提交在 Windows 7 下的 Chrome 和 IE 中不起作用

发布于 2024-10-17 07:10:17 字数 3401 浏览 2 评论 0原文

我有一个使用 .net 创建的 Web 表单，并且在此表单中有一个框架，该框架的源代码来自另一个 HTML 页面（由 courselab 软件创建）。每当用户完成页面并单击提交按钮并正常退出时，或者每当用户基于 javascript 事件“onbeforeunload”导航离开页面时，我都会调用 javascript 代码。

在这两种情况下，代码都可以完美地使用

Firefox *两种情况下 Windows XP 上的 IE*

如果用户单击提交按钮（此提交按钮由调用 javascript 代码的 courselab 软件生成），它仍然可以在 CHROME 中工作，

但是如果用户离开 Web 表单，则会使用“onbeforeunload”调用此代码，并且代码会正确呈现，但永远不会触发提交输入。

类似地，在 Windows 7 上使用 IE 也不会触发此代码。

我还调用了表单的代码“onunload”，但仍然没有任何反应。

更新浏览器8 火狐浏览器 3.6.1.3 Chrome 9.0.597.98

主要的 Web 表单具有以下内容

<div id="FOContent">
<iframe  runat=server id="mainiframe" name="mainiframe" scrolling="no" frameborder="no"
width="1000" height="920"></iframe>
</div>

框架内容来自此 HTML 页面

<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>

调用“onunload”或“onbeforeunload”的 javascript 代码是

function LMSShutdown() {
if (submit_Var == false) {
    var sAiccData = AICC_PrepareData();  // prepare data from 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;
}
}

QuizProcess.aspx 页面的 HTML 内容不多，但有 vb 。 net 代码将数据存储到数据库

问题是，在不同平台上的所有浏览器中都调用了函数 LMSShutdown，但表单 QuizProcess 并未仅在（Windows XP 或 7 上的 chrome）和（使用 Windows 时的 IE 8）中提交7) 奇怪的是，在 Windows XP 上的 IE 8 中运行良好。

原文

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 cases*

Still 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.

Similary 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 9.0.597.98

the 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 from 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.
