这是我的代码。我正在使用 jquery version4.4.0 但是该列仍然没有被冻结。请帮助我解决这个问题。我也尝试过调试代码。方法“setFrozencolumns”被调用，但列没有被冻结

【问题讨论】：

标签： jquery jqgrid

【解决方案1】：

要使用setFrozenColumns，您需要通过在colModel 中设置frozen:true 来标记应冻结哪些列。请在此处阅读更多内容：

Frozen Columns - Setup and limitations

更新

setFrozenColumns 方法从 jqGrid 4.3.0 版开始可用。您还应该确保您已经检查了 download page 上 Base 部分中的 Custom 模块（如果您使用的是未压缩分发，则参考 grid.custom.js 文件）。

【讨论】：

我也试过了.. 但它给了我一个“找不到方法错误”
我也粘贴了编辑后的代码。请检查并帮助我
@Xavier 我已经更新了答案，其中包含有关该方法可用位置的一些详细信息。
我已经下载了 v 4.4.0 并在我的代码中添加了以下脚本文件。错误已解决，但列尚未冻结..请帮帮我
@Xavier 您可以在调用 setFrozenColumns 后尝试调用$("#sample").trigger('reloadGrid', [{current:true}]);，但如果您没有打破我给您的链接中描述的任何限制（并且您已验证您是使用正确版本的 jqGrid）比一切都应该正常工作（至少没有什么可以从你描述的内容中诊断出来）。

【解决方案2】：

试过了，现在可以正常使用了..

$("#sample").jqGrid("destroyFrozenColumns")
            .jqGrid("setColProp", "id", { frozen: true })
            .jqGrid("setFrozenColumns")
            .trigger("reloadGrid", [{ current: true}]);
