我正在通过正则表达式在焦点输出上验证 javascript 中的一些 .net 文本框:
ValidationExpression="[0-9]+(\.[0-9][0-9]?)?"
对于所有文本框。
如果 isValidate,按钮启用 = true 否则按钮启用 = false
但我的代码不起作用:
<dx:ASPxTextBox ID="tbxAcPart" runat="server" Width="95px" ClientIDMode="Static">
<ClientSideEvents Validation="function(s, e) {ValidTextBox(s);}" />
<ValidationSettings ErrorDisplayMode="Text" EnableCustomValidation="true" SetFocusOnError="true" ValidationGroup="Apply" Display="Dynamic" ErrorTextPosition="Bottom" >
<ErrorFrameStyle Font-Size="Smaller"/>
<RegularExpression ValidationExpression="[0-9]+(\.[0-9][0-9]?)?" ErrorText="Numeric !" />
<RequiredField IsRequired="true" />
</ValidationSettings>
</dx:ASPxTextBox>
<dx:ASPxTextBox ID="tbxMpPart" runat="server" Width="95px" ClientIDMode="Static">
<ClientSideEvents Validation="function(s, e) {ValidTextBox(s);}" />
<ValidationSettings ErrorDisplayMode="Text" EnableCustomValidation="true" SetFocusOnError="true" ValidationGroup="Apply" Display="Dynamic" ErrorTextPosition="Bottom" >
<ErrorFrameStyle Font-Size="Smaller"/>
<RegularExpression ValidationExpression="[0-9]+(\.[0-9][0-9]?)?" ErrorText="Numeric !" />
<RequiredField IsRequired="true" />
</ValidationSettings>
</dx:ASPxTextBox>
function ValidTextBox(s) {
if (s.GetIsValid()) {
decimalErr.SetText('');
}
else {
decimalErr.SetText(s.GetErrorText());
var t = document.getElementsById("btApply");
t.disabled = true;
this.focus();
}
}
