HarmonyOS 鸿蒙Next web组件使用this.controller.loadData(this.data, "text/html", "UTF-8", "", "")的方式，怎么让js生效？

import { webview } from ‘@kit.ArkWeb’;

@Entry
@Component
struct Index2 {
controller = new webview.WebviewController();
build() {
Column() {
Web({ src: “”, controller: this.controller, renderMode: RenderMode.SYNC_RENDER })// 加载html文本数据
.backgroundColor(Color.Orange)
.layoutMode(WebLayoutMode.FIT_CONTENT)
.onControllerAttached(() => {
this.controller.loadData(this.data, “text/html”, “UTF-8”, “”, “”)
})
}.width(‘100%’)
}
data =

webviewstyle.css

body {
margin: 0px;
padding: 1px;
font-size:24px;
color:#ff0000;
}<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>
