谁解码这段代码？

解决方案代码（我不知道可能不是）：

        opt = opt || {};
        opt.whitespace = opt.whitespace === true;
    }

    var separator = " = ";

    Object.keys(obj).forEach(function (k, _, __) {
        var val = obj[k];
        if (val && Array.isArray(val)) {
            val.forEach(function(item) {
                out += safe(k + "[]") + separator + safe(item) + "\n";

请帮助 - 我尝试了一些Hex解码网站，但没有成功。

_0xe153是

从base64解码的

_0xe153[1]为setscr.php

所以如果重写代码就是

userScore = Math.max(userScore, calcUserScore());
$.post('setscr.php', {
    s: userScore
}, function(_0x12dfx1, _0x12dfx2) {
    $('#levelbar').html(_0x12dfx1)
});
Qs();
wjQuery("#statoverlay").show();
wjQuery("#stats").fadeIn(arg ? 200 : 3E3);
