JSP page search results in the implementation of a selected line of its highlighting

When I did the search results, I used an onclick event to highlight the selected lines for good looks:

 
var assno=""; 
function check(obj,che,rwid){ 
if(obj.checked==true){ 
document.getElementById(rwid).style.background ="blue"; 
assno=document.getElementById(che).value; 
alert(assno); 
} 
} 

This is the dynamically generated HTML code in the web page:

 
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>");
