示例
以下代码片段将
"books.xml" 加载到 xmlDoc 中,并将第一个<title>元素中文本节点的前八个字符替换为 “Easy”:
<!DOCTYPE html>
<html>
<body>
<p id="demo"></p>
<script>
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
myFunction(xhttp);
}
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
var xmlDoc = xml.responseXML;
var x = xmlDoc.getElementsByTagName("title")[0].childNodes[0];
document.getElementById("demo").innerHTML =
x.nodeValue;
x.replaceData(0, 8, "Easy");
document.getElementById("demo").innerHTML +=
"<br>" + x.nodeValue;
}
</script>
</body>
</html>
