我有一個使用JavaScript的文本框提交功能。當腳本觸發時,它會檢查Kendo網格中的特定文章,並在其數量上添加+1,並在編輯模式下打開相應的單元格。我想實現的是,在每次提交時,啓動grid.editCell()
的計時器將重置其計時器。JavaScript clearTimeout沒有正確觸發
目前,活動正常啓動。但是,定時器不會被重置,但clearTimeout()
確實有效,如果我只是簡單地啓動定時器,然後立即清除它。
的JavaScript:
$('#txtBarcode').submit(function (e) {
var grid = $("#PickListDetailGrid").data("kendoGrid");
var dataSource = $("#PickListDetailGrid").data("kendoGrid").dataSource;
var allData = grid.dataSource.data();
var code = this.value;
var notification = $("#notification").data("kendoNotification");
var timer = null;
clearTimeout(timer);
$.each(allData, function (index, item) {
if (item.ArticleID == code) {
clearTimeout(timer);
timer = null;
if (item.Quantity > item.PickedQuantity && item.PickedQuantity.toString().length < 4) {
var edit = function() {
if (item.PickedQuantity != item.Quantity && timer != null) {
grid.select("tr:eq(" + (index) + ")");
grid.editCell("tr:eq(" + (index + 1) + ") td:eq(" + (5) + ")");
} else {
//do nothing
}
}
item.PickedQuantity++;
item.dirty = true;
dataSource.sync();
if (item.PickedQuantity != item.Quantity) {
console.log("tik tok");
if (timer) {
clearTimeout(timer); //cancel the previous timer.
timer = null;
}
timer = setTimeout(edit, 3000);
} else {
clearTimeout(timer);
timer = null;
}
document.getElementById("txtBarcode").value = "";
} else {
if (item.PickedQuantity.toString().length > 4) {
notification.hide();
notification.show({
message: "Added item"
}, "upload-success");
} else {
notification.hide();
notification.show({
title: "Quantity Error",
message: "You already picked this item to the maximum"
}, "error");
document.getElementById("txtBarcode").value = "";
grid.select("tr:eq(" + (index) + ")");
grid.editCell("tr:eq(" + (index + 1) + ") td:eq(" + (5) + ")");
$('.focus :input').focus();
}
}
}
})
})
爲什麼?這是如何解決這個問題的? –
