I have a webpage that implements a set of tabs each showing different content. The tab clicks do not refresh the page but hide/unhide contents at the client side.

Now there is a requirement to change the page title according to the tab selected on the page ( for SEO reasons ). Is this possible? Can someone suggest a solution to dynamically alter the page title via javascript without reloading the page?



Update: as per the comments and reference on SearchEngineLand most web crawlers will index the updated title. Below answer is obsolete, but the code is still applicable.

You can just do something like, document.title = "This is the new page title.";, but that would totally defeat the purpose of SEO. Most crawlers aren't going to support javascript in the first place, so they will take whatever is in the element as the page title.

If you want this to be compatible with most of the important crawlers, you're going to need to actually change the title tag itself, which would involve reloading the page (PHP, or the like). You're not going to be able to get around that, if you want to change the page title in a way that a crawler can see.

You didn't say anything about file types so I used HTML-5 formats that work in Safari.

    <meta charset="UTF-8">
    <title> audio video</title>

    <audio id="audioInHTML" controls="controls">     
    <source src="audio.wav" type="audio/wav"/>

    <video id="videoInHTML" width="320" height="240" controls="controls">
      <source src="movie.mp4" type="video/mp4" />

    <div id="playButtonDiv" </div>

    <input type="button" value="PlaySoundAndVideo" onClick="PlaySoundAndVideo('videoInHTML'),PlaySoundAndVideo('audioInHTML')">



    function PlaySoundAndVideo(soundObj,videoObj) {
    var soundAndVideo=document.getElementById(soundObj,videoObj);;


    <style type="text/css">

    #playButtonDiv {

Yes then you need to create WebViewClient.

private class HelloWebViewClient extends WebViewClient {
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        return true;

Check Step No. 7 and 8 given in Hello WebView example..

You can mark a web reference as static or dynamic URL. If you choose dynamic then it will add the URL to the web.config which you can then change in your production environment.

If it is marked as static then it is compiled into the binary and is not changeable without a rebuild.

If it is already dynamic then the code looks for the dynamic URL and then if it can't find it then it uses the default original. Therefore, you can just add an entry into the web config such as:

        <setting name="MySystem_MyService" serializeAs="String">

What you should do is implement your own controls (or use an existing set such as videojs)
