你好先生hw ru！

i希望通过点击一个按钮替换radiobutton text permenentaly dynamicaly。

例如我想改变从中取出的radiobutton文本textfield然后当我重新启动项目时，对radiobutton的更改不存在。



所以请给出简单的例子，用代码替换radiobutton文本或作为整体radiobutton由另一个单击按钮即可完成单选按钮。

解决方案

您应该将文本包装在<   label  > 元素：
 
 <   div     id   =  TheOptions >  
 <  输入   类型  =  radio    id   =  test1    name   =  mylist  /  >  <   label     for   =  test1 > 选项1 <   / label  >  
 <   input     type   =  radio     id   =  test2    name   =  mylist  /  >  <   label       =  test1 > 选项2 <   / label  >  
 <  输入    type   = < span class =code-keyword> radio    id   =  test3   姓名  =  mylist  /  >  <   label  < span class =code-attribute>   for   =  test1 > 选项3 <   / label  >  
 <  输入    type   =  radio    id   =  test4    name   =  mylist  /  >  <   label     for   =  test1 > 选项4 &   / label  >  
 <   / div  >  
 <  输入   类型  = 按钮    id   =  btnChnage  /  >  
 
现在，您的文字与相应的单选按钮明确关联，用户将即使能够点击文字，视障用户也会非常感谢提高可用性。然后你可以这样做：

（document）.ready（function（）{

（'＃btnChange'）。click（function（） {

解决方案

You should wrap your text in <label> elements:

<div id="TheOptions">
  <input type="radio" id="test1" name="mylist"/><label for="test1">option 1</label>
  <input type="radio" id="test2" name="mylist"/><label for="test1">option 2</label>
  <input type="radio" id="test3" name="mylist"/><label for="test1">option 3</label>
  <input type="radio" id="test4" name="mylist"/><label for="test1">option 4</label>
</div>
<input type="button" id="btnChnage"/>

Now your text is explicitly associated with the corresponding radio button and users will even be able to click on the text, visually impaired users will also be quite thankful for the improved usability. Then you can just do:

(document).ready(function(){

('#btnChange').click(function(){
