jQuery在选择单选按钮时更改输入文本 [英] jQuery Change Input text upon selection of radio button
本文介绍了jQuery在选择单选按钮时更改输入文本的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
尝试获取<input class="box" type="text" value="??" name="searchQuery"的值="，以在选择单选按钮时进行更改.因此，例如，如果用户按下名字"单选按钮，它会将.box输入的值更改为诸如输入名字"之类的值，并且也将其用于其他单选按钮.
Trying to get the value="" of <input class="box" type="text" value="??" name="searchQuery" to change upon selection of a radio button. So if the user presses 'first name' radio button for example, it changes the value of .box input to a value such as "Enter a first name" and have it do it for the other radio buttons as well.
