我上载了发生错误的页面。它显示在控制台中（请在Firefox或Chrome浏览器中使用F12）。
http://preventdefault.lima-city.de/index.php
这行是错误的：“ kendo.stringify（grid.getOptions（））”
我的问题：如何更改此代码，以便可以存储更改的表设置？
我也在这里插入html代码，谢谢！

最佳答案
编辑为：
您的var grid = $("#grid_one").data("kendoGrid");仅定义一次，并且定义时可能没有数据，可能在以后由kendogrid插入。Domready零件也需要引用它，您可以将其放在原始位置或将其移至function
从您和dfsq的答复来看，问题在于json无法存储函数，因此当您从localstorage检索到该函数时，必须将其添加回
在您当前的代码中，saveState将始终在setOptions之前被调用，这意味着您的saveState函数刚刚删除了saveState，因此您必须将setoptions代码向前移动。
变化很大
$(document).ready(function() {
// Get options first
var options = localStorage["kendo-grid-one"];
if (options) {
options = JSON.parse(options);
// Workaround to addback event
options.columns[6].command.click = startbuttonclick;
}
$("#grid_one").kendoGrid({
dataSource: {
data: createRandomData(10),
schema: {
.....
});
if (options) {
$("#grid_one").data("kendoGrid").setOptions(options);
}
<!-- ------------------------------------------------------------------------------ -->
function saveState(e) {
var grid = $("#grid_one").data("kendoGrid");
e.preventDefault();
localStorage["kendo-grid-one"] = kendo.stringify(grid.getOptions());
};
请参见Demo Here，现在可以使用了。
saveState部分使用dfsq可能更好options.columns[6].command.click = startbuttonclick;可以用更优雅的风格编写，但是在这里我只想说明为什么出现问题以及如何应用基本解决方案。
