jquery实现股票涨跌效果

jQuery CSS JavaScript HTML IDEA

jquerystock.js:

//进入页面以后就显示股票当前的价格信息
var obj;
var sid;
$(document).ready(function(){
var stockNode = $("#stock").css("border","1px solid green").css("background","blue")
.css("color","red").css("width","150px").css("position","absolute"); //只有将Position属性定义为absolute才可以在想要的位置出现对话框
stockNode.hide();
getStockInfo();
//每隔一秒与服务器交互一次，页面自动刷新当前的股票价格信息
setInterval(getStockInfo,1000);
var as = $("a");
//定义鼠标划入的事件
as.mouseover(function(){

var aNode = $(this);
var divNode = aNode.parent();
sid = divNode.attr("id");
//updatediv();
//控制弹出框的位置
//1.查处链接的位置
var offset = aNode.offset();
//2.设置弹出框的位置
stockNode.css("left",offset.left + "px").css("top",offset.top + aNode.height() + "px");

stockNode.show();

});
//定义鼠标划出的事件
as.mouseout(function(){
stockNode.hide();
});

});

});

}

//更新显示框中的内容
function updatediv(){
var stockObj = obj[sid];
for(var prop in stockObj){
if(prop != "name"){
$("#"+ prop).children("span").html(stockObj[prop]);
}
}
}
