jqGrid colmodel.name！= JSON键

i am not good at english(ㅠㅠ)

jqgrid code

colModel : [{
                name:'top_code', align:'center', hidden:true, 
            }, {
                name:'top_code_name', align:'center',
            }, {
                name:'mid_code', align:'center', hidden:true, 
            }, {
                name:'mid_code_name', align:'center',
            }, {
                name:'code', align:'center',
            }, {
                name:'code_name', align:'center',
            }],

private String seq;
private String code; 
private String code_name; 
private String code_gb; 
private String bigo;
private String print_seq;

private String m_cseq;
private String m_code; 
private String m_code_name; 
private String m_code_gb; 
private String m_print_seq;

private String code_depth;

i want

if (depth.value) json.key -> colmodel.name

▼▼▼▼▼▼

  if(code_depth==1){
  code = top_code;
  code_name = top_code_name;
}else if(code_depth==2){
  m_code = mid_code;
  m_code_name = mi_code_name;
}else if(code_depth==3){
 code = code;..
 code_name = code_name;}

Where do I enter the code ? What should I do?

i don't want dynamic binding static colmodel !!
