How to place text in the center of an svg path


For rendering SVG I'm using jQuery SVG plugin. And, now I want to add text to each path and polygon. On jsFiddle you can see generated markup by plugin.

For creating text I wrote the following code:

var svgg = $("#rsr").svg('get');
var texts = svgg.createText();
svgg.textpath($("#Layer_x0020_1"),id, texts.string('We go ').
   span('up', { dy: -30, fill: 'red' }).span(',', { dy: 30 }).
   string(' then we go down, then up again'));

In the code on jsFiddle you can see that the textpath tag exists, but it's not visible. How to add text to the center of each path?
Thanks.


Solution

  • To place text in a straight line on top of a shape, in the middle of the boundingbox see:

    http://jsfiddle.net/dYuAA/114/

    It just adds some javascript to place text.

    function addText(p)
    {
        var t = document.createElementNS("http://www.w3.org/2000/svg", "text");
        var b = p.getBBox();
        t.setAttribute("transform", "translate(" + (b.x + b.width/2) + " " + (b.y + b.height/2) + ")");
        t.textContent = "a";
        t.setAttribute("fill", "red");
        t.setAttribute("font-size", "14");
        p.parentNode.insertBefore(t, p.nextSibling);
    }
    
    var paths = document.querySelectorAll("path");
    for (var p in paths)
    {
        addText(paths[p])
    }
    

    The above only looks at path elements, but you could tweak the selector to include whatever you need.
