带有“:1”的结构成员声明(Structure member declaration with “ : 1 ”)
我在linux内核文件include / sound / soc-dapm.h中找到了这个结构。 我对其成员的声明感到困惑。我在谷歌上寻找它但找不到任何信息。 如果有人能够解释为什么在每个变量声明后都有:1,那将是很有帮助的。 这是代码的一部分。
struct snd_soc_dapm_widget { unsigned int off_val; /* off state value */ unsigned char power:1; /* block power status */ unsigned char invert:1; /* invert the power bit */ unsigned char active:1; /* active stream on DAC, ADC's */ unsigned char connected:1; /* connected codec pin */ }
谢谢。
I found this structure in linux kernel file include/sound/soc-dapm.h . I am confused about the declaration of its members.I looked for it on google but couldn't find any informative stuff. If anybody can explain why there is :1 after every variable declaration,it will be great help. Here is a part of the code.
struct snd_soc_dapm_widget { unsigned int off_val; /* off state value */ unsigned char power:1; /* block power status */ unsigned char invert:1; /* invert the power bit */ unsigned char active:1; /* active stream on DAC, ADC's */ unsigned char connected:1; /* connected codec pin */ }
Thanks.

你看过
stateLoadParams
吗?dttblEnrolledUser = $('#tblUsers').dataTable({ ... stateLoadParams: function( settings, data ) { if (data.order) delete data.order; } })
将在每次刷新时有效地重置保存的排序顺序。
Have you looked at
stateLoadParams
?dttblEnrolledUser = $('#tblUsers').dataTable({ ... stateLoadParams: function( settings, data ) { if (data.order) delete data.order; } })
Will effectively reset the saved sorting order on each refresh.

Datatables ServerSide排序不起作用(Datatables ServerSide sort not working. What has gone wrong?)[2021-10-17]

使用Datatables jquery插件对关于组的行进行排序(Ordering rows respecting groups using Datatables jquery plugin)[2022-03-17]
最后我解决了。 起初我看了一下DataTables的分组附加组件 ,但它在排序和过滤方面效果不佳所以我决定以另一种方式做到这一点。 每一行都有数据。 如果它是一个组,那么它将被复制但是它将被隐藏为具体的CSS样式。 像这样,用户会看到“组”,过滤和排序将一如既往地工作。 在搜索过滤的情况下,使用jQuery,我再次显示每个组的第一行(如果搜索返回隐藏的半行) Finally I solved it. At first i took at look at the Grouping Add-on of Data ... -
