修改我的单选按钮的文本? [英] Modify the text of my radio input button?

问题描述

您的平均单选按钮具有名称和值，并且旁边还有一些文本，在这种情况下为更改此文本".

Your average radio button has a name and value, but also some text next to it, in this case "Change this text."

如何在javascript中对此进行更改?甚至警惕吗? AFAIK，它不是.inner html.

How can I change this in javascript? Or even alert it? AFAIK, it is NOT the .inner html.

HTML:

            <input type="radio" name="radioOption1" value="Array 1"> Change this text

JavaScript

Javascript

    var confirmIExist = document.getElementsByName("radioOption1");
alert(confirmIExist.innerHTML);
    //alerts undefined

如果不是.innerHTML，那是什么?如果我使用getElementByName或getElementById来抓取输入对象，那之后的哪一部分代表警报文本?

If it's not .innerHTML, what is it? if I grab the input object with either getElementByName or getElementById, what chunk after that represents the Alert text?

推荐答案

您不能为输入元素设置内部html.而是用a包裹您的文本并为其指定ID

You cannot set inner html for a input element. instead wrap your text with a and give it a ID

<input type="radio" name="radioOption1" value="Array 1"> <label id="radioText">Change this text</label>
