Yes, It's possible. Try this.
Script.js
function loadJSAtOnload() {
var scripts = [
"/Scripts/Angular.js",
"/Scripts/jquery-1.9.1.js",
"/Scripts/bootstrap.min.js",
];
for (var i = 0; i < scripts.length; i++) {
console.log('Loading script ' + scripts[i]);
var scriptType = document.createElement('script');
scriptType.type = 'text/javascript';
scriptType.src = scripts[i];
document.body.appendChild(scriptType);
}
};
if (window.addEventListener)
addEventListener('load', loadJSAtOnload, false);
else if (window.attachEvent)
window.attachEvent('onload', loadJSAtOnload);
else window.onload = loadJSAtOnload;
