HTML表单内容:
<!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> <div class="box"> <p></p> </div> </body> </html>
1.textContent:
<script> const box=document.querySelector(".box"); console.log(box); const p=document.querySelector('p'); console.log(p); //textContent:添加文本 p.textContent ="hello world"; </script>
2.innerText:
<script> const box=document.querySelector(".box"); console.log(box); const p=document.querySelector('p'); console.log(p); p.innerText ="gxlsystem.com"; </script>
3.innerHTML:
<script> const box=document.querySelector(".box"); console.log(box); const p=document.querySelector('p'); console.log(p); //将html字符串渲染出来应该使用innerHTML p.innerHTML='<em style="color:red">gxlsystem.com</em>'; </script>
