Call Javascript function from html

**justin.golden** · 02-05-2013 09:32 PM

I'm trying to call a javascript function and its not working. I click, but nothing appears to happen. Any help is appreciated

Code:

<body>

<script>
var brushVar;


function blue() {
    brushVar = ("#000000");
    alert(brushVar);
}

function blueN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function cyan() {
    brushVar = ("#000000");
    alert(brushVar);
}

function cyanN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function green() {
    brushVar = ("#000000");
    alert(brushVar);
}

function greenN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function purple() {
    brushVar = ("#000000");
    alert(brushVar);
}

function purpleN() {
    brushVar = ("#000000");
    alert(brushVar);
}

function red() {
    brushVar = ("000000");
    alert(brushVar);
}

function redN() {
    brushVar = ("000000");
    alert(brushVar);
}

function yellow() {
    brushVar = ("#000000");
    alert(brushVar);
}

function yellowN() {
    brushVar = ("#000000");
    alert(brushVar);
}
</script>





<div id="buttons" style="position:absolute; width:100%; height:100%>
 <a href="#" onclick="blue()';" >
    <img src="/blue.png"/>
</a>
<a href="#" onclick="blueN()';" >
    <img src="blueN.png"/>
</a>
<a href="#" onclick="cyan()';" >
    <img src="cyan.png"/>
</a>
<a href="#" onclick="cyanN()';" >
    <img src="cyanN.png"/>
</a>
<a href="#" onclick="green()';" >
    <img src="green.png"/>
</a><a href="#" onclick="greenN()';" >
    <img src="greenN.png"/>
</a>
<a href="#" onclick="purple()';" >
    <img src="purple.png"/>
</a>
<a href="#" onclick="purpleN()';" >
    <img src="purpleN.png"/>
</a>
<a href="#" onclick="red()';" >
    <img src="red.png"/>
</a>
<a href="#" onclick="redN()';" >
    <img src="redN.png"/>
</a>
<a href="#" onclick="yellow()';" >
    <img src="yellow.png"/>
</a>
<a href="#" onclick="yellowN()';" >
    <img src="yellowN.png"/>
</a>
</div>
</body>

Hi,
your onclick is in the wrong spot and you don't need to include the semicolon:

HTML Code:

<a href="#">
    <img src="/blue.png" onclick="blue()"/>
</a>
<a href="#" >
    <img src="blueN.png" onclick="blueN()"/>
</a>

Without seeing your images, I'm not sure if this is what it is supposed to do, but here's a shorter attempt...

Code:

<htm>
<head>
<title> Undefined </title>

<script type="text/javascript">
var brushVar;
function colours(cInfo) { brushVar = cInfo; alert(brushVar); return false; }
</script>
</head>

<body>
<div id="buttons" style="position:absolute; width:100%; height:100%">
  <a href="#" onclick="return colours('#0000ff')"> <img src="./blue.png" title="blue" /> </a>
  <a href="#" onclick="return colours('transparent')"> <img src="./blueN.png" title="transparent" /> </a>

  <a href="#" onclick="return colours('cyan')"> <img src="./cyan.png" title="cyan" /> </a>
  <a href="#" onclick="return colours('transparent')"> <img src="./cyanN.png" title="transparent" /> </a>

  <a href="#" onclick="return colours('#00ff00')"> <img src="./green.png" title="green" /> </a>
  <a href="#" onclick="return colours('transparent')"> <img src="./greenN.png" title="transparent" /> </a>

  <a href="#" onclick="return colours('purple')"> <img src="./purple.png" title="purple" /> </a>
  <a href="#" onclick="return colours('transparent')"> <img src="./purpleN.png" title="transparent" /> </a>

  <a href="#" onclick="return colours('#ff0000')"> <img src="./red.png" title="red" /> </a>
  <a href="#" onclick="return colours('transparent')"> <img src="./redN.png" title="transparent" /> </a>

  <a href="#" onclick="return colours('yellow')"> <img src="./yellow.png" title="yellow" /> </a>
  <a href="#" onclick="return colours('transparent')"> <img src="./yellowN.png" title="transparent" /> </a>
</div>
</body>
</html>

Replace with your images (change path if necessary)

Or explain further what it is that you are trying to do...
