+We can import [all locale files](https://github.com/wenzhixin/bootstrap-table/tree/master/src/locale) what you need:
+
+```html
+<script src="bootstrap-table-en-US.js"></script>
+<script src="bootstrap-table-zh-CN.js"></script>
+...
+```
+
+And then use JavaScript to switch locale:
+
+```js
+$.extend($.fn.bootstrapTable.defaults, $.fn.bootstrapTable.locales['en-US']);
+// $.extend($.fn.bootstrapTable.defaults, $.fn.bootstrapTable.locales['zh-CN']);
+// ...
+```
