Hi all,

After days of madness I finally ask for help,

Before validate form i need to send a file with postdata to an ftp , wait response and if it's ok validate form in jqgrid , else display form error message.

for that i try to use beforesubmit

send_ftp.php return json data if Ok, html text if it fail.

beforeSubmit : function(postdata, formid) {

var Res = false;
$.post( 'send_ftp.php', { InfoCl: postdata })
.done(function( data ) {
try {
jQuery.parseJSON(data);
} catch(error) {
Res = false;
}
var obj = jQuery.parseJSON( data );
if(obj.type == null || obj.mut == null) {
Res = false;
}else{
Res = true;
}
}
return[Res];
}

but $.post is asynchronous call so script continue to run and Res is always False.

i do not want to use async false cause it lock browser and can't dislay blockUI before request to prevent user

what i'v try too is

beforeSubmit : function(postdata, formid) {
$(document).ajaxStop($.unblockUI);
$.blockUI({ message: '<h1 class=\"spinner\"><img src=\"../images/busy_small.gif\" /> Send http://FTP...</h1&gt;' });
$.post( 'send_ftp.php', { InfoCl: postdata })
.done(function( data ) {
var Res;
try {
jQuery.parseJSON(data);
} catch(error) {
TriggerError('list1', 'Error FTP');
}
var obj = jQuery.parseJSON( data );
if(obj.type == null || obj.mut == null) {
TriggerError('list1', 'Error FTP');
}else{
// Here i must validate form manually!
}

}
return(false);
}

function TriggerError(tbgrid, texte)
{
$("#FormError>td","#TblGrid_"+tbgrid).text(texte);
$("#FormError>td>ul","#TblGrid_"+tbgrid).css({'list-style-type': 'disc', 'list-style-position': 'outside'});
$("#FormError","#TblGrid_"+tbgrid).show();
}

this wotk but after that i must manually validate the form , do not know if it's possible

any idea how can achieve that in any ways ?

regards to all and sorry for my bad english

Hello,

 

I recommend you to use async:false in your post ajax function. During this process you can set a wait message.
