    <p>I'm learning Javascript for a project. I'm trying to try and get values from an dynamic number of text inputs into a multi-dimensional array. I have tried this with 1 text field and it correctly saves into the array for further manipulation later. However when i added an second text field and another dimension to the array, it broke. Eventually i will have a drop down list to give the number of inputs once i figure it out. Here's my current code, not very efficient really. </p> <pre><code> &lt;html&gt; &lt;head&gt; &lt;title&gt; JavaScript Array from Input&lt;/title&gt; &lt;script&gt; var array = new Array(); function insert(val){ array[0][array.length]=val; } function insert2(val){ array[array.length][0]=val; } function show() { var string="&lt;b&gt;All Element of the Array :&lt;/b&gt;&lt;br&gt;"; for(i = 0; i &lt; array.length; i++) { string =string+array[i][0]+"&lt;br&gt;"; string =string+array[0][i]+"&lt;br&gt;"; } if(array.length &gt; 0) document.getElementById('myDiv').innerHTML = string; } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;h2&gt;JavaScript Array from Input&lt;/h2&gt; &lt;form name="form1"&gt; &lt;table width="407"&gt; &lt;tr&gt; &lt;td width="154" align="right"&gt;&lt;b&gt;Name&lt;/b&gt; &lt;td width="9"&gt;&lt;b&gt;&amp;nbsp;:&lt;/b&gt; &lt;td width="224"&gt; &lt;input type="integer" name="name"/&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td width="154" align="right"&gt; &lt;td width="9"&gt; &lt;td width="224"&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td width="154" align="right"&gt; &lt;td width="9"&gt; &lt;td width="224"&gt; &lt;td width="154" align="right"&gt;&lt;b&gt;Name2&lt;/b&gt; &lt;td width="9"&gt;&lt;b&gt;&amp;nbsp;:&lt;/b&gt; &lt;td width="224"&gt; &lt;input type="integer" name="name2"/&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td width="154" align="right"&gt; &lt;td width="9"&gt; &lt;td width="224"&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td width="154" align="right"&gt; &lt;td width="9"&gt; &lt;td width="224"&gt; &lt;input type="button" Value="Add Into Array" onclick="insert(this.form.name.value), insert2(this.form.name2.value);"/&gt; &lt;input type="button" Value="alert" onclick="alert(array[0][0])"/&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/form&gt; &lt;div id="myDiv"&gt;&lt;/div&gt; &lt;/body&gt; </code></pre> <p></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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
