javascript - Extjs添加到组合框不可选择的="on"属性

Question

我想在组合框属性中设置unselectable="on"。我如何在javascript或jquery中做到这一点？

Ext.ux.form.HtmlEditor.HR = Ext.extend(Ext.util.Observable, {
init:function (cmp) {
    this.cmp = cmp;

    // create the combo instance
    this.combo = new Ext.form.ComboBox({
        typeAhead:true,
        enableKeyEvents:false,
        triggerAction:'all',
        lazyRender:true,
        mode:'local',
        store:[8, 10, 12, 14, 16, 18, 20, 24, 26, 28, 32, 36, 40, 48, 54, 60, 72],
        width:50,
        listeners:{
            scope:cmp,
            select:changeFont
        }

    });
    this.cmp.on('render', this.onRender, this);
},
onRender:function () {
    this.cmp.getToolbar().add(this.combo);
}

});

谢谢。

既然你使用的是 ExtJS，为什么不直接使用:

Ext.get('someElemName').unselectable();
