This is what it does if you use function inside, it modify selected element, so if this is what you need, you can choose this way. But if you need to take input value, store it and send to server, than you use method without function inside https://api.jquery.com/val/#val-function https://code.sololearn.com/WvMS6A5aJTVD/?ref=app

To select element by id you need to add # in selector part, if you use val without function it will return just value of input and store on some variable https://code.sololearn.com/WdOAI22qW3ok/?ref=app

$("#btnRev").click(function(){ let r="", t = $("#txt").val(); for (i=0; i<t.length; i++) { if (t[i] == t[i].toUpperCase()) r += t[i].toLowerCase(); else r += t[i].toUpperCase(); } $("#lbl").text(r); }); // I hope this code helps you. https://code.sololearn.com/WzTxUYDagkSA

Compare is val is same as val.toUpperCase() if is than it was uppercase and you turn it to lower and vice versa.

$("btn").on("click", function (){ $("txt1").Val(function (i,val) { If($(this).val===$(this).val.toLowerCase()){ return val.toUpperCase(); } else { return val.toLowerCase(); } }); }); Like this but it isn't working.
