我有这个字符串
'john smith~123 Street~Apt 4~New York~NY~12345'
使用JavaScript，最快的方法是什么
var name = "john smith";
var street= "123 Street";
//etc...

尽管这不是最简单的方法，但你可以这样做:
var addressString = "~john smith~123 Street~Apt 4~New York~NY~12345~",
keys = "name address1 address2 city state zipcode".split(" "),
address = {};
// clean up the string with the first replace
// "abuse" the second replace to map the keys to the matches
addressString.replace(/^~|~$/g).replace(/[^~]+/g, function(match){
address[ keys.unshift() ] = match;
});
// address will contain the mapped result
address = {
address1: "123 Street"
address2: "Apt 4"
city: "New York"
name: "john smith"
state: "NY"
zipcode: "12345"
}
更新ES2015，使用解构
const [address1, address2, city, name, state, zipcode] = addressString.match(/[^~]+/g);
// The variables defined above now contain the appropriate information:
console.log(address1, address2, city, name, state, zipcode);
// -> john smith 123 Street Apt 4 New York NY 12345

扎克是对的。使用他的方法，你也可以做出一个看似“多维”的数组。我在JSFiddle http://jsfiddle.net/LcnvJ/2/上创建了一个快速示例
// array[0][0] will produce brian
// array[0][1] will produce james
// array[1][0] will produce kevin
// array[1][1] will produce haley
var array = [];
array[0] = "brian,james,doug".split(",");
array[1] = "kevin,haley,steph".split(",");
使用JavaScript的String.prototype.split函数:
var input = 'john smith~123 Street~Apt 4~New York~NY~12345';
var fields = input.split('~');
var name = fields[0];
var street = fields[1];
// etc.
用这个代码——
function myFunction() {
var str = "How are you doing today?";
var res = str.split("/");
}
你可以使用split来拆分文本。
作为替代，你也可以使用match，如下所示
var str = 'john smith~123 Street~Apt 4~New York~NY~12345'; 匹配= str.match(/[^~]+/g); console.log(匹配); document . write(匹配);
正则表达式[^~]+将匹配除~之外的所有字符，并在数组中返回匹配的字符。然后可以从中提取匹配项。
喜欢的东西:
var divided = str.split("/~/");
var name=divided[0];
var street = divided[1];
可能是最简单的
