Does form data still transfer if the input tag has no name?
提问by Jamie Kitson
For efficiency purposes I am wondering if a file or text in a textarea still gets transferred to the server if you omit the name attribute or set it to null. eg
为了提高效率，我想知道如果省略 name 属性或将其设置为 null，textarea 中的文件或文本是否仍会传输到服务器。例如
<input type="file" id="file" name="">
<textarea id="text" name="">
I notice that the data is not available at the server if you do this.
我注意到如果你这样做，数据在服务器上不可用。

No.
不。
I checked this in all browsers - the fields with empty/missing name are missing in POST/GET request from browser. It doesn't matter if they have or don't have id (my thought was that browsers might use id for name but no).
我在所有浏览器中检查了这一点 - 来自浏览器的 POST/GET 请求中缺少名称为空/缺失的字段。他们有没有 id 都没有关系（我的想法是浏览器可能使用 id 作为名称，但没有）。

it won't work directly but you can assign them through AJAX calls in JavaScript, idk really know if this really has any application in the real world ( one could be the obfuscation of the parameters that the server expects )
它不会直接工作，但您可以通过 JavaScript 中的 AJAX 调用分配它们，idk 真的知道这在现实世界中是否真的有任何应用程序（可能是服务器期望的参数混淆）

有
<form id="login" method="post" action="someurl">
<input id="username" type="text" />
<input id="password" type="password" />
<input type="submit" value="login" />
</form>
JS to process would be (using jQuery to process ajax)
要处理的 JS 将是（使用 jQuery 处理 ajax）
$("#login").on("submit",function(ev){
$.post("someurl",{
usrn: $("#username").val,
pwd: $("#password").val
},function(ev){
//this is the callback function that runs when the call is completed successfully
});
}
/*second argument on $.post is and object with data to send in a post request
usrn would be the name of the parameter recived in the server
same for pwd "#username" and "#password" are the id's html attribute for the field
'.val' is the jquery object's attribute in which jquery access the value in the text box
"$()" or it's equivalent "jQuery()" works like an object constructor that fills
the attributes with the
DOM data that cover the css selector that this function expects as a parameter*/
please NOTE code might not be fully correct since i haven't test it but the logic behind it should be self-explanatory
请注意代码可能不完全正确，因为我还没有测试过它，但它背后的逻辑应该是不言自明的
