Question

我有一个网页，其中有一个检查按钮，如果选择了一个按钮，然后它会显示一个警报，如果有两个，那么它应该显示两个警报，但它只显示一个首先选择的按钮。

我正在使用以下代码

$(document).ready(function(){
    $("#email_multiple").click(function(){
        var n = $("input:checked").length;
        //alert(n);
        //for(var i=1;i<=$("input:checked").length;i++){alert(n);}
        if(!($("input:checked").length)){
            alert('Please make a check on check box field thanks hahahahha...');
            return false;
        }
        if(n==1){
            var bb = $("input:checked").val();
            alert(bb);
            presenter.command("emailSend",{
                "toEmail": "",
                "toName": "",
                "subject": "",
                "body": "Single Attachment",
                "bodyHtml":"",
                 "attachments": ["/images/Animal/pdf/"+bb+".pdf"]
            }); 
            $('input[type=checkbox]').attr('checked',false);
        }
        if(n==2){
            var bb = $("input:checked").val();
            alert(bb);
            presenter.command("emailSend",{
                "toEmail": "",
                "toName": "",
                "subject": "",
                "body": "Single Attachment",
                "bodyHtml":"",
                 "attachments": ["/images/Animal/pdf/"+bb+".pdf","/images/Animal/pdf/"+bb+".pdf"]
            }); 
            $('input[type=checkbox]').attr('checked',false);
        }
    });
});
