两种jqery方法实现滑动到图片预览功能

小渣渣 · 发表于 2015-8-19 21:21:57

效果图如上：

当鼠标划过图片的时候，会获取焦点，生成一个大图片的样式，并随着鼠标移动

当鼠标离开后，会自动销毁大图片，两种方法，推荐第二种，最后附上demo。

方法一：

img {

width: 200px;
border:solid 1px #666666;

#divBigImg {
height: 400px;
width: 500px;
border:solid 1px #666666;
position:absolute;
}
#BigImgId {
height: 400px;
width: 500px;
border:solid 1px #666666;
}
li {
float: left;
margin-left:5px;
}
-->
</style>
<scrip去掉t>
$(function(){
$("ul li a").bind("mouseover",function(e){
var x=e.pageX+10;
var y=e.pageY+10;
var herf=$(this).attr("href");
//$("#divBigImg").css("display","block");
$("#divBigImg").css({"display":"block","left":x,"top":y})
$("#divBigImg").attr("src",herf);
}).mousemove(function(e){
var x=e.pageX+10;
var y=e.pageY+10;
var herf=$(this).attr("href");
//$("#divBigImg").css("display","block");
$("#divBigImg").css({"display":"block","left":x,"top":y})
$("#divBigImg").attr("src",herf);
}).mouseout(function(){
$("#divBigImg").css("display","none")
});
});
</scrip去掉t>
<body>
<ul>
<li><a href="Images/1.jpg" class="toolTip" title="LinkTitle1"><img src="Images/1.jpg" alt="ImgAlt1" /></a></li>
<li><a href="Images/2.jpg" class="toolTip" title="LinkTitle1"><img src="Images/2.jpg" alt="ImgAlt1" /></a></li>
<li><a href="Images/3.jpg" class="toolTip" title="LinkTitle1"><img src="Images/3.jpg" alt="ImgAlt1" /></a></li>
<li><a href="Images/4.jpg" class="toolTip" title="LinkTitle1"><img src="Images/4.jpg" alt="ImgAlt1" /></a></li>
</ul>
<img src="Images/1.jpg" alt="ImgAlt1" id="divBigImg" style="display:none;" />
</body>
</html>
