How to prevent from entering decimals and negatives in the Ext textfield-- Extjs

I have a textfield that is accepting large input numbers. My issue is if I use Ext.form.NumerField({}) the large numbers gets converted into 1e notation and hence I'm unable to fix this with toFixed(). Hence I switched to using Ext.form.TextField({}). However with textfield I want to prevent user from entering decimal numbers, negative numbers and allow only numeric fields. For only numeric I can use regex: var regex = /[0-9.]/,. // will only allow numeric values But I'm not sure how can I get all the above conditions(no decimals and no negative) in the regex.

any help on regex will be appreciated.

Thanks

If you want to just validate the input, use the following regex: 

/^\d+$/

but, if you prevent typing, add this on the text field:

    enableKeyEvents:true,
    listeners:{
            keydown : function(t,e) {
            var code = e.browserEvent.keyCode;
            console.log(code);     
            if ((code < 48 || code > 57) &&(code !== 8)){
                e.stopEvent();
            }
        }
    },
