There are 3 ways to set the height of inputing components.
1. Override the CSS style.
.textbox .textbox-text{
height: 22px;
box-sizing:border-box;
}
2. Override the $.fn.textbox.default.height.
<script type="text/javascript">
$.fn.textbox.defaults.height = 22;
$.fn.numberbox.defaults.height = 22;
//...
</script>
3. Set the inline height style.
<input class="easyui-textbox" style="width:100%;height:22px">
