jqGrid 中的 `getNodeParent` 函数是用来获取指定行的父节点的函数。该函数需要两个参数:第一个参数是行 ID,第二个参数是行数据。
例如,如果你想要获取某行的父节点,可以使用以下代码:
```javascript
var rowId = "123"; // 行 ID
var rowData = jQuery("#grid").jqGrid('getRowData', rowId); // 行数据
var parentRowData = jQuery("#grid").jqGrid('getNodeParent', rowId, rowData); // 父节点数据
```
该函数返回一个对象,包含父节点的 ID 和数据。如果当前行没有父节点,返回 `null`。

jqGrid jsonreader
jqGrid是一个流行的jQuery表格插件,它可以用于展示和编辑数据。而jsonreader是它的一个重要配置项,用于指定从服务器返回的JSON数据如何解析成表格中的行和列。
jsonreader有几个可配置的属性,包括:
- root: 指定包含行数据的JSON对象的属性名,默认为"rows"。
- page: 指定当前页码的属性名,默认为"page"。
- total: 指定总页数的属性名,默认为"total"。
- records: 指定总行数的属性名,默认为"records"。
- repeatitems: 指定是否使用相同的属性名重复表示每一列的值,默认为true。
通过配置jsonreader,可以将服务器返回的JSON数据按照指定的格式解析成表格中的行和列,进而实现数据的展示和编辑等功能。
jqgrid loadComplete
"jqgrid loadComplete" is an event that is triggered after the data has been loaded into a jqGrid, and the grid has been populated with rows. This event can be used to perform additional processing or manipulation of the data, or to customize the appearance or behavior of the grid.
Here is an example of how you might use the "jqgrid loadComplete" event to customize the appearance of a jqGrid:
```javascript
$("#myGrid").jqGrid({
url: "data.php",
datatype: "json",
colModel: [
{ name: "id", label: "ID", width: 50 },
{ name: "name", label: "Name", width: 200 },
{ name: "age", label: "Age", width: 50 },
// other columns...
],
loadComplete: function(data) {
// Set the background color of even-numbered rows to light gray
$("#myGrid tr:even").css("background-color", "#f9f9f9");
}
});
```
In this example, the "loadComplete" event is used to set the background color of even-numbered rows to light gray. The event handler function is passed a "data" parameter that contains the loaded data, which can be used to perform additional processing or manipulation of the data if needed.
The "loadComplete" event can be useful for customizing the appearance or behavior of a jqGrid based on the loaded data, or for performing additional processing or manipulation of the data before it is displayed in the grid.
