Body
<p>Here is my javascript code which ping Google for every 10 seconds and display the connection status to html MonitorInformation element. But when I click the html file to debug, the information displayed at MonitorInformation element is always "Connecting...wait". I have debugged for some time but can not figure out. Any ideas what is wrong with my code?</p> <p>Html code:</p> <pre><code><html xmlns="http://www.w3.org/1999/xhtml"> <head> <script src="Monitor.js" type="text/javascript"></script> <title>Web Site Monitor</title> </head> <body onload="setup()"> <div id="MonitorInformation">Connecting...wait</div> </body> </html> </code></pre> <p>Java script code:</p> <pre><code>function setup() { window.setInterval(PingWebSite, (10 * 1000)); } function PingWebSite() { conObj = new ActiveXObject("Msxml2.XMLHTTP"); conObj.open("GET", "http://www.google.com", true); conObj.onreadystatechange = function() { if (conObj.readyState === 4) { if (conObj.status === 200) { loading.innerText = "Service is available"; } else { MonitorInformation.innerText = "Service is not available"; } } else { MonitorInformation.innerText = "Connecting to www.google.com ..."; } } } </code></pre> <p>EDIT 1: my fix using JSON</p> <pre><code>function setup() { window.setInterval(PingWebSite, (10 * 1000)); } function PingWebSite() { var http_request = new XMLHttpRequest(); http_request.open("GET", "http://www.google.com", true); http_request.send(null); http_request.onreadystatechange = function() { if (http_request.readyState == 4) { if (http_request.status == 200) { MonitorInformation.innerText = "Connection ok"; alert("ok"); } else { MonitorInformation.innerText = "Connection fail"; alert("fail"); } http_request = null; } }; } <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script src="Monitor.js" type="text/javascript"></script> <title>Web Site Monitor</title> </head> <body onload="setup()"> <div id="MonitorInformation">Connecting...wait</div> </body> </html> </code></pre> <p>thanks in advance, George</p>

1. COJSON won't work, you need to use JSONP, which only works if the service you are hitting provides it.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
