我完成的效果是:
这里点击左边的树是联动右边itemselector 组件中的用户,并且带有用户搜索
一:废话不多,贴上js代码:
var addUsersWin,addUsersFun = function (data) { userSelectStore.load(); userSelectStoreOwn.load(); addUsersWin = new Ext.Window({ title:"添加员工", width:780, height:480, buttonAlign:'center', modal:true, items:[ { xtype:'form', plain:true, url:'system/addOrganizationUser.json', labelWidth:80, baseCls:"x-plain", bodyStyle:"padding:8px", labelAlign:'right', frame: true, items: [{ layout:'column', height:50, border :false, bodyCssClass : "queryForm", defaults : { layout : 'form', border :false, bodyCssClass: "queryForm", defaults : { anchor : '95%', xtype : "textfield" } }, items:[ { columnWidth:0.7, //layout: 'form', items: [{ xtype:'textfield', name: "filter['name']", id:'userName', fieldLabel: '用户姓名' }] }, { columnWidth:0.08, //layout: 'form', items: [ { xtype:'button', text: '查询', iconCls: 'findItem', handler: function(){ var un= Ext.getCmp('userName').getValue(); userSelectStore.baseParams={ name:un }; userSelectStore.load(); } } ] } ] },{ layout:'column', height:300, items:[ { columnWidth:0.3, layout: 'form', items: [{ xtype:'treepanel', region: 'west', split: true, width: 200, height: 300, margins:'0 4 0 0', enableDD: true, containerScroll: true, border: false, rootVisible: false, autoScroll:true, root: { nodeType: 'async' }, loader: new Ext.tree.TreeLoader({ dataUrl: 'system/organization/resourceTree.json?type=1', baseAttrs: {uiProvider: Ext.ux.TreeCheckNodeUI} }), listeners: { checkchange: function(node, checked){ node.expand(); node.attributes.checked = checked; node.eachChild(function(child) { child.ui.toggleCheck(checked); child.attributes.checked = checked; child.fireEvent('checkchange', child, checked); }) }, afterRender: function (t) { treeP = t; treeP.root.expand(true); }, click:function(node){ if(node.id!='root'){ userSelectStore.baseParams={ id:node.id }; userSelectStore.load(); } } } }] }, { columnWidth:0.7, layout: 'form', items: [ { xtype:'itemselector', name:'userIds', imagePath:'images/ext/ux/images/', availableTitle:'可选用户', selectedTitle:'已选用户', multiselects:[ { width:200, height:300, store:userSelectStore, displayField:'name', valueField:'id' }, { width:200, height:300, displayField:'name', valueField:'id', store:userSelectStoreOwn } ] } ] } ] } ] } ], buttons:[ { text:'确定', handler:function () { var fromPanel = addUsersWin.get(0); if (!fromPanel.getForm().isValid()) { Ext.Msg.alert("提示", "请按相关提示正确填写"); return; } fromPanel.form.submit({ params:{id:data.id}, waitMsg:'正在处理中...', failure:function (form, action) { Ext.Msg.alert('错误消息', "修改失败,请联系技术人员!"); }, success:function (form, action) { Ext.MessageBox.alert('消息提示', '添加成功!'); frameworkGridStore.reload(); addUsersWin.destroy(); } }); } }, { text:'取消', handler:function () { addUsersWin.destroy(); } } ] }); addUsersWin.show(); }二:这里我们先看表单中, xtype:'itemselector',组件,要用到,需要引入两个js:
和
这样 itemselector组件就可以用了,其中左边加载的数据:可选用户:userSelectStore
var userSelectStore = new Ext.data.JsonStore({ url:'system/getAllUserList.json', idProperty:'id', fields:[ 'id', 'name' ], root:'userList', paramNames : { id:'', name:'' } });右边部分加载的数据:已选用户:userSelectStoreOwn
var userSelectStoreOwn = new Ext.data.JsonStore({ url:'system/getOrganizationUserList.json', idProperty:'id', fields:[ 'id', 'name' ], root:'userList' });三:接着我们来看一下整个window弹出窗中,左边treePanel的绑定的事件:
click:function(node){ if(node.id!='root'){ userSelectStore.baseParams={ id:node.id }; userSelectStore.load(); } }通过 click事件,我们可以根据树节点的 id去加载 itemselector组件左边,可选用户的数据.
四:最后,我们在做搜索的时候:
xtype:'button',
text: '查询',
iconCls: 'findItem',
handler: function(){
var un= Ext.getCmp('userName').getValue();
userSelectStore.baseParams={
name:un
};
userSelectStore.load();
}
我们是把输入框input中的值作为itemselector左边可选用户的数据加载的参数,去加载可选用户。
五:最后说一下itemselector这个组件,在表单中是通过name:'userIds',把多个的id的字符串传给java后台的,处理时候,只要切割逗号的字符串,就行了。这个组件的js目前只封装好了,传valueField的值过去,
如果想要显示值是displayField,要在源码中自己仿照getValue()方法写获得displayField的方法。
好了,这里主要是介绍extjs代码的处理,后台java的代码就不贴了。
