效果1. 当鼠标放在某日上时，如果当天有备忘录，则会显示出来，如下图：

function checkfortasks (thedate, e){ 
//找到页面中taskbox对应<div>设置为可见 
theObject = document.getElementById("taskbox"); 
theObject.style.visibility = "visible"; 
//初始化taskbox位置 
var posx = 0; 
var posy = 0; 
//定位taskbox位置为鼠标位置 
posx = e.clientX + document.body.scrollLeft; 
posy = e.clientY + document.body.scrollTop; 
theObject.style.left = posx + "px"; 
theObject.style.top = posy + "px"; 
//设置PHP请求页面 
serverPage = "taskchecker.php?thedate=" + thedate; 
//设置PHP返回数据替换位置 
objID = "taskbox"; 
var obj = document.getElementById(objID); 
//发送请求并加载返回数据 
xmlhttp.open("GET", serverPage); 
xmlhttp.onreadystatechange = function(){ 
if (xmlhttp.readyState == 4 && xmlhttp.status == 200){ 
obj.innerHTML = xmlhttp.responseText; 
} 
} 
xmlhttp.send(null); 
} 

效果2. 当鼠标点击某日录入姓名时，系统会自动检索姓名是否存在，并可以通过选择填入姓名框中，如图：

function autocomplete (thevalue, e){ 
//定位页面中autocompletediv（显示检索姓名的标签）的<div>位置 
theObject = document.getElementById("autocompletediv"); 
//设置为可见 
theObject.style.visibility = "visible"; 
theObject.style.width = "152px"; 
//设置检索标签位置 
var posx = 0; 
var posy = 0; 

posx = (findPosX (document.getElementById("yourname")) + 1); 
posy = (findPosY (document.getElementById("yourname")) + 23); 

theObject.style.left = posx + "px"; 
theObject.style.top = posy + "px"; 
//设定事件为键盘录入 
var theextrachar = e.which; 

if (theextrachar == undefined){ 
theextrachar = e.keyCode; 
} 
//设定加载检索名单位置 
var objID = "autocompletediv"; 

//设定PHP请求页面，并将用户输入的姓名传值过去（同时考虑到Backspace作用） 
if (theextrachar == 8){ 
if (thevalue.length == 1){ 
    var serverPage = "autocomp.php"; 
} 
else{ 
    var serverPage = "autocomp.php" + "?sstring=" + thevalue.substr(0, (thevalue.length -1)); 
} 
} 
else{ 
var serverPage = "autocomp.php" + "?sstring=" + thevalue + String.fromCharCode(theextrachar); 
} 
//发送请求并加载返回数据 
var obj = document.getElementById(objID); 
xmlhttp.open("GET", serverPage); 
xmlhttp.onreadystatechange = function() { 
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) { 
    obj.innerHTML = xmlhttp.responseText; 
} 
} 
xmlhttp.send(null); 
}
