Java HtmlUnit属性未定义脚本错误
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，我遇到了ScriptException错误。消息为“无法将未定义的属性“已禁用”设置为“0” 我认为这可能是由于javascript方法试图设置一个未在表单中声明的变量造成的，但我不确定Java HtmlUnit属性未定义脚本错误,java,javascript,html,Java,Javascript,Html,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，我遇到了ScriptException错误。消息为“无法将未定义的属性“已禁用”设置为“0” 我认为这可能是由于javascript方法试图设置一个未在表单中声明的变量造成的，但我不确定 tempForm = MyPage.getFormByName("menu_form"); tempForm.getInputByName("userId").setValueAttribute("myusername")

你能提供一个公共网站进行测试吗？因为我无法加载JS
另外，请使用最新的HtmlUnit 2.5版本。这是由于加载页面上的javascript错误造成的。 我设定了 webClient.getOptions（）.SetThroweExceptionOnScriptError（false） 但它仍然抛出了例外 解决方案：如果捕获到ScriptException，则页面仍处于完全加载状态，您可以继续处理并忽略异常 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>
JS测试
函数run_js（）
{
form.myinput.value=“从正文开始”；
//document.myform.myinput.value=“来自正文”；
}
身体。
