addeventlistener多个功能

Question

我试图让这段代码发挥作用。程序只读取前两个函数的问题，因为它们在同一个网页中。当我移动到另一个时，没有读取其他功能。有什么帮助吗？

   function addListeners(){
    if(window.addEventListener){
        var elements=['question','pregunta','express','login','repassword'];
        var events=['keyup','submit','click','submit','submit'];
        var functions=[press,validateQuestion,validateExpress,validateLogin,validateRepassword];
        for(var i=0;i<elements.length;i++)
        {
            document.getElementById(elements[i]).addEventListener(events[i],functions[i],false);
        }
    } else if(window.attachEvent){ // Add for Internet Explorer previous to IE9
        var elements=['question','pregunta','express','login','repassword'];
        var events=['onkeyup','onsubmit','onclick','onsubmit','onsubmit'];
        var functions=[press,validateQuestion,validateExpress,validateLogin,validateRepassword];
        for(var i=0;i<elements.length;i++)
        {
            document.getElementById(elements[i]).attachEvent(events[i],functions[i]);
        }
    }   
    //Add functions
    function press()
    {
        var canti=document.getElementById('question').value.length;
        var disponibles=150-parseInt(canti);
        document.getElementById('cantidad').innerHTML=disponibles;
    }
