Zac*_*urt 4 javascript google-closure google-closure-library
我正在写一个基于[ libphonenumber ] 的简单电话号码解析器.不幸的是,"http://closure-library.googlecode.com/svn/trunk/closure/goog/base.js"需要永远加载,当我忘记文件并将其包含为src ="base.js"时,弹出一堆错误.
我的猜测是因为库尚未加载,所以goog.require()语句失败了.
我能做什么？

for (i in numbers) {
console.log(format_for_five9(numbers[i]));
}
function format_for_five9(phoneNumber) {
var $ = goog.dom.getElement;
var regionCode = 'US';
var output = new goog.string.StringBuffer();
try {
var phoneUtil = i18n.phonenumbers.PhoneNumberUtil.getInstance();
var number = phoneUtil.parseAndKeepRawInput(phoneNumber, regionCode);
number_json_serial = goog.json.serialize(new goog.proto2.ObjectSerializer(goog.proto2.ObjectSerializer.KeyOption.NAME).serialize(number));
number_json = goog.json.parse(number_json_serial);
if(phoneUtil.isValidNumberForRegion(number, regionCode)) {
five9_format = number_json.national_number.toString();
}
else {
five9_format = number_json.country_code.toString() + number_json.national_number.toString();
}
} catch (e) {
output.append('\n' + e);
console.log(e);

闭包库旨在与闭包编译器一起使用,以编译和缩小您的javascript以进行生产.它不打算在生产中用作原始文件.即使在您的开发环境中,您也可以使用http://plovr.com/动态编译和提供您的JavaScript.
由于类型注释和类似java的结构,闭包在原始形式中非常冗长,闭包编译器不仅会缩小脚本,还会优化和删除未使用的脚本以使事情更快.
这是使用plovr动态提供javascript代码的示例
java -Xmx256m -jar plovr.jar serve -p 9811 /path/to/your/closure/config.js
这将在localhost:9811上提供已编译的javascript文件.用于生产:
java -jar plovr.jar build /path/to/your/closure/config.js > production.js
看一下http://plovr.com/docs.html文档,了解如何配置plovr来编译或提供你的javascript.
