Is this what you mean?

JavaScript:

function preventDot(id)
{
    str = document.getElementById(id).value;
    document.getElementById(id).value = (str.replace(".",""));  
}

HTML:

<input type="text" id="input" onkeyup="preventDot(this.id)" />

Bind an event to your input tag

<input type="text" onkeypress="return preventDot(event);" />

Then create a function like preventDot that will return false and prevent the key from being entered if the . key is pressed

function preventDot(e)
{
    var key = e.charCode ? e.charCode : e.keyCode;

    if (key == 46)
    {
        return false;
    }    
}
