如何在SUBMIT AJAX之后清除FORM

标签： jquery ajax forms

我已经尝试了所有人一直在说的内容，但我无法在提交后重置表单。除此部分外，其他所有工作都有效。只是希望表单在全部运行后重新设置。谢谢！

<script>
$("#contactForm").submit(function(e) {
	e.preventDefault();
	var Name = $("#Name").val();
	var Phone = $("#Phone").val();
	var Company = $("#Company").val();
	var Website = $("#Website").val();
	var Service = $("#Service").val();
	var Message = $("#Message").val();
	var myData ={"Name":Name,"Phone":Phone,"Company":Company,"Website":Website,"Service":Service,"Message":Message}
	if(Name == "" || Phone == "" || Company == "" || Website == "" || Service == "" || Message == "" ) {
		$("#error_message").show().html("All Fields are Required");
	} else {
		$("#error_message").html("").hide();
		$.ajax({
			type: "POST",
			url: "submitAjax.php",
			data: myData,
			success: function(data){
				$("#contactForm").reset();
				$('#success_message').fadeIn().html(data);
				setTimeout(function() {
					$('#success_message').fadeOut("slow");
				}, 2000 );
				

			}
		});
	}
})
</script>

简单 

$("#contactForm")[0].reset();

或在香草javascript：

document.getElementById("#contactForm").reset();

您可以触发重置功能：

$('#form_id').trigger("reset");

您的代码应如下所示

<script>
$("#contactForm").submit(function(e) {
    e.preventDefault();
    var Name = $("#Name").val();
    var Phone = $("#Phone").val();
    var Company = $("#Company").val();
    var Website = $("#Website").val();
    var Service = $("#Service").val();
    var Message = $("#Message").val();
    var myData ={"Name":Name,"Phone":Phone,"Company":Company,"Website":Website,"Service":Service,"Message":Message}
    if(Name == "" || Phone == "" || Company == "" || Website == "" || Service == "" || Message == "" ) {
        $("#error_message").show().html("All Fields are Required");
    } else {
        $("#error_message").html("").hide();
        $.ajax({
            type: "POST",
            url: "submitAjax.php",
            data: myData,
            success: function(data){
                $("#contactForm").trigger("reset"); //reset form
                $('#success_message').fadeIn().html(data);
                setTimeout(function() {
                    $('#success_message').fadeOut("slow");
                }, 2000 );


            }
        });
    }
})
</script>

即使在 document.getElementById("#contactForm").reset(); 之后，表单值仍然存在。

$(document).ready(function () {

$("#instantPrint").click(function (event) {

    //stop submit the form, we will post it manually.
    event.preventDefault();

    // Get form
    var form = $('#submitForm')[1];

   // Create an FormData object 
    var data = new FormData(form);


   // disabled the submit button
    $("#instantPrint").prop("disabled", true);

    $.ajax({
        type: "POST",
        enctype: 'multipart/form-data',
        url: '../card/card/print',
        data: data,
        processData: false,
        contentType: false,
        cache: false,
        timeout: 800000,
        success: function (data) {
          // $("#submitForm").trigger("reset");
          document.getElementById("#submitForm").reset();

            // // $("#output").text(data);
            // // console.log("SUCCESS : ", data);
            // // $("#instantPrint").prop("disabled", false);
            // alert("Saved Successfully");
           

        },
        error: function (e) {

        //     $("#output").text(e.responseText);
        //     console.log("ERROR : ", e);
        //     $("#instantPrint").prop("disabled", false);

        // }
        alert("Unable to Save ");
    });
  

});

});

 $(".yourForm").on("submit", function (e) {
    e.preventDefault();
    const dataString = $(this).serialize();
    const self = this;

    $.ajax({
        type: "POST",
        url: "/post",
        data: dataString,
        async: true,
        success: (res) => {
            // do something
            self.reset();
        }
    });

    return false;
