JavaScript in the page there are 2 common ways, one is JS made external files, page directly call, the following is a line of Shanghai SEO Lab Code:

the following references:


<script language= "JavaScript" src= "Http://www.seotest.cn/script/common.js" type= "Text/javascript" ></ Script>

The other is to write the JS code directly on the page, for example:

the following references: <script language= "JavaScript" >


try{


var elscript = document.createelement ("script");


Elscript.setattribute ("Language", "JavaScript");


Elscript.setattribute ("src", "http://www.seotest.cn/function/c_html_js.asp?act=batch" + "&view=" + Escape (  Strbatchview) + "&inculde=" + Escape (Strbatchinculde) + "&count=" + Escape (strbatchcount));


document.getElementsByTagName ("body") [0].appendchild (Elscript);


        }


catch (e) {};


</script>

From the search engine crawl point of view, the first does not contain any text information, so the search engine cannot extract content from it. But the second if the text content, the search engine can crawl the contents of it?

Experiment idea: Make a only JS code page, JS code contains Chinese content. Then wait for the search engine to include the results in Serp and a snapshot of the page.

Experiment page: ([Url=http://www.seotest.cn/testpage/tp009.html]http://www.seotest.cn/testpage/tp009.html[/url])

The following is the referenced content:<html>


<head>


<meta http-equiv= "Content-type" content= "HTML; charset=gb2312 "/>


<title>2007-9-25 The beginning of the Mid-Autumn Festival experiment </title>


</head>





<body>


<script type= "Text/javascript" >


Document.writeln ("JS Crawl Experiment:<br>");


Document.writeln ("Try to put the text in the JS code, will be search engine crawl to it?" ");


</SCRIPT>


</body>


</html>
