Question

这是通过HTML页面的密码恢复表单，该表单通过AJAX将数据发布到PHP文件。该代码一切正常，但一旦提交并获得响应，则不会清除表单输入字段。在过去的4个小时里，我一直在网上搜索，发现有太多的代码行可以这样做，但是似乎都行不通。请帮我解决这个问题:)祝你有美好的一天。

$(function() {
/////////////////////////////////////////////////////////'Form ID' & 'Element Name' /////////////////////////////////////////
	// Get the form.
	var form = $('#emailform');

	// Get the messages div.
	var formMessages = $('#formresults');

	// Set up an event listener for the contact form.
	$(form).submit(function(e) {
		// Stop the browser from submitting the form.
		e.preventDefault();

		// Serialize the form data.
		var formData = $(form).serialize();

		// Submit the form using AJAX.
		$.ajax({
			type: 'POST',
			url: $(form).attr('action'),
			data: formData
		})
		
		.done(function(response) {
			
			// Make sure that the formMessages div has the 'success' class.
			$(formMessages).removeClass('error');
			$(formMessages).addClass('success');
			// Set the message text.
			$(formMessages).text(response);

			// Clear the form.
//			$('#email1').val('');
         //var email = $('input[name=#email]').val("");
		 //document.getElementById("emailform").reset();
		 //$('#emailform')[0].reset();
		 //$('input:text').val('');
		  //$('#emailform input[type=text]').val('');
		    //setTimeout(function(){
            //$('input,textarea','#emailform').val(''); //clearing inputs
			//},1);


			
		})
		.fail(function(data) {
			// Make sure that the formMessages div has the 'error' class.
			$(formMessages).removeClass('success');
			$(formMessages).addClass('error');

			// Set the message text.
			if (data.responseText !== '') {
				$(formMessages).text(data.responseText);
			} else {
				$(formMessages).text('Oops! An error occured and your message could not be sent.');
			}
		});

	});

});

Answer 1

您可以在表单元素上使用JavaScript的.reset()函数，这将清除所有输入字段。

Answer 2

我找到了答案，只是删除了http_response_code（）对于所有的陈述。
