detecting change in a text input box using jquery/javascript

Question

in html and javascript, I can use keyup, focus, blur to detect most of the content changes in a text input, however if the user do a copy and paste into the text input, how do I capture this change? The issue here is that the input is already in focus when user paste into it.

Answer 1

You could capture the paste event ( http://www.quirksmode.org/dom/events/cutcopypaste.html )

$("#myinput").bind("paste",function(){
    //code here
})

Answer 2

$("#myinput").change(function(){
    // whatever you need to be done on change of the input field
});

// Trigger change if the user type or paste the text in the field
$("#myinput").keyup(function(){
    $(this).change();
});

// if you're using a virtual keyboard, you can do :
$(".key").live('click',function(){
    $("#myinput").val($("#myinput").val()+$(this).val());
    $("#myinput").change(); // Trigger change when the value changes
});

Answer 3

文本框有一个OnChange事件，当a）文本框失去焦点并且文本框中的值发生变化时触发该事件。
