首先，看下效果图：
json字符串：
var mcode={"minfo":[{"time":"9:00-10:00","status":2},{"time":"10:00-11:00","status":1},{"time":"11:00-12:00","status":3},{"time":"13:00-14:00","status":1},{"time":"14:00-15:00","status":1},{"time":"15:00-16:00","status":1},{"time":"16:00-17:00","status":1},{"time":"17:00-18:00","status":1}]};
其中time代表时间段，status当职位1时代表可以使用，2时代表已过期，3时代表已选满。
通过循环遍历json字符串中的数据值。
for(var i in mcode.minfo){ mcode.minfo[i].time + mcode.minfo[i].status; }
当前时间段为已过期或以选满时，鼠标移动到其当前时间段上时提示相应信息，鼠标移开取消提示。
当前时间段为橘黄色代表可以选择。
$.each($("#test span"),function(k,v){
if($(this).hasClass("unspan1")||$(this).hasClass("unspan2")){
$(this).hover(function(){
$(this).find("label").css({"display":"block"});
$(this).find("em").css({"display":"block"});
}, function(){
$(this).find("label").css({"display":"none"});
$(this).find("em").css({"display":"none"});
});
}
else{
$(this).click(function(){
$("#result").empty().html("您选择了："+$(this).text());
});
}
});
拼接字符串，构建html结构。
for(var i in mcode.minfo){ if(mcode.minfo[i].status===2){ html+='<span class="unspan1 '; } else if(mcode.minfo[i].status===3){ html+='<span class="unspan2 '; } else{ html+='<span class=" '; } if((i+1)%3===0){ html+='" >'; } else{ html+='mspan" >'; } html+=mcode.minfo[i].time; if(mcode.minfo[i].status===2){ html+='<label>已过期</label>'; } else if(mcode.minfo[i].status===3){ html+='<label>已选满</label>'; } if(mcode.minfo[i].status!==1){ html+='<em></em>'; } html+="</span>"; }
css样式：
#test{ width: 430px; padding: 35px; border: 1px solid #666666;overflow: hidden; margin: 100px auto 0px;} #test span{display:block; background: #FF6600; width:130px; height: 30px; line-height: 30px; text-align: center; float:left;
