JQuery and JqGrid retrieve data from row
提问by michele
How I can retrieve data from jqgrid row, if I have only the number of the row?
如果我只有行号，如何从 jqgrid 行中检索数据？
For example, what do I have to do if I want the id column of the 3rd row?
比如我想要第3行的id列怎么办？

You can get the data by row id. So you can do following:
您可以通过行 id 获取数据。因此，您可以执行以下操作：
var index = 2; // zero-based index of row so it means the 3rd row
var rowId = jQuery('#list tr:eq('+index+')').attr('id');
(here I suppose that the <table>element of your jqGrid has id="list"). After you know the id of the row you can get the row data with respect of getRowDatamethod or the data from one cell only with respect of getCellmethod:
（在这里我假设<table>您的 jqGrid 元素具有 id="list"）。知道行的 id 后，您可以通过getRowData方法获取行数据，或者仅通过getCell方法获取来自一个单元格的数据：
var dataFromTheRow = jQuery('#list').jqGrid ('getRowData', rowId);
var dataFromCellByColumnIndex = jQuery('#list').jqGrid ('getCell', rowId, 7);
var dataFromCellByColumnName = jQuery('#list').jqGrid ('getCell', rowId, 'Tax');

Please, be carefull with methods getCelland getRowDataif case you are editing the row or cell. "This will return the cell content and not the actuall value of the input element."
如果您正在编辑行或单元格，请小心使用getCell和getRowData方法。“这将返回单元格内容而不是输入元素的实际值。”
