首先我需要说的是，我对JS没有太多的经验。目前我试图用MVC框架实现一个Web应用程序。我正在开发一款兼容Internet Explorer的应用程序。在这种情况下，我使用以下JS方法来填充该工作正常与所有的浏览器的表格....调用Array.length时出现未知错误
function populateTable(array) {
document.getElementById("instalationTable").style.display = "block";
var table = document.getElementById("ActivityDescription_installationID");
table.innerHTML = "";
elementsInTable = array;
var x = 0;
for (i = 0; i < (array.length * 2) ; i++) {
//alert(i);
if ((i % 2) == 0) {
//ID Row
var row = table.insertRow(i);
var cell_1 = row.insertCell(0);
cell_1.innerHTML = "<input type='text' disable='' class='form-control' value=" + array[x] + ">";
x = x + 1;
var cell_2 = row.insertCell(1);
cell_2.innerHTML = "<span class='btn btn-default' onclick='showEditRow(this)'><img src='../../Content/images/1414409386_48-24.png' /></span>";
var cell_3 = row.insertCell(2);
cell_3.innerHTML = "<span class='btn btn-default' onclick='removeRow(this)'>X</apan>";
}
else {
//Detail Row
var rowDetails = table.insertRow(i);
var cell = rowDetails.insertCell(0);
//cell.colspan = "3";
cell.innerHTML = "<table style='background-color:rgb(98, 98, 98);color:black;border- radius: 5px;' margin:2%; >" +
"<tr>" +
"<td><input type='checkbox' id='"+x+"_appServer'/> Application Server</span></td>" +
"<td>" +
"<select id='" + x + "_appServerVersion'>" +
"<option>Application version</option>" +
"</select>" +
"</td>" +
"</tr>" +
"<tr>" +
"<td colspan='2'><input type='radio' name='database' id='"+x+"_emptyDb' onChange='enableOptions(1)'/>" +
" Empty Database</br><input type='radio' name='database' id='" + x + "_instalationSlt' onChange='enableOptions(2)'/> Something Databse</td>" +
"</tr>" +
"<tr id='emptyDB'>" +
"<td>" +
"Oracle Version"+
"<select id='JS_OraVersion' name='" + x + "_oraVersion' style='width:100%'>" +
"<option>Ora version</option>" +
"</select>" +
"</td>" +
"<td>" +
"Character Set" +
"<select id='JS_ChaSet' name='" + x + "_ChaSet' style='width:100%'>" +
"<option>Cha Set</option>" +
"</select>" +
"</td>" +
"</tr>" +
"<tr id='dbImport'>" +
"<td>" +
"Something version" +
"<select id='JS_ImportVersion' name='" + x + "_ImportVersion' style='width:100%'>" +
"<option>Something version</option>" +
"</select>" +
"</td>" +
"<td>" +
"Something Charachter" +
"<select id='JS_ImportChaSet' name='" + x + "_ImportChaSet' style='width:100%'>" +
"<option>Something Cha</option>" +
"</select>" +
"</td>" +
"</tr>" +
"<tr>" +
"<td colspan='2'>" +
"Additional Requests </br>" +
"<textarea rows='4' id='" + x + "_specialReq' cols='37'> </textarea>" +
"<td/>"+
"</tr>"+
"</table>";
rowDetails.style.display = 'none';
Lock();
}
}
document.getElementById("instalationTable").style.display = "block";
}
我在上表中的行填充形式，收集一些数据以继续。收集我使用下面的函数数据的正常工作与谷歌Chrome，但不是与Internet Explorer ..
function getAllData() {
var StringtoSent = "";
for (i = 0; i < (elementsInTable.length) ; i++) {
var InsId = elementsInTable[i];
var _appServer = document.getElementById((i + 1) + "_appServer").checked;
var _appServerVersionDropDown = document.getElementById((i + 1) + "_appServerVersion");
var _appServerVersion = _appServerVersionDropDown.options[_appServerVersionDropDown.selectedIndex].value;
var _emptyDb = document.getElementById((i + 1) + "_emptyDb").checked;
var _instalationSlt = document.getElementById((i + 1) + "_instalationSlt").checked;
var _oraVersionDropDown = document.getElementsByName((i + 1) + "_oraVersion")[0];
var _oraVersion = _oraVersionDropDown.options[_oraVersionDropDown.selectedIndex].value;
var _ChaSetDropDown = document.getElementsByName((i + 1) + "_ChaSet")[0];
var _ChaSet = _ChaSetDropDown.options[_ChaSetDropDown.selectedIndex].value;
var _ImportVersionDropDown = document.getElementsByName((i + 1) + "_ImportVersion")[0];
var _ImportVersion = _ImportVersionDropDown.options[_ImportVersionDropDown.selectedIndex].value;
var _ImportChaSetDropDown = document.getElementsByName((i + 1) + "_ImportChaSet")[0];
var _ImportChaSet = _ImportChaSetDropDown.options[_ImportChaSetDropDown.selectedIndex].value;
var _specialReq = document.getElementById((i + 1) + "_specialReq").value;
StringtoSent = StringtoSent + "," + InsId + "," + _appServer + "," + _appServerVersion + "," + _emptyDb + "," + _instalationSlt + "," + _oraVersion + "," + _ChaSet + "," + _ImportVersion + "," + _ImportChaSet + "," + _specialReq + "|";
//return StringtoSent;
document.getElementById("ActivityDescription_instalationDetails").value = StringtoSent;
}
}
下图显示了即时得到当它在VS 2012S IIS搞坏了错误表现。 
for (i = 0; i < (elementsInTable.length) ; i++) {
是指示作为错误的地点。它总是突出显示“elementsInTable.length”代码段。
其实这个错误信息没有详细说明。我发现了一些关于相同错误的文章，但在尝试更改元素的内部HTML时发生。但是这些解决方案都没有出现这种情况兼容。请帮助我的问题
在此先感谢
哪条线是238 ...？ – 2014-10-30 10:26:34
我认为它在Chrome中无法正常工作。但VS与VS有联系，当出现错误时它会抛出一个异常。查看Chrome控制台。有没有相同的错误？ – 2014-10-30 10:28:25
for（i = 0; i <（elementsInTable.length）; i ++）{这是行抱歉!!!! – Sandaru 2014-10-30 10:46:39
