I want to get substring from string at last index match space and put it into another string :
for example if I have : var string1="hello any body from me";
in string1 I have 4 spaces and I want to get the word after last spaces in string1 so here I want to get the word "me" ... I don't know number of spaces in string1 ... so How I can get substring from string after last seen to specific characer like space ?
You could try something like this using the split
method, where input
is your string:
var splitted = input.split(' ');
var s = splitted[splitted.length-1];
var splitted = "hello any body from me".split(' '); var s = splitted[splitted.length-1]; console.log(s);
Use split
to make it an array and get the last element:
var arr = st.split(" "); // where string1 is st
var result = arr[arr.length-1];
console.log(result);
You can use split method to split the string by a given separator, " " in this case, and then get the final substring of the returned array.
This is a good method if you want to use other parts of the string and it is also easily readable:
// setup your string var string1 = "hello any body from me"; // split your string into an array of substrings with the " " separator var splitString = string1.split(" "); // get the last substring from the array var lastSubstr = splitString[splitString.length - 1]; // this will log "me" console.log(lastSubstr); // ... // oh i now actually also need the first part of the string // i still have my splitString variable so i can use this again! // this will log "hello" console.log(splitString[0]);
This is a good method without the need for the rest of the substrings if you prefer to write quick and dirty:
// setup your string var string1 = "hello any body from me"; // split your string into an array of substrings with the " " separator, reverse it, and then select the first substring var lastSubstr = string1.split(" ").reverse()[0]; // this will log "me" console.log(lastSubstr);
Or just :
var string1 = "hello any body from me";
var result = string1.split(" ").reverse()[0];
console.log(result); // me
Thank's to reverse method
I'd use a regular expression to avoid the array overhead:
var string1 = "hello any body from me"; var matches = /\\s(\\S*)$/.exec(string1); if (matches) console.log(matches[1]);
