jqGrid中的自定义删除功能

Question

I am trying to customize the delete function in jqGrid.

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
);

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 }
    );
});

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

Where am I wrong?

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
    // ...
);

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.

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.
