jquery实现移动端点击图片查看大图特效实现移动端点击图片查看大图特效
本文的需求很简单：点击图片查看大图，再点大图隐藏。多用于移动端，因为移动端屏幕小，可能需要查看大图。
具体实现代码
<!DOCTYPE html>
<html>
<meta charset="utf-8"/>
<head runat="server">
<title>JQuery点击图片查看大图by starof</title>
<style type="text/css">
.exampleImg { height:100px; cursor:pointer;}
</style>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript">
//alert($);
// (function (window, undefined) {
// var MyJQuery = function () {
// window.MyjQuery = window.$ = jQuery; window.$ = MyJQuery;
// };
// })(window);
// alert($);
$.fn.ImgZoomIn = function () {
bgstr = '<div id="ImgZoomInBG" style=" background:#000000; filter:Alpha(Opacity=70); opacity:0.7; position:fixed; left:0;
top:0; z-index:10000; width:100%; height:100%; display:none;"><iframe src="about:blank" frameborder="5px"
scrolling="yes" style="width:100%; height:100%;"></iframe></div>';
//alert($(this).attr('src'));
imgstr = '<img id="ImgZoomInImage" src="' + $(this).attr('src')+'"
onclick=$(\'#ImgZoomInImage\').hide();$(\'#ImgZoomInBG\').hide(); style="cursor:pointer; display:none; position:absolute; z-
index:10001;" />';
if ($('#ImgZoomInBG').length < 1) {
$('body').append(bgstr);
}
if ($('#ImgZoomInImage').length < 1) {
$('body').append(imgstr);
}
else {
$('#ImgZoomInImage').attr('src', $(this).attr('src'));
}
//alert($(window).scrollLeft());
//alert( $(window).scrollTop());
$('#ImgZoomInImage').css('left', $(window).scrollLeft() + ($(window).width() - $('#ImgZoomInImage').width()) / 2);
$('#ImgZoomInImage').css('top', $(window).scrollTop() + ($(window).height() - $('#ImgZoomInImage').height()) / 2);
$('#ImgZoomInBG').show();
$('#ImgZoomInImage').show();
};
$(document).ready(function () {
$("#imgTest").bind("click", function () {
$(this).ImgZoomIn();
});
});
</script>
</head>
<body>
<div>
<!--第一种写法-->
<img class="exampleImg" src="images/03.jpg" id="imgTest"/>
<!--第二种写法-->
<img class="exampleImg" src="images/p1_nav2.png" onClick="$(this).ImgZoomIn();"/>
</div>
</body>
