Question

var form = $('<form/>', {
    action: 'SupportRequest', 
    method: 'POST', 
    name: 'myForm', 
    id: 'myForm'
}).appendTo('body');

我必须在创建表单时手动添加enctype="multipart/form-data"，我该怎么做才能使上面的代码看起来像

<form class="hidden" id="myForm" mrthod="post" enctype = "multipart/form-data" action="myservlet">

还请告诉我如何手动制作class ='hidden'

Answer 1

您可以将它们添加到您已提供的对象的参数中：

var form = $('<form/>', {
    action: 'SupportRequest', // this should be 'myservlet' to match the HTML you gave
    method: 'POST', 
    name: 'myForm', 
    id: 'myForm',
    enctype: 'multipart/form-data',
    class: 'hidden'
}).appendTo('body');

Answer 2

您可以创建一个包含所有必要标记的字符串，并使用jQuery注入它。

var htmlForm = '<form class="hidden" id="myForm" mrthod="post" enctype = "multipart/form-data" action="myservlet">';
$("body").append(htmlForm);

以jquery形式添加enctype
