The information I get on the page is always the source code, I can't get the rendered page code.
How can I get the page after the dynamic rendering is complete, just like checking it in Chrome?
And my code like this:

fun main(args: Array<String>) {
    val client = WebClient(BrowserVersion.CHROME).apply {
        options.apply {
            isCssEnabled = true
            isJavaScriptEnabled = true
            isThrowExceptionOnScriptError = false
            isRedirectEnabled = true
            isActiveXNative = true
        }
        javaScriptEngine = CustomJsEngine(this)
        ajaxController = NicelyResynchronizingAjaxController()
        waitForBackgroundJavaScript(10 * 1000)
    }
    Damai.start(client)
    client.close()
}

object Damai {
    /**
     * 打开买票界面
     * @param client 浏览器实例
     */
    fun start(client: WebClient) {
        val scanner = Scanner(System.`in`)
//        val url = scanner.next()
        val url = "https://detail.damai.cn/item.htm?spm=a2oeg.home.card_0.ditem_1.591b23e1KA3wRj&id=601539289783"
        println("大麦网购票地址：")
        val homePage = client.getPage<HtmlPage>(url)
//        println(homePage.asText())
        val loginBtn = homePage.getFirstByXPath<HtmlSpan>(
                "//div[@class='dm-header-wrap']//div[@class='dm-header-box']//div[@class='right-header']" +
                        "//div[@class='box-header user-header']//div[@class='login-user show']" +
                        "//span[@class='span-box-header span-user']")
        startLogin(loginBtn.click())
    }
    /**
     * 进行登陆
     * @param page 点击后的登陆界面
     */
    private fun startLogin(page: HtmlPage) {
        val loginDiv = page.getHtmlElementById<HtmlDivision>("alibaba-login-iframe")
        println(loginDiv.asXml())
    }
}
