只要是component都可以用plugins
plugin必须含有init方法
使用插件:
var checkColumn = new Ext.grid.CheckColumn({//生成一个
header: "Indoor?",
dataIndex: 'indoor',
width: 55
});
new Ext.grid.EditorGridPanel({
store: store,
cm: cm,
renderTo: 'editor-grid',
width:600,
height:300,
autoExpandColumn:'common',
title:'Edit Plants?',
frame:true,
plugins:checkColumn,//**********列举要使用的插件
clicksToEdit:1});
var cm = new Ext.grid.ColumnModel([{
id:'common',
header: "Common Name",
dataIndex: 'common',
width: 220,
editor: new fm.TextField({
allowBlank: false
})
},
checkColumn//使用插件
]);
自定义插件(即自定义一个包含init()方法 的类),这里是定义一个和CheckBox类似的东西,有很多处我没看懂
Ext.grid.CheckColumn = function(config){
Ext.apply(this, config);
if(!this.id){
this.id = Ext.id();
}
this.renderer = this.renderer.createDelegate(this);
};
Ext.grid.CheckColumn.prototype ={
init : function(grid){
this.grid = grid;
this.grid.on('render', function(){
var view = this.grid.getView();
view.mainBody.on('mousedown', this.onMouseDown, this);
}, this);
},
onMouseDown : function(e, t){
if(t.className && t.className.indexOf('x-grid3-cc-'+this.id) != -1){
e.stopEvent();
var index = this.grid.getView().findRowIndex(t);
var record = this.grid.store.getAt(index);
record.set(this.dataIndex, !record.data[this.dataIndex]);
}
},
renderer : function(v, p, record){
p.css += ' x-grid3-check-col-td';
return '<div class="x-grid3-check-col'+(v?'-on':'')+' x-grid3-cc-'+this.id+'"> </div>';
}
