Someone helped me find JavaScript code to remove hidden form fields from submission and code that ignores a certain field that I don't want removed (whether it's hidden or not):

$("form").submit(function() {
$(this).find(":hidden").remove(); // hide hidden elements before submitting
});

and

:not(input[name=csrfmiddlewaretoken])

However, I can't for the life of me figure out how to put these together. I'm sure it's a basic JavaScript question, but I can't seem to piece these together.

Does anyone know how to remove all hidden form entries not named csrfmiddlewaretoken? If you do, I'd really appreciate it.

Thanks a lot.

$(this).find(":hidden").not('input[name=csrfmiddlewaretoken]').remove();

Or

$(this).find(":hidden").filter(':not(input[name=csrfmiddlewaretoken])').remove();

Or

$(this).find("input[name!=csrfmiddlewaretoken]:hidden").remove();

$(this).find(":hidden").filter("[name!='csrfmiddlewaretoken']").remove();

You can pass the this as a context argument, which will be potentially faster than making a jQuery object from it. The :not() expression can follow the :hidden without spaces, meaning that it adds a second condition to the :hidden selector.

$(":hidden:not(input[name=csrfmiddlewaretoken])", this).remove();
