Word js：matchCase 搜索選項未按預期工作

Question

我正在嘗試搜索一個初始大寫的單詞，但 matchCase 搜索選項未按預期工作。 下面是我的代碼：

textToHighlight = "Deed";
var rangeCol = para.search(textToHighlight, { matchCase: true});

段落文本：賣方應以信函（“契約”）的形式通過授予契約將財產所有權轉讓給買方。

它總是返回非上限的第一個契約實例。

謝謝

請參閱下面的代碼段，它按預期工作。 你在嘗試做其他事情嗎？

 let para = "[...] to Buyer by grant deed in the form of letter" textToHighlight = "Deed"; var rangeCol = para.search(textToHighlight, { matchCase: true}); console.log(rangeCol); // -1, not found para = "[...] to Buyer by grant Deed in the form of letter" textToHighlight = "Deed"; var rangeCol = para.search(textToHighlight, { matchCase: true}); console.log(rangeCol); // 24, found

在用香草 JavaScript 突出顯示文本方面，我想出了以下內容：

 let _text = text.innerText; button.addEventListener("click", () => { text.innerText = _text; let textToHighlight = input.value; var rangeCol = text.innerText.search(textToHighlight, { matchCase: true, }); let node = text.childNodes[0]; let spaces = node.textContent.match(/^\s*/)[0].length; let range = new Range(); range.setStart(node, spaces + rangeCol); range.setEnd(node, spaces + rangeCol + textToHighlight.length); const mark = document.createElement("mark"); range.surroundContents(mark); });

 #text { margin: 10px 0; } mark { background-color: yellow; }

 <div id="text"> Seller shall convey title to the Property to Buyer by grant deed in the form of letter("Deed"). </div> <input id="input" type="text" /> <button id="button">Highlight</button>
