那么你应该阅读更多关于addEventListener(标准)和attachEvent(IE)
//assume element means the button
//you can use getElementsByTagName, getElementsByClassName, querySelectorAll etc.
//to fetch your elements
//DRY, store the operation in a function so it's reusabe and not written twice
function thisFunction(){
AddToCart(document.getElementById('toy_title1').innerHTML,
document.getElementById('toy_quantity1').value,
document.getElementById('toy_price1').innerHTML)
}
if(element.addEventListener){ //check if the standard is supported
element.addEventListener('click',function(){ //use it to add the handler
thisFunction();
});
} else {
element.attachEvent('onclick',function(){ //else, we use IE's version
thisFunction();
}, false);
