I have a jquery token tagit plugin and I want to bind to the paste event to add items correctly.
I'm able to bind to the paste event like so:
.bind("paste", paste_input)
...
function paste_input(e) {
console.log(e)
return false;
}
How can I obtain the actual pasted content value?
There is an onpaste event that works in modern day browsers. You can access the pasted data using the getData function on the clipboardData object.
$("#textareaid").bind("paste", function(e){
// access the clipboard using the api
var pastedData = e.originalEvent.clipboardData.getData('text');
alert(pastedData);
} );
Note that bind and unbind are deprecated as of jQuery 3. The preferred call is to on.
All modern day browsers support the Clipboard API.
See also: In Jquery How to handle paste?
var pastedData = line: Uncaught TypeError: Cannot read property 'getData' of undefined. You need to change e.clipboardData to e.originalEvent.clipboardData. I suspect because jquery is wrapping the actual paste event in an event of its own--don't quote me on that though.
e.originalEvent.clipboardData.getData('text/plain') worked for me
window.clipboardData.getData('text')
paste and input events, set a flag on paste event handler, and check for that flag in the input event handler. In it, the this.value is the value pasted, and this works in IE11.How about this: http://jsfiddle.net/5bNx4/
Please use .on if you are using jq1.7 et al.
Behaviour: When you type anything or paste anything on the 1st textarea the teaxtarea below captures the cahnge.
Rest I hope it helps the cause. :)

How do you handle oncut, oncopy, and onpaste in jQuery?
EDIT:
Events list within .on() should be space-separated. Refer https://api.jquery.com/on/
code
$(document).ready(function() {
var $editor = $('#editor');
var $clipboard = $('<textarea />').insertAfter($editor);
if(!document.execCommand('StyleWithCSS', false, false)) {
document.execCommand('UseCSS', false, true);
}
$editor.on('paste keydown', function() {
var $self = $(this);
setTimeout(function(){
var $content = $self.html();
$clipboard.val($content);
},100);
});
});
undefined for few days innit :P
I recently needed to accomplish something similar to this. I used the following design to access the paste element and value. jsFiddle demo
$('body').on('paste', 'input, textarea', function (e)
{
setTimeout(function ()
{
//currentTarget added in jQuery 1.3
alert($(e.currentTarget).val());
//do stuff
},0);
});
Another approach:
That input event will catch also the paste event.
$('textarea').bind('input', function () {
setTimeout(function () {
console.log('input event handled including paste event');
}, 0);
});
$(document).ready(function() {
$("#editor").bind('paste', function (e){
$(e.target).keyup(getInput);
});
function getInput(e){
var inputText = $(e.target).html(); /*$(e.target).val();*/
alert(inputText);
$(e.target).unbind('keyup');
}
});
This work on all browser to get pasted value. And also to creating common method for all text box.
$("#textareaid").bind("paste", function(e){
var pastedData = e.target.value;
alert(pastedData);
} )
You could compare the original value of the field and the changed value of the field and deduct the difference as the pasted value. This catches the pasted text correctly even if there is existing text in the field.
function text_diff(first, second) {
var start = 0;
while (start < first.length && first[start] == second[start]) {
++start;
}
var end = 0;
while (first.length - end > start && first[first.length - end - 1] == second[second.length - end - 1]) {
++end;
}
end = second.length - end;
return second.substr(start, end - start);
}
$('textarea').bind('paste', function () {
var self = $(this);
var orig = self.val();
setTimeout(function () {
var pasted = text_diff(orig, $(self).val());
console.log(pasted);
});
});
It would appear as though this event has some clipboardData property attached to it (it may be nested within the originalEvent property). The clipboardData contains an array of items and each one of those items has a getAsString() function that you can call. This returns the string representation of what is in the item.
Those items also have a getAsFile() function, as well as some others which are browser specific (e.g. in webkit browsers, there is a webkitGetAsEntry() function).
For my purposes, I needed the string value of what is being pasted. So, I did something similar to this:
$(element).bind("paste", function (e) {
e.originalEvent.clipboardData.items[0].getAsString(function (pStringRepresentation) {
debugger;
// pStringRepresentation now contains the string representation of what was pasted.
// This does not include HTML or any markup. Essentially jQuery's $(element).text()
// function result.
});
});
You'll want to perform an iteration through the items, keeping a string concatenation result.
The fact that there is an array of items makes me think more work will need to be done, analyzing each item. You'll also want to do some null/value checks.
I do it like so, this would work on most browsers used by humans
$("#couponCode").bind("change keyup input paste",function () {
const value= document.getElementById("couponCode").value;
});
