jsp网页搜索结果中实现选中一行使其高亮

var assno=""; 
function check(obj,che,rwid){ 
if(obj.checked==true){ 
document.getElementById(rwid).style.background ="blue"; 
assno=document.getElementById(che).value; 
alert(assno); 
} 
} 
 
这是网页中动态生成的html代码： 
 代码如下:

out.println("<tr id="+idrow+"><td align=/"center/"><input type=/"checkbox/" onclick=/"check(this,'"+par+"','"+idrow+"');/"/></td>"); 

out.println("<td id=/""+par+"/"align=/"center/" value=/""+Info.getAssetsNo()+"/">"+Info.getAssetsNo()+"</td>"); 
out.println("<td align=/"center/">"+Info.getSerialNo()+"</td>"); 
out.println("<td align=/"center/">"+Info.getAssetsName()+"</td>"); 
out.println("<td align=/"center/">"+Info.getAssetsClass()+"</td>"); 
out.println("<td align=/"center/">"+Info.getCgTime()+"</td>"); 
out.println("<td align=/"center/">"+Info.getGbTime()+"</td>"); 
out.println("<td align=/"center/">"+Info.getConfigInfo()+"</td>");
