svg - 在行中添加文字(Add text to line)

Question

I used svg.draw.js to allow the user to create a sketch of a terrace.

(我使用svg.draw.js允许用户创建露台的草图。)

I'd like to add a label above each line to show the length of the line.

(我想在每行上方添加一个标签，以显示行的长度。)

I've tried several things but none of them were good enough.

(我已经尝试了好几件事，但是没有一件事情足够好。)

Please have a look at this fiddle: https://jsfiddle.net/mdemuynck/pxy4f9o0/8/#&togetherjs=8oMIQFQmBg/

(请看一下这个小提琴： https : //jsfiddle.net/mdemuynck/pxy4f9o0/8/#&togetherjs=8oMIQFQmBg/)

var poly2 = new SVG('polygonGrid').size('100%', '300')
    .polygon().draw({snapToGrid:20});

poly2.on('drawstart', function(e){
    document.addEventListener('keydown', function(e){
        if(e.keyCode == 13){
            poly2.draw('done');
            poly2.off('drawstart');
        }
    });
});

poly2.on('drawstop', function(){
    // remove listener
});
