jQuery Magnific Popup无法正常工作-js-newbie

Question

what am I doing wrong? this is the easiest variation from magnific popup, but I just can't get this running for hours. I'm a newbie to JS, but other things worked out pretty well?!

i used the JS-File from here https://raw.github.com/dimsemenov/Magnific-Popup/master/dist/jquery.magnific-popup.min.js from that stackoverflow post: Magnific-popup doesn't work at all

 @charset "utf-8"; /* CSS Document */ #some-button, #some-button2 {padding:20px} .white-popup { position: relative; background: black; padding: 40px; width: 2000px; max-width: 2000px; margin: 20px auto;

thanks for your help!

Answer 1

Try wrapping it in a function

$(function () {
$('#some-button').magnificPopup({
items: [
  {
    src: 'pic.jpg'
  },
  {
    src: 'http://vimeo.com/123123',
    type: 'iframe' // this overrides default type
  },
  {
    src: $('<div>Dynamically created element</div>'), // Dynamically created element
    type: 'inline'
  },
  {
    src: '<div>HTML string</div>',
    type: 'inline'
  },
  {
    src: '#my-popup', // CSS selector of an element on page that should be used as a popup
    type: 'inline'
  }
],
gallery: {
  enabled: true
},
type: 'image' // this is default type
});
});

Answer 3

Everyone here's correct, I just want to make it clear.

You are trying to act on an element that has not loaded. Both Jquery and the actual DOM elements you're manipulating won't have loaded by the time your 3rd party JS is executed.

Without JQuery, your included script is gibberish to the browser and unless the DOM is ready, the JS will simply return an error. Include your Jquery before the 3rd party plugin.

Do this by either including your script in an external file at the bottom AFTER the Jquery include, or shift Jquery up above the include. Then wrap your actual function in a 'onready' function:

As mvargos points out, you can wrap the JS in a

$(function(){}). 

This is JQuery short hand for

$(document).ready(function(){});

Document.ready means only run after the DOM has loaded and all your elements actually exist for the JS to act on.
