嗨,我正在尝试使用 DOM 文档将 xml 数据从 php 获取到 javascript,它一直给我:XML or text declaration not at start of entity error .(on firebug) 我尝试将它保存到一个真正的 xml 文件并输出格式良好的 xml。
我猜这是因为 xml 文件顶部的空白。我尝试使用 ob_start(); 和 ob_end_flush(); 但无法得到那个工作顺便说一句我是 Ajax 的新手!
JS脚本
var xh = createRequest();
var xhrObject = false;
if (window.XMLHttpRequest)
{
xHRObject = new XMLHttpRequest();
}
else if (window.ActiveXObject)
{
xHRObject = new ActiveXObject("Microsoft.XMLHTTP");
}
function getData()
{
if ((xh.readyState == 4) &&(xh.status == 200))
{
alert("hi");
var serverResponse = xh.responseXML;
var header = serverResponse.getElementsByTagName("good");
var spantag = document.getElementById("sp");
var x;
spantag.innerHTML = "";
x = "<table cellpadding='1' cellspacing='6' border='0'>";
x += "<tr><td>ID</td><td>price</td><td>quantity</td><td>Total</td><td>Remove</td></tr>";
for (i=0; i<header.length; i++)
{
var id = header[i].getElementsByTagName("ID")[0].childNodes[0].nodeValue;
var price = header[i].getElementsByTagName("price")[0].childNodes[0].nodeValue;
var qty = header[i].getElementsByTagName("quantity")[0].childNodes[0].nodeValue;
var total = header[i].getElementsByTagName("total")[0].childNodes[0].nodeValue;
if(qty=="0")
{
continue;
}
x += "<tr>"
+ "<td>" + id + "</td>"
+ "<td>" + price + "</td>"
+ "<td>" + qty + "</td>"
+ "<td>" + total + "</td>"
+ "<td>" + "<a href='#' onclick='AddRemoveItem(\"Remove\","+id+");'>Remove Item</a>" + "</td>"
+ "</tr>";
}
x += "</table>";
if (header.length != 0)
spantag.innerHTML = x;
}
}
PHP code
function toXml($shop_goods)
{
$doc = new DomDocument();
$goods = $doc->createElement('goods');
$goods = $doc->appendChild($goods);
foreach ($shop_goods as $Item => $ItemName)
{
$good = $doc->createElement('good');
$good = $goods->appendChild($good);
$title = $doc->createElement('ID');
$title = $good->appendChild($title);
$value = $doc->createTextNode($Item);
$value = $title->appendChild($value);
$price = $doc->createElement('price');
$price = $good->appendChild($price);
$value3 = $doc->createTextNode($ItemName["price"]);
$value3 = $price->appendChild($value3);
$quantity = $doc->createElement('quantity');
$quantity = $good->appendChild($quantity);
$value2 = $doc->createTextNode($ItemName["qty"]);
$value2 = $quantity->appendChild($value2);
$total = $doc->createElement('total');
$total = $good->appendChild($total);
$value3 = $doc->createTextNode($ItemName["total"]);
$value3 = $total->appendChild($value3);
}
$strXml = $doc->saveXML();
//echo("<br>----- DATA RECOREDED!!! ----");
return $strXml;
}
