I have a Javascript string array with values like A12, B50, C105 etc. and I want to turn it into a pipe delimited string like this: A12|B50|C105...

How could I do this? I'm using jQuery (in case that helps with some kind of builtin function).

Reset to default 60 
var pipe_delimited_string = string_array.join("|");

Array.join is a native Array method in Javascript which turns an array into a string, joined by the specified separator (which could be an empty string, one character, or multiple characters).

No need for jQuery. Use Javascripts join() method. Like

var arr = ["A12", "C105", "B50"],
    str = arr.join('|');

alert(str);

Use JavaScript 'join' method. Like this: 

Array1.join('|')

Hope this helps.

For a native JavaScript array then myArray.join('|') will do just fine.

On the other hand, if you are using jQuery and the return value is a jQuery wrapped array then you could do something like the following (untested):

jQuerySelectedArray.get().join('|')

See this article for more information.

I using [email protected]. It's very good with array and object

_.join(['a', 'b', 'c'], '~');
// => 'a~b~c'

Ref lodash

var checked = $(':input[type="checkbox"]:checked').map(function(){return this.value}).get(); console.log(checked.join(", "));

<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> 
<html> 
<head> 
<script> 
var employee = new Array(); 
employee.push("Yashwant"); 
employee.push("Dinesh"); 
employee.push("Mayur"); 
var employeeStr = employee.join("|"); 
alert('Delimited String :- ' + employeeStr); 
var employeeArray = new Array(); 
employeeArray = employeeStr.split("|"); 
for(var x=0;x<employeeArray.length;x++){ 
alert('Employee Name:- ' + employeeArray[x]); 
} 
</script>
</head> 
<body> 
</body> 
</html>
