    <p>I am using javascript to validate a web form for submission to a database, I have coded the form and the validation, but it does not seem to work.</p> <p>When the form is completed and it is valid it is meant to go to a success page in a separate HTML file, but if it is not valid, the text on the form turns red, a message box pops up and alerts the user that it is invalid. On Chrome and IE, it seems to display the error but go to the success page anyway. The Message Box does not come up either, i only see the text turning red before it goes to the success page.</p> <p>I wanted to know how to fix this. I have searched on the Internet but found no solution.</p> <p>I have a function called <code>validateForm()</code>, which is a series of if statements checking the if the fields are valid, and if they are not, a variable called 'result' is set to false, at the end, it sends the alert message and returns the variable 'result'.</p> <p>The code for my submit button is here:</p> <pre><code>&lt;input type="submit" name="submit" value="Submit" onclick="return validateForm();" /&gt; </code></pre> <p>The Success Page is set in the form code as an 'action'.</p> <p>Here is my Validate Form :</p> <pre><code>function validateForm(){ var result = true; var msg = ""; if(document.ExamEntry.name.value==""){ msg+="You must enter your Name \n"; document.ExamEntry.name.focus(); document.getElementById('name').style.color="red"; result = false; } if(document.ExamEntry.subject.value==""){ msg+="You must enter the Subject \n"; document.ExamEntry.subject.focus(); document.getElementById('subject').style.color="red"; result = false; } if(document.ExamEntry.examNumber.value=="") { msg+="You must enter the Examination Number \n"; document.ExamEntry.examNumber.focus; document.getElementById('examnumber').style.color="red"; result = false; } if(document.ExamEntry.examNumber.value.length!=4) { msg+="Your Examination Number must be 4 characters long \n"; document.ExamEntry.examNumber.focus; document.getElementById('examnumber').style.color="red"; result = false; } var lvlmsg=""; for(var i=0; i &lt; document.ExamEntry.level.length; i++) { if(document.ExamEntry.level[i].checked) { lvlmsg = document.ExamEntry.level[i].value; break; } } if(lvlmsg=="") { msg+="You Must Indicate Your Level"; result=false; document.getElementById('radioButtons').style.color="red"; } else { alert(lvlmsg); } if(msg==""){ return result; } else{ alert(msg); return result; } } </code></pre>

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.
