paypal button issue with contact_form

since i am using the plug in my paypal button do not work anymore.

Here are details about the issue on stackoverflow:

Ok, so i tried something. I must admit that I am totally new to js and dont know if the following solution is bulletproof but both my PayPal button and the contactform are working now. Here is what i have done:

I went through the jqBootstrapValidation.js file and incrementally disabled parts of it until I found the spot that made my PayPal button work again. I found out that if line 49 of the js file:

var $inputs = $form.find("input,textarea,select").not("[type=submit],[type=image]").filter(settings.options.filter);

is disabled, the PayPal button works fine.

So next I wrapped the var into an if statement looking like this:

if (
     $form.hasClass("contactform")
   ) {
     var $inputs = $form.find("input,textarea,select").not("[type=submit],[type=image]").filter(settings.options.filter);
      }

so basically now the class "contactform" is needed in the html file to set the var $inputs.

My Contactform HTML looks like this now:

<div class="col-sm-offset-3 col-lg-6">
    <form name="sentMessage" id="contactForm" class="contactform" novalidate>
        <legend class="content-legend">Kontakt</legend>
        <div class="control-group">
            <div class="controls">
                <input type="text" class="form-control content-form" placeholder="Name" id="name" required data-validation-required-message="Bitte geben sie Ihren Namen ein" />
            </div>
        </div>
        <div class="control-group">
            <div class="controls">
                <input type="email" class="form-control content-form" placeholder="Mail" id="email" required data-validation-required-message="Bitte geben Sie eine Mailadresse ein" />

[...] etc.

e.g. the form contains the class "contactform".

My PayPal Button HTML looks like this:

<form target="_blank" action="https://www.paypal.com/cgi-bin/webscr" method="post" id="paypalbutton" target="_top" style="float:right;">
    <input type="hidden" name="cmd" value="_s-xclick">
    <input type="hidden" name="hosted_button_id" value="xxx">
    <input type="submit" value="Jetzt zahlungspflichtig Bestellen" border="0" name="submit" title="Jetzt einfach, schnell und sicher online bezahlen – mit PayPal." class="btn btn-primary">
    <img alt="" border="0" src="https://www.paypalobjects.com/de_DE/i/scr/pixel.gif" width="1" height="1">
</form>

e.g. the form does not contain the class "contactform". The var $inputs will not be set by the jqBootstrapValidation.js file and so it does not trigger what ever prevents the PayPal button from working.

I hope it helps.
