jQuery实现点击图片简单放大效果

一、html代码如下：

<img class="comment_pics" width="50px" height="50px" src="img/01.jpg"/>

<div class="bg">
    <img class="bgimg" style="max-width: 100%; max-height: 100%; position: fixed;" src="">
</div>

二、css代码如下：

.fillbg { background-color: rgba(0, 0, 0, 0.6); bottom: 0; height: 100%; left: 0; opacity: 0; position: fixed; right: 0; top: 0; width: 100%; z-index: 1100; display:none; }
.fillbg-active { opacity: 1; display:block; }

 

三、jquery代码如下：

<script>
    var newimg;
    var clienth=$(window).height();
    var clientw=$(window).width();
    var w = '250';
    var h = '250';
    $(document).ready(function(){
        $(".comment_pics").bind("click", function(){
            newimg = $(this)[0].src;
            $("body").append('<div class="fillbg"></div>');
            $(".fillbg").addclass("fillbg-active");
            $('.bgimg').css({'width': w+"px",'height': h+"px",'top':(clienth-h)/2+"px",'left':(clientw-w)/2+"px",'z-index':1101});
            $('.bgimg').attr("src",newimg);
        });

        $(".bgimg").bind("click", function(){
            $(".fill-input").removeclass("fill-input-active");
            settimeout(function(){
                $(".fillbg-active").removeclass("fillbg-active");
                $(".fillbg").remove();
            },300);
            $('.bgimg').css({'width': '0px','height': '0px'});
            $('.bgimg').attr("src",'');
        });
    });
</script>
