我正在尝试在多个jQuery Ajax 完成之后执行回调
在我的代码中,两个Ajax请求都调用另一个函数,当我尝试使用这些函数时,我得到undefined
我认为问题与使用延迟/承诺有关,但我不知道如何使用它们。
这是我的代码:
<link rel="stylesheet" type="text/css" href="https://tag/sites/ocean1/maker/captions/shared%20documents/Web_ComplianceCSS.txt">
<div id = "cabbage" style="font-size:10px">
<p>Web Compliance Stats</p>
</div>
<script type = "text/javascript">
var WebComplianceReportApp = {} || WebComplianceReportApp;
WebComplianceReportApp.GetStatuses = (function() {
var pub = {},
_userId,
_ultimateObjectHolderArr = [],
_items = [],
_options = {
listName: "M_Web_Compliance",
container: "#cabbage",
};
pub.init = function() {
var clientContext = new SP.ClientContext.get_current();
_userId = clientContext.get_web().get_currentUser();
clientContext.load(_userId);
clientContext.executeQueryAsync(getUserInfo, _onQueryFailed);
};
function getUserInfo() {
_userId = _userId.get_id();
getSpecifiedList(_options.listName, _userId);
}
function buildObject(results, listName) {
_items = results.d.results;
$.each(_items, function(index, item) {
_ultimateObjectHolderArr.push({
"Division": item.ParentOrg,
"ORG": item.ORG,
"URL": item.URL,
"Status": item.Site_Status
});
});
//createStatusView2(_ultimateObjectHolderArr);
}
function getSpecifiedList(listName, userId) {
var counter = 0;
var baseUrl = SP.PageContextInfo.get_webServerRelativeUrl() + "/_vti_bin/listdata.svc/" + listName;
var url1 = baseUrl + "?$select=ParentOrg,ORG,URL,Site_Status&$inlinecount=allpages";
var call1 = $.ajax({
url: url1,
type: "GET",
headers: {
"accept": "application/json;odata=verbose",
}
}).done(function(results) {
buildObject(results, listName);
}).fail(function(error) {
console.log("Error in getting List: " + listName);
$(_options.container).html("Error retrieving your " + listName + ". " + SP.PageContextInfo.get_webServerRelativeUrl());
});
var url2 = baseUrl + "?$select=ParentOrg,ORG,URL,Site_Status&$inlinecount=allpages&$skiptoken=1000";
var call2 = $.ajax({
url: url2,
type: "GET",
headers: {
"accept": "application/json;odata=verbose",
}
}).done(function(results) {
buildObject(results, listName);
}).fail(function(error) {
console.log("Error in getting List: " + listName);
$(_options.container).html("Error retrieving your " + listName + ". " + SP.PageContextInfo.get_webServerRelativeUrl());
});
}
function createStatusView2(Arr) {
var divisionArr = [];
var oRGArr = [];
var divisionCount = 0;
var oRGCount = 0;
for (var i = 0; i < Arr.length; i++) {
if ($.inArray(Arr[i].Division, divisionArr) === -1) {
divisionArr.push(Arr[i].Division);
var divisionHolderElement = $("<div id='p_" + Arr[i].Division + "' class='division_row_holder'></div>");
var divisionElement = $("<div id='" + Arr[i].Division + "' class='division_div ORG'></div>").text(Arr[i].Division);
$("#cabbage").append(divisionHolderElement);
$(divisionHolderElement).append(divisionElement);
}
if ($.inArray(Arr[i].ORG, oRGArr) === -1) {
oRGArr.push(Arr[i].ORG);
var orgElement = $("<div class='org_div ORG' id='" + Arr[i].ORG + "' style='font-size:10px;'></div>").text(Arr[i].ORG);
$("#p_" + Arr[i].Division).append(orgElement);
}
}
}
//automatically fired by init
function _onQueryFailed(sender, args) {
alert('Request failed.\nError: ' + args.get_message() + '\nStackTrace: ' + args.get_stackTrace());
}
return pub
}());
$(document).ready(function() {
SP.SOD.executeFunc('sp.js', 'SP.ClientContext', function() {
//After the SP scripts are run, we access the WebComplianceReportApp.GetStatuses
WebComplianceReportApp.GetStatuses.init();
});
});
</script>

您可以调用createStatusView();
,然后在完成所有Ajax请求后调用createStatusView2();
$(document).ready(function(){
createStatusView();
$(this).ajaxStop(function() {
// NOTE: I did not see you use createStatusView(); in your code
createStatusView2();
});
});

这次我们等待完成的请求,而不是等待成功的请求
$(".ajax-form-button-thingy").on("click", function() {
$.ajax({
url: $(this).attr("href"),
type: 'GET',
error: function() {
throw new Error("Oh no, something went wrong :(");
},
complete: function(response) {
$(".ajax-form-response-place").html(response);
}
});
});
如果您想等待所有 Ajax请求完成而不将async
选项更改为false
,那么您可能正在寻找jQuery.ajaxComplete();
在jQuery中,每次Ajax请求完成时,都会触发jQuery.ajaxComplete();
事件。
以下是一个简单的示例,但jQuery.ajaxComplete();
超过here的信息更多。
$(document).ajaxComplete(function(event, request, settings) {
$(".message").html("<div class='alert alert-info'>Request Complete.</div>");
});
您还可以使用request.responseText
来查看Ajax响应,如果您想要仔细检查响应,这可能很有用。

我不知道这是否会使你的代码变脏,但在这种情况下我会使用标志
<强>例如:强>
var ajaxCalls = 0;
function checkAjaxCalls()
{
if (ajaxCalls == 2)
{
//do your thing...
//and maybe you want to reset ajaxCalls value to zero if needed...
}
}
从每个Ajax响应完成后,将ajaxCalls
变量递增1,并从两个Ajax响应中调用checkAjaxCalls
函数。
