1，设置css样式
<style>
table {
width: 100%;
float: left;
table-layout:fixed;
width:600px;
border:1px solid #ccc;
}
table tr {
line-height: 25px;
border:1px solid #ccc;
}
table td {
border:1px solid #ccc;
text-align:center;
}
.mhover{
border:1px solid #ccc;
white-space:nowrap;
text-overflow:ellipsis;
overflow:hidden;
}
</style>
2，js设置click和mousemove和mouseout事件
<script>
$(document).ready(function () {
$(“.mall”).hide();
$(“.mhover”).click(function (e) {
$(this).next(“.mall”).css({“position”:”absolute”,”top”:e.pagey+5,”left”:e.pagex+5}).show();
});
$(“.mhover”).mousemove(function (e) {
$(this).next(“.mall”).css({ “color”: “fff”, “position”: “absolute”, “opacity”: “0.7”, “background-color”: “666”, “top”: e.pagey + 5, “left”: e.pagex + 5 });
});
$(“.mhover”).mouseout(function () {
$(this).next(“.mall”).hide();
});
});
</script>
3，html内容,在td中新增两个div，两个div中的内容必须一致。
<table>
<tr>
<th>姓名</th>
<th>个性签名</th>
<th>性别</th>
</tr>
<tr>
<td>狗子</td>
<td>
<div class=”mhover”>嘻嘻嘻嘻嘻哈哈12345上山打老虎嘻嘻嘻嘻嘻哈哈</div>
<div class=”mall”>嘻嘻嘻嘻嘻哈哈12345上山打老虎嘻嘻嘻嘻嘻哈哈</div>
