Hexadecimal to string in javascript
javascript
Solution
From your comments it appears you're calling
hex2a('000000000000000000000000000000314d464737');
and alerting the result.
Your problem is that you're building a string beginning with 0x00. This code is generally used as a string terminator for a null-terminated string.
Remove the `00` at start :
hex2a('314d464737');
You might fix your function like this to skip those null "character" :
function hex2a(hex) {
var str = '';
for (var i = 0; i < hex.length; i += 2) {
var v = parseInt(hex.substr(i, 2), 16);
if (v) str += String.fromCharCode(v);
}
return str;
}
Note that your string full of 0x00 still might be used in other contexts but Chrome can't alert it. You shouldn't use this kind of strings.
Problem
``` function hex2a(hex) { var str = ''; for (var i = 0; i < hex.length; i += 2) str += String.fromCharCode(parseInt(hex.substr(i, 2), 16)); return str; } ``` This function is not working in chrome, but it is working fine in mozila. can anyone please help. Thanks in advance
