一个ajax日历控件如何具有多个文本框? [英] how to have multiple textbox for a ajax calendar control?

问题描述

我有这个ajax日历控件，但是我单击btnDate3，它将添加文本框的另一行，这使我可以再次从日历控件中选择日期，因此，如果我单击提交"，它将从每个文本框中检索每个文本框日期添加后排
因此基本上用户可以单击添加"按钮，它将添加另一行具有相同功能的文本框

i have this ajax calendar control, but i click on the btnDate3 it will add another row of the textbox which allow me to select date from the calendar control again, so if i click submit, it will retrieve each textbox date from each row after you Add
so basically a user can click on the Add button then , it will add another row of textbox which have the same function

<asp:TextBox runat="server" ID="txtDate1" />
            <ajaxtoolkit:calendarextender  runat="server" ID="calExtender1" 

                                        TargetControlID="txtDate1" OnClientDateSelectionChanged="CheckDateEalier" Format="dd/MM/yyyy"/>
 <asp:Button ID="btnDate3" Text="Add" Width="20px" runat="server" />
 <asp:Button ID="submit" Text="Submit" Width="20px" runat="server" />

这是我用来检查日期的JavaScript

this is the javascript i use to check the date

<script type="text/javascript">
    function CheckDateEalier(sender,args) {
        if (sender._selectedDate < new Date()) {
             alert("You cannot select a day before today or today!");
             sender._selectedDate = new Date(); 
             // set the date back to the today
            // sender._textbox.set_Value(sender._selectedDate.format(sender._format))
             sender._textbox.set_Value(null)
         }
     }
</script>

推荐答案

store previous date values in to a string using a <b>separator "&" and append</b> all new string values to the old string.

<b>split</b> the string with the character "&" and store it into an array of string.

<b>Get the count</b> of array and <b>create dynamic textbox controls</b> with respect to the count of the contents of the array.

include the above logic into your onclick code.
