如何确定 SVG 文本框宽度或在"x"个字符后强制换行?

使用 getBBox() 函数并一次向文本对象添加一个单词。当文本太宽时，您需要添加换行符。
var a = Raphael(500, 500);
var b = a.text(100, 100).attr('text-anchor', 'start');
var maxWidth = 100;
var content = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis nec semper mauris. Sed gravida augue feugiat nulla ultrices efficitur. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. Sed sit amet lobortis eros, et lobortis diam. Aenean arcu velit, condimentum eu lacus in, dignissim bibendum odio. Mauris ultricies nunc et lorem bibendum dignissim. Ut porttitor purus vitae diam efficitur ultrices. Integer dignissim efficitur lorem, non vehicula diam scelerisque at ";
var w = content.split(" ");
var tempText = "";
for (var i = 0; i < w.length; i++) {
b.attr("text", tempText + " " + words[i]);
if (b.getBBox().width > maxWidth) {
tempText += "
" + words[i];
} else {
tempText += " " + words[i];
}
}
b.attr("text", tempText.substring(1));
