我試圖關閉一個燈箱,當按下轉義鍵但彈出窗口未關閉時。關閉按ESC時的燈箱
$(document).keypress(function(e){
if(e.keyCode==27 && popupStatus==1){
disablePopup();
}
});
下面是完整的代碼:
var popupStatus = 0;
var buttonDivID = "";
var conDivID = "";
//determine which div is clicked
function setDiv(div) {
if(div==1){
conDivID = "#intro";
}
if(div==2) {
conDivID = "#presentation";
}
}
//loading popup with jQuery magic!
function loadPopup(){
//loads popup only if it is disabled
if(popupStatus==0){
$("#backgroundPopup").css({
"opacity": "0.7"
});
$("#backgroundPopup").fadeIn("slow");
$(conDivID).fadeIn("slow");
$(conDivID).CenterIt();
popupStatus = 1;
}
}
//disabling popup with jQuery magic!
function disablePopup(){
//disables popup only if it is enabled
if(popupStatus==1){
$("#backgroundPopup").fadeOut("slow");
$(conDivID).fadeOut("slow");
popupStatus = 0;
buttonDivID = "";
conDivID = "";
}
}
//centering popup
function centerPopup(){
//request data for centering
var windowWidth = document.documentElement.clientWidth;
var windowHeight = document.documentElement.clientHeight;
var popupHeight = $(conDivID).height();
var popupWidth = $(conDivID).width();
//centering
$(conDivID).css({
"position": "absolute",
"top": windowHeight/2-popupHeight/2,
"left": windowWidth/2-popupWidth/2
});
//only need force for IE6
$("#backgroundPopup").css({
"height": windowHeight
});
}
//CONTROLLING EVENTS IN jQuery
$(document).ready(function(){
$("#vid2").click(function(){
//set the lightbox divs
setDiv(2);
loadPopup();
});
//CLOSING POPUP
//Click the x event!
$(".popupContactClose").click(function(){
disablePopup();
});
//Press Escape event!
$(document).keypress(function(e){
if(e.keyCode==27 && popupStatus==1){
disablePopup();
}
});
});
另一種方法,這是點擊X按鈕正確關閉彈出。爲什麼不關閉它?
您是否檢查了您在按鍵處理程序中獲得的鍵碼? jQuery有'event.which',可以用跨瀏覽器來確定哪個鍵被按下:http://api.jquery.com/event.which/ – Pat 2010-08-26 19:23:03
