我的脚本看起来像这样。是的,它来自一个插件。不,我对 ajax 不满意。
首次提交后,如何让此表单刷新并再次输入?
<script>
jQuery(document).ready(function() { 
    var options = { 
        target: '#ps_output',      // target element(s) to be updated with server response 
        beforeSubmit:  showRequest,     // pre-submit callback 
        success:       showResponse,    // post-submit callback 
        url:           '<?php echo $link; ?>'         // since 2.8 ajaxurl is always defined in the admin header and points to admin-ajax.php     
}; 
    // bind form using 'ajaxForm' 
    jQuery('#thumbnail_upload').ajaxForm(options); 
});
function showRequest(formData, jqForm, options) {
    //do extra stuff before submit like disable the submit button
    jQuery('#ps_output').html('Sending...');
    jQuery('#submit-ajax').attr("disabled", "disabled");
}
function showResponse(responseText, statusText, xhr, $form)  {
    //do extra stuff after submit
    jQuery('#submit-ajax').attr("enabled", "enabled");
}
</script>
非常感谢。
编辑:
回调函数以die(). 我读到这仅仅是为了能够从函数中检索输出。这也结束了 AJAX 吗?
