jqgrid获取所有网格列名称

Question

有没有办法获得所有网格的列名？

Answer 1

You can get the column names with

var columnNames = $("#list")[0].p.colNames;

or

var columnNames = $("#list").jqGrid('getGridParam','colNames');

The only small problem is that the array columnNames will contain up to three empty first elements in case of you use rownumbers:true , multiselect:true or subGrid:true parameters. This parameters to follow to inserting in the colModel additional columns with the names 'rn' , 'cb' or 'subgrid' . So you can either just ignore the first empty elements of columnNames or look additionally in the colModel ( $("#list")[0].p.colModel or $("#list").jqGrid('getGridParam','colModel') ). The colModel and colNames arrays has the same length and the colModel[i].name can be used to examine whether colNames[i] is the name of "real" column or an additional column added because of the usage one from the tree above mention parameters.
