如何在结帐时添加PayPal折扣代码

Question

只需执行一个简单的代码即可在我的PayPal按钮上应用促销代码。我刚刚在下面做了，但validate（）函数没有警告。

我希望所有代码都正确无误。请检查小提琴，并让我知道为什么功能不起作用。

function validate( text1, text2 ) {

			if ( text1 == text2 ) {
				window.alert( "Nice, you get a 10% Discount!" );
			}
			if ( text1 !== text2 ) {
				window.alert( "Sorry, No Discount!" );
			}
		}

		function CalculateOrder( form ) {

			if ( form.text1.value == "GOLD10" ) {
				form.discount_rate.value = "10";
				form.discount_rate2.value = "10";
				form.on3.value = "Coupon Entered";
				form.os3.value = "GOLD10";
			}
		}

<form target="_self" action="https://www.paypal.com/cgi-bin/webscr" method="post">
		<input type="hidden" name="cmd" value="_cart"/>
		<input type="hidden" name="add" value="1"/>
		<input type="hidden" name="business" value="fanciedmedia@gmail.com"/>
		<input type="hidden" name="item_name" value="Blue Kidsport Burst"/>
		<input type="hidden" name="amount" value="149.00"/>
		<input type="hidden" name="currency_code" value="USD"/>
		<input type="hidden" name="no_shipping" value="2">
		<input type="hidden" name="weight_unit" value="lbs">
		<input type="hidden" name="baseamt" value="149.00"/>
		<input type="hidden" name="item_number" value="BUONBL">
		<span id="dist"></span>

		<input type="text" name="text1">
		<input type="button" value="Check It" name="Submit" onclick=javascript&colon;validate(text1.value, "GOLD10")>
		<br>
		<input name="submit" type="image" alt="Add to Cart" src="add_to.png" onclick=CalculateOrder(this.form)/>

	</form>

您错过了在@Override public Object run() { RequestContext ctx = RequestContext.getCurrentContext(); try { InputStream is = ctx.getResponseDataStream(); String responseBody = IOUtils.toString(is); if (StringUtils.hasText(responseBody) && responseBody.contains("access_token")) { Map<String, Object> responseMap = objectMapper.readValue( responseBody, new TypeReference<Map<String, Object>>() {}); String accesToken = responseMap.get("access_token").toString(); Jwt jwt = JwtHelper.decodeAndVerify(accesToken, new MacSigner(serviceConfig.getJwtSigningKey())); System.out.println(jwt.getClaims()); //System.out.println(jwt.getBody()); } ctx.setResponseBody(responseBody); } catch (Exception e) { logger.error("Error occured in zuul post filter", e); } return null; } 属性中添加简单引号'，您应该引用表单对象以获取onclick值：

text1

应该是：

onclick=javascript:validate(text1.value, "GOLD10")
        ^^                        ^^^                   ^^

onclick=CalculateOrder(this.form)
        ^^                       ^^

试试这段代码：

onclick='javascript:validate(form.text1.value, "GOLD10")'
onclick='CalculateOrder(this.form)'

function validate( text1, text2 ) {

  if ( text1 == text2 ) {
    window.alert( "Nice, you get a 10% Discount!" );
  }
  if ( text1 !== text2 ) {
    window.alert( "Sorry, No Discount!" );
  }
}

function CalculateOrder( form ) {

  if ( form.text1.value == "GOLD10" ) {
    form.discount_rate.value = "10";
    form.discount_rate2.value = "10";
    form.on3.value = "Coupon Entered";
    form.os3.value = "GOLD10";
  }
  
  alert('submitting form');
  form.submit();
}
