Ajax to Read page content ( Same domain )

Question

I am using following JavaScript/Ajax to read page content, This script works great but it loads only Half of the page contents of shoppingcart.asp, I want the shoppingcart.asp to load fully and then show all webpage contents, is this possible, shall I add a delay?

<script language="Javascript"> var anUrl = "http://www.abc.com/shoppingcart.asp"; var myRequest = new XMLHttpRequest(); callAjax(anUrl); function callAjax(url) { myRequest.open("GET", url, true); myRequest.onreadystatechange = responseAjax; myRequest.setRequestHeader("Cache-Control", "no-cache"); myRequest.send(null); } function responseAjax() { if(myRequest.readyState == 4) { if(myRequest.status == 200) { result = myRequest.responseText; alert(result); alert("we made it"); } else { alert( " An error has occurred: " + myRequest.statusText); } } } </script>

@SomeKittens The content is not displayed from <Html> to </html> it dislays other page html almost 30-40% and cuts other HTML — TSCAmerica.com

@user580950 — It looks like it is being cut off due to the limitations in how much text can be entered into an alert(). Use something else to test it. — Quentin

JavaScript's alert() has a maximum amount of text that it can contain. If you want to check large amounts of text, there are two options:

You can log it in the browser's console using console.log(text)
You can put it into a div using document.getElementById("divID").innerHTML = text
