How can I loop within a jQuery case statement?

I am trying to do something like this

case KEY.ATSIGN:
    while(!KEY.SPACE) {
        clearTimeout(timeout);
        timeout = setTimeout(onChange, options.delayLong);
    }
    break;

ATSIGN = 50 which is the ascii code for the @.. This invokes the autocomplete dropdown.

SPACE = 32 which is the ascii for the space character.

I need it to dropdown the autocomplete AND allow subset searching or matchCont开发者_C百科ains searching up until a space character is entered. Is this possible?

is your code like this?

switch(e.which){
  case KEY.ATSIGN : while(!KEY.SPACE){...}
}

if it is, then its wrong. when ever keypressed happen its like while(true).

try this

switch(e.which){
  case KEY.SPACE: onChange();
}

i'm not quite understand. but try this.

<input type='text' /><select>...</select>
...
$("input").keydown(function(e){
  switch(e.which){
    case KEY.ATSIGN : $(this).keyup(doSomething);
    case KEY.SPACE : $(this).unbind("keyup");
  }
})
function doSomething(){...}
