javascript - Insert external page html into a page html

Question

I'd like to load/insert an external html page into my web page. Example :

<b>Hello this is my webpage</b>
You can see here an interresting information :

XXXX

Hope you enjoyed

the XXXX should be replaced by a small script (the smaller as possible) that load a page like http://www.mySite.com/myPageToInsert.html

I found the following code with jquery :

<script>$("#testLoad").load("http://www.mySite.com/myPageToInsert.html");</script>    
<div id="testLoad"></div>

I would like the same without using an external javascript library as jquery...

Answer 1

There are 2 solutions for this (2 that I know at least):

1. Iframe -> this one is not so recommended

2. Send an ajax request to the desired page.

Here is a small script:

<script type="text/javascript">

function createRequestObject() {
    var obj;
    var browser = navigator.appName;
    if (browser == "Microsoft Internet Explorer") {
        obj = new ActiveXObject("Microsoft.XMLHTTP");
    } else {
        obj = new XMLHttpRequest();
    }
    return obj;
}

function sendReq(req) {   
    var http = createRequestObject();
    http.open('get', req);
    http.onreadystatechange = handleResponse;
    http.send(null);
}

function handleResponse() {    
    if (http.readyState == 4) {
        var response = http.responseText;
        document.getElementById('setADivWithAnIDWhereYouWantIt').innerHTML=response;
    }
}

 sendReq('yourpage');
//previously </script> was not visible
</script>
