当我编写代码以上传文件并在按下jqGrid列后获取路径位置时，可以成功选择文件。但是，如果我按下添加按钮，则其行为就像它处于非活动状态一样。我的控制器里什么都没有。
这是我的jgGrid代码。我在script_loc列中执行文件uplaod：
jQuery("#grid").jqGrid({
url:'crud.do',
datatype: 'json',
mtype: 'GET',
colNames:['Seriel Number', 'Script Name', 'Script Location','Host Url','Protocol','Rampup Time','No of Users','Loop','Delay'],
colModel:[
{name:'sr_no',index:'sr_no', width:55,editable:false,editoptions:{readonly:true,size:10},hidden:true},
{name:'script_name',index:'script_name', width:100,editable:true, editrules:{required:false}, editoptions:{size:10, maxlength: 15}},
{name:'script_loc',index:'script_loc', width:100,editable:true, editrules:{required:false},edittype: 'file', editoptions:{enctype: "multipart/form-data"}},
{name:'host_url',index:'host_url', width:100,editable:true, editrules:{required:true}, editoptions:{ size:10, maxlength: 25}},
