我使用这个jquery函数来显示一个弹出窗口。在这段代码中,它对于带有CSS标识的段落或div属性可以正常工作。但我想在我的html文件中多次使用它,所以我需要将ID转换为类。 这里是我的js文件:jquery弹出窗口麻烦
//0 means disabled; 1 means enabled;
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/3.25,
"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();
}
});
});
这里是CSS:
#backgroundPopup{
display:none;
position:fixed;
_position:absolute; /* hack for internet explorer 6*/
height:100%;
width:100%;
top:0;
left:0;
background:#000000;
border:1px solid #cecece;
z-index:1;
}
#popupContact{
display:none;
position:fixed;
_position:absolute; /* hack for internet explorer 6*/
width:470px;
background:#FFFFFF;
border:2px solid #cecece;
z-index:2;
padding:12px;
font-size:13px;
}
#popupContact h1{
text-align:left;
color:#6FA5FD;
font-size:22px;
font-weight:700;
border-bottom:1px dotted #D3D3D3;
padding-bottom:2px;
margin-bottom:20px;
}
#popupContactClose{
font-size:14px;
line-height:14px;
right:6px;
top:4px;
position:absolute;
color:#6fa5fd;
font-weight:700;
display:block;
cursor: pointer;
}
#button{
text-align:left;
}
这里是HTML:
<div id="button"><input type="submit" value="submit" /></div>
<div id="popupContact">
<a id="popupContactClose">x</a>
<h1>Description</h1>
<p id="contactArea">
<?php echo $data['description'];?>
</p>
</div>
<div id="backgroundPopup"></div>
它完美的作品,当它被设置为DIV用css id.but现在,如果我将所有'#'更改为'。以使id成为类,它不起作用。如何使它工作?
谢谢:) @Destiny – Shabib 2012-02-16 15:17:05
