    <p>I am showing <code>alerts if 3 textboxes or any single text box is empty</code>. For example: if <code>all are empty then alert will be" please fill up all"</code> <code>else if 1st and 2nd text boxes are empty then alert will be "please fill up 1st and 2nd text box"</code> similarly <code>if 1st and 3rd text boxes are empty then alert will be "please fill up 1st and 3rd text box"</code> similarly <code>if 2nd and 3rd text boxes are empty then alert will be "please fill up 2nd and 3rd text box"</code> similarly <code>if only 1st text box is empty then alert will be "please fill up 1st text box"</code> similarly <code>if only 2nd text box is empty then alert will be "please fill up 2nd text box"</code> similarly <code>if only 3rd text box is empty then alert will be "please fill up 3rd text box"</code></p> <p>But problem is i have to write so many <code>if-else statements</code> in javascript if <code>number of text boxes are 10 or more</code>. Is their any solution for this to minimize the <code>code</code> and <code>accordingly alert will come if any of the above condition satisfies</code>?</p> <p>I have written the <code>if-else code</code> individually but it is very lengthy like this:</p> <pre><code> &lt;form name="frm" action="confirmsubmit.jsp"&gt; &lt;script type="text/javascript"&gt; &lt;!-- function confirmation() { var textboxname1=document.frm.textboxname1; var textboxname2=document.frm.textboxname2; var textboxname3=document.frm.textboxname3; //alert if all text boxes are empty if((textboxname1.value==null)||(textboxname1.value=="")&amp;&amp; (textboxname2.value=="")||(textboxname2.value==null)){ alert("Please fill up first text box&lt;br/&gt;Please fill up second text box&lt;br/&gt;Please fill up 3rd text box");//alert for all textboxname1.focus(); return false } //alert if 2nd text box is empty else if((textboxname2.value=="")||(textboxname2.value==null)) { alert("Please Please fill up second text box");//alert for 2nd text box textboxname2.focus(); return false } //alert if 3rd text box is empty else if((textboxname3.value=="")||(textboxname3.value==null)) { alert("Please Please fill up third text box");//alert for 3rd text box textboxname3.focus(); return false } // similarly i have to show alert if 2nd and 3rd boxes are empty and so on, but is there any solution to minimize the code? return true } //--&gt; &lt;/script&gt; &lt;input type="text" name="textboxname1"/&gt; &lt;input type="text" name="textboxname2"/&gt; &lt;input type="text" name="textboxname3"/&gt; &lt;input type="submit" onclick="return confirmation()"/&gt; &lt;/form&gt; </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.
