我有一个正在修改Shopify应用程序的脚本（这意味着脚本是通过第三方进程附加的，但我无法访问它们。）我希望仅在脚本完全完成执行后才能加载脚本，但是我无法弄清楚用什么来表示此过程已完成。
这是我的脚本（当前使用setInterval作为权宜之计）：
$(window).load(function(){
var check = setInterval(function() {
let sprCheck = window['SPR'];
var spr = $("#shopify-product-reviews"),
container = spr.find(".spr-content"),
reviewButton = spr.find(".spr-summary-actions-newreview");
if (sprCheck) {
clearInterval(check);
var reviews = spr.find('.spr-reviews'),
reviewButtonWrap = spr.find('.spr-summary-actions'),
form = spr.find('.spr-form'),
toggleContainer = spr.find('.spr-summary-actions-togglereviews'),
reviewButtonLabel = reviewButton.text();
reviewButtonWrap.detach().appendTo(container);
spr.css('overflow','visible');
form.detach().insertAfter(reviews);
if (reviews.children().length) {
reviewButtonWrap.css('display', 'none');
}
toggleContainer.click(function() {
reviewButtonWrap.toggle();
});
spr.fadeTo(300, 1);
reviewButton.click(function(){
if (form.is(':visible')) {
reviewButton.text('Cancel Review');
reviewButton.addClass('spr-close-form');
} else {
reviewButton.text(reviewButtonLabel);
reviewButton.removeClass('spr-close-form');
}
});
}
}, 300);
})
这是他们的脚本的附加位置：
(function() {
function asyncLoad() {
var urls = ["\/\/productreviews.shopifycdn.com\/assets\/v4\/spr.js?shop=sukker-sweet-phase-2.myshopify.com"];
for (var i = 0; i < urls.length; i++) {
var s = document.createElement('script');
s.type = 'text/javascript';
s.async = true;
s.src = urls[i];
var x = document.getElementsByTagName('script')[0];
x.parentNode.insertBefore(s, x);
}
};
if(window.attachEvent) {
window.attachEvent('onload', asyncLoad);
} else {
window.addEventListener('load', asyncLoad, false);
}
})();
这是他们的脚本本身：
e = function() {
"use strict";
window.innerShiv = function() {
function n(e, t, r) {
return /^(?:area|br|col|embed|hr|img|input|link|meta|param)$/i.test(r) ? e : t + "></" + r + ">"
}
var s, o = document,
d = "abbr article aside audio canvas datalist details figcaption figure footer header hgroup mark meter nav output progress section summary time video".split(" ");
return function(e, t) {
if (!s && ((s = o.createElement("div")).innerHTML = "<nav></nav>", 1 !== s.childNodes.length)) {
for (var r = o.createDocumentFragment(), a = d.length; a--;) r.createElement(d[a]);
r.appendChild(s)
}
if (e = e.replace(/^\s\s*/, "").replace(/\s\s*$/, "").replace(/<script\b[^<]*(?:(?!<\/script>)<[^<]*)*<\/script>/gi, "").replace(/(<([\w:]+)[^>]*?)\/>/g, n), s.innerHTML = (r = e.match(/^<(tbody|tr|td|col|colgroup|thead|tfoot)/i)) ? "<table>" + e + "</table>" : e, r = r ? s.getElementsByTagName(r[1])[0].parentNode : s, !1 === t) return r.childNodes;
a = o.createDocumentFragment();

附加了他们的脚本的位置，您可以尝试添加onload属性：
var s = document.createElement('script');
s.type = 'text/javascript';
s.async = true;
s.onload = "functionToRunMyOwnScript()"
我认为您有2个选择。
