增加一个显示更多的功能 附上代码:使用实例在附件
复制代码 代码如下:
jQuery.fn.extend({
limittext:function(opt){
opt=$.extend({
"limit":30,
"fill":"..."
},opt);
opt.morefn=$.extend({
"status": false,
"moretext": "(more)",
"lesstext":"(less)",
"cssclass": "limittextclass",
"lessfn": function(){
},
"fullfn": function(){
}
},opt.morefn);
var othis=this;
var $this=$(othis);
var body=$this.data('body');
if(body==null){
body=$this.html();
$this.data('body',body);
}
var getbuttom=function(showtext){
return "+opt.morefn.cssclass+"'>"
+showtext
+"";
}
this.limit=function(limit){
if(body.length<=limit||limit=='all'){
var showbody=body+(opt.morefn.status?getbuttom(opt.morefn.lesstext):"");
}else{
if(!opt.morefn.status){
var showbody=body.substring(0,limit)
+opt.fill;
}else{
var showbody=body.substring(0,limit)
+opt.fill
+getbuttom(opt.morefn.moretext);
}
}
$this.html(showbody);
}
this.limit(opt.limit);
$("."+opt.morefn.cssclass).live("click",function(){
if($(this).html()==opt.morefn.moretext){
showbody=body
+getbuttom(opt.morefn.lesstext);
$this.html(showbody);
opt.morefn.fullfn();
}else{
othis.limit(opt.limit);
opt.morefn.lessfn();
}
});
return this;
}
});
