首先，您的getFormDigest功能不太正確：
function getFormDigest(baseurl) {
// you pass in a "baseurl" value above, but you're not really doing anything with it.
// the URL you use below is hardcoded to always
// make the request to the /sites/Projects/USMC/AMMO site
return $.ajax({
url: "https://baseurl.sharepoint.com/sites/Projects/USMC/AMMO/_api/contextInfo",
method: 'POST',
headers: {
'Accept': 'application/json; odata=verbose'
}
});
}
您需要做的是更改它，以便您可以將站點(diǎn) URL 傳遞給它并從您嘗試將新項(xiàng)目發(fā)布到的實(shí)際站點(diǎn)獲取有效的表單摘要：
function getFormDigest(siteUrl) {
return $.ajax({
url: siteUrl + "/_api/contextInfo",
method: 'POST',
headers: {
'Accept': 'application/json; odata=verbose'
}
});
}
接下來(lái)，您需要更改您的PostItem函數(shù)以對(duì)所選程序的當(dāng)前值做出反應(yīng)，并根據(jù)該值選擇一些正確的值。我在評(píng)論中看到您發(fā)布了一個(gè)小片段，您正在創(chuàng)建一個(gè)地圖，該地圖將根據(jù)所選程序的密鑰吐出正確的 URL。如果您只需要一個(gè)值，那是可行的，但是，由于您說(shuō)過(guò)每個(gè)子站點(diǎn)上的列表名稱(chēng)都不同，因此您實(shí)際上需要根據(jù)所選程序動(dòng)態(tài)生成三個(gè)不同的值：
站點(diǎn)本身的 URL，以便您可以獲得有效的表單摘要，
列表名稱(chēng)，以便您可以為新項(xiàng)目的 JSON__metadata屬性獲取正確的列表項(xiàng)目實(shí)體類(lèi)型值。您有執(zhí)行此操作的功能，但您沒(méi)有使用它。此外，您還需要列表名稱(chēng)：
一個(gè)包含站點(diǎn)和列表名稱(chēng)的URL ，以便您可以發(fā)布新的列表項(xiàng)（因?yàn)檫@樣做的 URL 本質(zhì)上是[URL to site]/_api/web/lists/getbytitle('[list name]')/items）
您可以執(zhí)行一系列if..then..else if..then..else if..then..else語(yǔ)句，但是對(duì)于超過(guò)兩個(gè)或三個(gè)可能的值，這會(huì)變得很麻煩。一種更簡(jiǎn)潔的方法是使用語(yǔ)句switch。因此，PostItem如果您使用 aswitch來(lái)評(píng)估所選程序值是什么，然后基于該值動(dòng)態(tài)設(shè)置站點(diǎn) URL 和列表名稱(chēng)，那么您的函數(shù)可能如下所示：
function PostItem() {
// the base URL should be what is the same across all subsites. in comments
// you said the subsites start to differ after /sites/Projects.
var baseUrl = "https://your-tenant.sharepoint.com/sites/Projects";
// get the selected program from your form
var programName = $("#dProgram").val();
var siteUrl = null; // set this as empty for now
var listName = null; // set this as empty for now
// a "switch" statement is like a fancy "if" statement that is
// useful if you have more than just two or three options
switch (programName) {
case "AMMO":
// set the site url to be whatever it is after /sites/Projects.
// in the case of AMMO, you have already posted that the "AMMO"
// subsite is under a "USMC" subsite that is under "Projects"
siteUrl = baseUrl + "/USMC/AMMO";
listName = "AMMODeliverables";
break;
case "AHR":
// set the site url to be whatever it is after /sites/Projects.
// IF in this case the "AHR" subsite is directly under /Projects
// and NOT under another subsite (as is the case with /USMC/AMMO),
// you just add that directly:
siteUrl = baseUrl + "/AHR";
// HOWEVER, if it is under another subsite with a different name, similar
// to how "AMMO" is actually under another subsite called "USMC", then you
// would include that "Other" subsite here:
siteUrl = baseurl + "/Other/AHR";
// set the list name, since you said the list names
// are different in each of the subsites
listName = "AHR Deliverables";
break;
case "FOO":
// pretending that "FOO" is _directly_ under /sites/Projects
siteUrl = baseurl + "/FOO";
listName = "FOO Thingys";
break;
case "BAR":
// pretending that "BAR" is NOT directly under /sites/Projects,
// but is in fact under another "Different" subsite
siteUrl = baseurl + "/Different/BAR";
listName = "BAR Whatchamacallits";
default:
// all switch statements need a default option in case
// what we are checking does not match any any of the options
// we are expecting. in this instance, we will _not_ set
// a site URL or list name so that we do not try to post
// to s non-existent site or list
break;
}
// if we didn't get one of our expected choices for programName, then siteUrl
// will not have been populated in the switch, so we can check and make sure we
// actually have a valid siteUrl before we start sending AJAX requests out
if (siteUrl) {
// pass the siteUrl into your improved getFormDigest function so
// that you get the correct form digest from the site you are
// actually trying to post a new item to.
// also, you don't actuall need the "return" here.
getFormDigest(siteUrl).then(function(digestData) {
console.log(digestData.d.GetContextWebInformation.FormDigestValue);
// use your getItemTypeForListName function to get the
// correct SharePoint List Item Entity Type name based on
// the list name
var listItemEntityType = getItemTypeForListName(listName);
// construct the URL to post the new list item to based on the siteUrl
// and the listName, which vary based on the selected projecName
var postNewItemUrl = siteUrl + "/_api/web/lists/getbytitle('" + listName + "')/items";
// construct your new item JSON. you said all the fields
// in all the lists are the same, so the only thing that really
// needs to dynamically chage here is the entity type name,
// which was generated based on the list name
var item = {
"__metadata": { "type": listItemEntityType },
"Title": "updated title",
"Program": programName,
"Deliverable": $("#dDeliverable").val(),
"To": $("#dTo").val(),
"Date": $("#dDate").val(),
"Approved": $("#dApproved").val(),
"Notes": $("#dNotes").val()
};
$.ajax({
// use your dynamically generated URL here
url: postNewItemUrl,
method: "POST", //Specifies the operation to create the list item
data: JSON.stringify(item),
headers: {
"content-type": "application/json;odata=verbose",
"X-RequestDigest": digestData.d.GetContextWebInformation.FormDigestValue,
"Accept": "application/json;odata=verbose",
"If-Match": "*"
},
success: function(data) {
alert('Success'); // Used sweet alert for success message
console.log(data + " success in updating item");
},
error: function(data) {
alert(JSON.stringify(item));
console.log(data);
}
});
});
}
}
