i have this form and im trying to get the value from the text area. for some reason it doesn't want to.
<form action="/profile/index/sendmessage" method="post" enctype="application/x-www-form-urlencoded">
<div class="upload_form">
<dt id="message-label"><label class="optional" for="message">Enter Message</label></dt>
<dd id="message-element">
<textarea cols="60" rows="5" id="message" name="message"></textarea></dd>
<dt id="id-label"> </dt>
<dd id="id-element">
<input type="hidden" id="id" value="145198" name="id"></dd>
<dt id="send_message-label"> </dt>
<dd id="send_message-element">
<input type="submit" class="sendamessage" value="Send" id="send_message" name="send_message"></dd>
</div>
</form>
$("input.sendamessage").click(function(event) {
event.preventDefault();
var message = $('textarea#message').html();
var id = $('input#id').val();
console.log(message + '-' + id);
});
or jsfiddle
any ideas?
Value of textarea is also taken with val method:
var message = $('textarea#message').val();
You need to use .val() for textarea as it is an element and not a wrapper. Try
$('textarea#message').val()
you should use val() instead of html()
var message = $('#message').val();
in javascript :
document.getElementById("message").value
You don't need to use textarea#message
var message = $('textarea#message').val();
You can directly use
var message = $('#message').val();
You should check the textarea is null before you use val() otherwise, you will get undefined error.
if ($('textarea#message') != undefined) {
var message = $('textarea#message').val();
}
Then, you could do whatever with message.
$('textarea#message') cannot be undefined (if by $ you mean jQuery of course).
$('textarea#message') may be of length 0 and then $('textarea#message').val() would be empty that's all
You don't need to use .html(). You should go with .val().
From the doc of .val():
The
.val()method is primarily used to get the values of form elements such asinput,selectandtextarea. When called on an empty collection, it returnsundefined.
var message = $('#message').val();
You can directly use
var message = $.trim($("#message").val());
Read more @ Get the Value of TextArea using the jQuery Val () Method
You can also get value by name instead of id like this:
var message = $('textarea:input[name=message]').val();
all Values is always taken with .val().
see the code bellow:
var message = $('#message').val();
