Question

我想在 SVG rect中显示一些文本。有可能吗？

我试过

<svg xmlns="http://www.w3.org/2000/svg"> <g> <rect x="0" y="0" width="100" height="100" fill="red"> <text x="0" y="10" font-family="Verdana" font-size="55" fill="blue"> Hello </text> </rect> </g> </svg>

但它不起作用。

Answer 1

这是不可能的。如果要在rect元素中显示文本，则应将它们放在一个组中，文本元素位于rect元素之后（因此它显示在最上面）。

<svg xmlns="http://www.w3.org/2000/svg">
  <g>
    <rect x="0" y="0" width="100" height="100" fill="red"></rect>
    <text x="0" y="50" font-family="Verdana" font-size="35" fill="blue">Hello</text>
  </g>
</svg>

Answer 2

以编程方式使用D3：

body = d3.select('body')
svg = body.append('svg').attr('height', 600).attr('width', 200)
rect = svg.append('rect').transition().duration(500).attr('width', 150)
                .attr('height', 100)
                .attr('x', 40)
                .attr('y', 100)
                .style('fill', 'white')
                .attr('stroke', 'black')
text = svg.append('text').text('This is some information about whatever')
                .attr('x', 50)
                .attr('y', 150)
                .attr('fill', 'black')

<svg xmlns="http://www.w3.org/2000/svg" version="1.1">
    <g>
  <defs>
    <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(145,200,103);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(132,168,86);stop-opacity:1" />
    </linearGradient>
  </defs>
  <rect width="220" height="30" class="GradientBorder" fill="url(#grad1)" />
  <text x="60" y="20" font-family="Calibri" font-size="20" fill="white" >My Code , Your Achivement....... </text>
  </g>
</svg>

您可以使用 foreignobject 进行更多控制，并将丰富的HTML内容放置在矩形或圆形上

    <svg width="250" height="250" xmlns="http://www.w3.org/2000/svg">
        <rect x="0" y="0" width="250" height="250" fill="aquamarine" />
        <foreignobject x="0" y="0" width="250" height="250">
            <body xmlns="http://www.w3.org/1999/xhtml">
                <div>Here is a long text that runs more than one line and works as a paragraph</div>
                <br />
                <div>This is <u>UNDER LINE</u> one</div>
                <br />
                <div>This is <b>BOLD</b> one</div>
                <br />
                <div>This is <i>Italic</i> one</div>
            </body>
        </foreignobject>
    </svg>

使用基本Javascript以编程方式在rect上显示文本

 var svg = document.getElementsByTagNameNS('http://www.w3.org/2000/svg', 'svg')[0];

        var text = document.createElementNS('http://www.w3.org/2000/svg', 'text');
        text.setAttribute('x', 20);
        text.setAttribute('y', 50);
        text.setAttribute('width', 500);
        text.style.fill = 'red';
        text.style.fontFamily = 'Verdana';
        text.style.fontSize = '35';
        text.innerHTML = "Some text line";

        svg.appendChild(text);

        var text2 = document.createElementNS('http://www.w3.org/2000/svg', 'text');
        text2.setAttribute('x', 20);
        text2.setAttribute('y', 100);
        text2.setAttribute('width', 500);
        text2.style.fill = 'green';
        text2.style.fontFamily = 'Calibri';
        text2.style.fontSize = '35';
        text2.style.fontStyle = 'italic';
        text2.innerHTML = "Some italic line";

       
        svg.appendChild(text2);

        var text3 = document.createElementNS('http://www.w3.org/2000/svg', 'text');
        text3.setAttribute('x', 20);
        text3.setAttribute('y', 150);
        text3.setAttribute('width', 500);
        text3.style.fill = 'green';
        text3.style.fontFamily = 'Calibri';
        text3.style.fontSize = '35';
        text3.style.fontWeight = 700;
        text3.innerHTML = "Some bold line";

       
        svg.appendChild(text3);

    <svg width="510" height="250" xmlns="http://www.w3.org/2000/svg">
        <rect x="0" y="0" width="510" height="250" fill="aquamarine" />
    </svg>
