如何避免在免费的 jqgrid 内联编辑中按下保存按钮的日期损坏

Question

使用来自 How to use input type='date' for date column in jqGrid 的代码的本机 html 日期选择器用于免费 jqgrid 中的日期字段编辑。使用工具栏日期按钮保存行会损坏日期值。

重现步骤：

在Chrome
点击第一行进行编辑
按工具栏中的“保存”按钮

观察到：29.03.2037 日期出现。

预期：日期应保持其值，2007 年 10 月 31 日

如何解决这个问题？

Answer 1

您发布的代码有两个小问题：

您使用了错误的 jQuery UI 日期选择器选项。 dateFormat: "d.m.Y" 应该固定为 dateFormat: "dd.mm.yy".
您应该在所有内联编辑中使用 beforeSaveRow: myBeforeSaveRow 。当前代码仅在通过直接调用 onSelectRow.

editRow

我建议您使用免费 jqGrid 的 inlineEditing 选项：

onSelectRow: function (rowid) {
    var $self = $(this),
        savedRow = $self.jqGrid("getGridParam", "savedRow");
    if (savedRow.length > 0 && savedRow[0].id !== rowid) {
        $self.jqGrid("restoreRow", savedRow[0].id);
    }
    $self.jqGrid("editRow", rowid);
},
inlineEditing: {
    // if defines COMMON inline editing options
    keys: true,
    beforeSaveRow: myBeforeSaveRow
}
