javascript break sentence by words
提问by THE AMAZING
Whats a good strategy to get full words into an array with its succeeding character.
将完整的单词及其后继字符放入数组中是什么好策略。
Example. This an an amazing sentence.
例子。这是一个惊人的句子。
Array(
[0] => This
[1] => is
[2] => an
[3] => amazing
[4] => sentence.
)
Elements 0 - 3 would have a succeeding space, as a period succeeds the 4th element.
元素 0 - 3 将有一个后续空格，因为句点在第 4 个元素之后。
My idea in words is to say.. Hey, i need you to split these by spacing character, Then once width of element with injected array elements reaches X, Break into a new line.
我的想法是说..嘿，我需要你按间距字符拆分这些，然后一旦注入数组元素的元素宽度达到X，就换行。
Please, gawd don't give tons of code. I prefer to write my own just tell me how you would do it.
请不要给大量的代码。我更喜欢自己写，只是告诉我你会怎么做。

Just use split:
只需使用split：
var str = "This is an amazing sentence.";
var words = str.split(" ");
console.log(words);
//["This", "is", "an", "amazing", "sentence."]
and if you need it with a space, why don't you just do that? (use a loop afterwards)
如果你需要一个空间，你为什么不这样做呢？（之后使用循环）
var str = "This is an amazing sentence.";
var words = str.split(" ");
for (var i = 0; i < words.length - 1; i++) {
words[i] += " ";
}
console.log(words);
//["This ", "is ", "an ", "amazing ", "sentence."]
Oh, and sleep well!
哦，睡个好觉！

Similar to Ravi's answer, use match, but use the word boundary \bin the regex to split on word boundaries:
与Ravi 的回答类似，使用match，但使用\b正则表达式中的词边界来分割词边界：
'This is a test. This is only a test.'.match(/\b(\w+)\b/g)
yields
产量
["This", "is", "a", "test", "This", "is", "only", "a", "test"]
or
或者
'This is a test. This is only a test.'.match(/\b(\w+\W+)/g)
yields
产量
["This ", "is ", "a ", "test. ", "This ", "is ", "only ", "a ", "test."]

try this
尝试这个
var words = str.replace(/([ .,;]+)/g,'§sep§').split('§sep§');
This will
这会
- insert a marker
§sep§after every chosen delimiter[ .,;]+ - split the string at the marked positions, thereby preserving the actual delimiters.
§sep§在每个选定的分隔符后插入一个标记[ .,;]+- 在标记的位置拆分字符串，从而保留实际的分隔符。

If you need spaces and the dots the easiest would be.
如果你需要空格和点，最简单的就是。
"This is an amazing sentence.".match(/.*?[\.\s]+?/g);
the result would be
结果是
['This ','is ','an ','amazing ','sentence.']

Here is an option if you wanted to include the space and complete in O(N)
如果您想包含空格并在 O(N) 中完成，这是一个选项
var str = "This is an amazing sentence.";
var words = [];
var buf = "";
for(var i = 0; i < str.length; i++) {
buf += str[i];
if(str[i] == " ") {
words.push(buf);
buf = "";
}
}
if(buf.length > 0) {
words.push(buf);
}
