如何拆分每个单词和空格？

Question

I'm trying to split simple contentText(from a span element) with white spaces but for some reason it doesn't split all white spaces.

My algorithm is working properly with the other elements like input texts. Did some research for hours now but I couldn't find the result that I need.

var list_topic = table.find('.list_topic')[0].textContent;
var check_topic = list_topic.split(" ");
console.log(check_topic);

The code above returns:

["    ","word ","word    ","word","  ","word "]

Desired Output"

["","","","","","word","","word","","","","","word","","","","word",""]```

Answer 1

You could take a regular expression which looks for white space.

 var string = ' word word word \\nword'; console.log(string.split(/\\s/)); 

Answer 2

Try this:

var check_topic = list_topic.split("");
for (var i = 0; i < check_topic) {
    if (check_topic[i] == " ") {
        check_topic[i] = "";
    } else if (check_topic[i-1] != "") {
        check_topic[i-1] += check_topic[i];
        check_topic.splice(i,1);
    }
}

This takes a string and splits it by every single character. If it's whitespace, then it removes it and makes it "" instead of " ". Then, if it's not, AND the last one in the array isn't, it joins the 2. So, something like word would look like this:

[" ", "w","o","r","d"]
["", "w","o","r","d"]
["", "wo","r","d"]
["", "wor","d"]
["", "word"]
