好吧，希望我读过所有其他帖子，这样我就不会浪费时间从Rakesh Pai的回答中创建这些帖子了。这里有一个递归解决方案，可以处理数组和对象。不依赖jQuery。

添加了一个段来处理整个表单应该像数组一样提交的情况。（即，项目列表周围没有包装对象）

/**
 * Posts javascript data to a url using form.submit().  
 * Note: Handles json and arrays.
 * @param {string} path - url where the data should be sent.
 * @param {string} data - data as javascript object (JSON).
 * @param {object} options -- optional attributes
 *  { 
 *    {string} method: get/post/put/etc,
 *    {string} arrayName: name to post arraylike data.  Only necessary when root data object is an array.
 *  }
 * @example postToUrl('/UpdateUser', {Order {Id: 1, FirstName: 'Sally'}});
 */
function postToUrl(path, data, options) {
    if (options === undefined) {
        options = {};
    }

    var method = options.method || "post"; // Set method to post by default if not specified.

    var form = document.createElement("form");
    form.setAttribute("method", method);
    form.setAttribute("action", path);

    function constructElements(item, parentString) {
        for (var key in item) {
            if (item.hasOwnProperty(key) && item[key] != null) {
                if (Object.prototype.toString.call(item[key]) === '[object Array]') {
                    for (var i = 0; i < item[key].length; i++) {
                        constructElements(item[key][i], parentString + key + "[" + i + "].");
                    }
                } else if (Object.prototype.toString.call(item[key]) === '[object Object]') {
                    constructElements(item[key], parentString + key + ".");
                } else {
                    var hiddenField = document.createElement("input");
                    hiddenField.setAttribute("type", "hidden");
                    hiddenField.setAttribute("name", parentString + key);
                    hiddenField.setAttribute("value", item[key]);
                    form.appendChild(hiddenField);
                }
            }
        }
    }

    //if the parent 'data' object is an array we need to treat it a little differently
    if (Object.prototype.toString.call(data) === '[object Array]') {
        if (options.arrayName === undefined) console.warn("Posting array-type to url will doubtfully work without an arrayName defined in options.");
        //loop through each array item at the parent level
        for (var i = 0; i < data.length; i++) {
            constructElements(data[i], (options.arrayName || "") + "[" + i + "].");
        }
    } else {
        //otherwise treat it normally
        constructElements(data, "");
    }

    document.body.appendChild(form);
    form.submit();
};

您可以使用jQuery的触发器方法提交表单，就像按下按钮一样，

$('form').trigger('submit')

它将在浏览器上提交。

最简单的方法是使用Ajax Post Request：

$.ajax({
    type: "POST",
    url: 'http://www.myrestserver.com/api',
    data: data,
    success: success,
    dataType: dataType
    });

哪里：

数据是一个对象dataType是服务器期望的数据（xml，json、脚本、文本、html）url是RESt服务器或服务器端接受HTTP-POST的任何函数的地址。

然后在成功处理程序中使用类似window.location的内容重定向浏览器。

这是rakesh的答案，但支持数组（这在形式上很常见）：

纯javascript：

function post_to_url(path, params, method) {
    method = method || "post"; // Set method to post by default, if not specified.

    // The rest of this code assumes you are not using a library.
    // It can be made less wordy if you use one.
    var form = document.createElement("form");
    form.setAttribute("method", method);
    form.setAttribute("action", path);

    var addField = function( key, value ){
        var hiddenField = document.createElement("input");
        hiddenField.setAttribute("type", "hidden");
        hiddenField.setAttribute("name", key);
        hiddenField.setAttribute("value", value );

        form.appendChild(hiddenField);
    }; 

    for(var key in params) {
        if(params.hasOwnProperty(key)) {
            if( params[key] instanceof Array ){
                for(var i = 0; i < params[key].length; i++){
                    addField( key, params[key][i] )
                }
            }
            else{
                addField( key, params[key] ); 
            }
        }
    }

    document.body.appendChild(form);
    form.submit();
}

哦，这里是jquery版本：（代码略有不同，但归结起来是相同的）

function post_to_url(path, params, method) {
    method = method || "post"; // Set method to post by default, if not specified.

    var form = $(document.createElement( "form" ))
        .attr( {"method": method, "action": path} );

    $.each( params, function(key,value){
        $.each( value instanceof Array? value : [value], function(i,val){
            $(document.createElement("input"))
                .attr({ "type": "hidden", "name": key, "value": val })
                .appendTo( form );
        }); 
    } ); 

    form.appendTo( document.body ).submit(); 
}

我用来发布和引导用户自动到另一个页面的方法是只写一个隐藏表单，然后自动提交。请确保隐藏表单在网页上绝对不会占用空间。代码应该是这样的：

    <form name="form1" method="post" action="somepage.php">
    <input name="fielda" type="text" id="fielda" type="hidden">

    <textarea name="fieldb" id="fieldb" cols="" rows="" style="display:none"></textarea>
</form>
    document.getElementById('fielda').value="some text for field a";
    document.getElementById('fieldb').innerHTML="some text for multiline fieldb";
    form1.submit();

自动提交申请

自动提交的应用程序会将用户自动放入另一页的表单值引导回该页。此类应用程序如下所示：

fieldapost=<?php echo $_post['fielda'];>
if (fieldapost !="") {
document.write("<form name='form1' method='post' action='previouspage.php'>
  <input name='fielda' type='text' id='fielda' type='hidden'>
</form>");
document.getElementById('fielda').value=fieldapost;
form1.submit();
}

在表单中动态创建＜input＞并提交

/**
 * sends a request to the specified url from a form. this will change the window location.
 * @param {string} path the path to send the post request to
 * @param {object} params the parameters to add to the url
 * @param {string} [method=post] the method to use on the form
 */

function post(path, params, method='post') {

  // The rest of this code assumes you are not using a library.
  // It can be made less verbose if you use one.
  const form = document.createElement('form');
  form.method = method;
  form.action = path;

  for (const key in params) {
    if (params.hasOwnProperty(key)) {
      const hiddenField = document.createElement('input');
      hiddenField.type = 'hidden';
      hiddenField.name = key;
      hiddenField.value = params[key];

      form.appendChild(hiddenField);
    }
  }

  document.body.appendChild(form);
  form.submit();
}

例子：

post('/contact/', {name: 'Johnny Bravo'});

编辑：既然这件事得到了如此多的支持，我猜人们会大量复制粘贴这件事。所以我添加了hasOwnProperty检查，以修复任何意外的错误。
