    <p>This may be really simple but I'm not all that familiar with jQuery selectors.</p> <p>Here's the HTML with inline css:</p> <pre><code>&lt;div id="login" style="position:relative; display:none; top:0px; left:0px; right:0px; bottom:0px; text-align:center; vertical-align:middle; z-index:10;" class="trwhole"&gt; &lt;table width="100%" height="100%"&gt; &lt;tr width="100%" height="100%"&gt; &lt;td width="100%" height="100%" style="vertical-align:middle; text-align:center;"&gt; &lt;img src="images/MemorizeItWhite.png" z-index="10000" style="width:290px;"&gt; &lt;table align="center" class="w290"&gt; &lt;tr&gt; &lt;td&gt; &lt;div id="lerror" class="alert"&gt;&lt;/div&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td align="left"&gt;Username: &lt;br&gt; &lt;input autocorrect="off" autocapitalize="off" type="text" placeholder="username" id="username" style="" class="ui-corner-all w290"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td align="left"&gt;Password: &lt;br&gt; &lt;input type="password" placeholder="password" id="password" style="" class="ui-corner-all w290" onkeypress="if (event.keyCode==13){login();}"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt; &lt;input type="button" id="loginBt" onclick="login();" value="Log In" class="submit" style="width:85px;"&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/div&gt; </code></pre> <p>I'm looking for something like </p> <pre><code>$("select tr that contains input[placeholder] in #login or #signup2") .on("touchstart", function () { $("this &gt; input").focus(); }); </code></pre> <p>The point is to give each an <code>ontouchstart</code> attribute changing focus to the input within it, if that input has a placeholder and is in either named div.</p> <p>I could of course just add in the <code>ontouchstart</code> attribute to each tr manually, but then I wouldn't learn anything new, and I'm thinking this can be done with less code with jQuery.</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.
