从引荐来源网址解析答案

【问题标题】：Parse from referrer URL从引荐来源网址解析

【问题描述】：

我有以下 URL，它重定向到我在 Form Assembly 上的表单。我正在尝试在提交之前预先填写隐藏字段，以便客户不必填写两次。

state=CA&period=PERIOD_FIXED_30YEARS&loan=200000&ltv=80&transaction=54&property_type=34&fico=740&occupancy=49&cashout=0&rate=4.125&fees=510&points=0.204&trackingID=1445830871741638005

我的代码如下。我在控制台中没有收到任何错误。

需要注意的几点： 1. 表单是预构建的 HTML 并且已经在使用隐藏输入 2.我需要填写的隐藏字段有一个ID = tfa_XX

<script type="text/javascript">

// Parsing URL
function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
    results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
}

//Gathering the URL Parameters
var period = getParameterByName('period');
var loan = getParameterByName('loan');
var ltv = getParameterByName('ltv');
var transaction = getParameterByName('transaction');
var property_type = getParameterByName('property_type');
var fico = getParameterByName('fico');
var occupancy = getParameterByName('occupancy');
var cashout = getParameterByName('cashout');
var rate = getParameterByName('rate');
var fees = getParameterByName('fees');
var points = getParameterByName('points');
var trackingID = getParameterByName('trackingID');


function autoFill() {
//function to autoFill form
document.getElementById("tfa_49").value = period;
document.getElementById("tfa_50").value = loan;
}

</script>

感谢您的帮助！

【解决方案1】：

我可以使用以下内容在 Form Assembly 中执行此操作。然后我导出了完整的 HTML 并将其放置在 AEM 中。

<script type="text/javascript">


//Used to pull URL
  
const link = window.location.href;
const url = new URL(link);


//Function to get the URL parameters
function getParameterByName(name) {
  return url.searchParams.get(name);
}

//Gathering the URL Parameters and writing to console to check if parse is accurate -- Note the console.log can be removed if needed
var period = getParameterByName('period');
console.log(period);

var loan = getParameterByName('loan');
console.log(loan);

var ltv = getParameterByName('ltv');
console.log(ltv);

var transaction = getParameterByName('transaction');
console.log(transaction);

var property_type = getParameterByName('property_type');
console.log(property_type);

var fico = getParameterByName('fico');
console.log(fico);

var occupancy = getParameterByName('occupancy');
console.log(occupancy);

var cashout = getParameterByName('cashout');
console.log(cashout);

var rate = getParameterByName('rate');
console.log(rate);

var fees = getParameterByName('fees');
console.log(fees);

var points = getParameterByName('points');
console.log(points);

var trackingID = getParameterByName('trackingID');
console.log(trackingID);




//On load function to prefill the forms hidden fields
$( document ).ready(function() {
  document.getElementById("tfa_49").value = period;
  document.getElementById("tfa_50").value = loan;
  document.getElementById("tfa_51").value = ltv;
  document.getElementById("tfa_53").value = transaction;
  document.getElementById("tfa_54").value = property_type;
  document.getElementById("tfa_55").value = fico;
  document.getElementById("tfa_56").value = occupancy;
  document.getElementById("tfa_57").value = cashout;
  document.getElementById("tfa_58").value = rate;
  document.getElementById("tfa_59").value = fees;
  document.getElementById("tfa_60").value = points;
  document.getElementById("tfa_61").value = trackingID;
});


</script>
