在编辑网格时，我需要验证数据输入，如果验证失败，我需要将坏数据恢复到未更改的状态，这样它就不会被保存（类似于使用“重置”按钮） ，但仅适用于正在编辑的当前行...这是批量编辑网格。
使用下面的javascript代码，我可以识别问题，抛出警报，但在用户接受警报后，他们仍然只需单击“保存”按钮，它就会以不正确的数据保存。
为了解决这个问题，你会看到我尝试将e.values和e.model设置为0，但它不起作用（没有抛出错误，它只是没有改变它的值网格）。
也许我需要识别DOM元素并直接更改它的值，但我无法找到如何从e对象中检索DOM元素。
function beforeCartonPackUpdates(e) {
if (e.values.QtyToPack > e.model.OrderedQty) {
alert("ERROR! You cannot pack more than was ordered.");
e.model.set("QtyToPack", 0);
e.values.QtyToPack = 0;
return false;
}
if (e.values.QtyToPack > e.model.RemainingToPack) {
alert("Warning! You are packing more than is available.");
return true;
}
}

想出来......最后很简单。只需要放入 function shipOrderDtlsGrid_OnSave(e) {
if (e.values.QtyToPack > e.model.RemainingToPack) {
e.preventDefault();
alert("ERROR! You cannot pack more than is Remaining To Pack.");
return;
}
}
