Question

我正在使用java HtmlUnit包提交表单。我能够获取页面并提交表单但在一个页面上我收到ScriptException错误。消息“未设置属性”已禁用“未定义为”0“”

我认为这可能是由于javascript方法试图设置一个尚未在表单中声明但我不确定的变量。

tempForm = MyPage.getFormByName("menu_form");
tempForm.getInputByName("userId").setValueAttribute("myusername");
HtmlPage editSubscriberPage = (HtmlPage)
tempForm.getInputByName("submit_button").click();



EcmaError: lineNumber=[824] column=[0] lineSource=[null] name=[TypeError] sourceName=[script in https://labserver.comp.com/mcwebadm/cgi-bin/edit_local.pl?operation=edit&return_address=%2Fmcwebadm%2Fcgi-bin%2Fmenu.pl&selected=2322020c341b11de96c3000423d43f1d from (9, 32) to (840, 15)] message=[TypeError: Cannot set property "disabled" of undefined to "0" (script in https://myserver.company.com/mcwebadm/cgi-bin/edit_local.pl?operation=edit&return_address=%2Fmcwebadm%2Fcgi-bin%2Fmenu.pl&selected=22020c341b11de96c3000423d43f1d from (9, 32) to (840, 15)#824)]

Answer 1

这导致我在正在加载的页面上出现javascript错误。

webClient.getOptions（）setThrowExceptionOnScriptError（假）;

但它仍然抛出异常。

解决方案：如果您捕获ScriptException，页面仍然是STILL完全加载，您可以继续处理并忽略该异常。

失败的HTML示例：

<html>
<Head><title>JS Test</title>
    <script type="text/javascript">
        function run_js()
        {
                form.myinput.value = "from on body";
//              document.myform.myinput.value = "from body";
        }
        </script>   
    </head>

<body onload="run_js()">
    The Body.
    <form name="myform">
        <input name="myinput" type="text"/>
    </form>
</body>
</html>

Answer 2

您可以提供一个公共网站进行测试吗？因为我无法在https://mmlab1msslnx.fmr.com/mcwebadm/cgi-bin/edit_local.pl?operation=edit&return_address=%2Fmcwebadm%2Fcgi-bin%2Fmenu.pl&selected=22020c341b11de96c3000423d43f1d

中加载JS

另外，请使用最新的HtmlUnit 2.5版本。
