[javascript] How to convert array into comma separated string in javascript

I have an array

a.value = [a,b,c,d,e,f]

How can I convert to comma seperated string like

a.value = "a,b,c,d,e,f"

Thanks for all help.

You can simply use JavaScripts join() function for that. This would simply look like a.value.join(','). The output would be a string though.

Use the join method from the Array type.

a.value = [a, b, c, d, e, f];
var stringValueYouWant = a.join();

The join method will return a string that is the concatenation of all the array elements. It will use the first parameter you pass as a separator - if you don't use one, it will use the default separator, which is the comma.
