jQuery表单插件reset（）

I'm using http://malsup.com/jquery/form/

very simple, how do I make it so it submits then resets my form? I know next to nothing about ajax

Using jQuery - this will reset all text fields (text and passwords). If you need to reset other fields (checkboxes...) you will need to clear those also:

    $(document).ready(function() { 
       // bind 'myForm' and provide a simple callback function 
        $('#myForm').ajaxForm(function() { 
            alert("Thank you for your comment!"); 
            $('#myForm').find("input[type=text] input[type=password], textarea").val("");
        }); 
    }); 

$(".submit").click(function() {
    $(this).closest('myForm').find("input[type=text], textarea").val("");
});

or

$('#myForm')[0].reset();

or

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

You can use the HTML DOM Form reset() function:

Usage

...
// Selects the first (index 0) #myForm element and calls the reset method
// (the reset method is available to any HTML DOM form element)
$('#myForm')[0].reset();
...

After your submit or success of your ajax call add something like:

$("#form").submit(function(){
    //your ajax call
    $("#forum")[0].reset();// or document.getElementById("forum").reset();
}

or:

$.ajax({
    ...
    success: function(...){
        $("#forum")[0].reset();// or document.getElementById("forum").reset();
    }
});
