在HTM页面中，我使用javascript从XML文件中获取数据并将其放入htm页面。
当用户点击图书图片时，会打开一个窗口，其中显示一个"添加到购物车"的按钮
然而，'onclick图片上的"事件"应该发送图书名称的参数。我得到这个工作，除非我每次点击图书图像，即使我点击第一本和第二本书，最后一本书的名称也作为参数传递。
你怎么能纠正这个<这是htm页面中的Javascript。
< script language ="的JavaScript" type =" text / javascript">

Within an HTM page i use javascript to get the data from the XML file and place it into the htm page.
When the use clicks on the book image a window opens with a button that says 'add to cart'
However, the 'onclick event' on the picture should send a parameter of the book name. i get this to work except that every time i click the book image the last book name is passed as a parameters even if i click the first and second book.
How can you correct this
here is the Javascript in the htm page.
<script language="JavaScript" type="text/javascript">
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.open("GET","bookCatalogue.xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
var t = 0;
x=xmlDoc.getElementsByTagName("book")
var bookArr=new Array();
for (var i = 0; i < x.length; i++)
{
for (var j = 1; j < x[i].childNodes.length; j++)
{
//this gets the names of the books
var currentNode = x[i].childNodes[3];
var a = currentNode.firstChild.nodeValue;
//this gets all the other node data i.e. jpeg,price,name,description
var Nnode = x[i].childNodes[j];
var t = Nnode.firstChild.nodeValue;
if (j == 1)
{
///this gets the image of the book with the onclick event storing the name of the book
document.write ("<img src= '../img/" + t + "' border='0' onclick ='showDetails(a)'/> <br>");
}
else
{
document.write ("<p>" + t + "<p>");
}
j++;
}
document.write ("<br><br>");
}
function showDetails(name)
{
alert(name);
var bookURL = "pro_asp_details.htm";
detailsWindow = window.open(bookURL,"bookDetails","width=400,height=350");
}
</script>
document.write ("<img src= '../img/" + t + "' border='0' onclick ='showDetails(\""+a+"\")'/> <br>");
