作爲一名設計師，當沒有數據可以讓人失望的時候，我就會對美麗的「空白狀態」信息產生興趣，鼓勵用戶採取行動。 （事實上，是一個整體的tumblr博客獻給這樣的：http://emptystat.es/）有沒有辦法使用Flexigrid顯示有吸引力的「空狀態」消息？
由於Flexigrid的快樂和忠誠的用戶，我很想能夠代替空狀態消息時，系統我建立沒有任何搜索結果要顯示在網格中（例如「您沒有待處理的請求！單擊新建開始」）。理想情況下，這樣一個空狀態的消息將是圖形和比單獨的行大，並將取代網格的全部內容。任何人都可以提供一些建議，關於如何在沒有行返回時使用圖形空狀態消息替換flexigrid的內容？
謝謝！

我使用dojo解決了這個問題，因爲我們已經在我們的網站中使用這個框架。我確信在不同的圖書館中有類似的解決方案。基本上我創建了一個新的類，創建flexigrid後，通知如果在flexigrid沒有數據，如果指定了一個放在一個背景圖像表：
dojo.provide("app.components.EmptyStateFlexigrid");
dojo.require("dijit._Widget");
// Provides a custom Flexigrid with an empty-state
dojo.declare("app.components.EmptyStateFlexigrid", [dijit._Widget], {
emptyStateUrl: null,
id: null,
url: null,
colModel: null,
buttons: null,
sortField: null,
sortOrder: null,
height: null,
usePager: null,
resizable: null,
// Create the flexigrid object
makeGrid: function() {
var gridObj = $('#' + this.id + "_flexigrid");
gridObj.flexigrid({
url: this.url,
dataType : 'json',
colModel : this.colModel,
buttons : this.buttons,
sortname : this.sortField,
sortorder : this.sortOrder,
height: this.height,
usepager : this.usePager,
resizable: this.resizable,
onSuccess: this.checkEmptyState,
useRp : true,
rpOptions: [2, 10, 15, 20, 30, 50],
rp : 15,
showTableToggleBtn : false
});
}
},
// EMPTY-STATE: make a nice graphic here if there is no data
// Note that "this" is a flexigrid object
checkEmptyState: function() {
var self = dijit.byId(this.id);
var gridObj = $('#' + this.id + "_flexigrid");
if (gridObj[0].id === this.id + '_flexigrid') {
var gridChildren = gridObj.children();
if (gridChildren.length === 0) {
var gblocks = $(".gBlock");
for (var i = 0; i < gblocks.length; i++) {
var styleObj = gblocks[i].style;
// The only way I could find to identify "our" flexigrid (if there is
// more than one on the page) is to test to see if the height is the
// same as our height. Kind of a lousy hack, but the best I could figure
// out. -pbanka
if (styleObj.height == self.height + 'px') {
styleObj.backgroundSize = "450px";
styleObj.backgroundRepeat = "no-repeat";
styleObj.backgroundImage = "url('" + self.emptyStateUrl + "')";
}
}
}
}
},
對不起，我想我沒」在我原來的問題中非常明確。我正在尋找一個專門涉及Flexigrid jQuery數據網格對象的解決方案，如下所示：http://flexigrid.info/ – pbanka
是的，這就是我所提到的。您應該將flexgrid與HTML表關聯起來。 Flexigrid將修改各種表格屬性並添加一些裝飾以使其有用。然後，您可以使用經典的Javascript或jQuery控制關聯的HTML表格。使用table.innerHTML將其更改爲任何你想要的。 – exebook
