Focus 和 Blur 在测试服务器上不起作用

Question

I have Contact Us form using ASP.Net Core 6 MVC with client JQuery validation. I'm using the jquery focus and blur methods which works perfectly on localhost using VS2022 however when publishing the procject and copying the files to a test sever on windows 2012 r2 and iis 8.5 the focus and blur methods don't work.

I'm not sure why this is not working. Any help would be much appreciated.

Thanks,

Answer 1

I was able to fix the issue by placing the jquery in the function below

$(function () {
    var inputFields = $("input:text, textarea");
    inputFields.css("border-color", "rgba(102,102,102,0.5)");

    inputFields.focus(function () {
        $(this).css("box-shadow", "0 0 0 0.2rem rgba(102, 102, 102, 
        0.25)").css("border-color", "rgba(102,102,102,0.5)");
     });

     inputFields.blur(function () {
        $(this).css("box-shadow", "none").show();
     });
});
