I am getting a response from a SOAP server and it is an array of bytes, fixed size.
For instance, I get { rsp: { errorNumber: '1', errorMessage: { item: [Object] } } }
[ '73',
'110',
'118',
'97',
'108',
'105',
'100',
'32',
'112',
'97',
'115',
'115',
'119',
'111',
'114',
'100',
'0']
How do I turn that array to a string it javascript?
Each "byte" in your array is actually the ASCII code for a character. String.fromCharCode will convert each code into a character.
It actually supports an infinite number of parameters, so you can just do:
String.fromCharCode.apply(String, arr);
When ran on your array you get: "Invalid password".
As @Ted Hopp points out, the 0 at the end is going to add a null character to the string. To remove it, just do: .replace(/\0/g,'').
String.fromCharCode.apply(String, arr).replace(/\0/g,'');
"Invalid password". So, I figured my assumption was ok :-)
Here's one more alternative using map:
var str = arr.map(String.fromCharCode).join("");
Here is what you want, the String.fromCharCode function:
var foo = [
'73',
'110',
'118',
'97',
'108',
'105',
'100',
'32',
'112',
'97',
'115',
'115',
'119',
'111',
'114',
'100',
'0'];
var str = '';
for (var i=0; i<foo.length; ++i) {
str+= String.fromCharCode(foo[i]);
}
console.log(str);
Or better :
var str = String.fromCharCode.apply(null, foo);
console.log([ '73', '110', '118', '97', '108', '105', '100', '32', '112', '97', '115', '115', '119', '111', '114', '100', '0'].toString());String.fromCharCode.apply(String,arr);
