有時,你需要Post數據到另一個頁面上,那麼你就需要構建一個Form表單
<form id="postform" name="postform" method="post"> <input name="msg" value=""/> </form>
復制代碼 代碼如下:
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,因為打到頁面上的form不是一個對象,而是一個字符串
// 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="我把你設為重點關注了,咱們聊聊吧:)"; // document.getElementById("CloseWindow").value="1";
所以你需要自己動態創建form對象,用如下方法實現:
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="我把你設為重點關注了,咱們聊聊吧:)"; 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();
