问题描述
我想用纯JavaScript编写代码吗？这适用于JQUERY1-2。注意：不寻找MVC Core 1+
I'm looking to code this in pure JavaScript please? This works for JQUERY1-2. Note: Not looking for MVC Core 1+
var sMVCParameter1 = "1";
var sMVCParameter2 = "2";
var sToken = document.getElementsByName("__RequestVerificationToken")[0].value;
$.ajax({
url: "/Home/ClickCreateAccount/",
type: "POST",
contentType: "application/x-www-form-urlencoded",
data: { '__RequestVerificationToken': sToken, 'sMVCParameter1': sMVCParameter1, 'sMVCParameter2': sMVCParameter2 }
})
.done(function (data) {
//Process MVC Data here
})
.fail(function (jqXHR, textStatus, errorThrown) {
//Process Failure here
});
我尝试了什么：

JavaScript可能会是这样的

What I have tried:
==========================================================
The JavaScript Might Look like this
==========================================================
<script type="text/javascript">
function Test_JS_Ajax() {
var sToken = document.getElementsByName("__RequestVerificationToken")[0].value;
var xmlHttp;
//Let us create the XML http object
xmlHttp = null;
if (window.XMLHttpRequest) {
//for new browsers
xmlHttp = new XMLHttpRequest();
}
else if (window.ActiveXObject) {
var strName = "Msxml2.XMLHTTP"
if (navigator.appVersion.indexOf("MSIE 5.5") >= 0) {
strName = "Microsoft.XMLHTTP"
}
try {
xmlHttp = new ActiveXObject(strName);
}
catch (e) {
alert("Error. Scripting for ActiveX might be disabled")
return false;
}
}
if (xmlHttp != null) {
//Handle the response of this async request we just made(subscribe to callback)
xmlHttp.onreadystatechange = function () {
if (xmlHttp.readyState == 4 && xmlHttp.status == 200) {
var data = JSON.parse(xmlHttp.responseText);
alert(data);
}
}
xmlHttp.onerror = function () {
//Not Connected
}
//Pass the value to a web page on server as query string using XMLHttpObject.
//VERSION 1 TESTED FAILED
//xmlHttp.open("GET", "/Home/Test/?sString1=" + "1", true);

xmlHttp.send(JSON.stringify({ "sString1": "1" }));
}
else {

推荐答案
.ajax（{
url：/ Home / ClickCreateAccount /，
type： POST，
contentType：application / x-www-form-urlencoded，
data：{'__ RequestVerificationToken'：sToken，'sMVCParameter1'：sMVCParameter1，'sMVCParameter2'：sMVCParameter2}
}）
.done（函数（数据）{
//处理MVC数据这里
}）
.fail（函数（jqXHR，textStatus，errorThrown）{
//处理失败这里
}）;
.ajax({ url: "/Home/ClickCreateAccount/", type: "POST", contentType: "application/x-www-form-urlencoded", data: { '__RequestVerificationToken': sToken, 'sMVCParameter1': sMVCParameter1, 'sMVCParameter2': sMVCParameter2 } }) .done(function (data) { //Process MVC Data here }) .fail(function (jqXHR, textStatus, errorThrown) { //Process Failure here });

使用Fetch - Web API | MDN [ ^ ]
如果您需要支持Internet Explorer，则需要两个polyfill：
GitHub - github / fetch：一个window.fetch JavaScript polyfill。 [ ^ ]
GitHub - WebReflection / url-search -params：用于URLSearchParams标准的简单polyfill [ ^ ]

我找到了一种适用于所有浏览器并在下面测试的方法。如果您有以下任何代码更新，请告诉我们。谢谢。
I found a way that works in all browsers and tested below. If you have any code updates to below let me know thank you.
var xmlHttp = null;
if (window.XMLHttpRequest) {
xmlHttp = new XMLHttpRequest();
}
else if (window.ActiveXObject) {
var versions = [
"MSXML2.XmlHttp.6.0",
"MSXML2.XmlHttp.5.0",
"MSXML2.XmlHttp.4.0",
"MSXML2.XmlHttp.3.0",
"MSXML2.XmlHttp.2.0",
"Microsoft.XmlHttp"];
var xhr;
for (var i = 0; i < versions.length; i++) {
try {
xmlHttp = new ActiveXObject(versions[i]);
break;
} catch (e) {
}
}
}
if (xmlHttp != null) {
xmlHttp.onreadystatechange = function () {
if (xmlHttp.readyState == 4 && xmlHttp.status == 200) {
document.getElementById("divLOAD").style.display = "none";
var data = JSON.parse(xmlHttp.responseText);
if (data == "" && sIsAutoComplete == "F") {
PlateResult("", "", "", "", "RED", sSearch);
return;
}
else if (data == "") {
return;
}
if (sIsAutoComplete == "T") {
return AutoComplete(data);
}
else if (sIsAutoComplete == "F") {
SearchPlateShow(data, "F");
}
else if (sIsAutoComplete == "A") {
s_CacheSelectedCompanyID = s_SelectedCompanyID;
AllData = data;
var dt = new Date();
CacheDate.setTime(dt.getTime() + (CacheMinutes * 60 * 1000)); //1 minute //days (exdays * 24 * 60 * 60 * 1000) || minute (exdays * 60 * 1000)
}
}
}
xmlHttp.onerror = function () {
document.getElementById("divLOAD").style.display = "none";
if (sIsAutoComplete == "T") {
return AutoComplete(AllData);
}
else if (sIsAutoComplete == "F") {
SearchPlateShow(AllData, "T");
}
}
xmlHttp.open("POST", "/Home/SearchPlate/", true);
xmlHttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xmlHttp.send('__RequestVerificationToken=' + sToken + '&sLicensePlate=' + Encode(sLicensePlate) + '&sIsAutoComplete=' + sIsAutoComplete + '&sID=' + s_SelectedCompanyID + '&sKey=' + sKey + '&sIV=' + sIV);
}
else {
//Browser not supported! Please update your browser!
document.getElementById("spParkingTracker").innerHTML = "Browser not supported!";
}
