Javascript Split string on UpperCase Characters
提问by Nicholas Murray
How do you split a string into an array in Javascript by UpperCase character?
你如何通过大写字符将字符串拆分为Javascript中的数组？
So I wish to split:
所以我想拆分：
'ThisIsTheStringToSplit'
into
进入
('This', 'Is', 'The', 'String', 'To', 'Split')
回答by Teneff
I would do this with .match()like this:
我会这样做.match()：
'ThisIsTheStringToSplit'.match(/[A-Z][a-z]+/g);
it will make an array like this:
它将创建一个这样的数组：
['This', 'Is', 'The', 'String', 'To', 'Split']
edit:since the string.split()method also supports regex it can be achieved like this
编辑：由于该string.split()方法也支持正则表达式，所以可以这样实现
'ThisIsTheStringToSplit'.split(/(?=[A-Z])/); // positive lookahead to keep the capital letters
that will also solve the problem from the comment:
这也将解决评论中的问题：
"thisIsATrickyOne".split(/(?=[A-Z])/);

.match(/[A-Z][a-z]+|[0-9]+/g).join(" ")
This should handle the numbers as well.. the join at the end results in concatenating all the array items to a sentence if that's what you looking for
这也应该处理数字..最后的连接会导致将所有数组项连接成一个句子，如果这就是你要找的
'ThisIsTheStringToSplit'.match(/[A-Z][a-z]+|[0-9]+/g).join(" ")
Output
输出
"This Is The String To Split"

Here you are :)
这个给你 ：）
var arr = UpperCaseArray("ThisIsTheStringToSplit");
function UpperCaseArray(input) {
var result = input.replace(/([A-Z]+)/g, ",").replace(/^,/, "");
return result.split(",");
}
