DOM对应的SVG元素

Question

我想在SVG下使用DOM创建标签，我需要一些帮助。我无法弄清楚如何设置“rect”标签的属性。以下是HTML代码的快照。我想创建使用DOM的相同。

<svg xmlns="http://www.w3.org/2000/svg" id="svg" width ="1500" height="1500"> 
     <text x="0" y="15" fill="black">AISLE A</text> 

     <rect x=10 y=45 rx="10" ry="10" width="40" height="40" style="fill:red;stroke:black;opacity:0.5" onmouseover="this.style.stroke = 'black'; this.style['stroke-width'] = 5;" onmouseout="this.style.stroke = '#000000'; this.style['stroke-width'] = 1;"> 
      <title id="title1"> 
      Location: FP-A-02</br>Replenrate: xx%</br>PickRate: yy% 
      </title> 
      </rect> 

      <rect x=60 y=45 rx="10" ry="10" width="40" height="40" style="fill:red;stroke:black;opacity:0.5" onmouseover="this.style.stroke = 'black'; this.style['stroke-width'] = 5;" onmouseout="this.style.stroke = '#000000'; this.style['stroke-width'] = 1;"> 
      <title id="title2"> 
      Location: FP-A-02</br>Replenrate: xx%</br>PickRate: yy% 
      </title> 
      </rect> 
    <text x="0" y="15" fill="black">AISLE B</text>  
      <rect x=110 y=45 rx="10" ry="10" width="40" height="40" style="fill:red;stroke:black;opacity:0.5" onmouseover="this.style.stroke = 'black'; this.style['stroke-width'] = 5;" onmouseout="this.style.stroke = '#000000'; this.style['stroke-width'] = 1;"> 
      <title id="title3"> 
      Location: FP-A-02</br>Replenrate: xx%</br>PickRate: yy% 
      </title> 
      </rect> 

      <rect x=160 y=45 rx="10" ry="10" width="40" height="40" style="fill:red;stroke:black;opacity:0.5" onmouseover="this.style.stroke = 'black'; this.style['stroke-width'] = 5;" onmouseout="this.style.stroke = '#000000'; this.style['stroke-width'] = 1;"> 
      <title id="title4"> 
      Location: FP-A-02</br>Replenrate: xx%</br>PickRate: yy% 
      </title> 
      </rect> 
<svg> 

请注意，有2 AISLES A和B.我会创建每个AISLES内20米的矩形。手动创建它们不是一种优化的方式，因此希望使用DOM来创建元素。

您可以像处理其他DOM元素一样处理svg标签。例如：

// Create the SVG from scratch or get one already on your DOM 
// For sake of example, here we create one. 
var svg = document.createElementNS("http://www.w3.org/2000/svg", "svg"); 
// Same logic for the inner tags 
var rect = document.createElementNS(svg.namespaceURI, 'rect'); 

// Once you have reference to the element, setting attributes is simple. 
// https://developer.mozilla.org/en/docs/Web/API/Element/setAttribute 
rect.setAttribute('x', 0); 
// ... 

// At the end you append all your child elements to the parent 
svg.appendChild(rect); 
// ...
