正则表达式（javascript）提取以某个常量字符串开头的字符串

Question

I am trying to extract a string which is preceded by some constant string, the example is as follows.

string ="deleteabc@bcd" 
match should be "abc@bcd"
or
string = "deletebcd@def"
match should be "bcd@def"

so as you can see i want to extract anything after the constant string "delete", please help, thanks in advance

Answer 1

If you just want to remove a prefix

function removePrefix(str, prefix) {
    if (str.search(prefix) === 0) {
        return str.substr(prefix.length);
    } else {
        return str;
    }
}

Answer 2

string = "deleteabc@bcd"
result = string.match(/^delete(.+)/)
console.log(result[1])

abc@bcd
