execjs报错
爬虫，遇到几个元素是js生成的，就复制过来然后execjs执行，结果报了错：Traceback (most recent call last):
File "C:/MyPythonProjects/WebSpideFile/EnglishPlayer.py", line 22, in <module>
test = js.call('empty')

这不是重点，重点是错误内容是None,None,None......
那我上哪里改正去？
这是js代码：
var ma = /<(?:script|style|link)/i,
type = function(a) {
return null == a ? a + "" : "object" == typeof a || "function" == typeof a ? h || "object" : typeof a
},
empty = function() {
for (var a, b = 0; null != (a = this); b++) {
1 === a.nodeType && m.cleanData(ua(a, !1));
while (a.firstChild)
a.removeChild(a.firstChild);
a.options && m.nodeName(a, "select") && (a.options.length = 0)
}
a = this
return a
},
m = function(a, b) {
return new m.fn.init(a,b)
},
isFunction = function(a) {
return "function" === type(a)
},
v = access = function(a, b, c, d, e, f, g) {
var h = 0
, i = a.length
, j = null == c;
if ("object" === type(c)) {
e = !0;
for (h in c)
access(a, b, h, c, !0, f, g)
} else if (void 0 !== d && (e = !0,
isFunction(d) || (g = !0),
j && (g ? (b.call(a, d),
b = null) : (j = b,
b = function(a, b, c) {
return j.call(m(a), c)
}
)),
b))
for (; i > h; h++)
b(a, c, g ? d : d.call(a, h, b(a, c)));
return e ? a : j ? b.call(a) : i ? b(a, c) : f
}
console.log(empty())
function n(a) {
console.log(this)
return v(this, function(a) {
var b = this || {}
, c = 0
, d = this.length;
if (void 0 === a)
return 1 === b.nodeType ? b.innerHTML.replace(fa, "") : void 0;
if (!("string" != typeof a || ma.test(a) || !true && ga.test(a) || !true && ha.test(a) || ra[(ja.exec(a) || ["", ""]).toLowerCase()])) {
a = a.replace(ia, "<$1></$2>");
try {
for (; d > c; c++)
b = this || {},
1 === b.nodeType && (m.cleanData(ua(b, !1)),
b.innerHTML = a);
b = 0
} catch (e) {}
}
b && this.empty().append(a)
}, null, a, arguments.length)
}
哪一个会js的大佬来帮我看看哪里错了 原来还可以这样来获取js生成的元素
你要么把全部代码放上来，看看
