在HTML中使用enctype 属性来设置在提交给服务器时是否应该对表单数据进行编码。
您可以尝试运行以下代码来实现enctype 属性-
<!DOCTYPE html> <html> <body> <p>Which sports do you like?</p> <form action = "" method = "post" enctype = "multipart/form-data"> <input type = "checkbox" name = "vehicle" value = "football" checked> Football<br> <input type = "checkbox" name = "vehicle" value = "cricket" checked> Cricket<br> <input type = "checkbox" name = "vehicle" value = "hockey"> Hockey<br> <input type = "submit" value = "Submit"> </form> </body> </html>
