Question

我在多个div中有以下复选框。

<div class="div1">
    <input type="checkbox" class="chkbox" value="101"> This is 101
    <input type="checkbox" class="chkbox" value="102"> This is 102
    <input type="checkbox" class="chkbox" value="103"> This is 103
</div>
<div class="div2">
    <input type="checkbox" class="chkbox" value="110"> This is 110
    <input type="checkbox" class="chkbox" value="102"> This is 102
    <input type="checkbox" class="chkbox" value="101"> This is 101
</div>

如上所示，一些复选框在多个div中具有相同的值（例如，101）。现在，每当选中复选框时，我都需要检查具有相同值的其他复选框。同样，取消选中。

$(".chkbox").change(function() {
    // If checked
    if (this.checked)
           // find other checkboxes with same value and check them
    else
           // find other checkboxes with same value and uncheck them
}

Answer 1

你可以这样做：

$(".chkbox").change(function() {
    var val = $(this).val();
  if( $(this).is(":checked") ) {

    $(":checkbox[value='"+val+"']").attr("checked", true);
  }
    else {
        $(":checkbox[value='"+val+"']").attr("checked", false);
    }
});

$(".chkbox").change(function() {
    // If checked
    if (this.checked)
           $(":checkbox[value=" + this.value + "]").attr('checked', true);
    else
           $(":checkbox[value=" + this.value + "]").attr('checked', false);           // find other checkboxes with same value and uncheck them
})

您错过了更改事件的结束时间)。

Answer 4

$( ".chkbox" ).change(function() {
  var value = $( this ).attr( "value" );

  $( ".chkbox[value='" + value + "']" ).prop( "checked", this.checked );
});

Answer 5

// if user has already sent the survey
    if(user_id_value){

        var result = confirm("This user already received a survey. Are you sure you want to resend?");

        // do not send the survey again
        if(!result){            
            $(":checkbox[value='"+user_id+"']").attr("checked", false);         
        }// end if not confirmed

    }// end if

根据值选中或取消选中具有相同类名的所有复选框
