但是，如果您看一下源代码，它会有很多凌乱的CSS代码。有没有办法我可以用Javascript做到这一点？
先谢谢了！

最佳答案

这是您只用HTML编写的一种方式：

<div id="wrap" >
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Vestibulum sollicitudin, felis nec lacinia egestas, metus sem tempor ligula, nec feugiat risus erat a ante. Vivamus a neque eu lorem pharetra vulputate ac id arcu. Nulla facilisi. Quisque porta purus id dolor sollicitudin ut interdum eros bibendum. Nunc dignissim velit vitae leo posuere vel tristique lacus bibendum. Nam suscipit elit magna. Cras odio ipsum, ultricies aliquet lacinia ac, tincidunt ut erat. In venenatis interdum mauris, a lobortis augue mattis vel. Donec sem urna, adipiscing laoreet consectetur nec, sodales id nibh. Integer gravida sem luctus nibh luctus tristique. In tempor adipiscing nisl. Proin consectetur, lorem eget sodales auctor, nulla quam condimentum tortor, sed fringilla massa neque non dolor.
</div>

JS：

var elem=document.getElementById("wrap");
var l=elem.innerHTML.length;
var newAns="";
for(var a=0;a<l;a++)
{
    newAns+='<span onmouseover="change1(this)" onmouseout="change2(this)" >'+elem.innerHTML.charAt(a)+'</span>';
}
elem.innerHTML=newAns;

function change1(x)
{
    x.style.color="yellow";
}
function change2(x)
{
    x.style.color="black";
}
