HarmonyOS web组件注入JS代码

参考代码如下，直接在字符串中编写代码：

initJSBridge(sessionID: string){
  const session = this.getSession(sessionID)
  session.controller.runJavaScript(`
const JSBridgeMap = {}
let callID = 0

function JSBridgeCallback (id, params){
JSBridgeMap[id](params)
JSBridgeMap[id] = null
delete JSBridgeMap[id]
}

window.JSBridge = {
call(method, params, callback){
const id = callID++
const paramsObj = {
callID: id,
data: params || null
}
JSBridgeMap[id] = callback || (() => {})
JSBridgeHandle.call(method, JSON.stringify(paramsObj))
},
}
`)
}
