將字串與包含任何型別字符的單詞拆分為整個單詞

嘗試從文本中正確提取所有術語。看起來當術語在句子內并且術語包含()它時沒有拆分并且正則運算式找不到它。

我正在嘗試正確拆分包含(). 所以代替這個：

["What is API(Application Programming Interface) and how to use it?"]

我試圖得到這個：

["What is", "API(Application Programming Interface)", "and how to use it?"]

JSON術語已正確提取，我得到了這個：

["JSON", "is a Javascript Object Notation"] 所以這正是我想要的，但如果是 API，我沒有得到這個：

["What is", "API(Application Programming Interface)", "and how to use it?"]

我得到了這個，這不是我想要的：

["What is API(Application Programming Interface) and how to use it?"]

function getAllTextNodes(element) {
    let node;
    let nodes = [];
    let walk = document.createTreeWalker(element,NodeFilter.SHOW_TEXT,null,false);
    while (node = walk.nextNode()) nodes.push(node);
    return nodes;
  }

const allNodes = getAllTextNodes(document.getElementById("body"))

const terms = [
    {id: 1, definition: 'API stands for Application programming Interface', expression: 'API(Application Programming Interface)'},
    {id: 2, definition: 'JSON stands for JavaScript Object Notation.', expression: 'JSON'}
]

const termMap = new Map(
      [...terms].sort((a, b) => b.expression.length - a.expression.length)
                .map(term => [term.expression.toLowerCase(), term])
    );

const regex = RegExp("\\b("   Array.from(termMap.keys()).join("|")   ")\\b", "ig");

for (const node of allNodes) {
    const pieces = node.textContent.split(regex).filter(Boolean);
    console.log(pieces)
}

<div id="body">
    <p>API(Application Programming Interface)</p>
    <p>What is API(Application Programming Interface) and how to use it?</p>
    <p>JSON is a Javascript Object Notation</p>
</div>

uj5u.com熱心網友回復：

由于您的“單詞”可以由非單詞字符組成，因此您不能依賴單詞邊界。我建議切換到明確的 ( (?<!\w)/ (?!\w)) 或自適應動態詞邊界。

此外，在正則運算式中使用之前，您需要轉義您的條款。

請參見下面具有自適應字邊界的示例：

function getAllTextNodes(element) {
    let node;
    let nodes = [];
    let walk = document.createTreeWalker(element,NodeFilter.SHOW_TEXT,null,false);
    while (node = walk.nextNode()) nodes.push(node);
    return nodes;
  }

const allNodes = getAllTextNodes(document.getElementById("body"))

const terms = [
    {id: 1, definition: 'API stands for Application programming Interface', expression: 'API(Application Programming Interface)'},
    {id: 2, definition: 'JSON stands for JavaScript Object Notation.', expression: 'JSON'}
]

const termMap = new Map(
      [...terms].sort((a, b) => b.expression.length - a.expression.length)
                .map(term => [term.expression.toLowerCase(), term])
    );

const regex = RegExp("(?:(?!\\w)|\\b(?=\\w))("   Array.from(termMap.keys()).map(x => x.replace(/[-\/\\^$* ?.()|[\]{}]/g, '\\$&')).join("|")   ")(?:(?<=\\w)\\b|(?<!\\w))", "ig");

for (const node of allNodes) {
    const pieces = node.textContent.split(regex).filter(Boolean);
    console.log(pieces)
}

<div id="body">
    <p>API(Application Programming Interface)</p>
    <p>What is API(Application Programming Interface) and how to use it?</p>
    <p>JSON is a Javascript Object Notation</p>
</div>

正則運算式現在(?:(?!\w)|\b(?=\w))(api\(application programming interface\)|json)(?:(?<=\w)\b|(?<!\w))在哪里

• (?:(?!\w)|\b(?=\w))- 左手自適應單詞邊界（如果以下字符是非單詞字符，則不進行背景關系檢查）
• (api\(application programming interface\)|json)- 組 1 匹配您的條件之一（請參閱轉義特殊字符）
• (?:(?<=\w)\b|(?<!\w))- 右手自適應單詞邊界（如果前面的字符是非單詞字符，則不進行背景關系檢查）
