下载OnChange的JAVASCRIPT [英] JAVASCRIPT for Drop Down OnChange

问题描述

我非常喜欢JavaScript。请帮助解决这个问题。


这里的例子是

http://www.javascriptkit.com/script/script2/flipmenu。 shtml

有两个文件夹：JavaScript资源和Web资源。


我希望它们是下拉选项，并根据选择相应的列表应该显示下来，就像我从下拉列表中选择JavaScript一样。

所有的链接，如JavaScript工具包，免费JavaScripts等等都应该被调到下拉列表。


是否有可能。


问候，

Siva

Hi,

I am very much new to JavaScript. Please, can anyone help in resolving this issue.

Here in the example
http://www.javascriptkit.com/script/script2/flipmenu.shtml
There are two folders: JavaScript Resources and Web Resources.

I want them to be options for drop down, and depending on the selection the corresponding lists should b displayed down, like if i select JavaScript from the drop down.
All the links like JavaScript kit, Free JavaScripts...etc should be displed down to the drop down.

Is it possible.

Regards,
Siva

推荐答案

嗨...


据我所知：你想要2个下拉菜单... 1个含2个类别（js，webres）......还有一个取决于选择第一个并显示该类别的不同子项？


您有不同的可能性：创建2个显示/隐藏的选择框（设置样式显示y：none / block）当你从第一个中选择一个值时......或者根据你的选择动态创建选项（用dom-methods）...


亲切的问候

hi ...

as far as i understand: you want 2 dropdowns ... 1 with the 2 categories (js, webres) ... and one that depends on the selection of the first and shows different subitems of the category?

you have different possibilities for that: create 2 select-boxes that are displayed/hidden (set the style display: none/block) when you select a value from the first one ... or dynamically create the options dependent to your selection (with dom-methods) ...

kind regards

谢谢Gits的回复。


我想要第一个下拉肯定，但第二个应该保留在列表结构中，与显示的示例中的相同。我也非常喜欢JavaScript。如果有可能请告诉我。


问候，

Siva

Thanks Gits for ur reply.

I want the first drop down for sure, but the second should remain in the list structure, same as it was in the shown example. Also i am very much new to JavaScript. PLease let me know if it is possible.

Regards,
Siva

当然有可能..简单的方法是：


为列表创建两个div容器并使用我上面提到的set样式方法...在你的选择的更改中你调用一个方法来切换可见性相应的div ...


亲切的问候

of course it is possible ... the simple way is:

create two div-containers for the lists and use the set style method i mentioned above ... onchange of your selection you call a method that toggles the visibilty of the corresponding div ...

kind regards
