JS数据替换之敏感词替换为*

纯文字替换

var sensitiveWords = ['敏感词', '敏感'];    
var text = "这是一个包含敏感词和敏感的示例文本";    
let result = text;    
  
sensitiveWords.forEach(function(word) {    
    result = result.replace(new RegExp(word, 'g'), '*'.repeat(word.length));    
});    
    
console.log(result); 
// 输出："这是一个包含***和**的示例文本"

代码中包含敏感词替换

var sensitiveWords = ['敏感词', '敏感'];  
var words = document.getElementById('text');  
  
function replaceSensitiveWords(element, words) {  
    var treeWalker = document.createTreeWalker(  
        element,  
        NodeFilter.SHOW_TEXT,  
        { acceptNode: function(node) { return NodeFilter.FILTER_ACCEPT; } },  
        false  
    );  
  
    var node;  
    while(node = treeWalker.nextNode()) {  
        var text = node.nodeValue;  
        words.forEach(function(word) {  
            var regex = new RegExp(word, 'g');  
            text = text.replace(regex, '*'.repeat(word.length));  
        });  
        node.nodeValue = text;  
    }  
}  
  
replaceSensitiveWords(words, sensitiveWords);
console.log(words);
