jqGrid中的自定义删除功能 [英] Custom Delete Function in jqGrid

问题描述

我正在尝试自定义 jqGrid 中的删除功能.

I am trying to customize the delete function in jqGrid.

我已启用网格上的删除按钮

I have enabled the delete button on the grid

$("#myGrid").jqGrid('navGrid', '#pager',
    { add: true, addtitle: 'Add Customer',
        edit: true, edittitle: 'Edit Customer',
        del: true, deltitle: 'Delete Customer',
        refresh: true, refreshtitle: 'Refresh data',
        search: true, searchtitle: 'Apply filters', 
        addfunc: addForo, editfunc: editForo, 
        cloneToTop: true
    },
    {}, // default settings for edit
    {}, // default settings for add
    {}, // default settings for delete
    { closeOnEscape: true, multipleSearch: true, closeAfterSearch: true }, // search options
    {} // default settings for view
);

然后我添加了(感谢此post)以下代码

then I have added (thanks to this post) the following code

$("#bDelete").click(function () {
    // Get the currently selected row
    toDelete = $("#myGrid").jqGrid('getGridParam', 'selrow');
    $("#myGrid").jqGrid(
        'delGridRow',
        toDelete,
        { url: '/Foro/Delete/' + toDelete, mtype: 'post', reloadAfterSubmit: false }
    );
});

现在，当我单击删除按钮时，会显示一个对话框，要求确认删除.但是如果我点击删除按钮，我会收到以下错误消息

Now when I click on the delete button a dialog is shown asking for delete confirm. But if I click on the delete button I will get the following error message

我哪里错了?

推荐答案

如果我理解你是正确的，你想修改用于删除行的 url 以便行的 id 将是url 的一部分.你可以更轻松地做到这一点:

If I understand you correct you want to modify the url used to delete of row so that the id of the row will be a part of the url. You can do this much easier:

$("#myGrid").jqGrid('navGrid', '#pager',
    // define navGrid options and paraneters of Edit and Add dialogs
    { // now define settings for Delete dialog
      mtype: "POST", reloadAfterSubmit: false,
      onclickSubmit: function(rp_ge, postdata) {
          rp_ge.url = '/Foro/Delete/'+ postdata;
      },
      serializeDelData: function (postdata) { return ""; }
    },
    // search options
    // ...
);

关于onclickSubmit我们可以修改url和定义serializeDelData我们可以清除POST"消息的正文.我个人主要在服务器端使用 RESTfull 服务并使用 mtype: "DELETE".在这种情况下确实需要清除尸体.

With respect of onclickSubmit we can modify the url and defining of serializeDelData we can clear the body of the "POST" message. I peronally mostly use RESTfull services on the server side and use mtype: "DELETE". In the case to clear of the body is really needed.

另一种选择是使用 delfunc，就像您已经使用 editfunc 和 addfunc 一样.在大多数情况下，这种功能的使用并不是真正需要的，可以通过其他方式实现.

One more option is to use delfunc like you already use editfunc and addfunc. In the most cases the usage of such function is not really needed and one can implement the same in other way.
