我有一个代码循环,可以为弹出模式添加选项,每个选项旁边都有按钮。
在搜索循环中,有时当搜索返回多个项目时,我们必须显示模态,用户选择哪个部分。
我想暂停循环并等待用户选择一个项目,然后再继续。
MY LOOP
$.each(rows, function (index, item) {
SearchItems(item.split('\t')[0], item.split('\t')[1]);
});
搜索项目功能
function SearchItems(searchedPart, quantity) {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "OrderFormServices.asmx/GetItemInfoAdmin",
data: "{'itemname':'" + searchedPart + "','quantity':'" + (quantity || 1) + "', 'guid':'" + custGuid + "' }",
dataType: "json",
success: function (result) {
result = result.d;
if (result.length > 1) {
var htmlString = "";
$.each(result, function(index, item) {
item.PartNumber = (item.PartNumber != "") ? item.PartNumber : item.ItemName;
htmlString += "<tr><td>"
+ "<input type=\"hidden\" name=\"ItemID\" value=\"" + item.ItemID + "\">"
+ "<input type=\"hidden\" name=\"ItemCode\" value=\"" + item.ItemCode + "\">"
+ "<input type=\"hidden\" name=\"Price\" value=\"" + item.Price + "\">"
+ "<input type=\"hidden\" name=\"Quantity\" value=\"" + item.Quantity + "\">"
+ "<input type=\"hidden\" name=\"CustomerReference\" value=\"" + searchedPart + "\">"
+ "<input type=\"hidden\" name=\"PackQuantity\" value=\"" + item.PackQuantity + "\">"
+ "<input type=\"hidden\" name=\"FreeStock\" value=\"" + item.FreeStock + "\">"
+ item.PartNumber + "</td><td>"
+ item.ManufacturerName + "</td><td>"
+ item.ItemName + "</td><td>"
+ item.ItemDescription + "</td><td><input type='button' name=\"selectPopup\" onclick=\"ChoosePopup($(this).closest('tr'));\" class='btn btn-primary btn-xs' value='Select'></td></tr>";
});
$("#tbodyPopupContent").html(htmlString);
$("#PopUpNormalProduct").modal();
modalfix();
$("#divPopupWindow").parent("").addClass("quicksearchpopup");
//////////////////////////////////////////////////////////////////////////
//////////////// WAIT FOR BUTTON CLICK AND PERFORM CODE///////////////////

$("#partNumber").prop("disabled", false);
} else if (result.length < 1) {
$("#partNumber").prop("disabled", false);
$('#partNumber').focus();
}
else {
///////
}
}
});
}
弹出项目按钮触发ChoosePopup()
功能。
function ChoosePopup(row) {
var $hidden_fields = row.find("input:hidden");
var $tds = row.find("td");
var newItem = {
ItemID: parseFloat($hidden_fields.eq(0).val()),
ItemCode: $hidden_fields.eq(1).val(),
ItemDescription: $tds.eq(3).text(),
ItemName: $tds.eq(2).text(),
Price: parseFloat($hidden_fields.eq(2).val()),
Quantity: parseFloat($hidden_fields.eq(3).val()),
CustomerReference: $hidden_fields.eq(4).val(),
PackQuantity: parseFloat($hidden_fields.eq(5).val()),
FreeStock: parseFloat($hidden_fields.eq(6).val())
};
AddNewRow(newItem, true);
$("#PopUpNormalProduct").modal("hide");
}
在继续循环之前,如何等待此ChoosePopup()
函数完成?

定义全局变量并根据弹出的请求,将其余代码移到ChoosePopup()函数。

我认为你应该重新思考你接近问题的方式。您应该使用回调激活ChoosePopup函数,以根据用户输入执行其余工作。
您可以考虑将rows数组传递给SearchItems函数,以便您可以设置回调以遍历行中的其余项。
这是一个不需要重复代码的示例。
SELECT Gender, COUNT(*) AS "Number of employees", Age
FROM Employee
WHERE year(column_name) >= 1999 --Give a real date column here
GROUP BY Age, Gender
const items = [1, 2, 3, 4, 5]
//main function which writes buttons from an array
function makeButtons(array) {
//copy the array so we can keep track of which items are left to process after click event
var unProcItems = array.slice()
$.each(array, function(index, item) {
var exit = false
//remove the item from the processed array
unProcItems.splice(unProcItems.indexOf(item), 1)
//make our button
var button = document.createElement('button')
button.innerHTML = `Button ${item}`
//if something then hook up a click event with callback
if (item == 3) {
button.onclick = function(event) {
//call our makeButtons function in the callback passing in the unprocessed items array
makeButtons(unProcItems)
//remove the click event so it can't be fired again
event.target.onclick = null
}
exit = true
}
document.getElementById('content').append(button)
//exit the loop if our flag was set
if (exit)
return false;
})
}
makeButtons(items);
