    <p>I've been trying various methods to get a form to submit when hitting the enter key. I know it works with an input field, but because this is going to be a comment, it needs to be a text area. </p> <p>This is what I currently have for the form to submit with a button. </p> <pre><code>$('.messageSubmit').live('click', function(){ var name = $(this).siblings('.messageTextarea').val(); var theid = $(this).attr('data-the_id'); var dataString = name; $.ajax({ dataType: 'json', url: "https://api.instagram.com/v1/media/"+$(this).attr('data-the_id')+"/comments?"+hash, type: "POST", data: "text="+dataString, success: function(data) { // finish load console.log(data, dataString, 'fail'); }, error: function(data) { var username = JSON.parse(localStorage.getItem('iguser')); var profilepic = JSON.parse(localStorage.getItem('iguserimg')); //console.log(data, dataString, 'succ'); $('.box[data-the_id="' + theid + '"]').children('.postMessage').children('.messageComments').append('&lt;li&gt;&lt;img class="commentUserImg" src="' + profilepic + '"&gt;&lt;div class="commentUser"&gt;' + username + '&lt;/div&gt;&lt;div class="commentText"&gt;' + dataString + '&lt;/div&gt;&lt;/li&gt;'); $('.messageTextarea').val(''); // Remove comment from TextArea } }); return false; }); </code></pre> <p>It works like it should. I want to remove the submit button and just have the form submit when a user hits the enter key. I know some people advise against this, but the users on this website will be used to hitting enter from Facebook and such. </p> <p>I've tried methods such at this, but it none seem to work. </p> <pre><code>$('.messageTextarea').keydown(function() { if (event.keyCode == 13) { this.form.submit(); return false; } }); </code></pre> <p>Here is my form code</p> <pre><code>&lt;form&gt; &lt;textarea class="messageTextarea" onfocus="if(this.value==this.defaultValue)this.value=\'\';" onblur="if(this.value==\'\')this.value=this.defaultValue;"&gt;Write your comment here...&lt;/textarea&gt; &lt;input type="submit" data-the_id="' + theid + '" name="submit" class="messageSubmit" id="submit_btn" value="Submit your comment"&gt; &lt;/form&gt; </code></pre> <p>Any help would be great. Also, if anyone knows how to add an if function that will prevent the form from submitting with the current default value in the Textarea, that would be awesome. Currently, with how the textarea is set up now, if you just hit submit, it will submit <em>Write your comment here...</em></p> <p>Thanks</p> <p><strong>EDIT: Could a work around be... Having an button to submit, like normal, but have it hidden, and when you hit enter it triggers a call for that button? But then... I'd run into the same problem of enter doing nothing in the textarea except break into a new line...</strong></p>

    1. COIt's never a good idea to modify the way common elements function. Users will expect that textarea allows using the enter key. Then again, stack overflow does this so... grain of salt

    2. COThat was how I first approached this problem, but the only users on this site will be those of instagram and facebook. I figured they'd know what to do when seeing a comment field.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
