javascript - Difference between "change" and "input" event for an `input` element

Question

Can someone tell me what the difference between the change and input events is?

I am using jQuery for adding them:

$('input[type="text"]').on('change', function() {
    alert($(this).val());
})

It also works with input instead of change.

Maybe some difference in the event ordering relative to focus?

According to this post:

• oninput event occurs when the text content of an element is changed through the user interface.

• onchange occurs when the selection, the checked state or the contents of an element have changed. In some cases, it only occurs when the element loses the focus or when pressing return (Enter) and the value has been changed. The onchange attribute can be used with: <input>, <select>, and <textarea>.

TL;DR:

• oninput: any change made in the text content
• onchange:
  • If it is an <input />: change + lose focus
  • If it is a <select>: change option

$("input, select").on("input", function () {
    $("pre").prepend("
On input. | " + this.tagName + " | " + this.value);
}).on("change", function () {
    $("pre").prepend("
On change | " + this.tagName + " | " + this.value);
}).on("focus", function () {
    $("pre").prepend("
On focus | " + this.tagName + " | " + this.value);
}).on("blur", function () {
    $("pre").prepend("
On blur | " + this.tagName + " | " + this.value);
});
