php - 如何在按下打开 php 脚本的上传按钮后保留在 .html 上？

Question

我的 .html 文件中有此代码:

<form action="upload.php" method="post" enctype="multipart/form-data">Select file to upload:        
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload file" name="submit">
</form>

我应该修改代码的哪些部分？

您需要使用ajax将文件上传到服务器:

HTML 代码:

<form action="#" method="post" enctype="multipart/form-data">Select file to upload:        
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload file" name="submitForm" name="submitForm">
</form>

jQuery 代码可能是这样的:

$('#submitForm').on('click', function() {
   var file_data = $('#fileToUpload').prop('files')[0];   
   var form_data = new FormData();                  
   form_data.append('file', file_data);                           
   $.ajax({
            url: 'upload.php', // point to server-side PHP script 
            dataType: 'text',  // what to expect back from the PHP script, if anything
            cache: false,
            contentType: false,
            processData: false,
            data: form_data,                         
            type: 'post',
            success: function(php_script_response){
                alert(php_script_response); // display response from the PHP script, if any
            }
     });
});

我很想知道这段代码是否适合您
