javascript中的随机字母颜色

Question

我正在尝试创建一个脚本，为我网站上“p”标签内的每个字母提供随机颜色。着色部分工作正常，问题是我的脚本覆盖了“br”和“a”标签。有什么解决方法吗？

到目前为止，这是我的代码：

function changeColor() {
    var paragraphs = document.getElementsByTagName("p");
   
    for(var i = 0; i < paragraphs.length; i++)
    {
        var innerText = paragraphs[i].innerText;
        var innerTextSplit = innerText.split("");
        paragraphs[i].innerText = ""
       
        for(var j = 0; j < innerTextSplit.length; j++) {
            var randomColor = "rgb(" + Math.floor((Math.random() * 255) + 1) + ", " + Math.floor((Math.random() * 255) + 1) + ", " + Math.floor((Math.random() * 255) + 1) + ");"
 
            innerTextSplit[j] = '<span style="color: ' + randomColor + '">' + innerTextSplit[j] + '</span>';
            paragraphs[i].innerHTML += innerTextSplit[j];
        }
    }
}

非常感谢任何帮助，在此先感谢:)

请在sn-p下面找到一个函数getRandomColor()用于生成随机颜色的六进制代码

$(function(){
changeColor();
});

function changeColor() {
    var paragraphs = document.getElementsByTagName("p");
   
    for(var i = 0; i < paragraphs.length; i++)
    {
        var innerText = paragraphs[i].innerText;
        var innerTextSplit = innerText.split("");
        paragraphs[i].innerText = ""
       
        for(var j = 0; j < innerTextSplit.length; j++) {
            var randomColor =getRandomColor();
 
            innerTextSplit[j] = '<span style="color: ' + randomColor + '">' + innerTextSplit[j] + '</span>';
            paragraphs[i].innerHTML += innerTextSplit[j];
        }
    }
}

function getRandomColor() {
    var letters = '0123456789ABCDEF';
    var color = '#';
    for (var i = 0; i < 6; i++ ) {
        color += letters[Math.floor(Math.random() * 16)];
    }
    return color;
}

不优雅，但试试：

function changeColor() {
var paragraphs = document.getElementsByTagName("p");

for(var i = 0; i < paragraphs.length; i++)
{
    var innerText = paragraphs[i].innerHTML;
    var innerTextSplit = innerText.split("");
    paragraphs[i].innerText = "";

    var isHTMLElement = false;

    for(var j = 0; j < innerTextSplit.length; j++) {
        if(innerTextSplit[j] == "<")
          isHTMLElement = true;

        if(!isHTMLElement){
          var randomColor = "rgb(" + Math.floor((Math.random() * 255) + 1) + ", " + Math.floor((Math.random() * 255) + 1) + ", " + Math.floor((Math.random() * 255) + 1) + ");"
          innerTextSplit[j] = '<span style="color: ' + randomColor + '">' + innerTextSplit[j] + '</span>';
        }

        if(innerTextSplit[j] == ">")
            isHTMLElement = false;

    }

    innerTextSplit = innerTextSplit.join('');
    paragraphs[i].innerHTML += innerTextSplit;
}
}
