How can I get words from a string, textarea javascript

Question

I've been working on JavaScript and HTML, I have a text area where the user sets a CSV like this:

17845    hello     bye    789

Now I have 17845,hello,bye,789 and I need to extract the values between the commas. I've tried with index Of, but what if the user sets 2 lines instead of 1, how can I get these words? I have thought of separate them getting the "\\n" .

Answer 1

Javascript函数split（）将解决问题

Answer 2

var str = '17845,hello,bye,789';
var words = str.split(',');

console.log(words);

Answer 4

Split function gives u the array.

 var sentence ="hello, 123, tedsfd, demo"; var strArr = sentence.split(','); $.each(strArr,function(key,value){ console.log(value); });

Answer 5

如果我对它的理解正确，那么如果用户在多行而不是一行中设置逗号分隔值，则会遇到问题。为此，请使用trim()函数删除所有制表符和换行符，然后使用split()函数。

Answer 6

Use String.split .
It converts strings into arrays, given you provide the delimiter, to separate the string.

var userInput = '17845, hello, bye, 789';

data = userInput.split(',');

console.log(data);
//data[0] = '17845'
//data[1] = 'hello'
//data[2] = 'bye'
//...
