我不确定标题是否准确。我仍然熟悉jQuery / JavaScript,所以请随时纠正我的语法/术语。
问题:我有一个表单页面,当用户点击发送时,我需要阅读并验证用户提供的数据。我遇到问题的数据是联系人数据。默认情况下,表单会列出两个联系人有一个按钮,允许用户动态地一次添加一个新的联系人到页面。因此,我的代码可能需要在此页面上验证数十或数百个联系人。我无法更改表单的代码/格式。我只能添加Javascript / jQuery来验证数据。
每个联系人都在重复包装中设置,如下所示:
<div class="ff-sec-repeat-wrapper">
<div class="ff-item-row">
<div class="ff-col-1 ff-label-col">LABELS&STUFF</div>
<div class="ff-col-2 ff-field-col">

以上是基本设置。每个重复包装器包含多行具有不同联系人的数据。每个联系人都有许多字段,例如LastName,EmailAddress,ContactRole等。但我怀疑,一旦我理解了如何访问其中一个,其他人将基本上以相同的方式访问。
重要的是(我相信):每个新的联系人ID都是使用Alpha_Number_组合顺序迭代的。因此,在上面,第一个联系人的FirstName ID是Application__c.Contact.A_1_.FirstName
,而eigth联系人的标识是Application__c.Contact.A_8_.FirstName
。此数字会更改为LastName
和EmailAddress
等所有其他联系人字段。
至少,如何检索所有联系人&#39;电子邮件地址成阵列?这样我就可以检查重复的电子邮件地址,并将提供的电子邮件地址与我已经检索过的其他数据相匹配。
答案 0 :(得分:1)
因此,您正在尝试弄清楚如何验证以下内容,而无需手动为&#34;联系人1,联系人2,...,联系人8&#34;等进行验证?< / p>
使用querySelectorAll
将是您的朋友。我们可以使用它来获取所有重复包装并将它们添加到数组中,然后您可以循环遍历该数组以进行验证。
这是一个简单的例子。出于演示目的,它将触发虚假名称并将两个有效名称添加到对象。当然,您可以使用自己的验证以及从那里做的任何事情来替换它。我认为你实际上正在寻找的是一种循环不确定数量的领域的方法;这
querySelectorAll
和一个简单的循环:
for( i = START; i <= NUM_OF_ITEMS; i++ ){
将简单的工作。请查看以下代码段:
// Run this code when #myform is submitted
document.querySelector('#myform').addEventListener("submit", function(e){
e.preventDefault(); // Prevent page load for demo purposes
var object = {},
valid = 0;
// Grab an array of all the repeat-wrapper fields
var fields = document.querySelectorAll('.ff-sec-repeat-wrapper');
// Loop through that array, it will stop when total # of `repeat-wrappers` has been reached
for( i = 1; i <= fields.length; i++ ){
// The "magic" here is the '+ i +', which is replaced with the current iteration number
// Since i will never be greater than fields.length, it will only run as much as long as needed
FirstName = document.getElementById('Membership_Application__c.Contact.A_'+ i +'_.FirstName').value;
LastName = document.getElementById('Membership_Application__c.Contact.A_'+ i +'_.LastName').value;
//Example Fields:
//Email = document.getElementById('Membership_Application__c.Contact.A_'+ i +'_.Email').value;
//SomeField = document.getElementById('Membership_Application__c.Contact.A_'+ i +'_.SomeField').value;
contact = []; // For demo purposes we're making an associative array of valid contacts
// Put your validation here
// Demo validation will only kick out the fake name "Foo Bar"
if( FirstName != 'Foo' ) contact.push( FirstName );
if( LastName != 'Bar' ) contact.push( LastName );
// If contact is valid, add it to our object
if( contact.length > 0 ) object[valid++] = contact;
}
console.log( object ); // Will contain 0:John, 1:Jane - having skipped `Foo` for not meeting out validation
});
