JS:通过getElementsByClassName使某些元素隐藏

问题描述

我正在尝试建立一个脚本，该脚本使用特定的类名将所有内容设置为不可见.这是我要呼叫的示例:

I'm trying to set up a script that sets invisible everything with a certain class name.This is an example of what I'm trying to call:

<script type="text/javascript">
function hideItems(){
        document.getElementsByClassName('class1').style.visibility = "hidden";
}
</script>

类名在表的维度上，类似于此示例:

The class names are on the dimensions of a table, similar to this example:

<table onclick="hideItems()" width="200" border="1">
  <tr>
    <td class="class1">1</td>
    <td class="class2">2</td>
    <td class="class3">3</td>
    <td class="class1">1</td>
    <td class="class2">2</td>
    <td class="class3">3</td>
  </tr>
  <tr>
    <td class="class3">3</td>
    <td class="class1">1</td>
    <td class="class2">2</td>
    <td class="class3">3</td>
    <td class="class1">1</td>
    <td class="class2">2</td>
  </tr>
</table>

最后，将有三个复选框，根据选择的三个维度显示尺寸.那部分我可以做得很好，但是调用特定的尺寸以使其不可见是我目前遇到的问题.

In the end, there's going to be a three checkboxes, displaying the dimensions based on which of the three are selected. That part, I can do just fine, but calling the particular dimensions to become invisible is what I'm having an issue with currently.

在此先感谢您的帮助.

推荐答案

getElementsByClassName返回一个集合.除非您使用jquery

getElementsByClassName returns a collection. You can't collectively set properties unless you're using a framwork like jquery

var elems = document.getElementsByClassName('class1');

for(var i = 0; i != elems.length; ++i)
{
elems[i].style.visibility = "hidden"; // hidden has to be a string
}
