如何使用GET请求在页面重载上提交表单？

Question

I want submit a form with GET request on page reload. How can I achiev this with Javascript/JQuery or without Javascript/JQuery in ASP.NET Core MVC web app. Thanks.

Answer 1

here is the code this will submit on reload

$(window).on('beforeunload', function(){
   $("form").submit();
});

or you can use URL to pass GET value

  $(window).on('beforeunload', function(){
    var v= $("input").val();
    $(location).attr('href', 'http://example.com/index.php?value='+val);
     // or window.location.href='http://example.com/index.php?value='+val;
    });

you can use ajax if above method doesn't work

$(window).unload(function(){
    $.ajax({
        type: 'GET',
        url: 'script.php',
        async:false,
        data: {value:"username"}
    });
});

if async is set to false browser waits for request to complete else it will not.

that is why above first two method may not work.
