Question

我正在执行翻译功能，我想轻松地在对象内添加翻译，然后在$("body").html()内全局更改每个翻译，问题是，当我在for循环内使用new RegExp()时，在第一次迭代后剪切循环。

if (window.location.href.indexOf("sv") > -1) {
    //CUSTOM TRANSLATIONS

    var translations = {
        'All': 'alla',
        'Filter Members': 'Filtrera medlemar',
    }



    for (var key in translations) {
        if (translations.hasOwnProperty(key)) {

            console.log(key + " -> " + translations[key]);
            $body = jQuery("body");
            replaceThis = new RegExp(key, "g");

            alert(replaceThis);

            $body.html($body.html().replace(replaceThis, translations[key]));

        }
    }

}

Answer 1

似乎您的body标签内包含脚本，因此您的脚本遇到错误。尝试在所有html上添加一个html容器元素，然后对该容器元素而不是主体执行操作。

var translations = {
  'All': 'alla',
  'Filter Members': 'Filtrera medlemar'
};

for (var key in translations) {
  if (translations.hasOwnProperty(key)) {

    //console.log(key + " -> " + translations[key]);
    $container = jQuery(".container");
    replaceThis = new RegExp(key, "g");

    //alert(replaceThis);

    $container.html($container.html().replace(replaceThis, translations[key]));

  }
}

<div class="container">
  <div>All</div>
  <div>Filter Members</div>
  <div>All</div>
  <div>Filter Members</div>
</div>

Answer 2

在使用二维数组时，您需要将2个参数绑定到函数上，一个参数用于键，一个参数用于值。这个例子应该可以。

val baseConverted = ["-2","50","48"]

问题

请勿定位<html>或<body>标签，窗口或文档-定位嵌套在<body>中的元素作为Aggarwal先生的answer和iArcadia的元素评论建议。
iArcadia的评论还指出，这里有多余的代码：translations.hasOwnProperty(key)
正如Stribiżew先生在评论中指出的那样，应该对通过RegExp对象传递的搜索字符串进行转义。在不转义给定字符串的情况下，会出现不想要的结果，例如：
- 匹配的子字符串（例如，搜索字符串：所有匹配： 所有 igator）
  < / li>
- 匹配的HTML标签（例如搜索字符串： class 匹配项： <div class ="...> ）

解决方案

我刚刚编写了一个名为 .translateWord（）的快速jQuery插件：

用法：$(selector).translateWord(matrix)
Param：
selector {string}：CSS / jQuery选择器字符串语法
matrix {array}：键/值对的二维数组

它将给定的数组数组（ matrix ）转换为ES6地图（ dictionary ）。每个键（ keyword ）被转义（ escape ）：

`(?!(?:[^<]+>|[^>]+<\\/a>))\\b(${keyword})\\b`

然后通过RegExp（）对象（ regex ）传递，该对象依次搜索并替换为与 dictionary 键对应的 dictionary 值

let en2sv = [
  ['them', 'dem'],
  ['you', 'du'],
  ["I'm", 'Jag är'],
  ['was', 'var']
];

(function($) {
  $.fn.translateWord = function(matrix) {
    let dictionary = new Map(matrix);
    for (let keyword of dictionary.keys()) {
      let string = $(this).html();
      let escape = `(?!(?:[^<]+>|[^>]+<\\/a>))\\b(${keyword})\\b`;
      let regex = new RegExp(escape, "gi");
      let html = string.replace(regex, `<mark>${dictionary.get(keyword)}</mark>`);
      $(this).html(html);
    }
  }
})(jQuery);

$('main').translateWord(en2sv);
