Submit not working in Chrome and IE under Windows 7
I have a web form created using .net and in this form has a frame which has its source from another HTML page (created by courselab software). I call a JavaScript code whenever the user completes the page and click a submit button and exits normally or whenever the user navigates away from the page based on the JavaScript event onbeforeunload.
The code works just perfectly using:
Firefox in both cases
IE on Windows XP in both casesStill it works in CHROME if the user clicked on the submit button (this submit button generated by courselab software which calls the JavaScript code),
but if the user navigates away from the web form, this code is being called using the onbeforeunload and the code renders correctly but the submit input is never fired.
Similarly this code does not fire using IE on Windows 7.
I have also called the code onunload of the form, but still nothing happens.
Update
IE 8 Firefox 3.6.1.3 Chrome 9.0.597.98The main web form has the following:
<div id="FOContent">
<iframe runat=server id="mainiframe" name="mainiframe" scrolling="no" frameborder="no"
width="1000" height="920"></iframe>
</div>
The frame content comes from this HTML page:
<body style="margin-left:0px;margin-top:0px;margin-right:0px;margin-bottom:0px;" onload="Run(true)" onunload="Shutdown()" onbeforeunload="Shutdown()" oncontextmenu="return false">
<div id="boardFrame" style="position:absolute;left:0px;top:0px;width:1000;height:700">
</div>
<div id="divEmail"></div>
</body>
And the JavaScript code being called for onunload or onbeforeunload is:
function LMSShutdown() {
if (submit_Var == false) {
var sAiccData = AICC_PrepareData(); // prepare data fr开发者_StackOverflow中文版om the CourseLab
var strQuizResults
strQuizResults = "";
var nPos1 = sAiccData.indexOf("Score=");
nPos1 = nPos1 + 6;
var ePos1 = nPos1 + 2
var score = sAiccData.substring(nPos1, ePos1);
var sHTML = "";
var qTxt;
qTxt = ""
var qrStr = window.location.search;
var spQrStr = qrStr.substring(1);
var arrQrStr = new Array();
// splits each of pair
var arr = spQrStr.split("&");
for (var i = 0; i < arr.length; i++) {
// splits each of field-value pair
var index = arr[i].indexOf("=");
var key = arr[i].substring(0, index);
var val = arr[i].substring(index + 1);
var id1
var id2
if (key == "")
{key = "Q"+i}
qTxt = qTxt + "&" + key + "=" + val;
if (i == 0)
{ id1 = val; }
else
{ id2 = val; }
}
// saves each of field-value pair in an array variable
sHTML += '<FORM id="formQuiz" method="POST" action="../../../StudentView/QuizProcess.aspx?submit_Var=' + 'false' + '&score=' + score + qTxt + '">';
var spQrStr = g_arVars["writing"];
var arrQrStr = new Array();
// splits each of pair
var arr = spQrStr.split("@@@");
for (var i = 0; i < arr.length; i++) {
// splits each of field-value pair
var index = arr[i].lastIndexOf(":");
var key = arr[i].substring(0, index);
var val = arr[i].substring(index + 1);
if (key != "")
{qTxt = qTxt + "&" + key + "=" + val;
sHTML += '<INPUT TYPE="hidden" NAME="' + key + '" VALUE=\'' + val + '\'>';
}
}
sHTML += '<br><input name="btnSubmit" id="btnSubmit" type="button"><br>';
sHTML += '</FORM>';
document.getElementById("divEmail").innerHTML = sHTML;
document.getElementById("formQuiz").submit();
submit_Var = true;
}
}
The QuizProcess.aspx page has not much in HTML, but it has vb .net code to store data to database
The issue is that the function LMSShutdown is being called in all browsers on different platforms, but the form QuizProcess is not being submitted only in (Chrome on Windows XP or 7 ) and in (IE 8 when using Windows 7) strangely works fine in IE 8 on Windows XP.
Sounds like a security restriction here. Try generating that form straight from ASP.NET instead of Javascript. This will help Chrome see it, as the will be in the raw html rather than virtual. Of course, all the 's to the form can be hidden, so it wont affect the presentation.
