javascript - 如何修复最新免费jqgrid中filterToolbar中的异常

Question

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 github 上的最新 jqgrid 这会导致 filterToolbar 出现错误:

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。

如果没有测试用例，很难对代码进行更改。尽管如此，我还是尝试制作 some changes 8924线附近，更安全。请尝试使用 GitHub 上的最新源。
