如何创建 onClick javascript 事件以将其重定向到另一个网站？

Question

我有一个使用 GTranslate 的 WordPress 网站。当我制作中文版网站时，我希望当有人点击 GTranslate 下拉菜单中的“中文”时，我实际上将他发送到新的中文网站。 GTranslate 插件开发人员告诉我，我需要为此创建 Javascript onclick 事件。请问我该怎么做？

当有人在 GTranslate 的下拉列表中选择此选项时：

简体中文）

我需要将它们发送到一个新的 URL。 你能告诉我 Javascript 以及如何实现它 - 在哪里放置脚本吗？

Answer 1

在这里，我在

<select>

和一个数组

languages

中提供了一个稍微更全面的大选项列表。

您的插件可能在选择列表中具有类似的值，但未提供该参考，因此我给出了这个通用答案。

当列表中的语言与选项匹配并且语言

isActive

为true时，我们向选项添加一个活动类并通过CSS显示它；有效地隐藏列表中所有非活动的。

您可以修改 JavaScript

languages

数组来激活您现在在站点上创建的任何内容 - 这甚至可以在某种程度上通用地完成。

现在您所要做的就是激活语言并输入正确的 URL（或者根据您的

url

值构建 URL 的函数，这是我的建议。

Answer 2

将

onclick="newPageFunction(url)"

添加到下拉列表中的中文按钮，然后尝试此功能

function newPageFunction(url) {
window.open(url);
}

您应该在 url 变量中调整新页面的 url
