Question

I have this code to produce a date/time picker but I only need to use the date picker element of this code.

我将如何从这一法典中删除时间选择要素,并且是否发挥作用?

function show_calendar(str_target, str_datetime) {
var arr_months = ["January", "February", "March", "April", "May", "June",
    "July", "August", "September", "October", "November", "December"];
var week_days = ["Su", "Mo", "Tu", "We", "Th", "Fr", "Sa"];
var n_weekstart = 1; // day week starts from (normally 0 or 1)

var dt_datetime = (str_datetime == null || str_datetime =="" ?  new Date() : str2dt(str_datetime));
var dt_prev_month = new Date(dt_datetime);
dt_prev_month.setMonth(dt_datetime.getMonth()-1);
var dt_next_month = new Date(dt_datetime);
dt_next_month.setMonth(dt_datetime.getMonth()+1);
var dt_firstday = new Date(dt_datetime);
dt_firstday.setDate(1);
dt_firstday.setDate(1-(7+dt_firstday.getDay()-n_weekstart)%7);
var dt_lastday = new Date(dt_next_month);
dt_lastday.setDate(0);

var str_buffer = new String (
    "<html>
"+
    "<head>
"+
    "   <title>Calendar</title>
"+
    "</head>
"+
    "<body bgcolor="White">
"+
    "<table class="clsOTable" cellspacing="0" border="0" width="100%">
"+
    "<tr><td bgcolor="#4682B4">
"+
    "<table cellspacing="1" cellpadding="3" border="0" width="100%">
"+
    "<tr>
 <td bgcolor="#4682B4"><a href="javascript:window.opener.show_calendar( "+
    str_target+" ,  "+ dt2dtstr(dt_prev_month)+" +document.cal.time.value);">"+
    "<img src="prev.gif" width="16" height="16" border="0""+
    " alt="previous month"></a></td>
"+
    "   <td bgcolor="#4682B4" colspan="5">"+
    "<font color="white" face="tahoma, verdana" size="2">"
    +arr_months[dt_datetime.getMonth()]+" "+dt_datetime.getFullYear()+"</font></td>
"+
    "   <td bgcolor="#4682B4" align="right"><a href="javascript:window.opener.show_calendar( "
    +str_target+" ,  "+dt2dtstr(dt_next_month)+" +document.cal.time.value);">"+
    "<img src="next.gif" width="16" height="16" border="0""+
    " alt="next month"></a></td>
</tr>
"
);

var dt_current_day = new Date(dt_firstday);

str_buffer += "<tr>
";
for (var n=0; n<7; n++)
    str_buffer += " <td bgcolor="#87CEFA">"+
    "<font color="white" face="tahoma, verdana" size="2">"+
    week_days[(n_weekstart+n)%7]+"</font></td>
";

str_buffer += "</tr>
";
while (dt_current_day.getMonth() == dt_datetime.getMonth() ||
    dt_current_day.getMonth() == dt_firstday.getMonth()) {

    str_buffer += "<tr>
";
    for (var n_current_wday=0; n_current_wday<7; n_current_wday++) {
            if (dt_current_day.getDate() == dt_datetime.getDate() &&
                dt_current_day.getMonth() == dt_datetime.getMonth())

                str_buffer += " <td bgcolor="#FFB6C1" align="right">";
            else if (dt_current_day.getDay() == 0 || dt_current_day.getDay() == 6)

                str_buffer += " <td bgcolor="#DBEAF5" align="right">";
            else

                str_buffer += " <td bgcolor="white" align="right">";

            if (dt_current_day.getMonth() == dt_datetime.getMonth())

                str_buffer += "<a href="javascript:window.opener."+str_target+
                ".value= "+dt2dtstr(dt_current_day)+" +document.cal.time.value; window.close();">"+
                "<font color="black" face="tahoma, verdana" size="2">";
            else 

                str_buffer += "<a href="javascript:window.opener."+str_target+
                ".value= "+dt2dtstr(dt_current_day)+" +document.cal.time.value; window.close();">"+
                "<font color="gray" face="tahoma, verdana" size="2">";
            str_buffer += dt_current_day.getDate()+"</font></a></td>
";
            dt_current_day.setDate(dt_current_day.getDate()+1);
    }

    str_buffer += "</tr>
";
}

This section bilds the forms but when I remover the time element out of the form it doesn t work properly? The date picker will appear but won t close after I remover the time picker element! How do I fix this?

str_buffer +=
    "<form name="cal">
<tr><td colspan="7" bgcolor="#87CEFA">"+
    "<font color="White" face="tahoma, verdana" size="2">"+
    "Time: <input type="text" name="time" value=""+dt2tmstr(dt_datetime)+
    "" size="8" maxlength="8"></font></td></tr>
</form>
" +
    "</table>
" +
    "</tr>
</td>
</table>
" +
    "</body>
" +
    "</html>
";

var vWinCal = window.open("", "Calendar", 
    "width=200,height=250,status=no,resizable=yes,top=200,left=200");
vWinCal.opener = self;
var calc_doc = vWinCal.document;
calc_doc.write (str_buffer);
calc_doc.close();
}


    function str2dt (str_datetime) {     
var re_date = /^(d+)-(d+)-(d+)s+(d+):(d+):(d+)$/;
if (!re_date.exec(str_datetime))
    return alert("Invalid Datetime format: "+ str_datetime);
return (new Date (RegExp.$3, RegExp.$2-1, RegExp.$1, RegExp.$4, RegExp.$5,    RegExp.$6));
}
function dt2dtstr (dt_datetime) {
return (new String (
    dt_datetime.getFullYear()+"/"+(dt_datetime.getMonth()+1)+"/"+dt_datetime.getDate()));
 }
 function dt2tmstr (dt_datetime) {
return (new String (
dt_datetime.getHours()+":"+dt_datetime.getMinutes()+":"+dt_datetime.getSeconds()));
 }

但是,这部法典是可怕的。最好是完全改写。我建议:

至少与数据和逻辑分开列报。最简单(虽然相当粗略)的方法是把所有(有针对性) html留在一起。不要 app/bu。获取必要数据含有异构元素,并操纵这些因素,即:
```
var $layout = $( <form> +
                     <div/>  +
                     ....
                 </form> ),
    $dateInput = $layout.find( input[name="date"] );

.....

$dateInput.val(date);
```
;
更好地利用现有数据方法
