    <p>I have a javascript function written to validate a field on my form. This function is supposed to make sure the field is not empty, does not exceed the limit of 35 characters and only contains alphabetic characters and a hyphen(-). I had code to make sure the field is not empty and that it does not exceed 35 characters which worked fine but i added code to validate the field to the usable characters and i tested it out by leaving the field empty to make sure that still worked but when i hit the submit button the function didn't seem to validate at all, didn't give me an alert and just submitted. Here is my code: </p> <pre><code>function validateFamily() { var family=document.getElementById('family'); var stringf = document.getElementById('family').value; if (family.value=="") { alert("Family name must be filled out"); return false; } else if (document.getElementById('family').value.length &gt; 35) { alert("Family name cannot be more than 35 characters"); return false; } else if (/[^a-zA-Z\-\]/.test( stringf )) { alert("Family name can only contain alphanumeric characters and hypehns(-)") return false; } return true; } &lt;form name="eoiform" method="POST" action="&lt;?php echo $_SERVER["PHP_SELF"];?&gt;" id="eoi" onsubmit="return validateFamily() &amp;&amp; validateGiven() &amp;&amp; validateMaleFemale() &amp;&amp; validDate() &amp;&amp; validateAddress() &amp;&amp; validatePost() &amp;&amp; validateParent() &amp;&amp; validateWork() &amp;&amp; validateHome() &amp;&amp; validateMob() &amp;&amp; validateCheckBoxes();"&gt; &lt;b&gt;Student's Family Name&lt;/b&gt; &lt;br&gt; &lt;input type="text" id="family" name="family" /&gt;&lt;?php echo $strmsgf; ?&gt; &lt;input type="submit" name="submit" id="submit" value="submit" /&gt; &lt;/form&gt; </code></pre> <p>Could anyone show me how to fix my code?</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).
