为一个复选框调用2个JavaScript函数

Question

I've got a little problem, my checkbox already has an ID, Name etc. attached to it, so I don't know how to link the JavaScript code below to the checkbox, because the ID and Name are already used. I already know that you cannot use multiple IDs, because it will then only use the first ID specified.

Any ideas how to fix this?

 setTimeout(function(){ document.getElementById('checkboxdelay').checked = true; },1000) 

 <input name="product" value="199" type="checkbox" id="p4" id="checkboxdelay" onChange="totalIt()"/> 

Answer 1

You don't have to select one element in different ways to attach different javascript code, But if you want to call it in a different way you can always assign a class to it and identify element with javascript method: document.getElementsByClassName('classname')

 setTimeout(function(){ document.getElementsByClassName('checkboxdelay')[0].checked = true; },1000) 

 <input name="product" value="199" type="checkbox" id="p4" class="checkboxdelay" onChange="totalIt()"/>
