jquery弹出窗口

Question

我试图在当前默认页面上加载悬停页面。到目前为止，悬停弹出窗口的时尚，但然后马上淡出。我不确定下面我做错了什么。任何帮助，将不胜感激。

JS文件

var popupStatus = 0; 

//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"); 
    $("#popupContact").fadeIn("slow"); 
    popupStatus = 1; 
} 
} 

//disabling popup with jQuery magic! 
function disablePopup(){ 
//disables popup only if it is enabled 
if(popupStatus==1){ 
    $("#backgroundPopup").fadeOut("slow"); 
    $("#popupContact").fadeOut("slow"); 
    popupStatus = 0; 
} 
} 

//centering popup 
function centerPopup(){ 
//request data for centering 
var windowWidth = document.documentElement.clientWidth; 
var windowHeight = document.documentElement.clientHeight; 
var popupHeight = $("#popupContact").height(); 
var popupWidth = $("#popupContact").width(); 
//centering 
$("#popupContact").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(){ 

//LOADING POPUP 
//Click the button event! 
$("#button").click(function(){ 
    //centering with css 
    centerPopup(); 
    //load popup 
    loadPopup(); 
}); 

//CLOSING POPUP 
//Click the x event! 
$("#popupContactClose").click(function(){ 
    disablePopup(); 
}); 
//Click out event! 
$("#backgroundPopup").click(function(){ 
    disablePopup(); 
}); 
//Press Escape event! 
$(document).keypress(function(e){ 
    if(e.keyCode==27 && popupStatus==1){ 
     disablePopup(); 
    } 
}); 

});

良好的第一步是确保您的单击事件被妥善处理，以避免不必要的冒泡。您可以与每点击处理函数做到这一点：

$("#button").click(function(e){ 
    e.preventDefault(); 
    //centering with css 
    centerPopup(); 
    //load popup 
    loadPopup(); 
}); 

这可能导致该问题停止发生，即使它不是，它是为了防止在未来发生怪异的行为是个好主意。您可以在这里阅读有关preventDefault的更多信息：http://api.jquery.com/event.preventDefault/
