Modify a svg file using jQuery

I have a svg file with some shape and some text. I'd like to modify the svg at runtime, so that some shape can change color, and some text can change its content.

Let's suppose that I have only two elements in an external svg file:

  1. circle1: a blue filled circle witdh that id

  2. text1: a text containing "--" with that id

Now I can view the file in my html with

<object data="Sample.svg" type="image/svg+xml" width="200" height="200" id="svg1"></object>

From a button near the image, using jQuery, I can catch the onClick event: I'd like to fill the cicle with red and change the text to "hello word".

How can I do that? Is there a jQuery based solution?

I have found the jquery.svg plugin, but it seem that you can only modify a runtime created document.

Thanks.

Done!

Finally I found documentation on jQuery.svg. and on svg itself.

Let's start with the code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title></title>

<script type="text/javascript" src="../js/jquery-1.5.min.js"></script>
<script type="text/javascript" src="jquery.svg/jquery.svg.js"></script> 
</head>
<body>

<script type="text/javascript">

$(document).ready(function() 
    {
    $("#svgload").svg({
        onLoad: function()
            {
            var svg = $("#svgload").svg('get');
            svg.load('Red1.svg', {addTo: true,  changeSize: false});        
            },
        settings: {}}
        );  


    $('#btnTest').click(function(e)
        {
        var rect = $('#idRect1');
        rect.css('fill','green');
        //rect.attrib('fill','green');

        var txt = $('#idText1');
        txt.text('FF');
     });    

    });
</Script>   

<div id="svgload" style="width: 100%; height: 300px;"></div>

<div id="btnTest">
Click Me!
</div>

</body>
</html>

And this sample Red1.svg file:

<svg xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink">

<rect id="idRect1" fill="#FF0000" width="300" height="300"/> 
<text id="idText1" x="20" y="20" font-family="sans-serif" font-size="20px" fill="black">Hello!</text>

</svg>

Using jQuery, I loaded the external Red1.svg at runtime. With a click on btnTest I set the text and the fill color.

In my research I have found that:

  1. With jQuery.svg I can access the elements in the SVG file and standard html tag
  2. SVG lets you choose the way you want to set the fill color

    2a. with a style

        rect.css('fill','green');
    

    2b. with a specific tag

        rect.attr('fill','green');
    

So your code must change depending on the program that generated the svg.

Have a nice day.
