JavaScript发布请求，例如表单提交

动态创建

<input>

表单并提交

function post(path, params, method='post') {  // The rest of this pre assumes you are not using a library.  // It can be made less wordy 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：

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

编辑 ：既然已经被大肆抨击了，我猜人们会大量复制粘贴。因此，我添加了

hasOwnProperty
