Javascript 代碼：

復(fù)制代碼代碼如下:

 
//打開彈窗 
function f_OpenDialog() { 
var sHTML = '<p><input id="txtFile" type="file" /></p>' + 
'<p><input id="btnYes" type="button" onclick="f_ReadExcel();" value="確定">' + 
'<button id="btnNo" onclick="window.neatDialog.close();">取消</button></p>'; 
new NeatDialog(sHTML, "請選擇Excel文檔!"); 
} 
//關(guān)閉并移除彈窗 
NeatDialog.prototype.close = function () { 
if (this.elt) { 
this.elt.style.display = "none"; 
this.elt.parentNode.removeChild(this.elt); 
} 
window.neatDialog = null; 
} 
//創(chuàng)建彈窗 
function NeatDialog(sHTML, sTitle) { 
window.neatDialog = null;

if (document.createElement && document.getElementById) { 
var dg = document.createElement("div");
