为什么我收到错误“Uncaught TypeError: st.replace is not a function”

Question

I trying to build a portfolio. I am not a javascript expert and am not sure what to remove, or what is at fault. The page works fine but as soon as I try to go to the homepage the exit is very slow and the console throws an error.

"Uncaught TypeError: st.replace is not a function"

This snippet below is the piece that is faulty and gives me the error as soon as I click the home button to navigate away from the 'services' page.

Any instructions to as what is incorrect in the snippet are appreciated, thank you.

            htmlDoc: function(st) {
                var n, i = e(),
                    r = /<(\/?)(html|head|body|title|base|meta)(\s+[^>]*)?>/gi,
                    o = "ss" + Math.round(1e5 * Math.random()),
                    a = st.replace(r, function(t, n, r, a) {
                        var s = {};
                        return n || (e.merge(i, e("<" + r + "/>")), a && e.each(e("<div" + a + "/>")[0].attributes, function(e, t) {
                            s[t.name] = t.value
                        }), i.eq(-1).attr(s)), "<" + n + "div" + (n ? "" : ' id="' + o + (i.length - 1) + '"') + ">"
                    });
                return i.length ? (n || (n = e("<div/>")), n.html(a), e.each(i, function(e) {
                    var t = n.find("#" + o + e).before(i[e]);
                    i.eq(e).html(t.contents()), t.remove()
                }), n.children().unwrap()) : e(t)
            },

EDIT FelixKling

Thanks, @FelixKling Is seems to have several values:

"st = /-([\\da-z])/gi,"

and

" st = ":(" + rt + ")(?:((('((?:\\\\.|[^\\\\']) )'|\\"((?:\\\\.|[^\\\\\\"]) )\\")|((?:\\\\.|[^\\()[]]|" + at + ") )|. ))|)", "

and

" St = ["Top", "Right", "Bottom", "Left"], "

but the last one has a Capital letter S. Please copy paste this answer to read it more cleartly. If i need to explain some more please let me know.

Answer 1

Your issue seems to be that st is not a string. Add a verification line to the top of the function that makes sure the argument is of the type expected.

if (typeof st !== 'string') {
    // HANDLE IT HERE (throw an error, return false/null, whatever you need
}
