Use substring

alert("P-CI-7-C-71".substring(0, 5));

So you can use it like

var str='P-CI-7-C-71'.substring(0, 5);

You can also use substr, that will work the same in this case but remember they work differently so they are not generally interchangeable

var str='P-CI-7-C-71'.substr(0, 5);

Difference can be noticed in the prototype

str.substring(indexStart[, indexEnd])

VS

str.substr(start[, length])

Try this:

alert('P-CI-7-C-71'.substring(0,5));

var str = 'P-CI-7-C-71';
var res = str.slice(0,5);
alert(res);

With String#substring:

The substring() method returns a subset of a string between one index and another, or through the end of the string.

document.write('P-CI-7-C-71'.substring(0, 5));
