    <p>Please change your validation and form to this which will allow submission of the form if valid and not if errors. The following code is in my opinion <em>canonical</em> and will work on all browsers that support regular expressions (which was introduced in JS1.1 in 1996 with NS3.0) - please note that javascript does not support dashes in names unless you quote the field name in the script. The code does not need the form to be named since it passes the form object in the call <em>(this)</em> and uses the object in the function as <em>theForm</em></p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Canonical forms validation without jQuery&lt;/title&gt; &lt;script type="text/javascript"&gt; var validName = /^[A-Za-z]+$/; function checkName(str) { return validName.test(str); } function verify(theForm) { // note: theForm["..."] is short for theForm.elements["..."]; var amount = theForm["exp_amount"].value; if(amount ==""){ alert("Block Amount is left blank"); theForm["exp_amount"].focus(); return false; } if (isNaN(amount)) { alert("Invalid Block Amount"); theForm["exp_amount"].focus(); return false; } var name = theForm["exp_name"].value; if(name.length==0) { alert("Block Exp is left Blank!"); theForm["exp_name"].focus(); return false; } if(!checkName(name)) { alert("Block Exp is invalid!"); theForm["exp_name"].focus(); return false; } return true; } &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;form onsubmit="return verify(this)"&gt; Amount: &lt;input type="text" name="exp_amount" value="" /&gt;&lt;br /&gt; Name: &lt;input type="text" name="exp_name" value="" /&gt;&lt;br /&gt; &lt;input type="submit" /&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre>

    2. CO@Dinzy - sure. If you have dashes in the names, then the code changes. Please edit the text of your question to reflect the actual situation in such cases. I will update my code. My code does not need the name of the form since we pass the form object in the verify function

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.

SQuiL has stopped working due to an internal error.

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