I was surprised to find out that Javascript didn't come with such a function.
It's pretty easy to monkey patch though, it doesn't even need jQuery!
if (typeof String.prototype.startsWith != 'function') {
String.prototype.startsWith = function (input){
return this.substring(0, input.length) === input
};
} After that you can just use it like any other string function.
var hash = "#someAnchor";
if (hash.startsWith('#img_')) {
$('a[href="' + hash + '"]').trigger('click');
}
Now we've trained Javascript well!
