解决非IE无法使用innerText问题
function isIE(){ //判断是否是ie if (window.navigator.userAgent.toString().toLowerCase().indexOf("msie") >=1) return true; else return false;}if(!isIE()){ //firefox innerText define HTMLElement.prototype.__defineGetter__( "innerText", function(){ var anyString = ""; var childS = this.childNodes; for(var i=0; i <childS.length; i++) { if(childS[i].nodeType==1) anyString += childS[i].tagName=="BR" ? '\n' : childS[i].innerText; else if(childS[i].nodeType==3) anyString += childS[i].nodeValue; } return anyString; } ); HTMLElement.prototype.__defineSetter__( "innerText", function(sText){ this.textContent=sText; } ); } ??
