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.
The change() is an inbuilt method in jQuery that is used to detect the change in value of input fields. This method works only on the “<input>, <textarea> and <select>” elements.
Answer: Use the input Event You can bind the input event to an input text box using on() method to detect any change in it.
Use any or all of them onchange event, onpropertychange event, onkeyup event, onpaste event and oninput event in the input element and call a function to see the effect. click outside of it to see.
You could capture the paste event (http://www.quirksmode.org/dom/events/cutcopypaste.html)
$("#myinput").bind("paste",function(){
//code here
})
$("#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
});
the textbox has an OnChange event that fires when a) the text box loses focus AND the value within the text box has changed.
