Solution to the problem that JQuery cannot listen to the keyup event of input under ff_jquery

Copy code The code is as follows:

$(document).ready(function(){
$('#news_title').bind('input',fun).bind('keyup',fun);
});

//function list
var fun=function(){
value=$(this).val();
$('.prev').text(value);
}

Note:

bind('input',fun) is used for keyup under ff

bind('keyup',fun) for ie
