javascript - 有隐藏行时jqGrid冻结列

Question

我有一个带有一些隐藏行的网格。我需要冻结前两列，但我发现如果有一些隐藏的行，'setFrozenColumns' 不起作用。有同样问题的人吗？你能帮助我吗？谢谢。

Answer 1

你的意思是隐藏行还是隐藏列？目前 - 从 4.3.2 开始 - 冻结列具有以下限制：

以下限制告诉您何时无法设置冻结列

• 启用 TreeGrid 时
• 启用子网格时
• 启用 cellEdit 时
• 使用内联编辑时 - 无法编辑冻结的列。
• 启用可排序列时 - 网格参数 sortable 设置为 true 或者是函数
• 当滚动设置为 true 或 1
• 启用数据分组时

因此，如果您使用的是 TreeGrid 或 SubGrid，冻结列将根本不起作用。

如果您的意思是您有隐藏的列，那么冻结的列应该可以工作 - 您可能需要发布代码或演示问题的小示例。

这是一个完整的例子：

jQuery("#list47").jqGrid({

});



document.getElementById("1").style.display = 'none';
$("#list47").jqGrid("destroyFrozenColumns") 
                .jqGrid("setColProp","id",{frozen:true})
                .jqGrid("setColProp","invdate",{frozen:true})                 
                .jqGrid("setFrozenColumns")

在这种情况下，只是标题被冻结，而不是整个列。
