Question

我正在使用js.cookie.js在读取URL参数后设置cookie值。接下来，我想用cookie值填充许多隐藏字段。读取URL值并设置cookie正在运行，但在隐藏字段中设置值无效。

这是脚本：

<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
<script src="http://example.com/scripts/js.cookie.js" type="text/javascript"></script>

<script>

// Parse the 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, " "));
}
// Give the URL parameters variable names

var visitor_id = getParameterByName('utm_visitor_id');
var medium = getParameterByName('utm_medium');
var source = getParameterByName('utm_source');
var campaign = getParameterByName('utm_campaign');
var content = getParameterByName('utm_content');
var term = getParameterByName('utm_term');
var count_of_sessions = getParameterByName('utm_count_of_sessions');
var count_of_page_views = getParameterByName('utm_count_of_page_views');

// Set the cookies

Cookies.set('utm_visitor_id', visitor_id, { expires: 90 });
Cookies.set('utm_medium', medium, { expires: 90 });
Cookies.set('utm_source', source, { expires: 90 });
Cookies.set('utm_campaign', campaign, { expires: 90 });
Cookies.set('utm_content', content, { expires: 90 });
Cookies.set('utm_term', term, { expires: 90 });
Cookies.set('utm_count_of_sessions', count_of_sessions, { expires: 90 });
Cookies.set('utm_count_of_page_views', count_of_page_views, { expires: 90 });


// Grab the cookie value and set the form field values
$(document).ready(function(){
	$('input[name=00N4100000NglQ2').val(utm_visitor_id);
	$('input[name=00N4100000NgleO').val(utm_medium);
	$('input[name=00N4100000NglpC').val(utm_source);
	$('input[name=00N4100000NglyY').val(utm_campaign);
	$('input[name=00N4100000NgmBh').val(utm_content);
	$('input[name=00N4100000NgmIs').val(utm_term);
	$('input[name=00N4100000NgmQw').val(utm_count_of_sessions);
	$('input[name=00N4100000NgmZ5').val(utm_count_of_page_views);
});

</script>

以下是表单中隐藏的字段，其中id =“contact-form”

<!-- Visitor ID: -->
  <input id="00N4100000NglQ2" maxlength="255" name="00N4100000NglQ2" size="20" type="hidden" value="" /> 

  <!-- Medium: -->
  <input id="00N4100000NgleO" maxlength="255" name="00N4100000NgleO" size="20" type="hidden" value="" /> 
  <!-- Source: -->

  <input id="00N4100000NglpC" maxlength="255" name="00N4100000NglpC" size="20" type="hidden" value="" /> 
  <!-- Campaign: -->
  <input id="00N4100000NglyY" maxlength="255" name="00N4100000NglyY" size="20" type="hidden" value="" /> 

  <!-- Content: -->
  <input id="00N4100000NgmBh" maxlength="255" name="00N4100000NgmBh" size="20" type="hidden" value="" /> 

  <!-- Term: -->
  <input id="00N4100000NgmIs" maxlength="255" name="00N4100000NgmIs" size="20" type="hidden" value="" /> 

  <!-- Count of Sessions: -->
  <input id="00N4100000NgmQw" maxlength="255" name="00N4100000NgmQw" size="20" type="hidden" value="" /> 

  <!-- Count of Pageviews: -->
  <input id="00N4100000NgmZ5" maxlength="255" name="00N4100000NgmZ5" size="20" type="hidden" value="" />

我想知道隐藏字段名称是否存在问题，例如“00N4100000NgmZ5”，它们是来自salesforce.com的自定义字段名称

感谢您的帮助。

Answer 1

您似乎错过了每个选择器中的结束括号。我说这是因为它无法将值插入输入字段。

此外，请确保在将这些值插入输入字段之前收集并存储这些值。

Answer 2

尝试在函数getParameterByName（）上面声明所有变量，并在函数内部加载变量及其值，在完成加载变量后立即添加jQuery函数作为简单$（函数）（）{}）。

我想问题是当你的$（document）.ready（）函数在页面加载时执行，并且没有值加载YET。
