如果有一个名为“ method”的子输入，如何获取form.method属性值？
[英]How do I get form.method property value if there is a child input named “method”?
问题描述
I just found that I can use $('form').prop(name) to get input with that name within the form. 
我刚刚发现我可以使用$('form').prop(name)在表单中获取具有该名称的输入。 Then I experimented on other tags, and this won't work for div and body . 然后，我尝试了其他标签，但是这不适用于div和body 。 Now I don't have a way to tell if a form needs to post or get if there is an input named method , which unfortunately is true in one of my pages. 现在，我没有办法判断表单是否需要post或get是否有一个名为method的输入，但是不幸的是，在我的页面之一中，这是正确的。
Bonus: I can't get action of a form if there is an input named action inside it, either. 奖金：我不能action ，如果有一个名为输入表单的action里面，无论是。
<!doctype html>
<html lang="en">
<head>
<title>jQuery.prop()</title>
<script src="../../jquery-1.9.1.js"></script>
<script>
$(function() {
var method = $('form').prop('method');
console.log(method); // <select> element
var form = $('form')[0];
console.log(form.method); // <select> element
$('form').prop('method', 'get');
console.log(form.method); // still <select> element, but DOM inspector shows the form method is changed to "get"
form.method='get';
console.log(form.method); // still <select> element
});
</script>
</head>
<body>
<form action="/Test/Create" method="post">
<input type="text" name="content" value="" />
<select name="method">
<option value="phone">Phone</option>
<option value="email">Email</option>
</select>
</form>
</body>
</html>
So, how do I get form.method (or action) when there is an input with that name inside it? 因此，当输入中包含该名称时，如何获取form.method（或动作）？

You could just use jQuery's attr function, if I'm understanding the question correctly. 如果我正确理解了这个问题，则可以只使用jQuery的attr函数。
$('form').attr('action');
$('form').attr('method');

You should be able to use .attr on jQuery: 您应该能够在jQuery上使用.attr ：
var method = $('#myform').attr('method');
var action = $('#myform').attr('action');

As others have stated, the attribute is still there in the DOM. 正如其他人所说，该属性仍在DOM中。 If you open your example in Page Inspector or a similar tool, you'll find that document.forms[0].attributes has both an "action" and a "method" key in its map, which you can access via plain Javascript like so: 如果您在Page Inspector或类似工具中打开示例，则会发现document.forms [0] .attributes在其映射中同时具有“ action”和“ method”键，您可以通过诸如所以：
document.forms[0].attributes['method'].value
Or via jQuery like so: 或像这样通过jQuery：
$('form').attr('method');
