<script type="text/javascript">
 $(function() {
 $("td").on("mouseenter", function() {
 //js主要利用offsetWidth和scrollWidth判断是否溢出。
 //在这里scrollWidth是包含内容的完全高度，offsetWidth是当前表格单元格的宽度。
 if (this.offsetWidth < this.scrollWidth) {
 var that = this;
 var text = $(this).text();
 window.layer.tips(text, that, {
 tips: 1,
 time: 2000
 });
 }
 });
 })
</script>
</body>
</html>
