用于邮政编码验证的Javascript

Question

我正在尝试让Javascript验证用户输入的邮政编码。

如果它在有效邮政编码列表中，则应将其带到新页面以安排约会。如果邮政编码不在列表中，则应显示一条消息，表明服务区域未覆盖该邮政编码，然后将其保留在页面上。

如果它有效，我可以将它带到约会页面的位置，但如果它没有效，它也会将它们带到约会页面。

你们介意帮我搞清楚吗？

以下是运行Javascript的页面：http://platinumfactoryservice.com/service-area/

以下是代码：

<script type = "text/javascript">

function checkZip() {

var z = document.myform.zip;
var zv = z.value;
if (!/^\d{5}$/.test(zv)) {
alert ("Please enter a valid Zip Code");
document.myform.zip.value = "";
myfield = z;  // note myfield must be a global variable
setTimeout('myfield.focus(); myfield.select();' , 10);  // to fix bug in Firefox
return false;
}

var codes = [26003,26030,26031,26032,26035,26036,26037,26038,26039,26040,26041,26058,26059,26060,26062,26070,26074,26075,43713,43716,43718,43719,43747,43750,43757,43759,43768,43773,43778,43902,43905,43906,43909,43912,43913,43915,43916,43917,43927,43928,43933,43934,43935,43937,43938,43939,43940,43941,43942,43943,43947,43948,43950,43951,43952,43953,43963,43967,43971,43972,43977,43985,15004,15017,15018,15019,15021,15025,15028,15031,15034,15035,15045,15046,15047,15053,15054,15055,15056,15057,15060,15064,15071,15078,15081,15082,15088,15102,15104,15106,15108,15110,15112,15116,15120,15122,15123,15126,15127,15129,15131,15132,15133,15134,15135,15136,15137,15139,15140,15142,15143,15145,15146,15147,15148,15201,15202,15203,15204,15205,15206,15207,15208,15209,15210,15211,15212,15213,15214,15215,15216,15217,15218,15219,15220,15221,15222,15223,15224,15225,15226,15227,15228,15229,15230,15231,15232,15233,15234,15235,15236,15237,15239,15240,15241,15242,15243,15244,15250,15251,15252,15253,15254,15255,15257,15258,15259,15260,15261,15262,15264,15265,15267,15268,15270,15272,15274,15275,15276,15277,15278,15279,15281,15282,15283,15286,15289,15290,15295,15301,15312,15317,15321,15323,15339,15340,15342,15350,15361,15363,15365,15367,15376,15378,15379,15347,15330,23705,23703,23707,23708,23704,23709,23702,23701,23326,23328,23327,23322,23325,23320,23324,23323,23321,23520,23519,23541,23512,23551,23515,23529,23506,23501,23514,23521,23518,23502,23503,23505,23513,23509,23504,23508,23511,23517,23510,23507,23523,23459,23458,23450,23479,23471,23466,23467,23465,23463,23461,23451,23460,23456,23452,23455,23454,23453,23462,23464,23457,23261,23291,23260,23225,23221,23249,23222,23223,23241,23232,23224,23290,23173,23298,23273,23274,23289,23279,23282,23276,23278,23295,23219,23218,23220,23269,23286,23292,23293,23285,23284,23228,23227,23226,23229,23075,23231,23230,23294,23289,23060,23059,23075,23288,23242,23238,23250,23233,23255,23150,23058,23234,23831,23235,23237,23236,23836,23114,23112,23113,23297,23832,23120,23838,23801,23803,23804,23805,23806,23834,23111,15004,15017,15018,15019,15021,15025,15028,15031,15034,15035,15045,15046,15047,15053,15054,15055,15056,15057,15060,15064,15071,15078,15081,15082,15084,15088,15102,15104,15106,15108,15110,15112,15116,15120,15122,15123,15126,15127,15129,15131,15132,15133,15134,15135,15136,15137,15139,15140,15142,15143,15145,15146,15147,15148,15201,15202,15203,15204,15205,15206,15207,15208,15209,15210,15211,15212,15213,15214,15215,15216,15217,15218,15219,15220,15221,15222,15223,15224,15225,15226,15227,15228,15229,15230,15231,15232,15233,15234,15235,15236,15237,15239,15240,15241,15242,15243,15244,15250,15251,15252,15253,15254,15255,15257,15258,15259,15260,15261,15262,15264,15265,15267,15268,15270,15272,15274,15275,15276,15277,15278,15279,15281,15282,15283,15286,15289,15290,15295,15301,15312,15317,15321,15323,15339,15340,15342,15350,15361,15363,15365,15367,15376,15378,15379,15347,15330,43711,43717,43722,43723,43724,43725,43732,43736,43772,43778,43779,43780,43788,25504,25510,25526,25537,25541,25545,25559,25571,25701,25702,25703,25704,25705,25706,25707,25708,25709,25710,25711,25712,25713,25714,25715,25716,25717,25718,25719,25720,25721,25722,25723,25724,25725,25726,25727,25728,25729,25755,25770,25771,25772,25773,25774,25775,25776,25777,25778,25779,41101,41102,41105,41114,41129,41139,41169,41183,45619,45619,45623,45638,45645,45669,45675,45680,25011,25026,25033,25070,25082,25109,25112,25124,25143,25156,25159,25168,25177,25213,25334,25338,25357,25375,25389,25560,25569,25003,25015,25025,25035,25039,25045,25054,25061,25064,25067,25071,25075,25079,25083,25086,25102,25103,25107,25110,25126,25132,25134,25160,25162,25201,25202,25214,25301,25302,25303,25304,25305,25306,25309,25311,25312,25313,25314,25315,25317,25320,25321,25322,25323,25324,25325,25326,25327,25328,25329,25330,25331,25332,25333,25335,25336,25337,25339,25350,25356,25358,25360,25361,25362,25364,25365,25387,25392,25396,15001,15003,15005,15009,15010,15026,15027,15042,15043,15050,15052,15059,15061,15066,15074,15077,15081,16123,16136,16101,16102,16103,16105,16107,16108,16112,16115,16116,16117,16120,16121,16123,16132,16140,16141,16142,16143,16146,16148,16150,16155,16156,16157,16159,16160,16161,16172,44401,44403,44405,44406,44416,44418,44420,44422,44424,44425,44429,44430,44436,44437,44438,44440,44442,44443,44446,44451,44452,44454,44470,44471,44473,44481,44482,44483,44484,44485,44486,44488,44501,44502,44503,44504,44505,44506,44507,44509,44510,44511,44512,44513,44514,44515,44555,44619,44672,16001,16002,16003,16016,16017,16018,16020,16021,16022,16023,16024,16025,16027,16029,16030,16033,16034,16035,16037,16038,16039,16040,16041,16045,16046,16048,16050,16051,16052,16053,16055,16056,16057,16059,16061,16063,16066,15006,15007,15014,15015,15024,15030,15032,15037,15044,15049,15051,15065,15075,15076,15086,15090,15091,15101,15144,15238,44609,44701,44702,44703,44704,44705,44706,44707,44708,44709,44710,44711,44714,44718,44720,44720,44721,44730,44730,44735,44750,44767,44799,44601,44646,44647,44648,44608,4

Answer 1

将onsubmit="checkZip()"更改为onsubmit="return checkZip()"，因为此时您的表单始终已提交。
