<div>在HTML中，某些字符是预留的(比如<或>)。如果希望正确显示预留字符，那么就必须使用字符实体。<br/>
字符实体类似这样: &entity_name;或者&#entity_number;<br/>
实体名记忆方便，而实体数字的支持性比较好，格式分别是&{content};和&#{content};<br/>
即：以&或&#开头并以;结尾。</p></div>
<script type="text/javascript">
for(var i=1; i<=40000; i+=2000)
	document.write('<input type="button" value="'+i+'-'+(i+1999)+'" onclick="bb('+i+','+(i+1999)+')" />');
function bb(a,b)
{
	var s = a+"-"+b+"<br />";
	for(var i=a; i<=b; i++)
	{
		s += '<span title="'+i+'\n'+i.toString(16)+'">&#'+i+';</span>';
		if(i%15==0)
			s += '<br />';
	}
	document.getElementById("dd").innerHTML = s;
}

<div id="dd"></div>
