jQuery jqGrid在编辑行完成时显示消息 [英] jQuery jqGrid Show message when an edit row is complete

问题描述

我在这里按照本教程。

在实际示例中，您将导致代码写入状态消息 afterSubmit 事件处理程序和代码它返回 errorTextFormat 内的错误消息。

I am following this tutorial here http://www.trirand.com/blog/jqgrid/jqgrid.html in LiveDataManipulation->EditRow

My grid receive data from script a.php. After the user can modify this data by the jqGrid. jqGrid after the modification data will send data to script B.php that update my database and return a message of response like "all goes well".
I want that this response is alerted or showed to user somewhere on the page.
Reading the tutorial and here http://www.trirand.com/jqgridwiki/doku.php?id=wiki:form_editing I think that I've to use afterSubmit option, but I haven't understood how print on the edit panel the result.

I have written:

$("#editImpresa").click(function(){
var gr = jQuery("#tabImprese").jqGrid('getGridParam','selrow');
if( gr != null ) jQuery("#tabImprese").jqGrid('editGridRow',gr,{
    height:690,
    width:500,
    closeAfterEdit : true,
    reloadAfterSubmit:false,
    afterSubmit: function(response,postdata){ 
       if(response.responseText=="ok")
            success=true;
        else success = false;

        return [success,response.responseText] 
    }
});

How can I do it? Thanks.

解决方案

First of all the option closeAfterEdit:true follows to closing of the edit form after the successful server response. You should change the setting to the default value closeAfterEdit:false to be able to show anything.

Next I would recommend you to use navigator toolbar instead of creating a button after outside of the grid. In the case you can use

var grid = jQuery("#tabImprese");
grid.jqGrid('navGrid','#pager', {add:false,del:false,search:false}, prmEdit);

One more good option is to use ondblClickRow event handler

ondblClickRow: function(rowid) {
    $(this).jqGrid('editGridRow',rowid,prmEdit);
}

(see here) or both ways at the same time.

In any way you have to define the options of editGridRow method (the prmEdit). It's important to know that afterSubmit will be called only if the server response not contains error HTTP status code. So you should use errorTextFormat to decode the error server response. The afterSubmit event handler you can use to display status message.

In the demo I used only errorTextFormat to demonstrate both displaying of the status and error message:

The status message goes away in 3 seconds:

The corresponding demo you will find here.

In real example you will of cause place the code writing status message inside of afterSubmit event handler and the code which returns the error message inside of errorTextFormat.
