Dynamic Hint using Ajax

I was following this good Ajax tutorial at W3 and currently practising dynamic suggestion using XMLHTTPRequest (http://www.w3schools.com/ajax/ajax_aspphp.asp)

My problem with it is everytime I key in the text field, onkeyup will trigger server page (gethint.asp/gethint.php). And everytime the server page is triggered, it recreates the name array. Since in the example, it's only 30 names, then it's still fast. But what if there's like 100,000 names? Everytime I key in the text field, it will recreate the whole 100,000 array!!

Is there any better way, like to create name array into memory when the page is loaded first time. And when I key in the text field, it will check in the memory instead of recreate name array again?

Sure, but that'd be on the server side, not the client side. (Or at least it could be.) There are many ways of going about this, depending on the back-end mechanism used to get the data.

Yea any idea how to go about it? Kinda blank-minded for now, any hints or guides? Thanks in advance

I tried <body onload="loadInit()"> to request the server page to create array when the client page is loaded.
But that doesn't work because on subsequent requests to the server page, the array is gone.
