我在 Eclipse 中，編寫 Java GUI/腳本，運行無頭 chromedriver，我在嘗試在驅動程序中加載 html2canvas.js [1] [2]庫時遇到問題，然后調用我在其上編寫的函數瀏覽器中的庫；我收到此代碼的未定義錯誤：String ss1ScriptLoc = "C:\\Users\\me\\Desktop\\resources\\html2canvas.min.js";String ss2ScriptLoc = "C:\\Users\\me\\Desktop\\resources\\takeScreenShot.js";je.executeScript(        "var headID1 = document.getElementsByTagName('head')[0]; "        + "var newScript1 = document.createElement('script'); "        + "newScript1.type = 'text/javascript'; "        + "newScript1.src = '" + ss1ScriptLoc + "'; "        + "headID1.appendChild(newScript1); "        + "var headID2 = document.getElementsByTagName('head')[0]; "        + "var newScript2 = document.createElement('script'); "        + "newScript2.type = 'text/javascript'; "        + "newScript2.src = '" + ss2ScriptLoc + "'; "        + "headID2.appendChild(newScript2); "        + "$(document).ready( function () { takeScreenShot(); });"    );這會導致未定義函數“takeScreenShot();”的錯誤 我以為我已經在本地 .js 文件中定義了它。Starting ChromeDriver 75.0.3770.140 (-refs/branch-heads/3770@{#1155}) on port 48415Only local connections are allowed.Please protect ports used by ChromeDriver and related test frameworks to prevent access by malicious code.Aug 05, 2019 9:36:53 AM org.openqa.selenium.remote.ProtocolHandshake createSessionINFO: Detected dialect: W3Cjava.util.concurrent.ExecutionException: org.openqa.selenium.JavascriptException: javascript error: takeScreenShot is not defined  (Session info: headless chrome=75.0.3770.142)Caused by: org.openqa.selenium.JavascriptException: javascript error: takeScreenShot is not defined  (Session info: headless chrome=75.0.3770.142)Build info: version: '3.141.59', revision: 'e82be7d358', time: '2018-11-14T08:25:48'System info: host: '', ip: '', os.name: 'Windows 10', os.arch: 'amd64', os.version: '10.0', java.version: '1.8.0_191'Driver info: org.openqa.selenium.chrome.ChromeDriver
