PHP 表单提交会导致整个文件刷新吗? [英] Do PHP form submissions cause the whole file to refresh?

问题描述

将使用

导致用户点击提交时整个页面刷新?还是只是 PHP 部分?

Will using <form action = "<?php echo $_SERVER['PHP_SELF']; ?>" method = "post"> cause the whole page to refresh when the user clicks submit? Or just the PHP part?

推荐答案

页面通常会在提交表单后重新加载以显示提交后收到的回复形式.

The page usually will reload after submitting a form to display the response that is received after submitting the form.

为了防止这种情况，您有两种方法:

To prevent that you got two ways:

1. 在表单标签中使用target=_blank

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" target="_blank">

1. 使用 event.preventDefault(); 来阻止表单的默认操作，然后使用 fetch 手动发送数据，或者如果您使用 JQuery，您可能会使用 ajax.(我将使用 fetch 标准 API)

1. Use event.preventDefault(); to prevent the default action of form and then send data manually with fetch or if you use JQuery you might go with ajax. (I will go with fetch standard API)

document.getElementByTagName("form")[0].addEventListener('submit', function(event) {
  event.preventDefault();

  const url = 'https://randomuser.me/api';
  // The data we are going to send in our request
  const data = {
    name: 'Sara'
  }
  // The parameters we are gonna pass to the fetch function
  const fetchData = {
    method: 'POST',
    body: data,
    headers: new Headers()
  }
  fetch(url, fetchData)
    .then(function() {
      // Handle response you get from the server
    });
});
