Making textboxes appear on a webpage using javascript

Q_Ball

hey guys just a quickie,

I want textboxes to appear only when the user clicks a checkbox. The code i have doesnt work (it never does )

javascript

function searchAuthor() {

	var checkbox = window.document.form2.check_1;

	if (checkbox == false) {
		window.document.writeln("<tr><td>Please enter the author of the book you wish to search for:</td>")
		window.document.writeln("<td><INPUT TYPE=text ID=author NAME=author></td></tr>")
		}

	}

the form

<FORM NAME=form METHOD=get ACTION="./myass.htm" onSubmit="return check()">
<TABLE>
<tr>
	<td>
		Please enter the title of the book you wish to search for:
	</td>
	<td>
		<INPUT TYPE=text ID=title NAME=title>
	</td>
</tr>
<tr><td>
<input type="checkbox" name ="check_1" onClick="searchAuthor();">Search by Author
</td></tr>
<tr>
	<td>
		&nbsp
	</td>
	<td>
		<INPUT id=reset type=reset value=Reset name=reset>
		<INPUT id=submit type=submit value=Submit name=submit>
	</td>
</tr>
</TABLE>
</FORM>

Any ideas?

Try this:

(Haven't tested it)


HTML:

<FORM NAME=form METHOD=get ACTION="./myass.htm" onSubmit="return check()">
<TABLE>
<tr>
	<td>
		Please enter the title of the book you wish to search for:
	</td>
	<td>
		<INPUT TYPE=text ID=title NAME=title>
	</td>
</tr>
<tr><td>
<input type="checkbox" id="check_1" name ="check_1" onClick="searchAuthor();">Search by Author
</td></tr>
<tr>
	<td>
		<div id="textboxen" style="display: none">
                    Please enter the author of the book you wish to search for:
		    <INPUT TYPE=text ID=author NAME=author>
               </div>
	</td>
	<td>
		<INPUT id=reset type=reset value=Reset name=reset>
		<INPUT id=submit type=submit value=Submit name=submit>
	</td>
</tr>
</TABLE>
</FORM>

Javascript:

function searchAuthor() {
   if(document.getElementById){
	var textboxes = document.getElementById("textboxen");
        var chkbx = document.getElementById("check_1");
       
         if(chkbx.checked = true)
             textboxes.style.display = "block";
         else
             textboxes.style.display = "none;
	
   }
}
