javascript - Selenium ，java，js "Exception in thread "主“org.openqa.selenium.JavascriptException : missing ) after argument list"

Question

当我将以下代码放入 Chrome 的开发人员工具控制台时，它们工作正常。然而，当我将它们放入 Selenium 中时，我收到“参数列表后缺少 )”错误。我知道这可能意味着问题可能是由于语法不正确造成的，但我不确定如何或为什么会出现这种情况。 请注意，这些尝试是单独完成的。

//Attempt 1
 JavascriptExecutor js = (JavascriptExecutor)driver;    
        js.executeScript( "var evt = document.createEvent('MouseEvent');" +
        "evt.initMouseEvent('mousedown', true, true, window, 0, 0, 0, 382, 290 , false, false, false, false, 0, null);" +
        "var cb = document.getElementById('gameCanvas');"+
        "cb.dispatchEvent(evt);"+
        "setTimeout(function(){"+
        "evt.initMouseEvent('mouseup', true, true, window, 0, 0, 0, 382, 290 false, false, false, false, 0, null);"+ 
        "cb.dispatchEvent(evt);}, 100); };"); 

//Attempt 2 
      JavascriptExecutor js = (JavascriptExecutor)driver;   
        js.executeScript( "var evt = document.createEvent('MouseEvent');" +
        "evt.initMouseEvent('mousedown', true, true, window, 0, 0, 0, 382, 290 , false, false, false, false, 0, null);" +
        "var cb = document.getElementById('gameCanvas');"+
        "cb.dispatchEvent(evt);"+
        "evt.initMouseEvent('mouseup', true, true, window, 0, 0, 0, 382, 290 false, false, false, false, 0, null);"+ 
        "cb.dispatchEvent(evt);"); 

Answer 1

In both of the attempts the second evt.initMouseEvent line lacks a comma between 290 and false. – Teemu 28 mins ago

还有一个额外的“};”在“100);”之后。
