    <p>I have read so many questions about this issue and I can't find an answer.</p> <p>All I want to do (which I thought would be the simplest thing ever in 2011) is get some info from my database with jquery and ajax and save it in a variable to later do some stuff with it. 5 hours later I'm still here. Is this impossible to do?</p> <p>The typical examples for this are:</p> <pre><code>$.post("test.php", { name: "John", time: "2pm" }, function(data) { alert("Data Loaded: " + data); }); </code></pre> <p>and </p> <pre><code>$.post("test.php", { name: "John", time: "2pm" }, function(data) { $("somediv").html(data); }); </code></pre> <p>So that works great... if you'll just use the value now and forget about it.</p> <p>Now I don't want to display the information on the page or in an alert box, I just want to save it in some variable so I can do some calculations later.</p> <p>when I assign data to variables, the values are always lost. After reading a bunch of answers about this, apparently there's no way to return data because this function is async and works differently and we don't understand how it works, etc.</p> <p>For example I tried this:</p> <p><a href="https://stackoverflow.com/questions/3080003/return-data-from-jquery-post">return data from jquery $.post</a></p> <p>But that didn't work for me. Or I didn't understand it correctly, is this an explanation or an example? Am I suppose to type callback or should I replace it with something?</p> <p>Some people said call another function like here:</p> <p><a href="https://stackoverflow.com/questions/3556080/jquery-return-post-data">Jquery return post data</a></p> <p>That didn't work either, data was passed to the function, i could use it there but again if I saved it in a variable it got lost and there was no way to return the function since where do I get what the function returns?</p> <p>Finally I said you know what, I'll just put the value in a hidden field and then I'll access it. That didn't work either, I can put the value in the field but when I try to access it... it's not there yet.</p> <p>Should I not use $.post? Does $.ajax make a difference? How can I accomplish this? Is it really so hard to ajax-get a value from the database and save it in javascript for later? Does everybody just use it right away? Is this really this hard to achieve?</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.
