问题描述

HI，

我正在应用程序中的Description字段中使用Ajax HtmlEditorExtender.

我的示例代码:

I am using an Ajax HtmlEditorExtender for Description field in my application.

My Sample Code:

<asp:TextBox ID="txtDescription" TextMode="MultiLine" Height="100" CssClass="text" runat="server" />
<ajax:HtmlEditorExtender ID="HtmlEditorExtender2" TargetControlID="txtDescription" runat="server">
       <Toolbar>
            <ajax:Bold />
            <ajax:Italic />
            <ajax:Underline />
            <ajax:HorizontalSeparator />

             <ajax:JustifyLeft />
             <ajax:JustifyCenter />
             <ajax:JustifyRight />
             <ajax:JustifyFull />
             <ajax:HorizontalSeparator />

             <ajax:InsertUnorderedList />
             <ajax:ForeColorSelector />

        </Toolbar>
 </ajax:HtmlEditorExtender>

当我尝试使用空格键并输入密钥时，此说明文本框接受空白. 描述"字段是必填字段，因此不应接受空格.

我无法使用FilteredTextBoxExtender/RequiredFieldValidator/Javascript验证来验证此控件(txtDescription).

This description textbox is accepting empty spaces when i tried with space bar and enter key. The Description field is mandatory and so it should not accept empty spaces.

I am unable to validate this control(txtDescription) using FilteredTextBoxExtender/RequiredFieldValidator/Javascript validation.

Help me out pls!!

推荐答案

function CheckBlankSpace(txtBoxId) 
{
     var tb = document.getElementById(txtBoxId);

     // Trim white space if any before taking value length
     var tbLen = tb.value.trim().length;
     if (tbLen == 0)
     {
        // Raise error or do whatever you like
     }
}

根据需要对其进行修改.

Modify it as per your need.
