回答：你参考下：$(".x-table td").mouseover(function(e){var col=Number($(this).attr("col"));var row=$(this).attr("row"); //获取鼠标当前所在单元格的row var img=contentPane.curLGP.getCellValue("14",row); //获取到隐藏的图片地址//alert (col+row+img);if(col==14)$("body").append("<div id='preview'><img src='"+ img +"'/ width=400></div>"); //弹出一个div里面放着图片$("#preview")//修改这个div的样式，让他居中//.css("width",10)//.css("height",5).css("-ms-transform","translate(-50%,-50%)").css("-moz-transform","translate(-50%,-50%)").css("-o-transform","translate(-50%,-50%)").css("transform","translate(-50%,-50%)").css("left","15%").css("top","80%").css("z-index","99999").css("position","absolute")});//鼠标离开这个div移除$(".x-table td").mouseout(function(e){ $("#preview").remove();});
