1.回車控制
var keyc=window.event.keyCode;
if(keyc==13)
{
//自己的操作
}
2.獲得與數據庫一樣格式的時間串
function nowTime()
{
var now=new Date();
var timeStr=now.getYear()+"-";
if(now.getMonth()<9)
{
timeStr += "0"
timeStr += now.getMonth()+1+"-";
}else
{
timeStr += now.getMonth()+1+"-";
}
if(now.getDate()<10)
{
timeStr +="0"+now.getDate();
}else
{
timeStr += now.getDate();
}
if(now.getHours()-0<10)
{
timeStr +=" 0"+now.getHours();
}else
{
timeStr +=" "+now.getHours();
}
if(now.getMinutes()-0<10)
{
timeStr +=":0"+now.getMinutes();
}else
{
timeStr +=":"+now.getMinutes();
}
if(now.getSeconds()-0<10)
{
timeStr +=":0"+now.getSeconds()
}else
{
timeStr +=":"+now.getSeconds()
}
return timeStr;
}
3.全屏局中open
window.open("<c:url value='/"+url_+"'/>","","toolbar=0,location=0,scrollbars=1,resizable=1,width="+(screen.availWidth-20)+",height="+(screen.availHeight-30)+",top=0,left=0")
4.js對文字進行編碼涉及3個函數:escape,encodeURI,encodeURIComponent,
相應3個解碼數:unescape,decodeURI,decodeURIComponent
5.獲得js對象的內容
var aaaa;
for(var a in obj)
{
aaaa+=a+" : "+json[a]+"<br/>"
}
//document.write(aaaa);
//alert(aaaa);
6.iframe 內 調用外部方法 和 iframe外 調用iframe內的
//iframe中
window.parent.myMethod();
//iframe中
window.parent.setIframeDom(window);
//iframe外
var iframeObj;
function setIframeDom(obj)
{
iframeObj=obj;
}
//例子
function exportToExcelO()
{
iframeObj.exportToExcel();
}
