改变Recaptcha的主题？

Question

I use the Following script for change recaptcha in asp.net with c# server side.But this code Didn't Work. How to change color or theme of the ReCaptcha?

 <script type="text/javascript">
            var RecaptchaOptions = {theme : 'White'};
       </script>

Answer 1

I think you are just writing the name of the theme in wrong way, just try White with a small 'w'.

<script type="text/javascript">
            var RecaptchaOptions = {theme : 'white'};
</script>

See this link for exact working code:

https://developers.google.com/recaptcha/docs/customization

Answer 2

George Siggouroglou's second method for asp.net is a charm

I couldn't seem to set the theme as instructed in https://developers.google.com/recaptcha/docs/customization - placed the js above the form containing the recaptcha control - but adding the theme attribute directly into the recaptcha code as George explained:

<recaptcha:RecaptchaControl
    ID="recaptcha"
    runat="server"
    PublicKey="your-public-key"
    PrivateKey="your-private-key"
    Theme="white"
/>

works.

Answer 3

U used the capital W instead of small ie w Try this

Change the theme and try

<script type="text/javascript">
 var RecaptchaOptions = {
    theme : 'white'
    /*WE CAN USE FOLLOWING THEME TO CHANGE THE COLOR OF RECAPTHCA*/
    /*red,white,blackglass,clean'*/

    /*lang :'es';*/ //used to set the language
 };
 </script>

Answer 4

If you are using asp.net and if you are using the recapctcha for asp.net control , then if you want to change the theme (red(default),white,blackglass,clean) there is two ways.

Way no1,

To make the reCAPTCHA widget display a different theme, you first need to add the following
code in your main HTML page anywhere before the element where reCAPTCHA appears
(this will not work if placed after the main script where reCAPTCHA is first invoked):

<script type="text/javascript">
    var RecaptchaOptions = {
        theme : 'theme_name'
    };
</script>

Way no2:

Add the property 'Theme' to the recapcha asp.net control:

<recaptcha:RecaptchaControl
    ID="recaptcha"
    runat="server"
    PublicKey="your-public-key"
    PrivateKey="your-private-key"
    Theme="white"
/>
