下载手册取决于隐藏字段值

Question

我有一个 html 网站并使用带有表单的小册子下载选项。每个项目我都有很多表格。我只需要一个下载小册子的表格，取决于项目的隐藏输入值。

  jQuery(".form-js-pop-vedam").submit(function () {
		var thisform = jQuery(this);
		jQuery('.required-error',thisform).remove();
		
		var pmail	= jQuery("#pmail").val();
		var pphone	= jQuery("#pphone").val();
		var psubject	= jQuery("#psubject").val();
		
		var data = {'pmail':pmail,'pphone':pphone,'psubject':psubject}
		
		 if (pmail == "") {
			 jQuery("#pmail").after('<span class="form-description  required-error">Required field.</span>');
		}else {
			jQuery("#pmail").parent().find('.required-error').remove();
		}
		if (pphone == "") {
			jQuery("#pphone").after('<span class="form-description   required-error">Required field.</span>');
		}else {
			jQuery("#pphone").parent().find('.required-error').remove();
		}
		
		if ( pmail != "" && pphone != "" ) {
			jQuery.post("contact_us_pop-vedam.php",data,function (result) {
				if (result == "done") {
					
    thisform.prepend("<div class='alert-message success-amairo'><i      class='icon-ok'></i><p><span>Vedam brochure was sent to your mail. Thank    you!</span></p></div>");
					jQuery("#pmail").val("");
					jQuery("#pphone").val("");
					
				}
			});
		 }
		return false;
	 });
	
 
    <form class="form-style form-js-pop-vedam" action="contact_us_pop-vedam.php" method=post>
  <input type="hidden" name="psubject" id="psubject" value="Brochure   Download from Vedam Page">

Answer 1

让我们大致谈谈单词（隐藏）.. 我们有 2 个案例

第一种情况：type="hidden" 的输入你可以使用这样的选择器

在css中

input[type="hidden"]{}

在js中

$('input[type="hidden"]') // you can use .val()  or .attr() depending on data you want from it

检查表单是否有隐藏类型的输入

if($('form').find('input[type="hidden"]').length > 0){ // in submit event use $(this).find   instead if $('form').find
   // yes this is input with type hidden here
}else{
   // no input with type hidden here
}

当你说 （取决于隐藏的输入值） 你可以用

if($('form').find('input[type="hidden"]').val() == 'something'){ // in submit event use $(this).find   instead if $('form').find
       // type input hidden value = something
    }else{
       // type input hidden value not = something
    }

第二种情况： :hidden 和 :visible 是关于元素是否可见，我认为您在这里不需要它
