bootstrap toggle doesn't work after ajax load
提问by Michvw
i'm using ajax load to get some content on my page. I'm working with bootstrap 3 and bootstrap toggle. when the content is loaded the bootstrap 3 content works fine (you can clearly see the panel panel-primary). But the bootstrap toggle content doesn't get loaded (you can just see some checkboxes). Does annyone know how to get this working? Or should i look out to some other toggle switches? Ifso which ones?
我正在使用 ajax 加载在我的页面上获取一些内容。我正在使用引导程序 3 和引导程序切换。加载内容后，bootstrap 3 内容工作正常（您可以清楚地看到面板 panel-primary）。但是引导程序切换内容不会加载（您只能看到一些复选框）。annyone 知道如何让这个工作吗？或者我应该注意其他一些拨动开关？如果是哪些？
EDIT: i haven't tested out event binding yet because i cant get the bootstrap toggle css to work on the ajax loaded code. Event binding has nothing to do with the css right?
编辑：我还没有测试事件绑定，因为我无法让引导程序切换 css 处理 ajax 加载的代码。事件绑定与 css 无关吧？
- Scripts used by the main html code (the one with ajax load)
- Main html code
- code being loaded into a div by the main html code
- 主要 html 代码使用的脚本（带有 ajax 加载的代码）
- 主要的html代码
- 代码被主 html 代码加载到 div 中

Make sure that you are loading both the bootstrap-toggle js file and css file properly. Specifically check that they are in the location your links point to, or even use the cdn versions listed below:
确保正确加载了 bootstrap-toggle js 文件和 css 文件。特别检查它们是否在您的链接指向的位置，或者甚至使用下面列出的 CDN 版本：
<link href="https://gitcdn.github.io/bootstrap-toggle/2.2.0/css/bootstrap-toggle.min.css" rel="stylesheet">
<script src="https://gitcdn.github.io/bootstrap-toggle/2.2.0/js/bootstrap-toggle.min.js"></script>
Your paths must be wrong or you forgot to include the js file altogether, and you should see a warning about this in your console because otherwise the code works fine.
您的路径一定是错误的，或者您忘记完全包含 js 文件，您应该在控制台中看到有关此的警告，否则代码可以正常工作。
Regarding dynamically loaded content.
关于动态加载的内容。
The first elements work because, after the html first loads, bootstrap-toggle.min.jslooks for any elements that have the attribute data-toggle="toggle"and calls .bootstrapToggle()on them applying the plugin. This only happens when the page loads.
第一个元素起作用，因为在 html 首次加载后，bootstrap-toggle.min.js查找具有该属性的任何元素data-toggle="toggle"并.bootstrapToggle()应用插件调用它们。这仅在页面加载时发生。
If you later add more toggles, you'll need to initialize them yourself via .bootstrapToggle(). Iv'e updated the example below to simulate adding toggles dynamically and explain the approach I would take to do that. See the comments in the code for more details.
如果您稍后添加更多切换，则需要通过.bootstrapToggle(). 我更新了下面的示例以模拟动态添加切换并解释我将采取的方法。有关更多详细信息，请参阅代码中的注释。
// timeout to simulate ajax
setTimeout(function(){
// add an element dynamically,
$('.table').append('<tr><td>Testswitch0</td><td><label><input type="checkbox" data-toggle="toggle" data-onstyle="success" id="S2" data-size="mini"></label></td></tr>');
// now that we have dynamically loaded elements
// we need to initialize any toggles that were added
// you shouldn't re-initialize any toggles already present
// but we also do want to have to figure out how to find the ones we added
// instead, we'll destroy all toggles and recreate all new ones
$("[data-toggle='toggle']").bootstrapToggle('destroy')
$("[data-toggle='toggle']").bootstrapToggle();
}, 2000)

The best solution that worked:
有效的最佳解决方案：
1- Load Jquery before bootstrap. Here Jquery first, Ajax second and bootstrap in the end.
1- 在引导之前加载 Jquery。这里首先是 Jquery，其次是 Ajax，最后是引导程序。
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" integrity="sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/gh/gitbrent/[email protected]/js/bootstrap4-toggle.min.js"></script>
2- Call bootstrapToggle on ajax complete:
2- 在 ajax 上调用 bootstrapToggle 完成：
$(document).ajaxComplete(function() {
$('input[type=checkbox][data-toggle^=toggle]').bootstrapToggle();
});
3- Note: Call your custom script jquery at the end
3- 注意：最后调用您的自定义脚本 jquery
