HTML下拉选择值 [英] HTML Dropdown selection value

问题描述

我有以下代码：

I have the following code:

<select>
<option value="blablabla">Test</option>
<!-- ... -->
</select>

但是我想知道是否可以将option标签的value属性设置为引用一个对象（在JavaScript中）。

But I want to know if I can set the "value" attribute of the option tag, as a reference to an object (in javascript).

推荐答案

选项值必须是字符串可以是一个数字）。

The option value must be a "string" (that string can be a number).

你想做的事情有点不寻常，但可以完成（但我认为有更好的方法来实现你想做的事情） ...你可以序列化你的对象并将其设置为值，但这将是奇怪的。

What you want to do is a bit unusual but can be done (but I think there are better ways to achieve what you want to do)... You could serialize your object and set it in the value but that would be odd.

您也可以将这些引用索引到数组中，然后将其索引设置为该选项的价值......

You could also index these references in an array and then set it's index in the value of the option...
