JQuery 移动单选按钮在选择其他按钮时保持选中状态。 使用.html function

Question

I can't seem to figure this out, or find any information on this. I'm using the.html() function to generate dynamic HTML to list Camera selection in a radio button format. The code that creates the html is working correctly AFAIK:

var showcameras = function()
{
    var html = "<fieldset data-role='controlgroup' data-type='horizontal'>";
    for (var i = 0; i < sessiondetails["Camera-Count"]; i++)
    {
        var name;
        var namelabel = "Camera-Names_" + i;
        var idlabel = "Camera-ID_" + i;
        if (sessiondetails[namelabel]==="")
            name = "Camera " + (i+1);
        else
            name = sessiondetails[namelabel];
        html += "<input type='radio' name='"+name+"' id='"+sessiondetails[idlabel]+"' value='"+sessiondetails[idlabel]+"'>";
        html += "<label for='"+sessiondetails[idlabel]+"'>"+name+"</label>";
    }
    html += "</fieldset>";
    window.$("#camselection").html(html).trigger("create");
};

This is the HTML it creates:

    <fieldset data-role='controlgroup' data-type='horizontal'>
    <input type='radio' name='test1' id='10000' value='10000'>
    <label for='10000'>test1</label>
    <input type='radio' name='Camera 2' id='10001' value='10001'>
    <label for='10001'>Camera 2</label>
    <input type='radio' name='Camera 3' id='10002' value='10002'>
    <label for='10002'>Camera 3</label>
    <input type='radio' name='Camera 4' id='10003' value='10003'>
    <label for='10003'>Camera 4</label>
    </fieldset>

This is the HTML for the "camselection" div tag:

    <div id="camselection" data-role="fieldcontain"></div>

Here's the problem, I can select more than one radio button at a time. Doesn't make sense to me since they are in the same fieldset. I've even tried putting onClick('refresh') on each button, but it doesn't work. Any help is greatly appreciated

Answer 1

In order to select only one radio button they must have the same name.

<fieldset data-role='controlgroup' data-type='horizontal'>
  <input type='radio' name='camera' id='c10000' value='10000'>
  <label for='c10000'>test1</label>
  <input type='radio' name='camera' id='c10001' value='10001'>
  <label for='c10001'>Camera 2</label>
  <input type='radio' name='camera' id='c10002' value='10002'>
  <label for='c10002'>Camera 3</label>
  <input type='radio' name='camera' id='c10003' value='10003'>
  <label for='c10003'>Camera 4</label>
</fieldset>

BTW it is better when id attribute is starting with a letter.

The radio button grouping is defined by the name attribute. Your buttons all have different names, so they are part of different groups.

It should be something like this:

<fieldset data-role='controlgroup' data-type='horizontal'>
<input type='radio' name='camera' id='10000' value='10000'>
<label for='10000'>test1</label>
<input type='radio' name='camera' id='10001' value='10001'>
<label for='10001'>Camera 2</label>
<input type='radio' name='camera' id='10002' value='10002'>
<label for='10002'>Camera 3</label>
<input type='radio' name='camera' id='10003' value='10003'>
<label for='10003'>Camera 4</label>
</fieldset>

Try giving the radio buttons the same name. Then you'll be able to select only one radio button.
