Element Object
Definition and Usage
The setAttribute() method adds a new attribute.
If an attribute with that name already exists in the element, its value is changed to be that of the value parameter
Syntax
elementNode.setAttribute(name,value)
| Parameter | Description |
|---|---|
| name | Required. Specifies the name of the attribute to set |
| value | Required. Specifies the value of the attribute to set |
Example
The following code fragment loads "books.xml" into xmlDoc using loadXMLDoc() and adds an "edition" attribute to all <book> elements:
Example
xmlDoc=loadXMLDoc("books.xml");
x=xmlDoc.getElementsByTagName("book");
for(i=0;i<x.length;i++)
{
x.item(i).setAttribute("edition","first");
}
//Output book title and edition value
x=xmlDoc.getElementsByTagName("title");
for (i=0;i<x.length;i++)
{
document.write(x[i].childNodes[0].nodeValue);
document.write(" - Edition: ");
document.write(x[i].parentNode.getAttribute('edition'));
document.write("
");
}
x=xmlDoc.getElementsByTagName("book");
for(i=0;i<x.length;i++)
{
x.item(i).setAttribute("edition","first");
}
//Output book title and edition value
x=xmlDoc.getElementsByTagName("title");
for (i=0;i<x.length;i++)
{
document.write(x[i].childNodes[0].nodeValue);
document.write(" - Edition: ");
document.write(x[i].parentNode.getAttribute('edition'));
document.write("

}
