Question

Select the top input, and then tab to the second. It will put your cursor at the end of the value, rather than selecting all. if you remove the javascript and run again, you can see this behavior doesnt happen.

Clueless.

Answer 1

$(function() {
    $('.numbersOnly').keyup(function (evt) {
        if ($.inArray(evt.which, [37, 38, 39, 40]) != -1) return false;
            this.value = this.value.replace(/[^\d\.]/g,'');
            if (evt.which == 9) this.select(); //<-- re-select field value
    });
});

Some other modifications I made:

• pattern made shorter (using \d alias)
• cursor keys are re-enabled (in your code they were blocked from working)
• the selection happens only if the tab key was pressed, not merely any key
