我有以下代码用于显示更多/更少，效果很好，但我想将作为 var moreText 和 lessText 一部分的文本“-”“+”替换为图形版本。任何帮助，将不胜感激。

查询：

<script type="text/javascript">
$(function(){

// The height of the content block when it's not expanded
var adjustheight = 85;
// The "more" link text
var moreText = "+ Read More"; 
// The "less" link text
var lessText = "- Read Less";

// Sets the .more-block div to the specified height and hides any content that overflows
$(".more-less .more-block").css('height', adjustheight).css('overflow', 'hidden');

// The section added to the bottom of the "more-less" div

$(".more-less").append('<a href="#" class="adjust"></a>');

$("a.adjust").text(moreText);

$(".adjust").toggle(function() {
    $(this).parents("div:first").find(".more-block").css('height', 'auto').css('overflow', 'visible')

        $(this).text(lessText);
}, function() {
    $(this).parents("div:first").find(".more-block").css('height', adjustheight).css('overflow', 'hidden')
    ;

    $(this).text(moreText);     
});

});

</script>

CSS：

.more-block p {
    font-family:Tahoma, Geneva, sans-serif; 
    font-size:14px; 
    line-height:22px;
    margin-bottom:20px;
    margin-top:0px;
}



a.adjust{

display:block;
font-weight:bold;
color:#333;
text-align:left;
text-decoration:none;
margin-top:20px;
padding-top: 10px;
padding-right: 10px;
padding-bottom: 10px;
width: 150px;
}


.more-less {
width: 300px;
}

HTML：

<div class="more-less">

    <div class="more-block">
      <p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat.

Typi non habent claritatem insitam; est usus legentis in iis qui facit eorum claritatem. Investigationes demonstraverunt lectores legere me lius quod ii legunt saepius. Claritas est etiam processus dynamicus, qui sequitur mutationem consuetudium lectorum. Mirum est notare quam littera gothica, quam nunc putamus parum claram, anteposuerit litterarum formas humanitatis per seacula quarta decima et quinta decima. Eodem modo typi, qui nunc nobis videntur parum clari, fiant sollemnes in futurum.</p>
    </div>

看起来你正在使用 JQuery 所以......

做这个：

var moreText = "<img src='plus.gif'/> Read More"; 
// The "less" link text
var lessText = "<img src='minus.gif'/> Read Less";

然后做这个：

$("a.adjust").html(moreText);

$(".adjust").toggle(function() {
    $(this).parents("div:first").find(".more-block").css('height', 'auto').css('overflow', 'visible')

        $(this).html(lessText);
}, function() {
    $(this).parents("div:first").find(".more-block").css('height', adjustheight).css('overflow', 'hidden')
    ;

    $(this).html(moreText);     
});
