The error message "Uncaught TypeError: Unable to retrieve the 'length' property of an undefined object in Titanium" has occurred

Here is the data I am working with:

{"todo":[{"todo":"Khaleeq Raza"},{"todo":"Ateeq Raza"}]}

This is my current code snippet:


var dataArray = [];
var client = new XMLHttpRequest();
client.open("GET", "http://192.168.10.109/read_todo_list.php", true);
client.send();

client.onreadystatechange = function() {
    json = JSON.stringify(client.response); // convert to JSON
    var get = console.log(JSON.parse(json));

    for (var i = 0; i < get.length; i++) { 
        var row = Ti.UI.createTableViewRow({
            title: get[i].todo,
            hasChild: true,
        });
        dataArray.push(row);
    }

    $.tableView.setData(dataArray);
};

I encountered this error message:

Uncaught TypeError: Cannot read property 'length'

How can I resolve this issue?

Answer №1

It seems like you are attempting to retrieve the JSON object as an array.

Consider adjusting this line:

for( var i=0; i<get.length; i++){

to:

for( var i=0; i<get["todo"].length; i++){

By making this change, you should be able to access the data, assuming it is consistently available and formatted correctly.
