[Solved] Javascript – What’s faster: a linear list search or getting an object value? [closed]

by

[ad_1] An object lookup will on average be much faster when trying to find a random element, especially when you are searching through a large number of items.

[Solved] Trigger a Facebook like button when the page loads [closed]

by

[ad_1] You can’t. Clicking on the <fb:like> element has no effect because it’s just a container. The actual clickable “like” button is loaded in an <iframe> inside of it. Because this iframe is loaded from facebook.com, the same origin policy prevents you from accessing its contents (including the link you want) unless you are also … Read more

[Solved] One variable returns two seperate array

by

[ad_1] Since the two request aren’t linked in any way and are asynchronous, you have to group the data manually once both files have been read. I usually use util.promisify() to turn fs.readFile() from accepting a callback into it returning a promise, so I can use Promise.all() to create the array once both files have … Read more

[Solved] Why am I getting Uncaught Error: Syntax error, unrecognized expression in my JavaScript? [closed]

by

[ad_1] You should pass the nonce parameter with a valid nonce, when the server side code is called. For example, assuming you’ve implemented your code into JavaScript file that you are including using the function wp_enqueue_script wp_enqueue_script( ‘my_js_file’, ‘http://www.yourwebsitedomain.com/your_js_file.js’); As the nonce must be generated in the server side you should call the wp_localize_script function … Read more
