您好，我正在尝试刷新我的页面，然后在刷新完成后运行一个函数。但是，我现在拥有的代码运行了函数，然后它只会刷新，这意味着我失去了该函数的作用。有办法解决吗？

function reloadP(){

You need to call myFunction()when the page is loaded.
您需要myFunction()在页面加载时调用。
window.onload = myFunction;
If you only want to run it when the page is reloaded, not when it's loaded for the first time, you could use sessionStorageto pass this information.
如果您只想在页面重新加载时运行它，而不是在第一次加载时运行，则可以使用sessionStorage传递此信息。
window.onload = function() {
var reloading = sessionStorage.getItem("reloading");
if (reloading) {
sessionStorage.removeItem("reloading");
myFunction();
}
}
function reloadP() {
sessionStorage.setItem("reloading", "true");
document.location.reload();
}

function myFunction() {
document.getElementById("welcome").textContent = "Welcome back!";
}
window.onload = function() {
var reloading = sessionStorage.getItem("reloading");
if (reloading) {
sessionStorage.removeItem("reloading");
myFunction();
}
}
function reloadP() {
sessionStorage.setItem("reloading", "true");
document.location.reload();
}
