获取单击的JSON元素';使用ExtJS的s值
我有一个JSON存储:获取单击的JSON元素';使用ExtJS的s值,json,extjs,nodes,Json,Extjs,Nodes,我有一个JSON存储: var jsonstore = new Ext.data.ArrayStore({ fields: ['bla', 'blubb'], data: [ ['bla', 'blubb'], ['blabla', 'blublu'], ['blass', 'hallo'], ['bam', 'guckt'] ] }); 和一个extjs列表视图: .... ,{ xtype
var jsonstore = new Ext.data.ArrayStore({
fields: ['bla', 'blubb'],
data: [ ['bla', 'blubb'],
['blabla', 'blublu'],
['blass', 'hallo'],
['bam', 'guckt'] ]
});
和一个extjs列表视图:
....
,{
xtype: 'listview',
name: 'abrufliste',
store: jsonstore,
id:"ladebereich",
multiSelect: false,
emptyText: 'nix da',
reserveScrollOffset: true,
columns: [ { header: 'Name',
width: .5,
dataIndex: 'NAME' }
....
,{
xtype: 'listview',
name: 'abrufliste',
store: jsonstore,
id:"ladebereich",
multiSelect: false,
emptyText: 'nix da',
reserveScrollOffset: true,
listeners:
{
click: function(object, selectedIndex, node, event) {
// Get the name corresponding to the selected row.
var rowName = object.store.getAt(selectedIndex).get("Name");
}
},
columns: [ { header: 'Name',
width: .5,
dataIndex: 'NAME' }
和单击事件:
Ext.ComponentMgr.get('ladebereich').on("click",function (sthis,index,node,e ){
alert("node: "+node.childNodes[0].childNodes[0].innerHTML);});
我想获取单击的节点的值
我确实得到了它的价值
node.childNodes[0].childNodes[0].innerHTML
然而,这是一个糟糕的解决方案
我想从我的jsonstore中获取单击的元素,
有什么建议吗?它与
Ext.ComponentMgr.get('ladebereich').on("click",function (sthis,index,node,e ){
var rec = jsonstore.getAt(index);
alert(rec.get("NAME"));
});
另一种方法是向listview添加侦听器,以响应listview上的任何单击事件:
....
,{
xtype: 'listview',
name: 'abrufliste',
store: jsonstore,
id:"ladebereich",
multiSelect: false,
emptyText: 'nix da',
reserveScrollOffset: true,
columns: [ { header: 'Name',
width: .5,
dataIndex: 'NAME' }
....
,{
xtype: 'listview',
name: 'abrufliste',
store: jsonstore,
id:"ladebereich",
multiSelect: false,
emptyText: 'nix da',
reserveScrollOffset: true,
listeners:
{
click: function(object, selectedIndex, node, event) {
// Get the name corresponding to the selected row.
var rowName = object.store.getAt(selectedIndex).get("Name");
}
},
columns: [ { header: 'Name',
width: .5,
dataIndex: 'NAME' }
