JQuery 不适用于 Joomla 3 [英] JQuery not working on Joomla 3

问题描述

我正在尝试在 Joomla 3 下制作一个简单的 jQuery 脚本.这是我的模块现在的样子:

I am trying to make a simple jQuery script work under Joomla 3. Here is what my module looks now:

<?php 
// no direct access
defined('_JEXEC') or die;

$doc = JFactory::getDocument();
JHtml::_('jquery.framework');
$doc->addScriptDeclaration('
    $(document).ready(function () {
       $(".text").text("By this");
    });
');
?>

<div class="text">Text should be changed...</div>

我在普通页面上尝试了此代码段并且运行良好，只是我不知道为什么它不想在 Joomla 中运行.我也安装了 jQuery Easy 插件，但没有成功.

I tried this snippet on a normal page and works perfectly, just I don't know why it does not want to work in Joomla. I installed the jQuery Easy plugin as well, but with no success.

推荐答案

好的，经过大量研究我终于有了答案.因为 Joomla 默认通过 namespacing 处理 jQuery，所以你必须把它放在你的 jQuery 代码中.这里也提到:http://docs.joomla.org/J3.1:Javascript_Frameworks#jQuery_JavaScript_Framework

Ok, finally after a lot of research I have the answer. Because the Joomla is handling jQuery through namespacing by default, you have to put it in your jQuery code. It mentions here as well: http://docs.joomla.org/J3.1:Javascript_Frameworks#jQuery_JavaScript_Framework

因此，您必须使用 jQuery 而不是使用 $.所以这是工作代码:

So instead of using $ you have to use jQuery. So here is the working code:

<?php 
// no direct access
defined('_JEXEC') or die;

$doc = JFactory::getDocument();
JHtml::_('jquery.framework');

$doc->addScriptDeclaration('
    jQuery(document).ready(function () {
        jQuery(".text").text("By this :)");
    });     
');
?>

<div class="text">Text should be changed...</div> 

我希望它有帮助:)

P.S:您可以通过像这样更改 jQuery 声明来关闭命名空间

P.S: You can turn the namespacing off by changing the jQuery declaration like so

JHtml::_('jquery.framework', false);

请注意，这对我不起作用...

Please note that this wasn't working for me...
