Fire onChange event on input type number with Jquery

Question

I have input with type number:

<input type="number" id="input-number" onChange="DoSomething();"/>

How to fire onChange event with jQuery?

[EDIT]

Did it with following code:

$("#input_0").trigger("change");

Answer 1

With trigger

Any event handlers attached with .on() or one of its shortcut methods are triggered when the corresponding event occurs. They can be fired manually, however, with the .trigger() method. A call to .trigger() executes the handlers in the same order they would be if the event were triggered naturally by the user:

console.clear()
DoSomething = (e) => {
  console.log(e.target)
}

$('#input-number').trigger('change')

<input type="number" id="input-number" onChange="DoSomething(event);"/>

Answer 2

Please have a look attached example.

You need to setup the jquery function ($(selector).change()) which is fired when lost the focus from textbox.

$("#input-number").on('change',function(){
  alert($(this).val());
})

<input type="number" id="input-number"/>
