如何在数组中添加超链接(Javascript)

[英]How to add hyperlink in array (Javascript)

I have a random quote generator script, and I need to add hyperlinks for each quote. 我有一个随机引用生成器脚本,我需要为每个引用添加超链接。 The issue - I can't figure out how to accomplish this for the life of me. 问题-我无法弄清楚如何一生完成这项工作。

I'm a novice in javascript but after searching around, thinking there's an easy solution to my problem, I can't find a workable answer to this. 我是javascript的新手,但在四处搜寻之后,认为我的问题有一个简单的解决方案,因此找不到可行的答案。

<script type="text/javascript">
    var arr = new Array();

    arr.push("Javascript is different from Java");
    arr.push("Javascript is different from Java");
    arr.push("Javascript is different from Java");
    arr.push("CSS - Cascading Style Sheet");
    arr.push("HTML is a platform independent language");

    function rotate() {
        var num = Math.round(Math.random() * 3);
        add(num);
    }

    function add(i) {
        var chi = document.createTextNode(arr[i]);
        var tab1 = document.getElementById("add1");
        while (tab1.hasChildNodes()) {
            tab1.removeChild(tab1.firstChild);
        }
        tab1.appendChild(chi);        
    }

<table align=center style="background-color:#C0C0C0">
    <tr>
        <td background-color:#c0c0c0 align=center width=300 style="font-family:Times New Roman;">
            <b>Random Quote Generator</b>
        </td>
    </tr>
    <tr>
        <td id=add1 class=row width=300 align=center>Click Next to Display Random message</td>
    </tr>
    <tr>
        <td align=center>
            <input type=button value="Next" border=0 onclick="rotate()">

You can keep html code in your array eg 您可以将html代码保留在数组中,例如

arr.push('<a href="http://google.pl">CSS</a>');

But I don't prefer mix html code with js. 但是我不喜欢将html代码与js混合使用。 Look at my solution on JSFiddle https://jsfiddle.net/xoL2bbtd/ 在JSFiddle上查看我的解决方案https://jsfiddle.net/xoL2bbtd/

I little modified your array and add function 我稍微修改了数组并添加了功能

function add(i) {
 var chi = document.createElement('a');
 chi.textContent = arr[i].text;
 chi.setAttribute('href', arr[i].link);
 var tab1 = document.getElementById("add1");
 if (tab1.hasChildNodes()) {
  tab1.removeChild(tab1.firstChild);
 }
 tab1.appendChild(chi);
}

I create anchor element and set href attribute. 我创建锚元素并设置href属性。 In array I keep object which contains text and link property 在数组中,我保留包含文本和链接属性的对象

And one more thing. 还有一件事。 Create array by using new Array is slower than using []. 使用new Array创建数组比使用[]慢。 Check this https://jsperf.com/new-array-vs-literal/15 检查此https://jsperf.com/new-array-vs-literal/15
