I'm trying to replace the value of item
with values in the array arr
, but I only get that if I use: arr [1]
, arr [2]
... if I just let arr
, returns abcdefg
.
I am PHP programmer, and I have a minimal notion with JavaScript, can someone give me a light?
var item = 'abcdefg';
var arr = new Array();
arr[1] = "zzz";
arr[2] = "abc";
var test = item.split(arr);
alert(test.join("\n"));
Use:
var item = 'Hello, 1, my name is 2.';
var arr = new Array();
arr [1] = 'admin';
arr [2] = 'guest';
for (var x in arr)
item = item.replace(x, arr[x]);
alert(item);
It produces:
Hello, admin, my name is guest.
Split uses regular expressions, so
"My String".split('S') == ["My ","tring"]
If you are trying to replace a string:
"abcdef".replace('abc','zzz') == "zzzdef"
