Stop the events of pagination

[lomonmic]

Hello, sorry if I use an automatic translator, but I don't speak English well.
I would need to stop paging when there is still data to save in datagrid remote.
Is it possible to stop the event and stay on the modified data page?
Thank you.

Thanks for the reply.
I solved the problem this way (see code below)
but I would have preferred to block the event: onSelectPage. It can be done ?

Michele.

var pager = dd.datagrid('getPager');
var popts = pager.pagination('options');
var onSelectPage = popts.onSelectPage;
popts.onSelectPage = function(pageNumber, pageSize){
      
    var rows = $('#tt').datagrid('getChanges');
    alert(rows.length+' rows are changed!');
    if(rows.length > 0)
    {
          var rc = confirm('Ci sono records da salvare. Confermi ?');
          if(rc)
          {
            var dataString = JSON.stringify(rows) ;
            var url = 'save.php';
            $.ajax(url, {
                type:'POST',
                data: {myData: dataString},
                   success: function(data){
                alert($.trim(data) );
                   },
                   error: function(){
                  alert('Errore');
                   }
            });
            }         
          onSelectPage.call(this, pageNumber, pageSize);

      }   
      else
      {
          onSelectPage.call(this, pageNumber, pageSize);
      }

Please try to return false in the 'onBeforeSelectPage' event to stop paging. Be sure to download the newest version from the site.

Code:

pager.pagination({
	onBeforeSelectPage(pageNumber,pageSize){
		if (...){
			return false;
		}
	}
})

Thank you for your suggestion.
I downloaded version 1.9.3, but the onBeforeSelectPage event handler seems not to be handled.
Below the code that I tested that does not display the alert.

....
....
var pager = dd.datagrid('getPager');
var popts = pager.pagination('options');
var onBeforeSelectPage = popts.onBeforeSelectPage;

popts.onBeforeSelectPage = function(pageNumber, pageSize){
      alert('ok');
      return false;
}

Please look at this example https://www.jeasyui.com/demo/test/test9.html. It works fine.

Good morning,
I tried the example and I understand why I can't solve with my code. The example works in Firefox, IExplorer, but in Chrome it doesn't display the alert.

It works fine in Chrome. Please try to refresh your page and make sure the newest 'jquery.easyui.min.js' file is loaded successfully.
