鼠標移到控件上方提示幫助信息

1、創建一個*.js文件包含以下信息

//鼠標移到控件上方提示幫助信息
document.write("<div id=HelpMessageLayer style='border-right: #000000 1px ridge; border-top: #000000 1px ridge; border-left: #000000 1px ridge; color: #000033; border-bottom: #000000 1px ridge; font-family: Arial; font-size:13px; font-style: normal; font-variant: normal; text-decoration: none;background-color:#fff4e6;position: absolute; z-index: 99999999999999; display: none'>help Message!!</div>");

function MessageLayer() //初始化設置
{
    this.backImage = "";   //url(print.jpg);
    this.backColor = "#FFFFFF";
    this.objExport = null;
    this.layerOut   = document.all.HelpMessageLayer;
}

var MessageLayer = new MessageLayer();

function CSWITHiddenLayer()
{
MessageLayer.layerOut.style.display = "none";
}

function CSWITHelpMessageInfo() //主調函數
{
     var e = window.event.srcElement;
    MessageLayer.eventSrc = e;

var o = MessageLayer.layerOut.style;

MessageLayer.layerOut.innerText= arguments[1];

    if (arguments.length == 0)
    {
        MessageLayer.objExport = e;
    }
    else
    {
        MessageLayer.objExport = eval(arguments[0]);

    }

o.display = "";

o.top=window.event.y+16;
o.left=window.event.x+5;

}

2、在前臺用JavaScript調用

調用方式如

<input type="submit" name="btnAdd" value="新增" id="btnAdd" class="input" WITOwner="true" EnableFlag="0" onmouseover="CSWITGetHelpMessageInfo(this,'新增功能');CSWITURL_OnMouseOver(this,'#000000');" style="width:41px;" />
o.display = "";

o.top=window.event.y+16;
o.left=window.event.x+5;

}

注意: 粗體部分為調用的部分
