以编程方式在jQuery按钮组中选择无线电使其分解

Question

我正在使用基于单选按钮的jQuery按钮在网站上构建编辑器功能.当我将项目加载到编辑器中时,我需要设置所选的单选按钮,然后,当然,用户可以更改选项并将其保存到数据库中.当项目关闭时,我想将按钮组重置为默认值.

问题是,当我设置按钮组时,它会在我第一次选择每个项目时工作,然后它会崩溃并停止一起工作.

HTML:

<div id="dumpSec">
    <input type="radio" name="security" id="r_public" value="public" class="rSec">
    <label for="r_public"><i class="icon-globe"></i> Public</label>
    <input type="radio" name="security" id="r_private" value="private" class="rSec">
    <label for="r_private"><i class="icon-lock"></i> Private</label>
    <input type="radio" name="security" id="r_link" value="link" class="rSec">
    <label for="r_link"><i class="icon-link"></i> Anyone with the link</label>
</div>
<div>
    If you use the buttons below you can programmatically select each of the radios in the buttonset once before it all breaks down...
</div>
<div>
     <button id="nbr1">Select Private</button><br/>
     <button id="nbr2">Select Link</button><br/>
     <button id="nbr3">Select Public</button><br/>
</div>

JavaScript的:

// Basic function
$("#dumpSec").buttonset();
$("#r_public").attr("checked", true);
$("#dumpSec").buttonset('refresh');

// Put in functions on the demo buttons
$( "#nbr1" )
  .button()
  .click(function( event ) {
    $("#r_private").attr("checked", true);
    $("#dumpSec").buttonset('refresh');
  });

$( "#nbr2" )
  .button()
  .click(function( event ) {
    $("#r_link").attr("checked", true);
    $("#dumpSec").buttonset('refresh');
  });

$( "#nbr3" )
  .button()
  .click(function( event ) {
    $("#r_public").attr("checked", true);
    $("#dumpSec").buttonset('refresh');
  });

我尝试了很多东西,比如试图触发每个单选按钮的标签点击功能等等,但我找不到任何有用的东西.任何输入都表示赞赏!

您需要使用.prop()而不是.attr()来设置检查状态

$("#r_link").prop("checked", true);
