Well no, the handler could test the sort/type of input on execution.

<input class='sort123' onblur='doIt(this)' ..
<input class='sort456' onblur='doIt(this)' ..

const doIt = (t) => {
    	if (t.className == 'sort123') alert(t.value.toUpperCase());
    	if (t.className == 'sort456') alert('456');
    	// ..... or do nothing
};
