    <p>I have written the following code in html and the javascript file is also embedded below</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;meta charset="utf-8"&gt; &lt;HTML&gt; &lt;head&gt; &lt;link rel="stylesheet" href="admin.css"/&gt; &lt;script type="text/javascript" src="common.js"&gt;&lt;/script&gt; &lt;/head&gt; &lt;BODY&gt; &lt;div class="adminnav" id="adminnav"&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="#"&gt;Insert&lt;/a&gt; &lt;ul&gt; &lt;li&gt;&lt;a href="addcourse.html"&gt;Insert Course&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="addstudent.html"&gt;Insert Student&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="addteacher.html"&gt;Insert Teacher&lt;/a&gt;&lt;/li&gt; &lt;li&gt;&lt;a href="addsubject.html"&gt;Insert Subject&lt;/a&gt;&lt;/li&gt; &lt;/ul&gt; &lt;/li&gt; &lt;/ul&gt; &lt;/div&gt; &lt;div class="addcourse" &gt; &lt;form name="course" onSubmit='return validcourse()' method="POST"&gt; Course Name: &lt;input type="text" name="coursename" id="cname" /&gt;&lt;br&gt; Duration:&lt;input type="text" name="cd"/&gt; &lt;br&gt; Course Id:&lt;input name="cid" type="text" /&gt;&lt;br&gt; &lt;input type="submit" value="submit" name="submit"&gt;&lt;input type="reset" name="coursereset"&gt; &lt;/form&gt; &lt;/div&gt; &lt;/BODY&gt; &lt;/HTML&gt; </code></pre> <p>common.js</p> <pre><code>function validcourse() { var course_name=document.course.coursename; var course_duration=document.course.cd; var course_id=document.course.cid; if(course_name_valid(course_name)) { { if(course_duration_valid(course_duration)) { if(course_id_valid(cid)) { } } } } } function course_name_valid(course_name) { var letters=/^[A-Za-z]+$/; if(course_name.value.match(letters)) { return true; } else { alert("Course name must have alphabets only"); course_name.focus(); return false; } } function course_duration_valid(course_duration) { var letters=/^[1-9]+$/; if(cd.value.match(letters)) { return true; } else { alert("Course Duration can have numbers only"); course_duration.focus(); retun false; } } function course_id_valid(course_id) { var letters=/^[0-9a-zA-z]+$/; if(course_id.value.match(letters)) { return true; } else { alert('Course ID must have character and numeric values only'); course_id.focus(); return false; } } </code></pre> <p>My problem is that nothing is happening no error messages are given. Error messages are given only for course name but not for course duration and course id?</p> <p>Here is a link to jsfiddle <a href="http://jsfiddle.net/amolkarale/aTfq6/1/" rel="nofollow">http://jsfiddle.net/amolkarale/aTfq6/1/</a></p>

    1. COPut an alert at the top of your js and see if that executes. I suspect you are calling the wrong file.

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).
