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：
<A href="/upload/2009-11/20091124221629523.png">
<div class="codetitle"><a style="CURSOR: pointer" data="4114" class="copybut" id="copybut4114" onclick="doCopy('code4114')"> 代码如下:<div class="codebody" id="code4114">
function checkfortasks (thedate,e){
//找到页面中taskbox对应设置为可见
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：
<A href="/upload/2009-11/20091124221629982.png">
<div class="codetitle"><a style="CURSOR: pointer" data="95828" class="copybut" id="copybut95828" onclick="doCopy('code95828')"> 代码如下:<div class="codebody" id="code95828">
function autocomplete (thevalue,e){
//定位页面中autocompletediv（显示检索姓名的标签）的位置
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);
}
