Appcelerator Titanium中的TextField Valdiation

Question

我如何在Titanium或JavaScript中对我的TextField进行Valdiate以将其限制为仅限数字.

var txt_appt2 = Titanium.UI.createTextField({
    top:2,
    left:240,
    width:75,
    color:'#000',
    backgroundColor:'#fff',
    font: {fontSize: 12}
});

Answer 1

txt_appt2.addEventListener('change',function(e){
    txt_appt2.value = txt_appt2.value.replace(/[^0-9]+/,"");
});

Answer 2
