url - Issue in passing argument to custom protocol through href? -

i have created custom protocol name "myapp" , trying pass arguments via href tag <a href="myapp://e:/file.txt">click here</a>.

myapp protocol described below:

[hkey_classes_root\myapp] @="\"url:alert protocol\"" "url protocol"="\"\""  [hkey_classes_root\myapp\defaulticon] @="\"c:\\windows\\system32\\notepad.exe,1\""  [hkey_classes_root\myapp\shell]  [hkey_classes_root\myapp\shell\open]  [hkey_classes_root\myapp\shell\open\command] @="\"c:\\windows\\system32\\notepad.exe\" \"%1\"" 

on clicking anchor link throws error "the filename, directory name, or volume label syntax incorrect."

i guess argument passed through <a href="myapp:e:/file.txt"> tag not getting recognized.

i have no idea how escape slashes(/) or special character here.

please,help me or let me know if doing wrong.

you have parameter also. here getting url address parameter pass in myapp:

var url = document.location.href ; var arr = url.split("/"); var result = arr[0] + "//" + arr[2] var uri='myapp://'+result;`
