    <p>I just started learning HTML and HTML5 recently. My site involves different audio players playing different tunes/mp3s. At the moment I have created different id names for each audio player and each play/pause and stop button.</p> <p>My JavaScript file to play this has unnecessary repetitions of similar code. I guess there is a better way to do this using variables so the code is not repeated with different id names but I am not too familiar with JavaScript.</p> <p>Here's what a snippet of my JavaScript file looks like. </p> <pre><code>$(document).ready(function(){ $("#play-bt1").click(function(){ $("#audio-player1")[0].play(); $("#message").text("Music started"); }) $("#pause-bt1").click(function(){ $("#audio-player1")[0].pause(); $("#message").text("Music paused"); }) $("#stop-bt1").click(function(){ $("#audio-player1")[0].pause(); $("#audio-player1")[0].currentTime = 0; $("#message").text("Music Stopped"); }) }) $(document).ready(function(){ $("#play-bt2").click(function(){ $("#audio-player2")[0].play(); $("#message").text("Music started"); }) $("#pause-bt2").click(function(){ $("#audio-player2")[0].pause(); $("#message").text("Music paused"); }) $("#stop-bt2").click(function(){ $("#audio-player2")[0].pause(); $("#audio-player2")[0].currentTime = 0; $("#message").text("Music Stopped"); }) }) $(document).ready(function(){ $("#play-bt3").click(function(){ $("#audio-player3")[0].play(); $("#message").text("Music started"); }) $("#pause-bt3").click(function(){ $("#audio-player3")[0].pause(); $("#message").text("Music paused"); }) $("#stop-bt3").click(function(){ $("#audio-player3")[0].pause(); $("#audio-player3")[0].currentTime = 0; $("#message").text("Music Stopped"); }) }) </code></pre> <p>and here is the corresponding part of my HTML file</p> <p></p> <pre><code>&lt;div class="grid_4 alpha"&gt;

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.
