Another trick to check read mode / edit mode

Type the following code text on your form and make it as pass-thru HTML. Remember! don't type <computed text> between quote at editMode js variable <computed text> formula it should be @isdocbeingedited check read / edit mode is just one benefit we can reach from <computed text>, pass-thru HTML text and formula from Lotus Domino. Now, we can eliminate unneccessary hidden field and use a javascript variable combine formula for front-end programming.

 <script>
editMode = "<computed text>"
//type "@isdocbeingedited" formula.

if (editMode == 1) {
   alert("you are in edit mode")
} else {
   alert("you are in read mode")
}
</script>
