,age: number
}
@Component
export  struct Url {controller: web_webview.WebviewController = new web_webview.WebviewController();ports: web_webview.WebMessagePort[] = [];@LinksonUrl:PerUrlbuild() {Column() {Text('url的值'+ `${this.sonUrl.url} 今年 ${this.sonUrl.age} 岁`)Web({ src: this.sonUrl.url, controller: this.controller })}}
}

2, 看看解决方案 加上 这两行代码

.javaScriptAccess(true)
.domStorageAccess(true)

 build() {Column() {Text('url的值'+ `${this.sonUrl.url} 今年 ${this.sonUrl.age} 岁`)Web({ src: this.sonUrl.url, controller: this.controller }).javaScriptAccess(true).domStorageAccess(true)}}
}
