extjs4——去掉combobox跟tree的loadMask

extjs4——去掉combobox和tree的loadMask

设置combobox的store的query项为remote时，点击 combobox的下拉列表时，会实时发ajax请求去load数据，这时默认会出现loadmask。

 

 

/* remove loadMask for combobox load */
Ext.form.field.ComboBox.prototype.defaultListConfig={
        emptyText: '',
        //loadingText: 'Loading...', //remove this
        //loadingHeight: 70,    //remove this
        loadMask:false,   //add this
        minWidth: 70,
        maxHeight: 300,
        shadow: 'sides'
};

 

同理, treepanel的store，也可以去掉loadMask:

 

Ext.create('Ext.tree.Panel', {
            store: treeConfig.store,
            cls:'x-column-tree',
            rootVisible: false,
            viewConfig: {
                loadMask: false, //remove loadMask
                plugins: {
                    ptype: 'treeviewdragdrop'
                }
            },
            autoHeight:true,
            height:'900',
            width: 250,
            title: '',
            useArrows: true,
            border:false
        });
