如何在最新的免费 jqgrid 中修复 filterToolbar 中的异常

how to fix exception in filterToolbar in latest free jqgrid

Jqgrid 过滤器工具栏是使用

创建的
$(function () {
    $grid.jqGrid('filterToolbar', { // this is line myapp.js:797 in stack trace below
        stringResult: true,
        searchOnEnter: true,
        defaultSearch: 'cn'
    });
});

使用来自 github 的最新 jqgrid 这会导致 filterToolbar 出错:

Uncaught TypeError: Cannot read property 'toUpperCase' of undefined
url http://localhost:52216/admin/Scripts/jqgrid/js/jquery.jqgrid.src.js
lineNumber  8924    column  24

如何解决这个问题? 堆栈跟踪如下。

TypeError: Cannot read property 'toUpperCase' of undefined
    at parseFilter (http://localhost:52216/admin/Scripts/jqgrid/js/jquery.jqgrid.src.js:8924:24)

如果没有测试用例,很难在代码中进行更改。尽管如此,我试图在 8924 行附近设置 some changes 以使其更安全。请尝试使用来自 GitHub 的最新资源。
