Mar 16, 2009 · Another simple but effective method is to use split + join repeatedly. "a=b,c:d".split('=').join(',').split(':').join(',').split(',') Essentially doing a split followed by a join is like a global replace so this replaces each separator with a comma then once all are replaced it does a final split on comma. The result of the above expression is:
split() method in JavaScript is used to convert a string to an array. It takes one optional argument, as a character, on which to split. In your case (~). If splitOn is skipped, it will simply put string as it is on 0th position of an array. If splitOn is just a “”, then it will convert array of single characters.
The split() method in javascript accepts two parameters: a separator and a limit. The separator specifies the character to use for splitting the string. If you don't specify a separator, the entire string is returned, non-separated. But, if you specify the empty string as a separator, the string is split between each character. Therefore: s ...
1. As an explanation for the result that you're getting: "my, tags are, in here".split(" ,") will split the string only where a space followed by a comma is the separator. Your string does not contain that sequence, hence it is not splitted. "my, tags are, in here".split(", ") with the splitting sequence swapped will at least split your ...
A solution that works with all possible line endings including mixed ones and keeping empty lines as well can be achieved using two replaces and one split as follows. text.replace(/\r\n/g, "\r").replace(/\n/g, "\r").split(/\r/); some code to test it. var CR = "\x0D"; // \r. var LF = "\x0A"; // \n.
Other solutions I tried involving split or RegExps took a big performance hit and were about 2 orders of magnitude slower. Using join on the results of split, of course, adds an additional performance penalty. Why are they slower? Any time a new object or array has to be created, JS has to request a chunk of memory from the OS. This process is ...
You can use .split() to split a string on a specified character with the results returned as an array. So then it's just a matter of looping through the array: // given your existing variable. // feedUpdateResponse = "div1/div2/div3/div4" as set in the. // code in the question, add this:
Jul 26, 2021 · Edit: since the string.split() method also supports regex it can be achieved like this. that will also solve the problem from the comment: Update: to split on Uppercase character, not preceded with another Uppercase character, a negative lookbehind can be used. This will not find single uppercase characters.
Jul 14, 2010 · My two cents, adding trim to remove the initial whitespaces left in sAc's answer. var str = 'Hello, World, etc'; var str_array = str.split(','); for(var i = 0; i < str_array.length; i++) { // Trim the excess whitespace.
Mar 16, 2015 · const pieces = str.split(/[\s,]+/) const last = pieces[pieces.length - 1] console.log({last}) At this point, pieces is an array and pieces.length contains the size of the array so to get the last element of the array, you check pieces[pieces.length-1]. If there are no commas or spaces it will simply output the string as it was given.
