Description
Although the following code works as expected at first, pressing return multiple times in quick succession causes a crash.
var win = Ti.UI.createWindow({
fullscreen: false,
exitOnClose: true
});
var view = Ti.UI.createWebView({
html: "<html><body>Empty</body></html>"
});
var text = Ti.UI.createTextArea({
top: 50,
width:'100%',
height: 50
});
text.addEventListener('return', function() {
view.evalJS('document.body.innerHTML = "' + text.value + '"');
text.value = "";
setTimeout(function() {
text.focus();
}, 500);
});
win.add(view);
win.add(text);
win.open();
text.focus();
e.addEventListener('return', function(e) {
view.evalJS('document.body.innerHTML = "' + text.value + '"');
e.value = "";
setTimeout(function() {
e.focus();
}, 500);
});
