Hi,

In documentation on jQuery.ajax() async parameter there is: "As of jQuery 1.8, the use of async: false is deprecated."

I need to argue with that. This deprecation will make my application unusable.

I'm using ZeroClipboard jQuery plugin called jquery.zclip.js to copy texts to clipboard. But the text to copy is SYNCHRONOUSLY retrieved from server before copy operation. I'm using $.ajax() call in beforeCopy zclip event, and it must be synchronous, otherwise zclip will copy to clipboard previous or none value. There is no other way (at least I don't know any) to do this.

My code (please look at beforeCopy event - that ajax call must finish and execute done() event, before copy event will be fired):

var container;

function putZeroClipboard(){

container = "";

$.ajaxSetup({

async: false,

global: false,

type: "POST",

url: "getso.jsp",

data: { uuid: $("#so-uuid").text() },

timeout: 2000

});

$("#clipboard-copy-button").zclip({

path: "/resources/swf/ZeroClipboard.swf",

copy: function(){

return container;

},

beforeCopy: function(){

$.ajax().done(function(content){

// Populate variable.

if (content.toString().length > 0){

container = content;

} else {

container = "\\n";

}

});

}

});

}

The problem is, that all event in ZeroClipboard and zclip (beforeCopy, copy, afterCopy), are fired from flash action script. So if value to copy to clipboard is prepared in event beforeCopy, it must already be prepared when beforeCopy event ends, and that is only possible when using synchronous AJAX call.

Best regards

Simon
