我有一些代码,我正在为客户端编写,他们目前正在使用Drupal 6和jQuery 1.3.2 - 我无法控制他们使用的jQuery,所以我试图编写一些基于的代码假设它不会很快改变。我一直在重新编写代码,现在它的工作时间早在1.4,但我已经碰到了一个砖墙,试图让它在1.3上工作。
我正在使用FlatUI的单选按钮 - 这里的原始按钮(https://raw.github.com/designmodo/Flat-UI/master/js/flatui-radio.js) - 我已经重新使用了它,但找不到阻止它触发的内容。
我已经设置了一个JSFiddle来演示我的问题。除了年龄选择部分之外,一切都工作正常,每个年龄的左边都应该有复选框(13 +,14 +等)。正如我所说,它可以追溯到1.4,甚至可以查看jQuery文档,我找不到任何其他不适用于1.3的内容。
以下是无效的代码:

如果您要将现有代码转换为以前的版本,只是因为您的某些插件需要在旧版本上运行。我建议你不要这样做。
您可以在同一页面上使用不同的版本,因此无需更新现有代码:
<!-- load jQuery version 1.9.0 -->
<script src="jquery-1.9.0.js" type="text/javascript"></script>
<script type="text/javascript">
var $jQuery1_9 = $.noConflict(true);// Here you must need to pass true
//else it will only free $ variable
//and using jQuery with blow libraries
//cause conflict
</script>
//you must load second library later after initializing
//first instance of version and freeup jQuery keyword
//else jQuery keyword will
//cause conflict it you uplaoded both files.
<!-- load jQuery version 1.10.0 -->
<script src="jquery-1.10.0.js" type="text/javascript"></script>
<script type="text/javascript">
var $jQuery1_10 = $.noConflict(true);
</script>
//so now here $ and jQuery both cannot be used
//using $jQuery1_10 will call version 1.10.0 library code
$jQuery1_10( "div p" ).show();
//using $jQuery1_9 will call version 1.9.0 library code
$jQuery1_9( "div p" ).show();
