jquery Magnific Popup赢了工作 - js-newbie

Question

我做错了什么？这是来自大型弹出窗口的最简单的变化，但我不能让它运行数小时。我是JS的新手，但是其他的东西效果还不错？！

我在这里使用了JS-File https://raw.github.com/dimsemenov/Magnific-Popup/master/dist/jquery.magnific-popup.min.js 来自stackoverflow帖子：Magnific-popup doesn't work at all

Answer 1

尝试将其包装在函数中

$(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
});
});

$(document).ready(function() {

Answer 3

这里的每个人都是正确的，我只想说清楚。

您正在尝试对未加载的元素执行操作。在你的第三方JS执行时，Jquery和你正在操作的实际DOM元素都不会被加载。

如果没有JQuery，你所包含的脚本对浏览器来说是乱七八糟的，除非DOM准备就绪，否则JS只会返回一个错误。 在第三方插件之前包含您的Jquery。

通过将脚本包含在Jquery包含的底部的外部文件中，或者将Jquery转移到include之上来执行此操作。然后将您的实际函数包装在'onready'函数中：

正如mvargos指出的那样，你可以将JS包装在

中

$(function(){}). 

这是

的JQuery简写

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

Document.ready表示只在DOM加载后运行，并且所有元素实际存在供JS执行。
