有时,你需要Post数据到另一个页面上,那么你就需要构建一个Form表单
<form id="postform" name="postform" method="post">
<input name="msg" value=""/>
</form>
代码如下:
document.write("<form ..."
//document.write("<iframe src=\"about:blank\" name=\"hiddenFrame\" id=\"hiddenFrame\" width=\"0\" height=\"0\" frameborder=\"0\"></iframe>");
用如下js提交不起作用,因为打到页面上的form不是一个对象,而是一个字符串
// theForm.action = "http://msg.baihe.com/tortoise/pages/tortoise/sm_gb2312.jsp?ReturnURL="+strReturnURL;
// document.getElementById("Pathid").value="3070";
// document.getElementById("Title").value="你好!";
// document.getElementById("Content").value="我把你设为重点关注了,咱们聊聊吧:)";
// document.getElementById("CloseWindow").value="1";
所以你需要自己动态创建form对象,用如下方法实现:
var form_feedback = document.createElement("form");
document.body.appendChild(form_feedback);
var i = document.createElement("input");
i.type = "hidden";
i.name = "Title";
i.value = "你好!";
form_feedback.appendChild(i);
var j=document.createElement("input");
j.type="hidden";
j.name="Content";
j.value="我把你设为重点关注了,咱们聊聊吧:)";
form_feedback.appendChild(j);
var hiddenIframe=document.createElement("iframe");
hiddenIframe.src="about:blank";
hiddenIframe.name="hiddenFrame";
hiddenIframe.id="hiddenFrame";
hiddenIframe.width="0";
hiddenIframe.height="0";
hiddenIframe.frameborder="0";
form_feedback.appendChild(hiddenIframe);
form_feedback.action = "http://msg.baihe.com/tortoise/pages/tortoise/sm_gb2312.jsp?ReturnURL=";
form_feedback.target = "hiddenFrame";
form_feedback.method = "post";
form_feedback.submit();
