 * The first 5 lines are boiler plate found on all(i think) DCmd jqgrids
 * The create criteria creates a corresponding sql table of the comic book attributes
 *      The if statements inside the create criteria allow for searching in at the top of each column
 * The ' '  in the collection corresponds to the editing action for a row on the grid -- the little pin widget

我不确定我的控制器或视图中是否存在问题，以确定无法看到我添加到网格中的数据的原因。

Answer 1

找出数据未显示的原因。这是我的url和editUrl行。我认为那是我想要数据的网址，而是将其替换为listAllMobileSuits for url和editAllMobileSuits for editURl，它们是列表的函数名称，并编辑我控制器中的网格。

转过来

url: 'MobileSuits/mobileSuits',
editurl: 'MobileSuits/editAllMobileSuits',

到

url: 'listAllMobileSuits',
editurl: 'editAllMobileSuits',

jqgrid没有显示数据行
