Ext GridPanel實(shí)現(xiàn)復(fù)選框選擇框:
1 var selectModel = new Ext.grid.CheckboxSelectionModel({
2 singleSelect : false
3 });
4
但是這樣每一行都會(huì)有復(fù)選框,如果需求為:某行數(shù)據(jù)的某個(gè)列滿足什么條件我才有復(fù)選框選項(xiàng)就不太好實(shí)現(xiàn)了,
這樣就需要重寫Ext.grid.CheckboxSelectionModel的渲染,行點(diǎn)擊涵數(shù)來實(shí)現(xiàn).
1 var selectModel = new Ext.grid.CheckboxSelectionModel({
2 singleSelect : false,
3 renderer : function(v, p, record){
4 if (record.data['結(jié)果狀態(tài)'] == '0'){
5 return '';
6 }
7 return '<div class="x-grid3-row-checker"> </div>';
8 },
9 onHdMouseDown : function(e, t) {
10 if (t.className == 'x-grid3-hd-checker') {
11 e.stopEvent();
12 var hd = Ext.fly(t.parentNode);
13 var isChecked = hd.hasClass('x-grid3-hd-checker-on');
14 if (isChecked){
15 hd.removeClass('x-grid3-hd-checker-on');
16 this.clearSelections();
17 }else {
18 hd.addClass('x-grid3-hd-checker-on');
19 if (this.locked){
20 return;
21 }
22 this.selections.clear();
23 for (var i = 0, len = this.grid.store.getCount(); i < len; i++ ){
24 if (this.grid.store.getAt(i).data["結(jié)果狀態(tài)"] != '0'){
25 this.selectRow(i, true);
26 }
27 }
28 }
29 }
30 },
31 handleMouseDown : function(g, rowIndex, e){
32 if (e.button !== 0 || this.isLocked()) {
33 return;
34 }
35 var view = this.grid.getView();
36 if (e.shiftKey && !this.singleSelect && this.last != false ) {
37 var last = this.last;
38 this.selectRange(last, rowIndex, e.ctrlKey);

43 if (e.ctrlKey && isSelected) {
44 this.deselectRow(rowIndex);
45 }else if(!isSelected || this.getCount() > 1){
46 if(this.grid.store.getAt(rowIndex).data["結(jié)果狀態(tài)"] != '0'){
