不允许空格的Java脚本验证.

问题描述

我需要验证文本框，而不能在起始位置留空格，并且两个单词之间只能留一个空格..

1234567
例如:Vino Pr --->正确:第5个位置是空格，即只允许一个位置.

123456789
例如:Vino Pr --->此示例在第1位置允许的空间不正确，并且在
之间允许2个空格..我需要在文本框中获取输入，不允许在第1个位置使用空格，并且在单词之间不允许使用多个空格.

我使用了Text.StartTrim().EndTrim()

从文本框添加到gridview时它正确显示.
但是从Gridview到数据库，它允许有空格.

Hi huys i need to validate the textbox without allowing space starting position and allowing only one space between two words..

1234567
Ex:Vino Pr--->correct: 5th position is space i.e only one position is allowed.

123456789
Ex: Vino Pr--->This Example is incorrect 1st Position allowed Space and in between
allowed 2 spaces.. i need to textbox to get input not allowing the space in the 1st position and not allow the more than one space between the words.

i used the the Text.StartTrim().EndTrim()

it coming correctly while adding in the gridview from textbox.
But from Gridview to database it allowing the spaces.

推荐答案

<script type="text/javascript">

    function AllowSingleSpaceNotInFirstAndLast() {
        var obj = document.getElementById('TextBox1');
        obj.value = obj.value.replace(/^\s+|\s+

Username: <input type="text" id="TextBox1" name="user" />
<input type="button" value="Submit" onclick="return AllowSingleSpaceNotInFirstAndLast();" />

<div>
   <script type=""text/javascript">

language="javascript">
       function isNumberKey(evt) {
           //    if (!(((event.keyCode >= 48 && event.keyCode <= 57) || (event.keyCode >= 96 && event.keyCode <= 105)) || (event.keyCode == 8) || (event.keyCode == 9) || (event.keyCode == 37) || (event.keyCode == 39) || (event.keyCode == 46) || (event.keyCode == 190) || (event.keyCode == 35) || (event.keyCode == 36)))

           //event.returnValue=false;

           var charCode = (evt.which) ? evt.which : event.keyCode

           if (charCode > 31 && charCode < 48 || charCode > 57)
               if (event.keyCode != 46)
                   if (event.keyCode != 110)

                       return false;

           return true;



       }


</script>
close the script tag

<asp:textbox id="txtAdm" runat="server" onkeypress="return isNumberKey(event)" xmlns:asp="#unknown">
                      Width="150px" MaxLength="8"></asp:textbox>

       </div>
