open Method

DHTML文档教程

---

This method works in two ways. It opens a document to collect the output of the write and writeln methods. In this case, only the first two parameters, sUrl and sName are used. When values for the additional parameters are specified, this method opens a window in the same way as the window.open method for the window object.

Parameters

DHTML代码范例

The following example shows how to use the open method to replace the current document with a new document and display the HTML markup contained in the variable sMarkup.

<HTML>
<HEAD>
<TITLE>First Document</TITLE>
<script>
function replace(){
var oNewDoc = document.open("text/html", "replace");
var sMarkup = "<HTML><HEAD><TITLE>New Document</TITLE><BODY>Hello, world</BODY></HTML>";
oNewDoc.write(sMarkup);
oNewDoc.close();
}
</script>
</HEAD>
<BODY>
<h1>I just want to say</h1><br>
<!--Button will call the replace function and replace the current page with a new one-->
<Input type ="button" value = "Finish Sentence" onclick="replace();">
</BODY>
</html>
