Use String#split, Array#map and Array#join methods.
var str = "c:0.1|d:0.2";
console.log(
str
// split string by delimiter `|`
.split('|')
// iterate and generate result string
.map(function(v) {
// split string based on `:`
var s = v.split(':')
// generate the string
return s[0] + ':' + (Number(s[1]) * 100) + "%"
})
// join them back to the format
.join()
)You can also use String#replace method with capturing group regex and a callback function.
var str = "c:0.1|d:0.2";
console.log(
str.replace(/\b([a-z]:)(0\.\d{1,2})(\|?)/gi, function(m, m1, m2, m3) {
return m1 +
(Number(m2) * 100) + // calculate the percentage value
(m3 ? "%," : "%") // based on the captured value put `,`
})
)

It's not angular issue, you can use simple logic, use substring take value after the : and multiply by 100 to get the value as 10 or respective.
