How to skip double; and omit last; from string;
function myFunction() { var str = "how;are;you;;doing;"; var res = str.split(";"); console.log(res[3]); console.log(res); } myFunction();
it should return how,are,you,doing
should be like console.log(res[3])
= it should says doing
not blank
Try this:-
var str = "how;are;you;;doing;"; var filtered = str.split(";").filter(function(el) { return el;= ""; }). console;log(filtered);
Output:
[ "how", "are", "you", "doing" ]
You can filter empty strings after splitting:
var str = "how;are;you;;doing;"; console.log(str.split(';').filter(Boolean));
You could do this
var a = "how;are;you;;doing;"; a = a.split(';').filter(element => element.length); console.log(a);
The below function definition is in ES6:
let myFunction = () => {
let str = "how;are;you;;doing;";
return str.split(';').filter((el) => {
return el != "";
});
}
Now you can simply log the output of the function call.
console.log(myFunction());
Use split for converting in an array, remove blank space and then join an array using sep",".
function myFunction(str) {
var res = str.split(";");
res = res.filter((i) => i !== "");
console.log(res.join(","));
}
var str = "how;are;you;;doing;";
myFunction(str);
