如何使用jquery ???

检查单选按钮是否已选中

这是代码：

     function handlesClick(myRadio) {
        debugger
       var selectedmerchant = [];
        if (myRadio != '') {
            var myRadios = $('input[name=myRadio]');
            //var checkedValue = $("#myRadio").attr('checked', 'checked');
            //if ($('#myRadio').is(':checked')) { alert("it's checked"); }
            //$('input[type="radio"][class="icheck-list"]:checked').val()
            if ($("#myRadio").is(":checked") === true)
            {
                selectedmerchant.push(myradio);
                selectedmerchant.join(",");
            }
            else
            {
 var index = selectedmerchant.indexof(merchant);
               selectedmerchant.splice(index, 1);
            }
     //if (document.getelementbyid(myradio).checked == true) {
            //    selectedmerchant.push(myradio);
            //    selectedmerchant.join(",");
            //}
            //else {
            //    var index = selectedmerchant.indexof(merchant);
            //    selectedmerchant.splice(index, 1);
            //}

我想检查是否选中了复选框，以便我可以使用javascript推送或切片数组。 任何代码???

这是html：

  <div class="row">
    <div class="form-group">
      <div class="col-md-12">
        <label>3.sdfdsfsdfds</label>
        <div class="icheck-list">
          <label class="icheck-list" id="11">

            <input name="3" onclick="handlesClick(this);" id="3_11" type="radio">Strongly Disagree
            <span></span>
          </label>
        </div>
        <div class="icheck-list">
          <label class="icheck-list" id="12">
            <input name="3" onclick="handlesClick(this);" id="3_12" type="radio">Disagree
            <span></span>

            <span></span>
          </label>

Answer 1

检查一下，

＆＃13;

＆＃13;

window.selectedmerchant = {};
function handlesClick(myRadio) {
  if ($(myRadio).is(":checked")) {
   window.selectedmerchant[$(myRadio).attr("name")] = $(myRadio).attr("id");
  }
  console.log(window.selectedmerchant);
}

我只采用了三个示例作为演示，但检查代码，它现在工作正常。

我希望这会有所帮助。

Answer 2

为此，请尝试以下代码：

<input name="3" onclick="handlesClick(this);" id="3_1" type="radio">Agree

<input name="3" onclick="handlesClick(this);" id="3_2" type="radio">Disagree

//这是JS代码//

function handlesClick(RadioId) {

if (RadioId != '') {
if ($(RadioId).is(":checked") === true) 
    {

  //Add condition for checked Radio

     } 
 else 
    {

   //Add condition for unchecked Radio

    }
  }
}
