javascript - 替换功能有问题

Question

能否请告诉我为什么我无法在此示例中将 / 替换为 >

var str = document.getElementById("demo").innerHTML; 
    var res = str.replace('/', ">");
    document.getElementById("demo").innerHTML = res;

<p id="demo">Change &#47;</p>

Answer 1

因为 / 被转换为真实字符 (/)。请尝试如下:

var str = document.getElementById("demo").innerHTML; 
    var res = str.replace('/', ">");
    document.getElementById("demo").innerHTML = res;

<p id="demo">Change &#47;</p>
