Question

At the moment I’ve got one function to check, if a webpage is reachable. I’ll call this function at about 100 times in a while-loop, which means it sometime lasts 5 minutes to check all these 100 webpages.
I never before used ajax but I would think that it would be a good idea to solve this problem with ajax, but I never used ajax before and have no idea, how to start. Could you give me a good hint? Thanks for every answer!

Answer 1

I would use jquery-ajax, makes it simpler.
So put jquery on your site to start.

This is how jquery ajax works:

$.ajax({
    type: 'POST',
    url: '--LINK TO PHP/ASP...---',  // Place the link that has the command
    data: dataString,  // dataString is a json encode of the data that is sent to the file
    dataType : 'json',
    beforeSend:function(){
        // Before you send the info, do what you want here (ie loading gif...)
    },
    success:function(data){
        // If it is successful, then it will do what you want here.         
    }
});

I hope this helps.
