How do I get data from php array into clientside array ( maybe javascript ) ?

Hi,

I have a mysql table contain a glossary
which I would like to accesses from the webbrowser.

The table is simple, just two columns so could be handled
by an associatve array in php.

So I guess I need to get the data into javascript or some
other client-side code.

The table contains about 2000 rows and I want to use it so that
when the mouse hovers over a technical word, the glossary
explanation is shown in a window.

What route would you suggest ?

Thanks.

store it as a simple javascript object:

Hope this helps you.

Thanks for helping
That looks good.

Only thing is; I have not used javascript objects before so I am a bit in the dark.

So when I have my object how would I use it ?
Is it like a php array only in javascript ?

do I use foreach() to list its rows ?

what I need to do is grab the word that the mouse is
hovering over and look it up in the "obj" index and
display the associated string on the screen in a box
(maybe a floating movable little window ?? )

Where would I find the relevant js functions for that ?

Thanks.

You will need to loop through it like an array. JavaScript doesn't have a foreach keyword, but it can do a "for in" :

<script type="text/javascript">

var obj = {

	member1 : 'value1',
	another : 'another2',
	data3   : 'datavalue3'

}, i;

for (i in obj) {if (obj.hasOwnProperty(i)) {

	document.write(i + ' = ' + obj[i] + '<br />');

}}

</script>

Output

member1 = value1
another = another2
data3 = datavalue3

Obviously you can build a better layout during the loop using html, assigning a title tag with the values could be a temporary solution as well.

Believe it or not, I'm much better at JavaScript than PHP
