Question

这是我的javascript代码。

function getXmlData(){
        var icode=document.getElementById("itemcodee").value;
        alert(icode);
        var Connect = new XMLHttpRequest();
        // Define which file to open and
        // send the request.
        Connect.open("GET", "assets/itemdetail.xml", false);
        Connect.setRequestHeader("Content-Type", "text/xml");
        Connect.send(null);
        // Place the response in an XML document.
        var TheDocument = Connect.responseXML;
        // Place the root node in an element.
        var items = TheDocument.childNodes[0];
        // Retrieve each item in turn.
        for (var i = 0; i < items.children.length; i++)
        {
            var item = items.children[i];
            if(item==icode)
            {
                // Access each of the data values.
                var code = item.getElementsByTagName("code");
                var name = item.getElementsByTagName("name");
                var stock = item.getElementsByTagName("stock");
                // print these values to corresponding field
                document.getElementById("itemnamee").value=name;
                document.getElementById("itemstock").value=stock;
                alert(code+'|'+name+'|'+stock)
            }
            else
            {
                alert('Sorry, Item Not Found. Please check the inventory');
            }
}
}

这是我的xml

    <?xml version="1.0" encoding="UTF-8"?>
    <xml>
<item><code>1</code><name>Sample Item</name><stock>0</stock></item>
<item><code>3</code><name>ITEM</name><stock>205000</stock></item>
<item><code>4</code><name>ABHI UPDATED</name><stock>2201</stock></item>
<item><code>5</code><name>Item 5</name><stock>10</stock></item>
<item><code>6</code><name>item 6</name><stock>2130</stock></item>
<item><code>7</code><name>Soap</name><stock>100</stock></item>
<item><code>8</code><name>New Item</name><stock>1201</stock></item>
</xml>

当我输入数据（此处为icode）时，我希望脚本从此xml文件中读取相关数据并将其显示在相应的texbox上。我坚持了很长时间。我尝试了各种解决方案，但仍然没有运气。

Answer 1

试试这个

var item = items.children[i];
var theCode = item.getElementsByTagName("code").html;
if(theCode==icode)
{
...
} else {
...
}

我无法将此xml文件读取到我的页面。该函数有效，但不读取xml
