Well, I need to get the value of a textarea and send it to a second textarea on the same page, but when I refresh I do not want the value to come from the second textarea sum, how to do this using javascript and Ajax? >
My Code
var textArea = getDOMElement("textarea", "class", "logarea", 0)
var y = textArea.value;
var x = document.createElement("TEXTAREA");
var t = document.createTextNode(y);
x.appendChild(t);
document.getElementsByClassName("span8 center")[0].appendChild(x);
Use autoSave - A jQuery Plugin
<textarea class="form-control" rows="6" id="idTextArea" placeholder="digite aqui ..."></textarea>
<script>
/*
jQuery autoSave v1.0.0 - 2013-04-05

(function(a){a.fn.autoSave=function(d,e){return this.each(function(){var b=0,c=a(this),f=e||1E3;c.keyup(function(){clearTimeout(b);var a=c.val();localStorage&&localStorage.setItem("autoSave",a);b=setTimeout(function(){d()},f)})})}})(jQuery);
var demoText = $("#idTextArea");
if (localStorage) {
var content = localStorage.getItem("autoSave");
if (content) {
demoText.text(content);
}
}
</script>
Cookies
Cookies are data stored in small text files on your computer.
When a Web server sends a Web page to a browser, the connection is terminated and the server forgets everything about the user.
Cookies were invented to solve the problem "how to remember information about the user":
When a user visits a web page, their name can be stored in a cookie. The next time the user visits the page, the cookie "remembers" your name. Cookies are saved in name and value pairs, such as:
document.cookie = "username=John Doe";
You can save the value of your textArea to the localStorage which is just like your na- tional database.
localStorage.setItem('textArea', y);
So whenever you load the page you can fetch the value in the localStorage and fill in your field:
x.value = localStorage.getItem('textArea');
