在JQGrid中冻结列

Question

有没有办法让jqGrid冻结一个或多个最左边的列,并使列的余额左右滚动？

我在谷歌至少有一个声称在这里做过的人:http://www.trirand.com/blog/？page_id = 393 /discussion / new-free-column-plugin /

...但示例代码消失了.(具有讽刺意味的是,它工作的截屏仍在播放,嘲笑我.)

看起来这里的一些人也使它工作,但不包括代码.

有没有人使用滚动工具在jqGrid中使用该插件或其他类似的插件获得冻结列？任何人都有这个代码工作和方便吗？

我原本以为你会包含那个人的代码,它会自动生成你可以在他的截屏视频中看到的图钉,如果没有,你会让魔法发生......

$(document).ready(function() {
    //$("#tblImz").jqGrid().freezingSetup(); // initially tried without this line; same error (reporting different function, natch)
    $("#tblImz").jqGrid().freezeColumn(2);
});

......但那给了我......

Microsoft JScript运行时错误:对象不支持属性或方法'freezeColumn'

要么

Microsoft JScript运行时错误:对象不支持属性或方法'freezingSetup'

只是为了好玩,这里是我认为几乎正确的清理代码,取自上面帖子的粘贴.我认为这准确地转发什么提交人[无意中错位了在他的trirand.com论坛上发帖,从两个编辑在这里通过linoj建议.好的,代码转储......

有任何想法吗？

冻结列现在在jqGrid 4.3中实现.查看官方演示,在左侧树的底部选择" Frozen Cols.Group Header(new) ",然后选择演示" Frozen column "或" Frozen column with group header ".
