Param	Description
textstring	the required text e.g. 'added text'

Examples

// create a new paragraph
newpara = document.createElement("p");
// now some text
sometext = document.createTextNode("what a way to spend a life");
// stick them onto an existing object
existingobject = document.getElementById("one");
existingobject.appendChild(newpara);
existingobject.appendChild(sometext);

We create an empty paragraph newpara element and some text sometext and appends them (in the order shown) onto the existingobject which has id="one".

Notes:

createTextNode creates a single instance of the text which can only be used once.

// this code will NOT give desired results
// create a text node
// note: snippet assumes obj1 and obj2 are known to be para nodes
sometext = document.createTextNode("what a way to spend a life");
// stick same text onto existing objects - DOES NOT WORK
obj1 = document.getElementById("one");
obj2 = document.getElementById("two");
obj1.appendChild(sometext);
obj2.appendChild(sometext);

// this code WILL give desired results
// note: snippet assumes obj1 and obj2 are known to be para nodes
// now create text
sometext = document.createTextNode("what a way to spend a life");
// add text onto existing objects
obj1 = document.getElementById("one");
obj2 = document.getElementById("two");
// add first instance to obj1
obj1.appendChild(sometext);
// create a new instance an add to obj2
sometext = document.createTextNode("what a way to spend a life");
obj2.appendChild(sametext);
