I’m submitting a form using java HtmlUnit package. I am able to get pages and submit forms but on one page I’m getting a ScriptException error. The message is “Cannot set property "disabled" of undefined to "0"”

I think it might be caused by a javascript method that tries to set a variable that has not been declared in the form but I’m not sure.

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

Reset to default 3

This was caused my a javascript error on the page that was being loaded. I set the

webClient.getOptions().setThrowExceptionOnScriptError(false);

but it still threw the exception.

SOLUTION: If you catch the ScriptException the page is STILL fully loaded and you can just continue processing and ignoring the exception.

Example of HTML that fails:

<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>

Can you provide a public website to test against? As I am not able to load the JS in https://mmlab1msslnx.fmr./mcwebadm/cgi-bin/edit_local.pl?operation=edit&return_address=%2Fmcwebadm%2Fcgi-bin%2Fmenu.pl&selected=22020c341b11de96c3000423d43f1d

Also, please use latest HtmlUnit 2.5 version.
