    <p>I'm super new to jquery and just stractching the surface of its awesomeness so sorry if this is a really basic question but I have a button on my site that once clicked posts some data to my server and I'm wondering how to provide jquery with data I want to be posted. I have made jquery refreshless forms but they have required the user to enter something which I post but now I want to send some data that is not entered or available on the webpage.</p> <p>On my site, I have a button to click on if you want to 'follow' a topic. If you follow a topic I need to send a topic_id and your user id to my server to start the process but I think putting this on my web page for jquery to capture would be confusing to users(if I can't pass variables I plan to do this approach but hide the fields). The userid/topicid is avaiable to my template engine but I'm unsure how to pass the data over to the script.</p> <p>Here's a example of my script html:</p> <pre><code>&lt;input type='button' value='Follow' id='btnFollow'&gt; </code></pre> <p>follow.js:</p> <pre><code>$(document).ready(function () { $('#btnFollow').click(function() { //$("#btnFollow").prop('value', 'Following'); if ($(this).val() == 'Follow') { $("#btnFollow").prop('value', 'Following') } else if ($(this).val() == 'Following') { $("#btnFollow").prop('value', 'Follow') $.ajax({ type: 'POST', url: '/follow_modification', async: true, data: { fe1: "test" }, complete: function(xmlRequestObject, successString){ ymmReceiveAjaxResponse(xmlRequestObject, successString); } }); } }) }); </code></pre> <p>How do I get info into the function from the html? So far all my javascripts have been triggered by clicks and then take data from the page.. if I have a variable in my template called {{ user_id }} how can I pass that to the script so when a click triggers a action then it'll have the data it needs to post?</p>

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.
