问题描述

我必须动态创建一个单选按钮组。我能够成功创建它。但问题是动态创建的单选按钮看起来不像静态按钮。

I have to create a radio button group dynamically.I am able to successfully create it.But the problem is that the dynamically created radio buttons do not look like the static ones.

我尝试了两种方法：
1）在字段集上调用 create - ui-corner-all 类在内部跨度上添加，因此所有单选按钮都显示为圆形。
2）在包含 fieldset 的div上调用创建 - 这里的问题更好。但还是有些存在问题。首先，当只有单选按钮时， ui-controlgroup-last 类被添加到该radiobutton.Next，当添加第二个单选按钮时， ui-controlgroup-last 类被添加到该radiobutton.But ui-controlgroup-last 仍然存在于第一个单选按钮和这个循环重复。因此所有单选按钮都具有最后一个单选按钮的样式。

I tried two approaches:1) Called create on the fieldset - ui-corner-all class is getting added on an inner span and as a result all radio buttons appear rounded.2) Called create on the div that encloses fieldset - Here the problem is better.But still some problems exist.At first,when there is only radio button, ui-controlgroup-last class is getting added to that radiobutton.Next,when the second radio button is added,the ui-controlgroup-last class is getting added to that radiobutton.But the ui-controlgroup-last is still present in the first radio button and this cycle repeats.As a result all radio buttons have the styles of last radiobutton.

这是我的代码：

<!DOCTYPE html>
<html lang="en">
<head>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0rc1/jquery.mobile-1.0rc1.min.css" />
    <script src="http://code.jquery.com/jquery-1.6.4.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.0rc1/jquery.mobile-1.0rc1.min.js"></script>
    <script>
$(document).ready(function()
{
    for (var i = 0; i < 3; i++)
    {
        $("#rgroup1").append('<input type="radio" name="rg1" id="radio1-'+i+'"/><label for="radio1-'+i+'">Value</label>');
        $("#rgroup1").trigger("create");

        $("#rgroup2").append('<input type="radio" name="rg2" id="radio2-'+i+'"/><label for="radio2-'+i+'">Value</label>');
        $("#radiodiv1").trigger("create");

    }
});

    </script>
</head>

<body>
  <div data-role="content">
    <h3>Normal radio buttons</h3>
    <div id="radiodiv">
        <fieldset data-role="controlgroup" id="rgroup">
            <input type="radio" name="rg" id="radio-1"/><label for="radio-1">Value</label>
            <input type="radio" name="rg" id="radio-2"/><label for="radio-2">Value</label>
            <input type="radio" name="rg" id="radio-3"/><label for="radio-3">Value</label>
        </fieldset>
    </div>
    <h3>Dynamically created-Div Refresh</h3>
    <div id="radiodiv">
        <fieldset data-role="controlgroup" id="rgroup1">
        </fieldset>
    </div>
     <h3>Dynamically created-Fieldset Refresh</h3>
    <div id="radiodiv1">
        <fieldset data-role="controlgroup" id="rgroup2">
        </fieldset>
    </div>
  </div>
</body>

PS - 我之所以这样做我在每次追加之后调用create是因为它在我的实际用例中是如何工作的 - 任何时候都只创建一个单选按钮。

P.S - The reason why I am calling create after each append is because thats how it works in my actual usecase-Only one radio button is created at any time.

推荐答案

我通过明确删除<$ c修复了这个问题$ c> ui-controlgroup-last 和 ui-corner-bottom 来自所有标签的类，除了最后一个单选按钮的标签

I fixed this issue by explicitly removing the ui-controlgroup-last and ui-corner-bottom classes from all the labels except the label for the last radio button

<!DOCTYPE html>
<html lang="en">
<head>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0rc1/jquery.mobile-1.0rc1.min.css" />

    <script src="http://code.jquery.com/mobile/1.0rc1/jquery.mobile-1.0rc1.min.js"></script>
    <script>
$(document).ready(function()
{
    for (var i = 0; i < 3; i++)
    {
        /*$("#rgroup1").append('<input type="radio" name="rg1" id="radio1-'+i+'"/><label id="label1-'+i+'" for="radio1-'+i+'">Value</label>');
        $("#rgroup1").trigger("create");*/


        $("#rgroup2").append('<input type="radio" name="rg2" id="radio2-'+i+'"/><label id="label2-'+i+'"for="radio2-'+i+'">Value</label>');
        $("#radiodiv1").trigger("create");


    }
    for (var i = 0; i < 2; i++)
    {
        $('#label2-'+i).removeClass("ui-controlgroup-last ui-corner-bottom");
    }
});

    </script>
</head>

<body>
  <div data-role="content">
    <h3>Normal radio buttons</h3>
    <div id="radiodiv">
        <fieldset data-role="controlgroup" id="rgroup">
            <input type="radio" name="rg" id="radio-1"/><label for="radio-1">Value</label>
            <input type="radio" name="rg" id="radio-2"/><label for="radio-2">Value</label>
            <input type="radio" name="rg" id="radio-3"/><label for="radio-3">Value</label>
        </fieldset>
    </div>
    <!-- <h3>Dynamically created-Div Refresh</h3>
    <div id="radiodiv">
        <fieldset data-role="controlgroup" id="rgroup1">
        </fieldset>
    </div> -->
     <h3>Dynamically created-Fieldset Refresh</h3>
    <div id="radiodiv1">
        <fieldset data-role="controlgroup" id="rgroup2">
        </fieldset>
    </div>
  </div>
