即時使用extjs3。我的問題是使用ajax從服務器端加載商店。如下當在網格中檢查多行時，Ext.grid.CheckboxSelectionModel沒有返回正確的id值
var store_dept = new Ext.data.JsonStore({
totalProperty:'totalcount',
root:'rows_dept',
autoLoad:true,
url: '<%=getResultURL.toString()%>',
fields:[
{ name:'name'},
{ name:'id'},
{ name:'address'}
]
});
var sm_dept = new Ext.grid.CheckboxSelectionModel(
{
singleSelect: false,
checkOnly: false,
listeners: {
selectionchange: function(sm_dept) {
}
}
}
);
現在即時得到這樣的IM格式化渲染器列
function renderBufferResult_dept(value, p, record){
return String.format('<div style="white-space:normal !important;"><b>{1}</b><br/>{3}<br/>{2}<br/></div>',value,record.data.name,record.data.address,record.data.id);
}
電網碼的響應是：
var grid_dept= new Ext.grid.GridPanel({
id:'resgriddept',
width:210,
height:300,
title:'Additional Notification',
store: store_dept,
trackMouseOver:false,
disableSelection:true,
loadMask: true,
sm:sm_dept,
// grid columns
columns:[
sm_dept,
{
header: "Details",
dataIndex: 'id',
width:210,
sortable: true,
renderer:renderBufferResult_dept
}
] ,
buttons: [
{
text:'Export To Excel',
handler: function()
{
if(property_list!=''){
/* var prop_list='';
for(var i=0 ;i<sm.selections.getCount();i++){
prop_list =prop_list+ sm.selections.get(i).data.id+',';
} */
window.open('<%=getxlFileURL%>'+'&id_list='+property_list);
}else{
alert('Select propert to Export');
}
}
},{
text:'Generate Letter',
handler: function()
{
var dept_id_list = '0,';
if(sm_dept.selections.getCount()>0){
alert('cont select');
for(var j=0 ;j<sm_dept.selections.getCount();j++){
alert("id "+sm_dept.selections.get(j).data.id);
dept_id_list = dept_id_list+sm_dept.selections.get(j).data.id+',';
alert('id with templist '+dept_id_list);
}
}
window.open('<%=getreportsURL%>'+'&id_list='+property_list+'&dept_id_list='+dept_id_list);
}
}],
buttonAlign:'center'
});//End Of Grid
// render it
grid_dept.render('res-grid-dept');
store_dept.load();
問題是當我打生成字母鍵，被檢查的行（1,2,3）的id就像0,1,1,2，當它在警報中必須像0,1,2,3一樣。
