Question

你好所有我试图制作一个邮政编码检查器JavaScript函数，检查文本字段与邮政编码数组，如果文本包含数组中的邮政编码，它说我们无法传递给你，如果它没有显示在列表中那么它说我们可以交付给你，这是我到目前为止的代码。

   <script>

        var postcodes = "AB1, AB2, AB23, AB3, AB30, AB31, AB32, AB33, AB34, AB35, AB36, AB41, AB42, AB43, AB44, AB45, AB51, AB52, AB53, AB54, AB55, DD10, DD9, DD10, DD11, DD2, DD3, DD4, DD5, DD7, DD8, DD9, PH11, PH12, FK17, G82, G83, G84, PA20, PA21, PA22, PA23, PA24, PA25, PA26, PA27, PA28, PA29, PA30, PA31, PA32, PA33, PA34, PA35, PA36, PA37, PA38, PA41, PA42, PA43, PA44, PA45, PA46, PA47, PA48, PA49, PA60, PA61, PA62, PA63, PA64, PA65, PA66, PA67, PA68, PA70, PA71, PA72, PA73, PA74, PA75, PA76, PA77, PA78, DG7, KA1, KA10, KA11, KA12, KA13, KA14, KA15, KA16, KA17, KA18, KA19, KA2, KA20, KA21, KA22, KA23, KA24, KA25, KA26, KA27, KA28, KA29, KA3, KA30, KA4, KA5, KA6, KA7, KA8, KA9, PA17, FK10, FK11, FK12, FK13, FK14, DG1, DG10, DG11, DG12, DG13, DG14, DG16, DG2, DG3, DG4, DG5, DG6, DG7, DG8, DG9, KA6, ML12, G60, G61, G62, G64, G65, G66, G81, G82, G83, DD1, DD2, DD3, DD5, EH21, EH22, EH31, EH32, EH33, EH34, EH35, EH36, EH39, EH40, EH41, EH42, TD13, EH1, EH10, EH12, EH13, EH14, EH15, EH16, EH17, EH2, EH20, EH21, EH28, EH29, EH3, EH30, EH4, EH5, EH6, EH7, EH8, EH9, FK1, FK10, FK11, FK12, FK13, FK14, FK15, FK16, FK17, FK18, FK19, FK2, FK20, FK21, FK3, FK4, FK5, FK6, FK7, FK8, FK9, DD6, FK10, KY1, KY10, KY11, KY12, KY13, KY14, KY15, KY16, KY2, KY3, KY4, KY5, KY6, KY7, KY8, KY9, G1, G11, G12, G14, G15, G2, G20, G21, G32, G41, G43, G45, G51, G53, G76, AB37, IV1, IV10, IV11, IV12, IV13, IV14, IV15, IV16, IV17, IV18, IV19, IV2, IV20, IV21, IV22, IV23, IV24, IV25, IV26, IV27, IV28, IV3, IV4, IV40, IV41, IV42, IV43, IV44, IV45, IV46, IV47, IV48, IV49, IV5, IV51, IV52, IV53, IV54, IV55, IV56, IV6, IV7, IV8, IV9, KW1, KW10, KW11, KW12, KW13, KW14, KW2, KW3, KW5, KW6, KW7, KW8, KW9, PA34, PA38, PA39, PA40, PH19, PH20, PH21, PH22, PH23, PH24, PH25, PH26, PH30, PH31, PH32, PH33, PH34, PH35, PH36, PH37, PH38, PH39, PH40, PH41, PH42, PH43, PH44, PA10, PA11, PA13, PA14, PA16, PA18, PA19, EH46, EH55, G33, G65, G66, G67, G68, G69, G71, G72, G73, G74, G75, ML1, ML10, ML11, ML12, ML2, ML3, ML4, ML5, ML6, ML7, ML8, ML9, EH10, EH18, EH19, EH20, EH22, EH23, EH24, EH25, EH26, EH37, EH46, AB37, AB38, AB56, IV30, IV31, IV32, IV36, PH26, KW1, KW15, KW16, KW17, DD2, FK14, FK15, FK19, FK21, KY13, PH1, PH10, PH11, PH12, PH13, PH14, PH15, PH16, PH17, PH18, PH2, PH3, PH4, PH5, PH6, PH7, PH8, PH9, G46, G77, G78, PA1, PA10, PA11, PA12, PA14, PA3, PA4, PA5, PA6, PA7, PA8, PA9, EH26, EH38, EH43, EH44, EH45, EH46, ML12, TD1, TD10, TD11, TD12, TD13, TD14, TD15, TD2, TD3, TD4, TD5, TD6, TD7, TD8, TD9, ZE1, ZE2, ZE3, FK15, FK16, FK17, FK18, FK19, FK20, FK21, FK6, FK7, FK8, FK9, G63, EH27, EH30, EH47, EH48, EH49, EH52, EH53, EH54, EH55, HS1, HS2, HS3, HS4, HS5, HS6, HS7, HS8, HS9"
