jquery - jqgrid 发送空 ("") 值与 stype:'select' 和 searchoptions:{dataUrl:...} 如果用户提交搜索表单而不更改所选值

Question

我正在将 jqgrid 与这样的列一起使用：

{label:'test',
name:'dn',
index:'dn_id',
sortable:false,
align:'center',
editable:false,
search:true,stype:'select',
searchoptions:{
    sopt: ['eq'],
    defaultValue:'1000',
    dataUrl:'<?php echo URL::base().'reports_dn/get_dns';?>'}
}

从 dataUrl 成功创建了选择下拉列表。但是如果用户选择搜索并按下提交按钮而不更改当前下拉选择，则会将空值发送到“dn_id”的服务器。但如果我更改下拉选择的值，它可以正常工作。这似乎是一个错误，但我不确定。请帮忙。谢谢
