Jquery automatic submit - form type file

I am searching for a jQuery script 开发者_如何学运维that selects a file when the form is automatic submitted.

Try .change() event for the input file control. Something like

<form action="test.html" id="form1">
    <input type="file" id="fil1" />
</form>

$(function(){
    $("#fil1").change(function(){
        $("#form1").submit();
    });
});
