我必须为需要网络工作者的学校做项目,该项目是关于必须在后台计算的质数,但是我具有计算质数的功能,但我不知道如何正确使用它(网络工作者)与主要功能,我也得到一些错误:

script.js:

if(typeof(w) == "undefined") {
w = new Worker("prvocisla.js");
}
w.onmessage = function(event) {
document.getElementById("result").innerHTML = event.data;
};
} else {
document.getElementById("result").innerHTML = "Web workery nie su dostupne!";
}
}
function stopWorker() {
w.terminate();
w = undefined;
}
prvocisla.js:
function jePrvocislo(cislo){
var i = 2;
while(i < cislo){
if(cislo % i == 0){
return false;
}
i++;
}
return true;
}
function najdiPrvocislo(cislo){
var i = 0;
while(i < cislo){
if(jePrvocislo(i)){
console.log(i);
}
i++;
}
}
najdiPrvocislo(50000);
错误: Errors
引起错误的行:
w = new Worker("prvocisla.js");
<button onclick="startWorker()">Start Worker</button>
