}
$('#' + target).bind("keyup",

return;
}
});
$('#' + target).bind("click",
function() {
if (defaulOption.alwaysShowALL) {

} else {
_initItems(inputChange());
}
$('#' + suggestContainerId).removeAttr("style");
var tempWidth = defaulOption.fontSize*maxFontNumber + 2 * defaulOption.itemPadding + 30;
var containerWidth = Math.max(tempWidth, suggestContainerWidth);
var h = this.scrollHeight;
$('#' + suggestContainerId).css({
'border': '1px solid #ccc',
'max-height': '100px',
'top': suggestContainerTop,
'left': suggestContainerLeft,
'width': containerWidth,
'position': 'absolute',
'font-size': defaulOption.fontSize+'px',
'font-family':'Arial',
'z-index': 99999,
'background-color': '#FFFFFF',
'overflow-y': 'auto',
'overflow-x': 'hidden',
'white-space':'nowrap'
});
$('#' + suggestContainerId).show();
});
_initItems(data);
$('#' + suggestContainerId).bind("blur",
function() {
$('#' + suggestContainerId).hide();
});
}
})(jQuery);

html如下：

select.suggest
