javascript가 크롬, 파이어 폭스와 같은 브라우저에서 작동하지 않습니다.

Question

경,

인터넷에서 다운로드 한 Javascript calendar (날짜 선택)가 있습니다. IE 6 버전에서 작업 할 때 적절한 날짜를 선택할 수 있습니다. 그러나 Google 크롬과 같은 현대적인 브라우저를 사용할 때 날짜를 선택할 수 없습니다 (클릭 작동하지 않음). 다음은 코드 단편입니다. 좋은 조언!

와우, new Function()? 정말?

td.onmouseover = function() {highLiteDay(this);}; 
td.onmouseout = function() {deHighLiteDay(this);}; 
// the above two should probably just be `:hover` styles in CSS 

(function(year,month,d) { 
    td.onclick = function() {pickDate(year, month, d);}; 
})(year,month,d); 
// this creates a closure to "anchor" the values of the variables 
// even as the loop iterates
