I am learning JS and very new to coding.
function querySelection(e){
console.log(document.querySelector(e));
}
querySelection('h5');
querySelection('#id');
querySelection('.className');
//querySelection('li: last child');
The very last query throws an error (commented). I am very new JS.I am not sure what is wrong in that query?
Change
querySelection('li: last child');
to
querySelection('li:last-child')

I am hooking up flexslider into a custom Wordpress theme but running into an issue within my JS which is strange.
jQuery(document).ready(function)($) {
$('.flexslider').flexslider();
});
It is telling me there is an unexpected token of ) but I can't see the offending part of script?
You've mixed up your parentheses:
jQuery(document).ready(function)($) {
$('.flexslider').flexslider();
});
should be:
jQuery(document).ready(function($) {
$('.flexslider').flexslider();
});

I am getting an unexpected token error when in my console when I run the page. Can anyone help point out where this is coming from? I believe I'm going blind because I can't see it.
define('QuoteSetupPageController', 'jquery' {
this.init = function() {
$(document).click(function(){
$('.header-message-indicator').hide();
});
}
});
Error is on line 1.
Thank you.
It should be:
define('QuoteSetupPageController', 'jquery', {
You were missing a comma.
