var weekArray = [];

如何只检查weekArray中的复选框?我尝试的代码是

$('select[name="Day"] option').filter(function(){
         if(weekArray.indexOf((this).text(), 0) != -1);
         return $(this);
    }).prop("checked", true);

但这不起作用。如有任何帮助，不胜感激

你可以这样做，

现场演示

var weekArray = ["saturday","monday","tuesday","friday" ];
$('.weekdays').filter(function () {    
    if (weekArray.indexOf(this.id) != -1)
          return $(this).closest('td').find(':checkbox');
}).prop("checked", true);

您正在使用select选择器为checkbox ????..

 $('#divID input:checkbox').each(function(){
     if($.inArray($(this).val(), weekArray) != -1){
       $(this).prop("checked", true);
    }
});

if(in_array(document.getElementById("CheckBoxId"), $yourArray)) { CheckBox.Checked }

for (var i=0; i<ds.length; i++){
    weekArray = ds[i];
}
$("form input:checkbox").each(function(){
if(jQuery.inArray($(this).attr('id'), weekArray )!=-1)
$(this).prop('checked', true);
});
