hi, please help me with my problem… i need to delete a row after (left) clicking on it and then pressing the delete button on the keyboard. I can already do the part where the row catches my (left) click but after that, i don’t know how to use the delete button.. how do i do it? i also already have the code for deleting the row but I can’t call it unless I know how to call on delete. thanks! hoping for your help…thank you!

@KravvitzOct 19.2006 — I don't think there's a cross-browser way to differentiate the "." and "del" keys -- they both seem to show as 46 in JavaScript for the onkeypress event. The onkeydown and onkeyup events show different things in different browsers.

@superchritchauthorOct 19.2006 — Thanks! I used onkeyup event, however, i can't seem to pass a variable or an argument to my function. this is what i have:

//where row is the row I want to delete

function checkRow (row, event)

{

if (window.event.button == 2)

{*rightclick code*}

//left click code

else if (window.event.button == 1) {

if( document.captureEvents && event.KEYUP ) {

document.captureEvents( event.KEYUP );

}

document.onkeyup = doSomething;

}

}

function doSomething (e){

var code;

if (!e) var e = window.event;

if (e.keyCode) code = e.keyCode;

else if (e.which) code = e.which;

var character = String.fromCharCode(code);

alert('Character was ' + character);

}

this works, that is, i'm getting the keycode that i want to, but i want to also pass the row variable that i have from check row so i could do deleteRow (row.rowIndex) in doSomething but when i do this:

document.onkeyup = doSomething (row);

...

function doSomething (row, e) {

...

alert('Character was ' + character);

}

the keycode i always get is the one for left click and i don't get to press delete anymore after my alert. why is that? how do i solve this? thank you very much!

@KravvitzOct 19.2006 — Where did you get the code for the checkRow function?

document.captureEvents() is for NS4.x only. Also "event.KEYUP" should be "Event.KEYUP", if you really want to support a browser that old.
