javascript - if javascript 中 .datepicker 属性的条件

Question

我有一个日期选择器，我想要 defaultDate 属性，如果它满足我的条件。这是下面的代码，

 $(function () {
                jQuery('#datepicker').datepicker({
                  <% if (parseInt(location.search.indexOf('did=')) >= 0) { %>
                        defaultDate: getDefaultDateVal(),
                   <% } %>
                   //     defaultDate: parseInt(location.search.indexOf('did=')) >= 0 ? getDefaultDateVal() : new Date(),
                        inline: true,
                        maxDate: '+10D',
                        onLoad:function(){alert("hello");},
                        onSelect: function(date) {
                            //alert('Diet plan for ' + date);
                        var d = new Date("January 01, 1970 00:00:00");
                        var d2 = new Date(date);
                        d.setMonth(d.getMonth());
                        var theMonth;
                        theMonth = d.toString();
                        theMonth = theMonth.substr(4, 3);

                        d2.setMonth(d2.getMonth());
                        var theMonth2;
                        theMonth2 = d2.toString();
                        theMonth2 = theMonth2.substr(4, 3);

                        var firstDay = d.getDate();
                        var secondDay = d2.getDate();
                        var firstMonth = theMonth;
                        var secondMonth = theMonth2;
                        var firstYear = d.getFullYear();
                        var secondYear = d2.getFullYear();
                        var firstDate = new Date(firstDay + " " + firstMonth + " " + firstYear);
                        var secondDate = new Date(secondDay + " " + secondMonth + " " + secondYear);
                        var daysDiff = (secondDate.valueOf() - firstDate.valueOf());
                        daysDiff = Math.floor(Math.abs((((daysDiff / 1000) / 60) / 60) / 24));
                        //alert(daysDiff);


                        self.location.href = './Goal.aspx?did=' + daysDiff + '';
                        //filterGetMidHead(date);
                        //wait(500);

                        //   alert(date);
                        var startdate = ((d2.getDate()).toString().length == 1) ? "0" + (d2.getDate()).toString() : (d2.getDate()).toString();
                        var enddate = new Date();
                        enddate.setDate(d2.getDate() + 7);
                        var enddate1 = ((enddate.getDate()).toString().length == 1) ? "0" + (enddate.getDate()).toString() : (enddate.getDate()).toString();
                        //  alert(enddate1 + "hello");
                        var month2 = ((d2.getMonth() + 1).toString().length == 1) ? "0" + (d2.getMonth() + 1).toString() : (d2.getMonth() + 1).toString();
                        var endatemonth = ((enddate.getMonth() + 1).toString().length == 1) ? "0" + (enddate.getMonth() + 1).toString() : (enddate.getMonth() + 1).toString();

                        //alert(new Date().setDate(d2.getDate() + 7));
                        document.getElementById('<%=lblHeaderDate1.ClientID %>').innerHTML = startdate + "/" + month2 + "/" + d2.getFullYear();
                        document.getElementById('<%=lblHeaderDate2.ClientID %>').innerHTML = enddate1 + "/" + endatemonth + "/" + enddate.getFullYear();
                        //    testnew();
                    }
                });

                  <% if (Convert.ToString(Session["LanguageID"])=="IS") 
                       { %>
                    jQuery("#datepicker").datepicker(jQuery.datepicker.regional['is']);
                    <% } %>

                //jQuery("#datepicker").datepicker(jQuery.datepicker.regional['is']);


                //hover states on the static widgets
                jQuery('#dialog_link, ul#icons li').hover(
                        function () { jQuery(this).addClass('ui-state-hover'); },
                        function () { jQuery(this).removeClass('ui-state-hover'); }
                    );
            });

但是它向我显示错误。任何人都可以帮助我如何编写 if 条件来设置 datepicker attribue$("defaultDate: parseInt(location.search.indexOf('did=')) >= 0 ? getDefaultDateVal() : new Date(),").datepicker?

Answer 1

你想做什么？

<% if (parseInt(location.search.indexOf('did=')) >= 0) { %>
                    defaultDate: getDefaultDateVal(),
<% } %>

parseInt显示 javascript 但 <%显示 asp 的服务器端代码块

为什么不只在服务器端做呢？试试这个

<% if (System.Web.HttpContext.Current.Request.QueryString.ToString().Contains("did=")) { %>
                    defaultDate: getDefaultDateVal(),
<% } %>
