Hello,

i can not use a Var in a Eventlistener and onload-function. I get an Application Error:

Can`t find variable: eintrag at parse-json-suchen.js

Here is my Code

search_leutesuchen.addEventListener('change', function(e){
 
    var url = "http://www.urltosomething.com/suche.php";
    var tableData_leutesuchen = [];
    var json, eintraege, eintrag, i, row;
 
    var xhr = Titanium.Network.createHTTPClient({
        onload: function(e) {
 
            Ti.API.info('response: '+ this.responseText);
            json = JSON.parse(this.responseText);
            for (i = 0; i < json.eintraege.length; i++) {
 
                eintrag = json.eintraege[i];
 
                Ti.include('lib/parse-json-suchen.js');
 
                tableData_leutesuchen.push(row);
 
            }
 
        table_leutesuchen.setData(tableData_leutesuchen);            
 
        },
        onerror: function(e) {
            L('error');
        },
        timeout:10000
    });
 
    var params = {  
        'uid': Titanium.Platform.id,  
        'query': e.value,
        'task': 'sucheleutenick'
    }; 
 
    xhr.open("POST", url);
    xhr.send(params);
 
});

And my Code on the included-file (parse-json-suchen.js)

row = Ti.UI.createTableViewRow({
                    height:'80dp',
                    backgroundColor: 'transparent',
                    hasChild: true, 
                    test:'profil.js'
                });
 
                nameLabel = Ti.UI.createLabel({
                        text: eintrag.name,
                        font:{
                            fontSize:'20dp',
                            fontWeight:'bold'
                    },
                    height:'auto',
                    left: 80,
                    top:'15',
                    color:'#000',
                    touchEnabled:false
                });
 
                if(eintrag.geschlecht == 'w'){ var sex = 'weiblich'; }
                if(eintrag.geschlecht == 'm'){ var sex = 'männlich'; }
 
                 sloganLabel = Ti.UI.createLabel({
                        text: sex + ', ' + eintrag.alter,
                        font:{
                            fontSize:'16dp'
                    },
                    height:'auto',
                    left: 80,
                    top:'45',
                    color:'#000',
                    touchEnabled:false
                });
 
 
                if(eintrag.mbild == ''){
                    if(eintrag.geschlecht == 'w'){ var bildi = 'icons/frau.png'; }
                    if(eintrag.geschlecht == 'm'){ var bildi = 'icons/mann.png'; }
                } else {
                    var bildi = "http://www.someurl.com/mitglied/" + eintrag.mid + "/" + eintrag.mbild;
                }
                //Ti.API.info(bildi);
                var bild =  Titanium.UI.createImageView({
                        image: bildi
                });
 
                if(eintrag.mbild == ''){
 
                    bild.left = 15;
                    bild.top = 25;
                    bild.width = 24; //wichtig für Android
 
                } else {
 
                    bild.left = 10;
                    bild.top = 10;
 
                    bild.width = 50;
                    bild.height = 50; 
                }
 
                row.add(bild);
 
 
 
                //Alle Daten von jSON
                row.mid = eintrag.mid;
                row.name = eintrag.name;
                row.mbild = eintrag.mbild;
                row.bezstatus = eintrag.bezstatus;
                row.uebermich = eintrag.uebermich;
                row.alter = eintrag.alter;
                row.geschlecht = sex;
 
 
                row.add(nameLabel);
                row.add(sloganLabel);

When I dont include all works fine. When I dont use a eventListener with a onload-function it works fine, too.

Any hints or solutions?

Cheers Fabian

untested, but try to include the parse-json-suchen.js only once and wrap everything in that file into a function. In the for loop just call the function - like:

var xhr = Titanium.Network.createHTTPClient({ onload: function(e) { Ti.API.info('response: '+ this.responseText); json = JSON.parse(this.responseText); Ti.include('lib/parse-json-suchen.js'); for (i = 0; i < json.eintraege.length; i++) { eintrag = json.eintraege[i]; var row=myFunction(eintrag); tableData_leutesuchen.push(row); } ... ...
and in your parse-json-suchen.js wrap everything in a function called myFunction:
function myFunction(eintrag){ //your complete code here return row; }

I have found a solution by myself. When i put this hole code above in an includes-file it works!

var tableData_leutesuchen = [];
    var json, eintraege, eintrag, i, row;
 
    var xhr = Titanium.Network.createHTTPClient({
        onload: function(e) {
 
            Ti.API.info('response: '+ this.responseText);
            json = JSON.parse(this.responseText);
            for (i = 0; i < json.eintraege.length; i++) {
 
                eintrag = json.eintraege[i];
 
               // etc bla bla ...
               // etc bla bla ...
               // etc bla bla ...
               // etc bla bla ...
               // etc bla bla ...
               // etc bla bla ...
 
 
 
                tableData_leutesuchen.push(row);
 
            }
 
        table_leutesuchen.setData(tableData_leutesuchen);            
 
        },
        onerror: function(e) {
            L('error');
        },
        timeout:10000
    });
