Question

所以我有几个问题需要解决。

首先，我试图解析我从html获得的这个javascript。

$（document）.ready（function（）{ $（'#commercial-show-thumbnails'）。bxSlider（{mode：'vertical'，auto： false，controls：true，pager：false，minSlides：4，maxSlides：4， moveSlides：1，slideWidth：250}）; itemSelector（'commodity-show-form'，'commodity-show-addcart-submit'， [['color'，'Choose color']，['size'，'Choose size']]，{“39805”：{ “params”：[“Smokey Blue / Mica Blue”，“36”]}，“39806”：{“params”： [“Smokey Blue / Mica Blue”，“36,5”]}，“39807”：{“params”：[“Smokey Blue / Mica Blue“，”37,5“]}，”39808“：{”params“：[”Smokey Blue / Mica 蓝色“，”38“]}，”39809“：{”params“：[”Smokey Blue / Mica Blue“， “38,5”]}，“39810”：{“params”：[“Smokey Blue / Mica Blue”，“39”]}， “39811”：{“params”：[“Smokey Blue / Mica Blue”，“40”]}，“39812”：{ “params”：[“Smokey Blue / Mica Blue”，“40,5”]}，“39814”：{“params”： [“Smokey Blue / Mica Blue”，“42”]}}， [39805,39806,39807,39808,39809,39810,39811,39812,39814]，'主推车'， “商品显示图像”）; }）;

res = re.findall(r'{ "params": (.+?)}', text)  # text is where javascript text is stored

final = [eval(i) for i in res]

print(final)

我得到了以下输出

[['Smokey Blue / Mica Blue'，'36']，['Smokey Blue / Mica Blue'，'36,5']，['Smokey Blue / Mica Blue'，'37,5']， ['Smokey Blue / Mica Blue'，'38']，['Smokey Blue / Mica Blue'，'38,5']，['Smokey Blue / Mica Blue'，'39']，[Smokey Blue / Mica Blue'，'40']，['Smokey Blue / Mica Blue'，'40,5']，['Smokey Blue / Mica Blue'，'42']]

但是现在我不知道该如何从这里开始。我想从这里找到值39805

{“39805”：{“params”：[“Smokey Blue / Mica Blue”，“36”]}。我如何解析它以便说如果我正在寻找与36相关的值，它会给我39805？

我很抱歉，但我解析时非常糟糕，我对此很陌生。

Answer 1

你可以像这样得到36：

import re
import ast

a="""$(document).ready(function() { $('#commodity-show-thumbnails').bxSlider({ mode: 'vertical', auto: false, controls: true, pager: false, minSlides: 4, maxSlides: 4, moveSlides: 1, slideWidth: 250 }); itemSelector('commodity-show-form', 'commodity-show-addcart-submit', [['color', 'Choose color'], ['size', 'Choose size']], { "39805": { "params": ["Smokey Blue/Mica Blue", "36"]}, "39806": { "params": ["Smokey Blue/Mica Blue", "36,5"]}, "39807": { "params": ["Smokey Blue/Mica Blue", "37,5"]}, "39808": { "params": ["Smokey Blue/Mica Blue", "38"]}, "39809": { "params": ["Smokey Blue/Mica Blue", "38,5"]}, "39810": { "params": ["Smokey Blue/Mica Blue", "39"]}, "39811": { "params": ["Smokey Blue/Mica Blue", "40"]}, "39812": { "params": ["Smokey Blue/Mica Blue", "40,5"]}, "39814": { "params": ["Smokey Blue/Mica Blue", "42"]} }, [39805,39806,39807,39808,39809,39810,39811,39812,39814], 'main-cart', 'commodity-show-image'); });"""
b = re.findall(r'.*?({ ".*?} }).*}', a)[0]

d1 = ast.literal_eval(b)
print d1, '\n'

for a,b in d1.iteritems():
    if b['params'][1]=='36':
        print a

输出：

{'39809': {'params': ['Smokey Blue/Mica Blue', '38,5']}, '39808': {'params': ['Smokey Blue/Mica Blue', '38']}, '39805': {'params': ['Smokey Blue/Mica Blue', '36']}, '39807': {'params': ['Smokey Blue/Mica Blue', '37,5']}, '39806': {'params': ['Smokey Blue/Mica Blue', '36,5']}, '39812': {'params': ['Smokey Blue/Mica Blue', '40,5']}, '39814': {'params': ['Smokey Blue/Mica Blue', '42']}, '39810': {'params': ['Smokey Blue/Mica Blue', '39']}, '39811': {'params': ['Smokey Blue/Mica Blue', '40']}} 

39805

Answer 2

编辑：我刚才意识到在某些情况下，大小有两个数字，如“36,5”。我认为这意味着36和半。无论如何，我的原始脚本没有考虑到这一点，这就是为什么它给出了错误的答案（我不小心注意到了。）这是一个似乎有效的修订脚本：

import re
text='''$(document).ready(function() { $('#commodity-show-thumbnails').bxSlider({ mode: 'vertical', auto: false, controls: true, pager: false, minSlides: 4, maxSlides: 4, moveSlides: 1, slideWidth: 250 }); itemSelector('commodity-show-form', 'commodity-show-addcart-submit', [['color', 'Choose color'], ['size', 'Choose size']], { "39805": { "params": ["Smokey Blue/Mica Blue", "36"]}, "39806": { "params": ["Smokey Blue/Mica Blue", "36,5"]}, "39807": { "params": ["Smokey Blue/Mica Blue", "37,5"]}, "39808": { "params": ["Smokey Blue/Mica Blue", "38"]}, "39809": { "params": ["Smokey Blue/Mica Blue", "38,5"]}, "39810": { "params": ["Smokey Blue/Mica Blue", "39"]}, "39811": { "params": ["Smokey Blue/Mica Blue", "40"]}, "39812": { "params": ["Smokey Blue/Mica Blue", "40,5"]}, "39814": { "params": ["Smokey Blue/Mica Blue", "42"]} }, [39805,39806,39807,39808,39809,39810,39811,39812,39814], 'main-cart', 'commodity-show-image'); });'''
pattern = re.compile(r' "([0-9]+).*?params.*?([0-9]+(,5)?)')

s={b:a for a,b,_ in pattern.findall(text)}

print(s['36'], s['36,5'])

现在打印39805 39806，看起来对我来说。

以下是所有数据：

for a in sorted(s):print(a, s[a])
36 39805
36,5 39806
37,5 39807
38 39808
38,5 39809
39 39810
40 39811
40,5 39812
42 39814

使用re.findall
