I am not very hopeful that a platform issue might happen here. I don't have access to WIN box at the moment so can't verify. However the question remains is this a settimeout issue or a csinterface issue. Did you try what i suggested? Just make plain simple two calls sequentially for getText and then check method. Are you even able to get both the methods called even in this case? If not then it is an InDesign problem, else it means it has something to do with your settimeout or callback chaining, and that is more of a JS question.

 

Anyhow in the current state i don't get what workflow you are trying to make, why is check not in the callback of getText, is it dependent on its result or not, why did you use settimeout in the first place, why is it needed

    ok thanks for replying...i used json method for retuning but wanted to ask if instead of res if i use another function in callback like check in callback of gettext then check will take the ouput of gettext function?

    Ok so you mean to say check method is called but the return value is not what you expect and its blank or undefined, right? If so then we will need to have a look at your jsx code for check method, that should be the culpritm csinterface is working fine on sending your call to jsx engine. Paste the snippet for check method, i will have a look

    actually initially code was

    function check()
    {
        var mydoc = app.documents.item(0);
            var item = app.selection;
            var myframe = item[0];
            var paras = myframe.parentStory.contents;
            return paras;
    }
    which wasnt working so replaced it by return 1 simply to check if it is returning anything.
    thank you for your help .should i add my whole code in dropbox or just paste the particular function

    Upload the whole extension folder to dropbox and give the public access url here.

    This does not give you anything to help you. Tell us what do you call? How do you call? Do you mean you are just able to call only a particular method using csinterface, or that you are only able to make just one method call in a session?

    Paste code snippets, explain it better so that we can understand the problem.

      in this snippet i am not able to get returned value from check fn. but i have got returned value from gettext .why is it so when i have used the same process.check() function returns 1 or 0  from jsx code.actually the other fns used do not retiurn any value so they work well but as i have a secong fn i.e check which returns a value it does not work
       

       

       

       

      function translate()
{
	csInterface.evalScript("getText()", function(res)
	{
		var t='?translator_id='+document.getElementById("f").value;
		//alert(t);
		var v='&target='+document.getElementById("g").value;
		//alert(v);
		var url='http://localhost:3000/translate'+t+v;
		//var url = 'http://localhost:5000/name?pd=1&target=fr' ;
		var para = res.split("\r");
		for(var i=para.length;i>=0;i--)
		{
			if(para[i]==undefined)
				continue;
			//csInterface.evalScript("alert('" + para[i] + "')");
			var da = JSON.stringify({ "data" : para[i] });
			var xhr = new XMLHttpRequest();
			xhr.open('POST', url, false);
			xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
			xhr.onload = function (e)
			{
				if (this.status == 200 || this.status == 304)
				{
					var lan = document.getElementById("g").value;
					if(lan=="HI" || lan=="BN" || lan=="AR" || lan=="ZH" || lan=="GU" || lan=="KO" ||lan=="JA" || lan=="ML"|| lan=="MI" || lan=="NE" || lan=="MN" || lan=="PA" || lan=="MR" || lan=="TA" || lan=="TO" ||lan=="BO" || lan=="UR"){
						csInterface.evalScript("printTranslation('"+ this.responseText + "','" + i + "')");
					}
					else
					{
						csInterface.evalScript("translation('"+ this.responseText + "','" + i + "')");
					}
					
				}
				else
					csInterface.evalScript("alert('Server error: " + this.status + "')");
			};
			xhr.send(da);
		}
		csInterface.evalScript("alert('Translation Complete!')");
	});
	setTimeout(function(){
            			csInterface.evalScript("check()", function(data)
            			{
							if(data==1)
							{
								csInterface.evalScript("alert('" + this.data + "')");
							}
							else{
								csInterface.evalScript("alert('" + this.data + "')");
								csInterface.evalScript("alert('nothing')");
							}

            			});
					  }.bind(this), 1000);
	
}
