直接上代碼：
var str = "";
document.writeln("<div id=\"_contents\" tabindex=9999 onblur=\"hideSetTime()\" style=\"padding:6px; background-color:#E3E3E3; font-size: 12px; border: 1px solid #777777; position:absolute; left:?px; top:?px; width:?px; height:?px; z-index:1; visibility:hidden\">");
str += "\u65f6<select id=\"_hour\" style='width:65px' onchange='changeHour()'>";
for (h = 0; h <= 9; h++) {
str += "<option value=\"0" + h + "\">0" + h + "</option>";
}
for (h = 10; h <= 24; h++) {
str += "<option value=\"" + h + "\">" + h + "</option>";
}
str += "</select> \u5206<select id=\"_minute\" style='width:65px'>";
for (m = 0; m <= 9; m++) {
str += "<option value=\"0" + m + "\">0" + m + "</option>";
}
for (m = 10; m <= 59; m++) {
str += "<option value=\"" + m + "\">" + m + "</option>";
}
str += "</select> \u79d2<select id=\"_second\" style='width:65px;display:none;'>";
for (s = 0; s <= 9; s++) {
str += "<option value=\"0" + s + "\">0" + s + "</option>";
}
for (s = 10; s <= 59; s++) {
str += "<option value=\"" + s + "\">" + s + "</option>";
}
str += "</select> <input name=\"queding\" type=\"button\" onclick=\"_select()\" value=\"\u786e\u5b9a\" style=\"font-size:12px\" /></div>";
document.writeln(str);
var _fieldname;
function _SetTime(tt) {

var ttop = tt.offsetTop; //TT控件的定位點高
var thei = tt.clientHeight; //TT控件本身的高

while (tt = tt.offsetParent) {

}
document.getElementById("_contents").style.top = ttop + thei + 4+"px";

問題：如果是失去焦點的時候隱藏？
解決：一般onblur事件是給form表單的input、按鈕等使用，如果要給div、span、a.....等等這類標簽使用的話，要加tabindex.
tabindex=9999 onblur=\"hideSetTime()\"
這樣便可以在div中加onblur事件。
你是不是也遇到這種問題呢？(*^__^*) 嘻嘻……
