是否有一种简单的单行方式来获取表单的数据，就像以经典的仅html方式提交表单一样?
例如:
<form>
<input type="radio" name="foo" value="1" checked="checked" />
<input type="radio" name="foo" value="0" />
<input name="bar" value="xxx" />
<select name="this">
<option value="hi" selected="selected">Hi</option>
<option value="ho">Ho</option>
</form>
输出:
{
"foo": "1",
"bar": "xxx",
"this": "hi"
}
像这样的东西太简单了，因为它没有(正确地)包括文本区域，选择，单选按钮和复选框:
$("#form input").each(function () {
data[theFieldName] = theFieldValue;
});
显示表单输入元素字段和输入文件提交您的表单没有页面刷新和抓取所有值与文件包括在这里
<form id="imageUploadForm" action="" method="post" enctype="multipart/form-data">
<input type="text" class="form-control" id="fname" name='fname' placeholder="First Name" >
<input type="text" class="form-control" name='lname' id="lname" placeholder="Last Name">
<input type="number" name='phoneno' class="form-control" id="phoneno" placeholder="Phone Number">
<textarea class="form-control" name='address' id="address" rows="5" cols="5" placeholder="Your Address"></textarea>
<input type="file" name="file" id="file" >
<input type="submit" id="sub" value="Registration">
</form>
on Submit button page will send ajax request to your php file.
$('#imageUploadForm').on('submit',(function(e)
{
fname = $('#fname').val();
lname = $('#lname').val();
address = $('#address').val();
phoneno = $('#phoneno').val();
file = $('#file').val();
e.preventDefault();
var formData = new FormData(this);
formData.append('file', $('#file')[0]);
formData.append('fname',$('#fname').val());
formData.append('lname',$('#lname').val());
formData.append('phoneno',$('#phoneno').val());
formData.append('address',$('#address').val());
$.ajax({
type:'POST',
url: "test.php",
//url: '<?php echo base_url().'edit_profile/edit_profile2';?>',
data:formData,

}

基于neuront的响应，我创建了一个简单的JQuery方法，在键值对中获取表单数据，但它适用于多选择和name='example[]'的数组输入。
下面是它的用法:
var form_data = $("#form").getFormObject();
您可以在下面找到它的定义及其工作方式的示例。
// Function start
$.fn.getFormObject = function() {
var object = $(this).serializeArray().reduce(function(obj, item) {
var name = item.name.replace("[]", "");
if ( typeof obj[name] !== "undefined" ) {
if ( !Array.isArray(obj[name]) ) {
obj[name] = [ obj[name], item.value ];
} else {
obj[name].push(item.value);
}
} else {
obj[name] = item.value;
}
return obj;
}, {});
return object;
}
// Function ends
// This is how it's used
$("#getObject").click( function() {
var form_data = $("#form").getFormObject();
console.log(form_data);
});
/* Only to make view better ;) */
#getObject {
padding: 10px;
cursor:pointer;
background:#0098EE;
color:white;
display:inline-block;
}
