当JavaScript动态添加行时，单选按钮功能无法正常工作

Question

I am fetching values from database via json, and in parallel I am adding radio buttons with 3 options. However, when trying to make a selection I face below issue.

If you run the code and try to select Green for all 3 options, the option keeps jumping from 1 row to another. If you want to select Green for all 3, its not letting it.

My aim is to update the database back with either of 3 options and store the value in json object as status.

My purpose is to make selection out of 3 options and pass it back to database and update. Please help!

 type = "text/javascript" > $(document).ready(function() { var appStatus = [{ "category": "Overall Status", "status": "0" }, { "category": "System Availability", "status": "0" }, { "category": "Whatever 2", "status": "0" }]; var tr; for (var i = 0; i < appStatus.length; i++) { tr = $('<tr/>'); tr.append("<td>" + appStatus[i].category + "</td>"); tr.append('<tr id="row' + i + '"><td><input type="radio" name="inlineRadioOptions []" value="1" checked="checked" id="inlineRadio1"><font color="green">Green &emsp;</font><label class="radio-inline"><input type="radio" name="inlineRadioOptions1 []" id="inlineRadio2" value="YELLOW"><font color="yellow">Yellow &emsp;</font></label><label class="radio-inline"><input type="radio" name="inlineRadioOptions1 []" id="inlineRadio3" value="Red"> <font color="red">Red</font></label><td></tr>'); $('table').append(tr); } }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <table class="table table-hover"><thead> <th>Category</th> <th>Status</th> </thead> </table>

You've just to give them the same name like the following snippet shows.

Then if you want to get the new values, you could loop through the tr's :

var new_status = [];
$('.table tbody tr').each(function(){
   new_status.push( {category: $(this).find('td:eq(0)').text(),status: $(this).find(':radio:checked').val()});
});

Hope this helps.
