我如何操作这个字符串[重复]

Question

我有这个挑战：

var tx =  "<p>This is a sample picture. <img src="" alt="Sample picture"> This picture is the best for the advertising...</p> ";

如何格式化这个变量来去掉img标签并得到结果：

    tx = "<p>This is a sample picture. This picture is the best for the advertising...</p> ";

Answer 1

您可以使用正则表达式来做到这一点。试试这个：

var tx =  "<p>This is a sample picture. <img src='' alt='Sample picture'> This picture is the best for the advertising...</p> ";

const res = tx.replace(/<img[^>]+>/, '');

console.log(res);
