我们使用以下格式化数据获取PDF格式。
14424, 14(100-103,706), 1488(zip 5-6,3),14(100-103,706,715,402-408,112),ect...
我需要获取该数据并解析出来以生成给定的邮政编码
14424,14100,14101,14102,14103,14706,14885,14886,14883
$('form').submit(function(e) {
$('textarea').val(parse_zip($('textarea').val()));
e.preventDefault();
});
function parse_zip(zip_codes) {
var valid = true;
var formated = zip_codes.replace(/[^\d()\-,]+/g, '');
var final_result = '';
/*if begins with digit*/
if (/^\d/.test(formated)) {
final_result = formated;
} else {
final_result = formated;
valid = false;
}
if (valid) {
return final_result;
} else {
return final_result + ' = Invalid';
}

我该如何解析这个？
修改
我已经开始解析项目了，但是我遇到了一些绊脚石。这是我到目前为止所做的。
function rangeParser(zip_codes) {
var valid = true;
var formated = zip_codes.replace(/[^\d()\-,]+/g, '');
var final_result = '';
/*if begins with digit*/

var newString = '';
var openLeft = false;
for (var i = 0, len = formated.length; i < len; i++) {
if (formated[i] === '(') {
if (openLeft) {
/*if two left parentheses are open, then it's invalid*/
valid = false;
break;
} else {
openLeft = true;
}
} else if (formated[i] === ')') {
if (openLeft) {
openLeft = false;
} else {
/*if no left parentheses are open and you close it with a right parenthese, the it's invalid*/
valid = false;
break;
}
} else if (formated[i] === ',') {
if (openLeft) {
/*if you are between parentheses then use the '|' as a deliminator to be split latter*/
newString += '|';
} else {
newString += ',';
}
} else {

}
}
if (valid) {
/*splits the string into seperate equations*/
var newArray = newString.split(',');
var append = '';
var substr = [];

append = /^\d+/.exec(newArray[i])[0];
/*gets the string that will be parsed for generating automation*/
substr = newArray[i].substring(append.length).replace(/[^\d\-|,]+/g, '').split('|');
for (var j = 0, l = substr.length; j < l; j++) {
smsplit = substr[j].split('-');
if (smsplit.length === 2 && parseInt(smsplit[0]) < parseInt(smsplit[1])) {
if (parseInt(smsplit[0]) < parseInt(smsplit[1])) {

答案 0 :(得分：1)
这是一个基本的答案，我很想知道是否有人可以提出比我更好的答案，那就是预备它。
