重寫了JS代碼后上下調整的箭頭不顯示，我在href引用了CSS庫，是不是在調用change屬性的時候代碼有誤，請高手幫忙看看?$(function?()?{?????? ????????$("input").spinner({ ????????????max:?10, ???? ????min:?0, ???? ????step:?1, ???? ????spin:function(event,ui){ ???? if(ui.value==8){ ???? spnPrev.style.backgroundColor?=?"red"; ???? else ???? spnPrev.style.backgroundColor?=?"blue"; ???? ???? }, ???? ????change:?function(event,ui){ ???? var?intTmp?=?$(this).spinner("value"); ???? if(intTmp?<?0)?$(this).spinner("value",0); ???? if(intTmp?>?10)$(this).spinner("value",10); ???? if(intTmp==8) ???? spnPrev.style.backgroundColor?=?"red"; ???? else ???? spnPrev.style.backgroundColor?=?"blue"; ???? } ????}); ??});
