Question

我有多个复选框，并尝试仅检查复选框，但在应用jquery时，我无法访问其范围外的值。这样做的原因是我要传递ajax请求并且没有做任何事情。

我的代码html：

<div name="state" id="state">
<label class="checkbox-inline">
<input type="checkbox" id="offer1" name="offer" value="Monday">Monday
</label>
<label class="checkbox-inline">
<input type="checkbox" id="offer2" name="offer" value="Tuesday">Tuesday
</label>
<label class="checkbox-inline">
<input type="checkbox" id="offer3" name="offer" value="Wednesday">Wednesday
</label>
<label class="checkbox-inline">
<input type="checkbox" id="offer4" name="offer" value="Thursday">Thursday
</label>
<label class="checkbox-inline">
<input type="checkbox" id="offer5" name="offer" value="Friday">Friday
</label>


</div>  
<button name="submit" onclick="continued()" type="submit" class="btn btn-primary btn-block" style="font-size:18px;">Continue</button>

<script>
function continued(){
    var s=$("#school").val();
    var st=$("#student").val();
    var selected = [];
    var sThisVal;
var v =$('#state input:checkbox').each(function (elem) {
 sThisVal = (this.checked ? $(this).val() : "");
//alert(sThisVal);
return sThisVal;

});

alert(v[0]);




}
</script>

Answer 1

netstandard15没有返回类型。您应该在.each()处使用.map()功能：

.get()

Answer 2

function continued() {
  var selected = [];
  $("#state input[type='checkbox']:checked").each(function() {
    selected.push(this.value);
  });
  console.log(selected);
  return selected;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="state">
  <label class="checkbox-inline">
<input type="checkbox" value="Monday">Monday
</label>
  <label class="checkbox-inline">
<input type="checkbox" value="Tuesday">Tuesday
</label>
  <label class="checkbox-inline">
<input type="checkbox" value="Wednesday">Wednesday
</label>
  <label class="checkbox-inline">
<input type="checkbox" value="Thursday">Thursday
</label>
  <label class="checkbox-inline">
<input type="checkbox" value="Friday">Friday
</label>
</div>
<button onclick="continued()">Continue</button>
