如何使用jquery设置单选按钮选择的值

Question

How to set radio button selected value in javascript :

HTML Code :

<input type="radio" name="RBLExperienceApplicable" class="radio" value="1" > 
<input type="radio" name="RBLExperienceApplicable" class="radio" value="0" >


<input type="radio" name="RBLExperienceApplicable2" class="radio" value="1" > 
<input type="radio" name="RBLExperienceApplicable2" class="radio" value="0" >

ASPX Code

     <asp:RadioButtonList ID="RBLExperienceApplicable" runat="server" class="radio"    RepeatDirection="Horizontal" EnableViewState="false">
            <asp:ListItem Value="1" Text="Yes &nbsp;&nbsp;"></asp:ListItem> 
                <asp:ListItem Value="0" Text="No"></asp:ListItem>
        </asp:RadioButtonList>

     <asp:RadioButtonList ID="RBLExperienceApplicable2" runat="server" class="radio"  RepeatDirection="Horizontal" EnableViewState="false">
            <asp:ListItem Value="1" Text="Yes &nbsp;&nbsp;"></asp:ListItem> 
                <asp:ListItem Value="0" Text="No"></asp:ListItem>
        </asp:RadioButtonList>

// Some Code Fetch from db
// Based on db value script block will execute

 <script type="text/javascript">
        RadionButtonSelectedValueSet('1');
 </script>

Script Block :

function RadionButtonSelectedValueSet(SelectdValue) {
    $('#RBLExperienceApplicable').val(SelectdValue);
        //$("input[name='RBLExperienceApplicable']:checked").val(SelectdValue);
}

Answer 1

Try

function RadionButtonSelectedValueSet(name, SelectdValue) {
    $('input[name="' + name+ '"][value="' + SelectdValue + '"]').prop('checked', true);
}

also call the method on dom ready

<script type="text/javascript">
jQuery(function(){
    RadionButtonSelectedValueSet('RBLExperienceApplicable', '1');
})
</script>

Answer 2

You can do more elegantly.

function RadionButtonSelectedValueSet(name, SelectedValue) {
    $('input[name="' + name+ '"]').val([SelectedValue]);
}

Answer 3

You can try this also

function SetRadiobuttonValue(selectedValue)
{
  $(':radio[value="' + selectedValue + '"]').attr('checked', 'checked');
}

Answer 4

Below script works fine in all browser:

function RadionButtonSelectedValueSet(name, SelectdValue) {
     $('input[name="' + name + '"][value="' + SelectdValue + '"]').attr('checked',true);
}

Answer 5

$('input[name="RBLExperienceApplicable"]').prop('checked',true);

多谢，伙计...

Answer 6

If the selection changes, make sure to clear the other checks first. al la...

 $('input[name="' + value.id + '"]').attr('checked', false); $('input[name="' + value.id + '"][value="' + thing[value.prop] + '"]').attr('checked', true); 

Answer 7

for multiple dropdowns

$('[id^=RBLExperienceApplicable][value='+ SelectedVAlue +']').attr("checked","checked");

here RBLExperienceApplicable is the matching part of the radio button groups input tag ids. and [id^=RBLExperienceApplicable] matches all the radio button whose id start with RBLExperienceApplicable

Answer 8

  <input type="radio" name="RBLExperienceApplicable" class="radio" value="1" checked > 
 //       For Example it is checked
 <input type="radio" name="RBLExperienceApplicable" class="radio" value="0" >


<input type="radio" name="RBLExperienceApplicable2" class="radio" value="1" > 
<input type="radio" name="RBLExperienceApplicable2" class="radio" value="0" >


      $( "input[type='radio']" ).change(function() //on change radio buttons
   {


    alert('Test');
   if($('input[name=RBLExperienceApplicable]:checked').val() != '') //Testing value
 {

$('input[name=RBLExperienceApplicable]:checked').val('Your value Without Quotes');

}
    });

Answer 9

  <asp:RadioButtonList ID="rblRequestType">
        <asp:ListItem Selected="True" Value="value1">Value1</asp:ListItem>
        <asp:ListItem Value="Value2">Value2</asp:ListItem>
  </asp:RadioButtonList>

You can set checked like this.

var radio0 = $("#rblRequestType_0");
var radio1 = $("#rblRequestType_1");

radio0.checked = true;
radio1.checked = true;

Answer 10

我发现一个干净的方法是为每个单选按钮提供一个ID ，然后使用以下语句进行设置：

document.getElementById('publicedit').checked = true;

Answer 11

Can be done using the id of the element

example

<label><input type="radio" name="travel_mode"  value="Flight" id="Flight"> Flight </label>
<label><input type="radio" name="travel_mode"  value="Train" id="Train"> Train </label>
<label><input type="radio" name="travel_mode"  value="Bus" id="Bus"> Bus </label>
<label><input type="radio" name="travel_mode"  value="Road" id="Road"> Other </label>

js:

$('#' + selected).prop('checked',true);

Answer 12

这是唯一对我有用的语法

$('input[name="assReq"][value="' + obj["AssociationReq"] + '"]').prop('checked', 'checked');

Answer 13

document.getElementById("TestToggleRadioButtonList").rows[0].cells[0].childNodes[0].checked = true;

其中TestToggleRadioButtonList是RadioButtonList的id。
