DOM - Node Object Attribute - firstChild
The attribute firstChild specifies the first child of a node.
Syntax
Following is the syntax for the usage of the firstChild attribute.
nodeObject.firstChild
Example
node.xml contents are as below −
<?xml version = "1.0"?> <Company> <Employee category = "Technical"> <FirstName>Tanmay</FirstName> <LastName>Patil</LastName> <ContactNo>1234567890</ContactNo> <Email>tanmaypatil@xyz.com</Email> </Employee> <Employee category = "Non-Technical"> <FirstName>Taniya</FirstName> <LastName>Mishra</LastName> <ContactNo>1234667898</ContactNo> <Email>taniyamishra@xyz.com</Email> </Employee> <Employee category = "Management"> <FirstName>Tanisha</FirstName> <LastName>Sharma</LastName> <ContactNo>1234562350</ContactNo> <Email>tanishasharma@xyz.com</Email> </Employee> </Company>
Following example demonstrates the usage of the firstChild attribute −
<!DOCTYPE html> <html> <body> <script> if (window.XMLHttpRequest) { xmlhttp = new XMLHttpRequest(); } else { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.open("GET","/dom/node.xml",false); xmlhttp.send(); xmlDoc = xmlhttp.responseXML; function get_firstChild(p) { a = p.firstChild; while (a.nodeType!=1) { a = a.nextSibling; } return a; } x = get_firstChild(xmlDoc.getElementsByTagName("Employee")[0]); document.write("First child is : "); document.write(x.nodeName); </script> </body> </html>
Execution
Save this file as nodeattribute_firstchild.htm on the server path (this file and node.xml should be on the same path in your server). We will get the output as shown below −
First child is : FirstName
dom_node_object.htm
