    function playController(dataObj){

    function playHandlers(){

    $(document).ready(playHandlers);

无论是否单击对象,此代码段都会在页面加载时触发。为什么?

最佳答案

您想要的是:

function playController(dataObj){
    alert(dataObj);
}

function playHandlers(){
    var dataObj = "stef";
    $('.audiocontrol').on('click', function() { playController(dataObj); } );
}

$(document).ready(playHandlers);


编写代码的方式是在playController调用中注册时调用.on
