How to modify clipboard paste data on Chrome
I meet a requirement,the user can copy data from any other resources(such as word,excel,notepad++),and then paste it to my web page,the application must be run on Chrome. I have to modify the paste data if it contains some invalid data.
I tried clipboardData.setData but it only work on IE,below is my code:
<script type="text/javascript">
var elEditor = document.getElementById("editor");
elEditor.addEventListener('paste', function(e){
var clipboardData = e.clipboardData || e.originalEvent.clipboardData || window.clipboardData;
var text = clipboardData.getData('Text');
console.log("---before:t"+text);
text = text.replace(/d+/,new Date().getTime());
//don't change the pasted data on Chrome page!That's the key point make it fail
clipboardData.setData('Text',text);
console.log("---after:t"+text);
return false;
});
</script>
I can see the data in Chrome console changed,but in the web page,the data is still not changed!Can anyone help me?
If not use clipboardData.setData,is there any other ways can do the same thing?
Thank in advance!

For the 'paste' event, you need to change the content of the field, because the paste has already happened;
Example: https://jsfiddle.net/o2gxgz9r/75276/
$('.cpf_cnpj').each(function(){
$(this).on('paste', function(e){
var clipboardData = e.clipboardData || e.originalEvent.clipboardData || window.clipboardData;
if (clipboardData){
var text = clipboardData.getData('text');
text = text.replace(/./g, '').replace(/-/g, '').replace(///g, '');
e.target.value = text;
e.preventDefault();
}
});
});
