代码:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body>
<textarea name="" id="" cols="30" rows="10" id="area"> </textarea>
<textarea name="" id="" cols="30" rows="10" id="text2"> </textarea>
<button id="btn">发布</button>
<script>
let text=document.querySelectorAll('textarea')
// console.log(text);
// console.log(text1);
let btn = document.getElementById("btn");
let reg = /金三胖|妈的/g;
btn.addEventListener("click", function () {
let newValue=text[0].value.replace(reg,'*')
console.log(newValue);
});
</script>
</body>
</html>
代码思路分析:
通过获取第一个表单的值,然后通过正则进行替换。
