how to load easyui-combobox data after typing 1-2 symbols

[volodias]

Hello!

I have an easyui-combobox. It's loading with PHP script and the amount of entries is ~2000.
Is it possible to let user input 1-2 leading chars and only after that to load with PHP scrips the records to the combobox? Thus, the result set will be much smaller in my case.

I have tried many combinations to pass Q parameters, but without success.

Greetings.

Hi,

Just check size in PHP and 'die' if it is too small

Hi, thanks for reply.

Yes, this should work, but maybe there is more elegant local side solution with JS?

Well, if NOT - will do this way.

The 'onBeforeLoad' event can be used to prevent from sending request to server regarding some conditions. To let users enter at least 2 chars, detect the 'q' parameter's length in 'onBeforeLoad' event.

Code:

$('#cc').combobox({
  onBeforeLoad:function(param){
    if (param.q && param.q.length<2){return false}
  }
});
