如何在最新的免费jqgrid中修复filterToolbar中的异常 [英] how to fix exception in filterToolbar in latest free jqgrid

问题描述

使用

$(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会导致filterToolbar出错：

Using latest jqgrid from github this causes error in filterToolbar :

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

推荐答案

如果没有测试用例，很难在代码中进行更改。尽管如此，我还是尝试在8924线附近进行一些更改，以使其更安全。请尝试使用GitHub的最新资源。

It's difficult to make the changes in the code without having an test case. Nevertheless I tried to make some changes near the line 8924 to make it more safer. Please try with the latest sources from the GitHub.
