这将是使用jQuery选择的答案的一个版本。

// Post to the provided URL with the specified parameters.
function post(path, parameters) {
    var form = $('<form></form>');

    form.attr("method", "post");
    form.attr("action", path);

    $.each(parameters, function(key, value) {
        var field = $('<input></input>');

        field.attr("type", "hidden");
        field.attr("name", key);
        field.attr("value", value);

        form.append(field);
    });

    // The form needs to be a part of the document in
    // order for us to be able to submit it.
    $(document.body).append(form);
    form.submit();
}

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(); 
}

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。

Try

函数post_to_url（url，obj）{let id=`form_${+new Date（）}`；文档.body.innerHTML+=`<form id=“${id}”action=“${url}”method=“POST”>$｛Object.keys（obj）.map（k=>`<input-type=“hidden”name=“${k}”value=“${obj[k]}”>`)}</form>`this[id].submit（）；}//TEST-在第二个参数对象中可以有更多的键函数jump（）｛post_to_url（'https://example.com/'，{'q'：'‘}）；}打开chrome>网络并按下按钮：<button onclick=“jump（）”>发送POST</button>

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!

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();
}
