Rakesh Pai的回答令人惊讶，但当我试图发布一个名为submit的表单时，我（在Safari中）遇到了一个问题。例如，post_to_url（“http://google.com/“，｛submit：”submit“｝）；。我已经稍微修补了该函数，以避免这种变量空间冲突。

function post_to_url(path, params, method) {
    method = method || "post";

    var form = document.createElement("form");
    
    //Move the submit function to another variable
    //so that it doesn't get overwritten.
    form._submit_function_ = form.submit;
    
    form.setAttribute("method", method);
    form.setAttribute("action", path);

    for(var key in params) {
        var hiddenField = document.createElement("input");
        hiddenField.setAttribute("type", "hidden");
        hiddenField.setAttribute("name", key);
        hiddenField.setAttribute("value", params[key]);

        form.appendChild(hiddenField);
    }

    document.body.appendChild(form);
    form._submit_function_(); //Call the renamed function.
}
post_to_url("http://google.com/", { submit: "submit" } ); //Works!

jQuery插件，用于POST或GET重定向：

https://github.com/mgalante/jquery.redirect/blob/master/jquery.redirect.js

要进行测试，请包含上述.js文件或将类复制/粘贴到代码中，然后使用此处的代码，将“args”替换为变量名，将“value”替换为这些变量的值：

$.redirect('demo.php', {'arg1': 'value1', 'arg2': 'value2'});

这在我的情况下非常有效：

document.getElementById("form1").submit();

您可以在以下函数中使用它：

function formSubmit() {
     document.getElementById("frmUserList").submit();
} 

使用此选项，您可以发布所有输入值。

下面是我如何使用jQuery编写它的。在Firefox和Internet Explorer中测试。

function postToUrl(url, params, newWindow) {
    var form = $('<form>');
    form.attr('action', url);
    form.attr('method', 'POST');
    if(newWindow){ form.attr('target', '_blank'); 
  }

  var addParam = function(paramName, paramValue) {
      var input = $('<input type="hidden">');
      input.attr({ 'id':     paramName,
                 'name':   paramName,
                 'value':  paramValue });
      form.append(input);
    };

    // Params is an Array.
    if(params instanceof Array){
        for(var i=0; i<params.length; i++) {
            addParam(i, params[i]);
        }
    }

    // Params is an Associative array or Object.
    if(params instanceof Object) {
        for(var key in params){
            addParam(key, params[key]);
        }
    }

    // Submit the form, then remove it from the page
    form.appendTo(document.body);
    form.submit();
    form.remove();
}

您可以使用类似jQuery的库及其$.post方法。

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();
