我有一个包含三列的jQGrid。第一个是下拉（类型：选择）字段，第二个是复选框列表的自定义类型，第三个是文本字段。要求是当用户更改下拉字段（DocGroupname）的值时，DocList字段应为空。因此，当用户更改DocGroupName列的值时，我们需要将DocList列的值设置为空。
我尝试过以下。在更改下拉列值时，调用名为myfunction.Inside的函数，我设置的DocList列的值为null。但它不起作用，那么我做错了什么？请任何人帮我找到解决方案。
JQGrid代码，
function ReqKYCGrid()

$("#divmsgg").show();

data: { "projectSeq":$("#Id").val(),"StartDate":$("#StartDate").val(),"EndDate":$("#EndDate").val() },
success: function (result) {
if (!result) alert('No Document Group Found !!');
},
error: function (error) {
alert('Error' + error);
}
}).responseText;
