javascript - 从 HTML 页面中的第三方响应数据中获取单个值

Question

我需要有关如何从 HTML 页面获取单个值的帮助。我在 HTML 页面中收到了一些 PAYU 支付网关团队的回复，但我需要来自追踪交易的个别属性值

以下是 PAYU 团队的回复:

<h1>This is the success url</h1>
<p>Your transaction is completed successfully. Bank response is 
   mihpayid=403993715514374636&amp;mode=&amp;status=failure&amp;unmappedstatus=userCancelled&amp;key=gtKFFx&amp;txnid=txn1r23fw&amp;amount=100.00&amp;discount=0.00&amp;net_amount_debit=0.00&amp;addedon=2016-04-25+10%3A48%3A29&amp;productinfo=oxygenconcentrator&amp;firstname=test&amp;lastname=&amp;address1=&amp;address2=&amp;city=&amp;state=&amp;country=&amp;zipcode=&amp;email=test%40gmail.com&amp;phone=8152709721&amp;udf1=&amp;udf2=&amp;udf3=&amp;udf4=&amp;udf5=&amp;udf6=&amp;udf7=&amp;udf8=&amp;udf9=&amp;udf10=&amp;hash=6a9d21bd423d61cd5a7d91098aa1140314e45eaddd8d4b9148399caba8ac61a9476aec130eb369f7d526e741b1b6c47b1ca71bec21fa69aa3deaa13740dbffbc&amp;field1=&amp;field2=&amp;field3=&amp;field4=&amp;field5=&amp;field6=&amp;field7=&amp;field8=&amp;field9=Cancelled+by+user&amp;payment_source=payu&amp;PG_TYPE=&amp;bank_ref_num=&amp;bankcode=&amp;error=&amp;error_Message=

PayU.onSuccess("mihpayid=403993715514374636&amp;mode=&amp;status=failure&amp;unmappedstatus=userCancelled&amp;key=gtKFFx&amp;txnid=txn1r23fw&amp;amount=100.00&amp;discount=0.00&amp;net_amount_debit=0.00&amp;addedon=2016-04-25+10%3A48%3A29&amp;productinfo=oxygenconcentrator&amp;firstname=test&amp;lastname=&amp;address1=&amp;address2=&amp;city=&amp;state=&amp;country=&amp;zipcode=&amp;email=test%40gmail.com&amp;phone=8152709721&amp;udf1=&amp;udf2=&amp;udf3=&amp;udf4=&amp;udf5=&amp;udf6=&amp;udf7=&amp;udf8=&amp;udf9=&amp;udf10=&amp;hash=6a9d21bd423d61cd5a7d91098aa1140314e45eaddd8d4b9148399caba8ac61a9476aec130eb369f7d526e741b1b6c47b1ca71bec21fa69aa3deaa13740dbffbc&amp;field1=&amp;field2=&amp;field3=&amp;field4=&amp;field5=&amp;field6=&amp;field7=&amp;field8=&amp;field9=Cancelled+by+user&amp;payment_source=payu&amp;PG_TYPE=&amp;bank_ref_num=&amp;bankcode=&amp;error=&amp;error_Message=");
 </script>

我从下面的片段中得到了这个回复

iabRef.executeScript(
   { code: "document.body.innerHTML" },
    function( values ) {
        alert(values[0]);
        console.log(values[0]);
    }
  );

所以我需要像mihpayid,mode,status等等这样的单独的属性值......

Answer 1

假设 values 或 values[0] 将具有:“mihpayid=403993715514374636&mode=&status=failure&unmappedstat”

然后你可以写一个函数如下:

   function extractScript(source){
     var pattern = /<script>(\w+)<\/script>/
     var matches = source.match(pattern);

     return matches[1];
   }

function getValue(source, key){
      var pattern = key+'=(\\w+)(&amp;)?';
      var expr = new RegExp(pattern);

      var result = source.match(expr);

      return result[1];
 }

然后在executeScript中:

iabRef.executeScript(
{ code: "document.body.innerHTML" },
  function( values ) {
   //incase values[0] contains result string
   console.log(getValue(values[0], 'mihpayid'))
   //or
   //incase values[0] contains result string
   console.log(getValue(values, 'mihpayid'))
}
);
