How can I get bootstrap version via javascript?
提问by Selman Gen?
Is there any way to get bootstrapversion via calling a function? I did some research but couldn't find any way, the version information is included in the comments at the beginning like this:
有没有办法bootstrap通过调用函数来获取版本？我做了一些研究但找不到任何方法，版本信息包含在开头的评论中，如下所示：
/*!
* Bootstrap v3.3.7 (http://getbootstrap.com)
* Copyright 2011-2016 Twitter, Inc.
* Licensed under the MIT license
*/
/*!
* Bootstrap v3.3.7 (http://getbootstrap.com)
* Copyright 2011-2016 Twitter, Inc.
* Licensed under the MIT license
*/
But in case the comments are removed how do I get the bootstrap version? Bootstrap plugins have a version defined in them but I'm looking for the general bootstrap version, not version of a particular plugin.
但如果评论被删除，我该如何获得引导程序版本？Bootstrap 插件中定义了一个版本，但我正在寻找通用的引导程序版本，而不是特定插件的版本。

The version of each of Bootstrap's jQuery plugins can be accessed via the VERSION property of the plugin's constructor. For example, for the tooltip plugin:
可以通过插件构造函数的 VERSION 属性访问每个 Bootstrap jQuery 插件的版本。例如，对于工具提示插件：
$.fn.tooltip.Constructor.VERSION // => "3.3.7"
src //getbootstrap.com/javascript/#js-version-nums
src //getbootstrap.com/javascript/#js-version-nums
if you mean from the css, then yu ahve to AJAX the file and .match(/v[.\d]+[.\d]/);
如果你的意思是从 css 中，那么你 ahve 到 AJAX 文件和 .match(/v[.\d]+[.\d]/);

You can use this code found here:
您可以使用此处找到的代码：
var getBootstrapVersion = function () {
var deferred = $.Deferred();
var script = $('script[src*="bootstrap"]');
if (script.length == 0) {
return deferred.reject();
}
var src = script.attr('src');
$.get(src).done(function(response) {
var matches = response.match(/(?!v)([.\d]+[.\d])/);
if (matches && matches.length > 0) {
version = matches[0];
deferred.resolve(version);
}
});
return deferred;
};
getBootstrapVersion().done(function(version) {
console.log(version); // '3.3.4'
});

This spinoff of the Constructor method adds a fallback plugin and returns an array:
这个 Constructor 方法的衍生添加了一个回退插件并返回一个数组：
var version = ($().modal||$().tab).Constructor.VERSION.split('.');
You can access the major revision with version[0], of course.
version[0]当然，您可以使用 访问主要修订版。
