Method ya XML DOM appendChild()

Mfano wa Node

Maelezo na Matumizi

appendChild() Method inasaidia kuongeza kina kipya kwenye orodha ya kina kwenye mabonde ya kina.

Hataraji:Ikiwa newchild Inafikia katika mabonde, tena inasifungua kwanza.

Inasemekana

nodeObject.appendChild(newchild)

Mifano

Mwongozo 1

Makini ya kipindi hiki kinahusisha kusimamia "books.xml" kwenye xmlDoc, na kumuea kina (<edition>) kwenye kina kidogo cha kwanza cha <book> kisha kuihifadhi kwenye kina kidogo cha kwanza cha <book>:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
   if (this.readyState == 4 && this.status == 200) {
       myFunction(this);
   }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
    var xmlDoc = xml.responseXML;
    var newel = xmlDoc.createElement("edition");
    var x = xmlDoc.getElementsByTagName("book")[0];
    x.appendChild(newel);
    document.getElementById("demo").innerHTML =
    x.getElementsByTagName("edition")[0].nodeName;
}

Example 2

Append child nodes to all <book> nodes:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
        myFunction(this);
    }
};
xhttp.open("GET", "books.xml", true);
xhttp.send();
function myFunction(xml) {
    var x, y, z, i, xLen, yLen, newEle, newText, xmlDoc, txt;
    xmlDoc = xml.responseXML;
    txt = "";
    x = xmlDoc.getElementsByTagName("book");
    xLen = x.length;
    for (i = 0; i < xLen; i++) { 
        newEle = xmlDoc.createElement("edition");
        newText = xmlDoc.createTextNode("first");
        newEle.appendChild(newText);
        x[i].appendChild(newEle);
    }
    // Output all title and edition
    y = xmlDoc.getElementsByTagName("title");
    yLen = y.length
    z = xmlDoc.getElementsByTagName("edition");
    for (i = 0; i < yLen; i++) { 
        txt += y[i].childNodes[0].nodeValue + 
        " - Edition: " + 
        z[i].childNodes[0].nodeValue + "<br>";
    }
    document.getElementById("demo").innerHTML = txt; 
}
