如何在Javascript隨機文本數組中插入超鏈接？

Question

這是代碼：

<SCRIPT LANGUAGE="Javascript"><!--

function text() {
};

text = new text();
number = 0;

// textArray        
text[number++] = "I read the other day some verses written by an eminent painter which were original and not conventional."         
text[number++] = "The soul always hears an admonition in such lines, let the subject be what it may."        
text[number++] = "The sentiment they instil is of more value than any thought they may contain."        
text[number++] = "To believe your own thought, to believe that what is in your private heart is true for all men, that is genius." 

increment = Math.floor(Math.random() * number);

document.write(text[increment]);

//--></SCRIPT>

具體來說就是我想要的單詞：

對你來說是真的

從數組中的第四個文本鏈接到某些外部網站。

<a>標記似乎不適用於我。 字符串方法也沒有。 當然，我真是個笨蛋。

Answer 1

我猜你的問題是與行情插入，當你使用a標簽，你應該用在適當的意義引號象下面這樣：

text[number++] = "I read the other day some verses written by an eminent painter which were original and not conventional"         
text[number++] = "The soul always hears an admonition in such lines, let the subject be what it may."        
text[number++] = "The sentiment they instil is of more value than any thought they may contain."
text[number++] = "To believe your own thought, to believe that what is in your private heart is <a href='javascript:void(0);'>true for </a> all men, that is genius."

Answer 2

讓我們逐步完成此步驟，

1. 創建一個新的var叫做iable text ，並讓它成為一個數組 。

    var text = []; 

   這里的[]是數組文字 。

2. 用您的字符串填充數組 text

    text.push("I read the other day some verses written by an eminent painter which were original and not conventional."); text.push("The soul always hears an admonition in such lines, let the subject be what it may."); text.push("The sentiment they instil is of more value than any thought they may contain."); text.push("To believe your own thought, to believe that what is in your private heart is true for all men, that is genius."; 

   在這里， someArray.push是一種將新項目添加到Array someArray 。 每個新項目都有其自己的索引，索引從0開始。

3. 選擇從數組隨機指標text ，並將其分配到一個新的var iable， i

    var i = Math.floor(Math.random() * text.length); 

   在JavaScript中 ， Math.random方法返回的值嚴格小於1但大於或等於0 。 這意味着我們可以通過項目（或長度 ）的數組的數量相乘的值向上，然后向下舍入（或地板 ）此數目來選擇從所述陣列的隨機索引。

4. 在text 索引 i處的String中，將任何出現的"true for you"替換"true for you"的鏈接。 讓我們給這個var iable名str所以我們可以參考回去吧。

    var str = text[i].replace(/true for you/g, "<a href=\\"http://stackoverflow.com\\">true for you</a>"); 

   在這里， /true for you/g是正則表達式或RegExp 。 該g末代表g葉形的，意思是“繼續做下去，直到你到達終點。”

5. 以您喜歡的方式將此新的String （我們稱為str ）寫到您的#document中。 由於我們看不到與您的HTML標記有關的任何內容，因此我保留您的document.write ，但這被認為是不好的做法，因此您將來可能想學習替代方法。

    document.write(str);
