Title: edatagrid - bug with onBeforeSave and autoSave [fixed]
Post by: Stefan B. on February 11, 2015, 03:57:46 AM

We use a table with autoSafe:true and valide something in the event methode onBeforeSave

Code:

ddv.edatagrid({
	pagination: true,
	singleSelect:true,
	autoSave: true,
	columns:[[
		{fields ...}
	]],
	onBeforeSave: function(index) {
		//check special flags
		if(!handleCheckMigrationSuccessfulAndFallbackFlags($(this), index)) {
			return false;
		}
		return true;
	}
	...
});

The autosave works fine if the result of onBeforeSave is true.

But after the first time onBeforeSave returns false
and changing the row fields so that onBeforeSave return true
the autosave is not working any more.

What can be here the problem?

What does you function 'handleCheckMigrationSuccessfulAndFallbackFlags' do? Please provide an example to demonstrate your issue.

The method checks something and only return true or false.

We tests something. And the event onBeforeSave is only trigger one time
when autoSave is true and click outside the datagrid!

Please refer to this example https://jsfiddle.net/y0obkqaa/. If your issue continues, try to download the updated edatagrid plugin from http://www.jeasyui.com/extension/edatagrid.php

Hi. I try your exsample. Your exsample code is not working why you use a wrong JQuery version.
I copy the code to my new exsample:
http://jsfiddle.net/sbrandt/0hk1twng/

Whi the new jquery.edatagrid.js it is now working!

But now we have a bigger problem when one alert message should shown in the else block!
Then we have a loop on the event and the application hangs!

Code:

        onBeforeSave: function(index){
            var ed = $(this).edatagrid('getEditor',{index:index,field:'f4'});
            if ((ed.target).is(':checked')){
                //use the alert and the onBeforeSave event is called in a loop when autoSave is active!!!
                //$.messager.alert('error', 'message cannot save why ....' , "warning");
                return false;
            }
        }

How can we now sho an alert message here?
