1.html 代码
<div id="imgEnlargeDiv" style="display: none; text-align: center;position: fixed;z-index: 1000;top: 0;left: 0;
width: 100%;height: 100%;background-color: rgba(255,255,255,.9);">
<img id="bigimg" style="height: auto;width: 40%;border: 0;
margin: auto;position: absolute;top: 0;bottom: 0;left: 0;right: 0;" src="" />
</div>
2.js 代码
<script src="assets/js/jquery-1.10.2.min.js"></script> <!--引入jquery -->
<script type="text/javascript">
//图片放大
$(function(){
$("#imgEnlargeDiv").click(function(){//再次点击淡出消失弹出层
$(this).fadeOut("fast");
});
});
function imgShow(outerdiv, bigimg, _this){
var src = _this.attr("src");//获取当前点击的pimg元素中的src属性
$(bigimg).attr("src", src);//设置#bigimg元素的src属性
$(outerdiv).fadeIn("fast"); //图片放大的div快速淡入显示层
}
function imgEnlarge() {
$("img[type ='showImg']").mouseover(function(){
$(this).css("cursor","pointer");//鼠标移动到图片,鼠标箭头变为手势
});
$("img[type ='showImg']").click(function(){
var _this = $(this);//将当前的pimg元素作为_this传入函数
imgShow("#imgEnlargeDiv", "#bigimg", _this);
});
}
</script>
3.使用
调用imgEnlarge(); 则会对$("img[type ='showImg']")的图片添加点击事件。
点击图片后则会弹出图片放大层。
