// Function to change the content of t2  
function modifyText() {  
 var t2 = document.getElementById("t2");  
 t2.firstChild.nodeValue = "three";      
}  

// add event listener to t  
var el = document.getElementById("t");   
el.addEventListener("click", modifyText, false);   
el.addEventListener('click', function(){console.log('12313')}, false)

绑定到el上的click事件都可以执行
