Dynamically load javascript files

Question

var _scriptUrl = [
    'vendor/jquery/jquery-1.9.1.min.js',
    'vendor/angular/angular.js',
    'vendor/angular/angular-cookies.js',
    'vendor/bootstrap/js/bootstrap.min.js',
    'vendor/bootstrap/js/bootstrap-datepicker.js'
]

var jsElm = document.createElement("script");
jsElm.type = "application/javascript";

for(var i = 0; i < _scriptUrl.length; i++)
{
    jsElm.src = _scriptUrl[i];
    document.body.appendChild(jsElm);
}

But it is always appending last one only, please suggest.

Answer 1

Try appending the child in the loop. In your example, you only have one instance of script.

for(var i = 0; i<_scriptUrl.length; i++)
{
    var jsElm = document.createElement("script");
    jsElm.type = "application/javascript";
    jsElm.src = _scriptUrl[i];
    document.body.appendChild(jsElm);
}

If you're serious about async loading of js, try requirejs.
