[JavaScript]“种类不一致”错误
能够正常运行，但是总是页面总是有错误： 种类不一致。
没有baidu到解决方法。
csdn上有篇类似的帖子，但似乎不是一回事。
哪位兄弟给看看下面的代码到底有什么问题。
谢谢！！
P.S. 程序可以直接运行。
<html id= "html ">
<head id= "head ">
<title id= "title "> Introduction to the DOM </title>
<script id= "script ">
function test(){
append( document.getElementsByTagName( "ol ")[0], " <li> Mouse trap. </li> " );
}
//Enhanced Functions for Inserting and Appending into the DOM
function before( parent, before, elem ) {
// Check to see if no parent node was provided
if ( elem == null ) {
elem = before;
before = parent;
parent = before.parentNode;
}
// Get the new array of elements
var elems = checkElem( elem );
// Move through the array backwards,
// because we 're prepending elements
for ( var i = elems.length - 1; i > = 0; i-- ) {
parent.insertBefore( elems[i], before );
}
}
function append( parent, elem ) {
// Get the array of elements
var elems = checkElem( elem );
// Append them all to the element
for ( var i = 0; i <= elems.length; i++ ) {
parent.appendChild( elems[i] );
}
}
//Converting an Array of Mixed DOM Node/HTML String Arguments into a
//Pure Array of DOM Nodes
function checkElem(a) {
var r = [];
// Force the argument into an array, if it isn 't already
if ( a.constructor != Array ) a = [ a ];
for ( var i = 0; i < a.length; i++ ) {
// If there 's a String
if ( a[i].constructor == String ) {
// Create a temporary element to house the HTML
var div = document.createElement( "div ");
// Inject the HTML, to convert it into a DOM structure
div.innerHTML = a[i];
// Extract the DOM structure back out of the temp DIV
for ( var j = 0; j < div.childNodes.length; j++ )
r[r.length] = div.childNodes[j];
} else if ( a[i].length ) { // If it 's an array
// Assume that it 's &n
