I want to create a rectangle inside an HTML page, then write some text on that rectangle. I also need that text to be a hyperlink. This is what I did but it is not working:
<!DOCTYPE html>
<html>
<body>
<script>
var svg = document.documentElement;
var svgNS = svg.namespaceURI;
var rect = document.createElementNS(svgNS,'rect');
rect.setAttribute('x',5);
rect.setAttribute('y',5);
rect.setAttribute('width',500);
rect.setAttribute('height',500);
rect.setAttribute('fill','#95B3D7');
svg.appendChild(rect);
document.body.appendChild(svg);
var h=document.createElement('a');
var t=document.createTextNode('Hello World');
h.appendChild(t);
document.body.appendChild(h);
</script>
</body>
</html>
Can you help please? Thanks.
This question is related to
javascript
html
svg
Add this to html:
<svg id="mySVG" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"/>
Try this function and adapt for you program:
var svgNS = "http://www.w3.org/2000/svg";
function createCircle()
{
var myCircle = document.createElementNS(svgNS,"circle"); //to create a circle. for rectangle use "rectangle"
myCircle.setAttributeNS(null,"id","mycircle");
myCircle.setAttributeNS(null,"cx",100);
myCircle.setAttributeNS(null,"cy",100);
myCircle.setAttributeNS(null,"r",50);
myCircle.setAttributeNS(null,"fill","black");
myCircle.setAttributeNS(null,"stroke","none");
document.getElementById("mySVG").appendChild(myCircle);
}
To facilitate svg editing you can use an intermediate function:
function getNode(n, v) {
n = document.createElementNS("http://www.w3.org/2000/svg", n);
for (var p in v)
n.setAttributeNS(null, p, v[p]);
return n
}
Now you can write:
svg.appendChild( getNode('rect', { width:200, height:20, fill:'#ff0000' }) );
Example (with an improved getNode function allowing camelcase for property with dash, eg strokeWidth > stroke-width):
function getNode(n, v) {_x000D_
n = document.createElementNS("http://www.w3.org/2000/svg", n);_x000D_
for (var p in v)_x000D_
n.setAttributeNS(null, p.replace(/[A-Z]/g, function(m, p, o, s) { return "-" + m.toLowerCase(); }), v[p]);_x000D_
return n_x000D_
}_x000D_
_x000D_
var svg = getNode("svg");_x000D_
document.body.appendChild(svg);_x000D_
_x000D_
var r = getNode('rect', { x: 10, y: 10, width: 100, height: 20, fill:'#ff00ff' });_x000D_
svg.appendChild(r);_x000D_
_x000D_
var r = getNode('rect', { x: 20, y: 40, width: 100, height: 40, rx: 8, ry: 8, fill: 'pink', stroke:'purple', strokeWidth:7 });_x000D_
svg.appendChild(r);
_x000D_
Change
var svg = document.documentElement;
to
var svg = document.createElementNS("http://www.w3.org/2000/svg", "svg");
so that you create a SVG
element.
For the link to be an hyperlink, simply add a href
attribute :
h.setAttributeNS(null, 'href', 'http://www.google.com');
