Answer 1

var text = "";

jQuery("textarea.message").each(function(){
   text += jQuery(this).val() + "\n";
})

Answer 2

尝试thought = $('textarea').text()我认为这应该工作或thought = $('.message').text();

Answer 3

Use the each() method.

jQuery("a#send-thoughts").click(function() {
    jQuery("textarea.message").each(function() {
        var thought= $(this).val();
        alert(thought);
    });
 });​

Check the online doc for more information: http://api.jquery.com/each/

Answer 4

<pre>
<a id="send-thoughts" href="">Click</a>
<textarea id="message1" class="message1">Hello</textarea>
<textarea id="message2" class="message2">World</textarea>
</pre>

jQuery:

jQuery("a#send-thoughts").click(function() {
                var thought1= jQuery("textarea.message1").val();
                alert(thought1);
                var thought2= jQuery("textarea.message2").val();
                alert(thought2);
 });​

Answer 5

.val() , like all the jQuery getters, returns the value of the first matched form-input element. You will have to use a .each() loop and concatenate the values:

jQuery("a#send-thoughts").click(function() {
    var thought = '';
    jQuery("textarea.message").each(function() {
        thought += $(this).val() + ' ';
    });
    alert(thought);
});​
