jQuery对不同元素的不同事件触发相同的功能

Question

What if different elements have to trigger the same function but on different events ?

$('#btnNext').on('click', function() { /*Same thing*/ });

$('#txtField').on('change blur', function() { /*Same thing*/ });

Is there any way to integrate these two lines, so I can write the same lines of code just once ?

Answer 1

You included a clue in your question: "trigger the same function" - so simply bind the same function:

function commonHandler(e) { /* your code */ }

$('#btnNext').on('click', commonHandler);

$('#txtField').on('change blur', commonHandler);

Answer 2

$('#btnNext').on('click', myMethod );

$('#txtField').on('change blur',  myMethod );

function myMethod()
{
/*Your Code goes here*/
}
