can't update div

Hello

We have a set of <div>'s and <span>'s chained inside like

<div id="x">

<span class="y"></span>
<span class="something"></span>

<div id="xx">...something..... there is a java onhandler function here draw();</div>
<div id="yy"></div>

Now the problem is the onhandler function is supposed to access document.getelementbyid("yy") but i got a java error stating not found element.

How can i make this access there?

 

Not Java, but JavaScript. And not getelementbyid but getElementById. Maybe your problem is in this syntax error.... If not, post more code (java script also).

 

HTML

<span class="label">Back Links:</span><input type="radio" name="linktype" id="linktype" value="2" onClick="toggler('backlinks')"  /><br /><br />
<div id="backlinks" style="display: none;"><span class="label">How Many Backlinks</span><select name="bl" onChange="drawforms()"><option value="0">0</option><option value="1">1</option><option value="2">2</option><option value="3">3</option><option value="4">4</option><option value="5">5</option><option value="6">6</option><option value="7">7</option><option value="8">8</option><option value="9">9</option><option value="10">10</option></div><br /><br />
<div id="backforms"></div>

Code (markup):

JS here.
I did not include all operations, they are not needed. I have tried different combinations and the error is in the div updating part below.

function drawforms() {

// some operations here
document.getElementById("backforms").innerHTML = str;

}

Code (markup):

 

You are missing closing </select> tag.
From your code it seems that depending on dropdown selection you want to display different content in <div id="backforms">? Here is a function that check which value was selected and then update a div (now it's working only with number 0 as an example):

function drawforms() {
	var loc = document.getElementById("backforms");
	var x = document.getElementById("b1"); 
	var y = x.options[x.selectedIndex].text;
	if(y == 0) { loc.innerHTML = 'Here I am!';}
	}

Code (markup):

You have to add to <select> an id="b1". Also add as a _first option_ an empty string or something like "Make selection". Why? You're using onchange and when page loads number 0 will be already selected. So when you try to select 0 nothing will happen.
