我有一个包含五列的网格 - 用户名,电子邮件,启用,锁定和删除。
用户名,电子邮件,已启用和已锁定均来自服务器。 Remove是一个客户端元素,用于指示应该删除一行。
我想在网格内容加载时在客户端的商店中注入remove的默认值,或者在用户与CheckBox小部件交互时将其设置为。
如何捕获从服务器请求对象并添加其他列的代码?
或者,有没有更好的方法来做到这一点。
var TrackableRest = declare([Rest, SimpleQuery, Trackable]);
var store = new TrackableRest({target: '/api/users', useRangeHeaders: true, idProperty: 'username'});
aspect.after(store, "fetch", function (deferred) {
return deferred.then(function (response) {
response.remove = false;
return json(response);
})
});
var grid = new (declare([OnDemandGrid, Selection, Editor]))({
collection: store,
className: "dgrid-autoheight",
columns: {
username: {
label: core.username
},
email: {
label: core.email
},
enabled: {
label: core.enabled,
editor: CheckBox,
editOn: "click",
sortable: false,
renderCell: libGrid.renderGridCheckbox
},
locked: {
label: core.locked,
editor: CheckBox,
editOn: "click",
sortable: false,
renderCell: libGrid.renderGridCheckbox
},
remove: {
editor: CheckBox,
editorArgs: {"checked": false},
editOn: "click",
label: core.remove,
sortable: false,
className: "remove-cb",
renderHeaderCell: function (node) {
var inp = domConstruct.create("input", {id: "cb-all", type: "checkbox"});
return inp;
},
renderCell: libGrid.renderGridCheckbox
}
},
selectionMode: "none"
}, 'grid');
此外,我不想将删除列发送到服务器。
答案 0 :(得分:0)
我的最终实现是对remove列进行编码,如下所示:
remove: {
editor: CheckBox,
label: core.remove,
sortable: false,
className: "remove-cb",
renderHeaderCell: function (node) {
var inp = domConstruct.create("input", {id: "cb-all", type: "checkbox"});
return inp;
}
}
执行删除的代码如下:
var removeBtn = new Button({
label: core.remove
}, 'user-remove-btn');
removeBtn.startup();
removeBtn.on("click", function (event) {
var markedForDeletion = query(".dgrid-row .remove-cb input:checked", "user-grid");
if( markedForDeletion.length > 0 ) {
lib.confirmAction(core.areyousure, function () {
markedForDeletion.forEach(function (node) {
var row = grid.row(node);
store.remove(row.data.username);
});
});
}
});
因此,删除列成为仅由客户端控制的,由网格和事件处理程序处理。
