我有一个包含 JavaScript 函数的 ASP.NET 页面，如下所示：
function PrintGridView(Title,Address,Terms,GridViewName) {
if (document.getElementById != null) {
var html = '<html xmlns="http://www.w3.org/1999/xhtml" dir="rtl" xml:lang="en"><HTML>\n\n';
html += '<head> <title>' + Title + '</title> <link href="Styles/Print.css" rel="stylesheet" type="text/css" /> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />';
html += "";
html += '</head>';
html += '<body> <div id="page-wrap">';
html += '<textarea id="header">'+Title+'</textarea>';
html += '<div id="identity">';
html += '<textarea id="address">'+Address+'</textarea>';
html += '<div id="logo">';
html += '<div id="logohelp">';
html +='<input id="imageloc" type="text" size="50" value="" /><br />';
html +='(max width: 540px, max height: 100px)';
html +='</div>';
html += '<img id="image" src="images/smallLogo.png" alt="logo" />';
html +='</div>';
html += '</div>';
html += '<div style="clear:both"></div>';
var tablerow = GridViewName.getElementsByTagName("tr");
html += '<table align="center" id="items">';
var td = tablerow.item(0).getElementsByTagName("th");
html += '<tr>'; // Get Table Header
for (var i = 1; i < td.length ; i++) {
html +='<th width=auto>'+td.item(i).innerText+'</th>';
}
html += '</tr>';
//Get Table Rows Data
if (tablerow.length > 10)
var Rowlen = 11;
else
var Rowlen = tablerow.length -1;
for (var j = 1; j < Rowlen; j++) {
html += '<tr class="item-row">';
var tRow= tablerow.item(j).getElementsByTagName("td");
for (var i = 1; i < 3; i++) {
html += '<td >' + tRow.item(i).innerText + '</td>';
}
html += '</tr>';
}
html += '</table>';
html += '<div id="terms"> <h5>notice</h5> <textarea>'+Terms+'</textarea></div>';
html +='</div></body></html>';
}
var printWin = window.open("", "PrintGridView");
printWin.document.open();
printWin.document.write(html);
printWin.document.close();
//printWin.print();
}

我尝试将 GridView ID 传递给声明如下的 JavaScript 函数：
'PrintGridView(Title,Address,Terms,GridViewName)'
在我的 ASP.NET 页面中将其用于ImageButtonon OnClientClickEvent 如下：
<asp:ImageButton ID="SendingDownTypePrintImageButton" runat="server" ImageUrl="~/images/printer.png" ToolTip="Print" OnClientClick="PrintGridView('university',' address','Terms','<%=SendingDownTypeGridView.ClientID%>')"/>
但我总是得到一个错误。我应该怎么做才能解决这个问题？
