I have 3 strings "a","b","c" in javascript array "testarray".
var testarray=new Array("a","b","c");
and then I am printing the value of testarray using javascript alert box.
alert(testarray);
The result will be like a,b,c
All these strings are separated by "," character. I want to replace this "," with some other character or combination of two or more characters so that the alert box will show something like a%b%c or a%$b%$c
Use the join method:
alert(testarray.join("%")); // 'a%b%c'
Here's a working example. Note that by passing the empty string to join you can get the concatenation of all elements of the array:
alert(testarray.join("")); // 'abc'
Side note: it's generally considered better practice to use an array literal instead of the Array constructor when creating an array:
var testarray = ["a", "b", "c"];
you can iterate through the array and insert your characters
var testarray=new Array("a","b","c");
var str;
for (var i = 0; i < testarray.length; i++) {
str+=testarray[i]+"%";
}
alert(str);
use testarray is getting converted in string using testarray.toString() before alert. toString internally joining these items using ',' as separator. you can convert it into string using Array.join and pass own separator.
alert(testarray.join("%"));
var testarray= ["a","b","c"]rather thanvar testarray=new Array("a","b","c");it reads easier an avoids a few potential issues.
