隐藏多个具有相同名称或类的标签 [英] Hiding multiple tag with same name or class

问题描述

我使用的是原型 1.5.你能告诉我，我如何隐藏/显示具有相同名称或类的 div 标签.

I have using prototype 1.5. Can you please tell me, how can i hide/show the div tag with same name or class.

Element.hide('indicate')

但是，上面这行只满足隐藏第一个元素.指示"是ID.

But, the above line only satisfy to hide the first element only. "indicate" is the id.

推荐答案

正如所指出的，$$ 函数是必需的.它返回一个数组，因此您需要invoke隐藏所有项目.>

As pointed out, the $$ function is required. It returns an array so you need to invoke hide on all items.

$$('.indicate').invoke('hide');

或者，为了获得额外的炫耀点数，您可以直接将该函数用作对象:

Or, for bonus showing off points, you can use the function directly as an object:

var hideFunc = Element.hide;
$$('.indicate').each(hideFunc);

这种技术的优势意味着您可以轻松地将功能替换为另一个功能，例如 一个 Scriptaculous效果.

The advantage of this technique means you can easily swap the function for another, such as a Scriptaculous effect.

hideFunc = Effect.SwitchOff;
