Jquery automatically fills the checkbox with true

Jquery automatically fills the checkbox with a checkbox (true), and then gets the list of checkboxes through ajax, and then types the options in the list.

 
 A drop-down box <select name="makemodule" id="makemodule" style='width:130px' onchange='makemoduleSelected()'> 
<option value='1'>1</option> 
</select> 

Select changes to trigger the function makemoduleSelected(), which is as follows:

 
//This event is triggered when the template drop-down box changes.
function makemoduleSelected(){ 
clearAll('property'); 
var modtitlecode = $("#makemodule").val(); 
$.ajax({ 
url : 'indexStatisticsAction_getSelect.jsp', 
data: { page:'clientindexStatistics.jsp',method:'get_subname_en',modtitlecode:modtitlecode}, 
success : function(result){ 
//The result returns information to determine whether the login was successful
var results = result.split(","); 
//document.getElementById(results[i]).checked = true; 
$(".indexStatistics").each(function(){ 
$(this).find("input").each(function(){ 
var tempVal = $(this).val(); 
for(var i=0; i<results.length; i++){ 
if(tempVal == results[i]) $(this).attr("checked", true); 
} 
}); 
}); 
} 
}); 
} 

This function makes an ajax-style request to indexstatisticsaction_getselection.jsp, returns a string, splits the modified string into an array of strings, and then iterates through the label < Div class = "indexStatistics >" The tag below is checked (true) when the relevant tag is encountered. The relevant code for indexstatisticsaction_getselection.jsp is as follows:

 
//Gets the index for the template
if(method.equals("get_subname_en")){ 
String modtitlecode = request.getParameter("modtitlecode"); 
if(modtitlecode.equals("-------")) return; 
String sql = sql2.replace("?modtitlecode?",modtitlecode); 
sql = sql.replace("?userId?",userId); 
System.out.println(sql); 
StringBuffer subnames = new StringBuffer(); 
Db db = new Db(); 
try { 
db.prepareQuery(); 
ResultSet rs = db.executeQuery(sql); 
while (rs!=null && rs.next()) { 
subnames.append(rs.getString("subname_en")); 
subnames.append(","); 
} 
rs.close(); 
} catch (Exception e) { 
e.printStackTrace(); 
} finally { 
db.endQuery(); 
} 
PrintWriter pout = response.getWriter(); 
pout.write(subnames.toString().substring(0,subnames.length()-1)); 
pout.flush(); 
pout.close(); 
}
