对于它的价值，这里是以前提供的代码封装在一个函数中。

openWindowWithPost("http://www.example.com/index.php", {
          p: "view.map",    coords: encodeURIComponent(coords)});

功能定义：

function openWindowWithPost(url, data) {
          var form = document.createElement("form");    form.target = "_blank";    form.method = "POST";    form.action = url;    form.style.display = "none";    for (var key in data) {
              var input = document.createElement("input");        input.type = "hidden";        input.name = key;        input.value = data[key];        form.appendChild(input);    }    document.body.appendChild(form);    form.submit();    document.body.removeChild(form);}
