Question

我正在使用p5.js中的RiTa库从一首诗中制作一个“疯狂的lib”。为了正确输出字符，我使用了rita.tokenize函数使每个单词/字符成为数组中的值。然后我使用textWidth（）来正确输出字符，在每个数组值周围添加“”，这样这些单词就不会变成这样。但是，通过这样做，我还在逗号，句号，问号等周围添加了额外的空格，看起来很奇怪。如何有选择地删除这些？我在JavaScript中查看它，但没有找到p5.js和RiTa的任何内容。有没有办法识别标点符号，然后使用布尔语句来纠正这个？或者我是否需要抛弃数组并使用字符串进行硬编码？感谢帮助！（请忽略我评论过的内容，我正在玩一些额外的文字）。克莱尔

Answer 1

您可以使用简单的if语句连接它们时删除空格。像这样：

var wordOne = "one";
var wordTwo = ", three";

var combined;
if(wordTwo.startsWidth(",")){
   combined = wordOne + wordTwo;
}
else{
   combined = wordOne + " " + wordTwo;
}

您也可以使用正则表达式和replace()函数在创建String后修复它：

var wordOne = "one";
var wordTwo = ", three";
combined = wordOne + " " + wordTwo;
combined = combined.replace(/ ,/g, ',');

Answer 2

RiTa.untokenize（）旨在处理这种情况。您只需将单词添加到数组中，然后使用RiTa.untokenize（）：

var words = ['one', ',', 'two', ',', 'three', '.'];

var result = RiTa.untokenize(words); 

console.log(result); // -> "one, two, three."
