Toggle switch to call url but not open it

I have a toggle switch on my html which i would like to enable/disable a relay in arduino with.
On: call http://192.168.1.144:8000/1234!Q02=0$
Off: call http://192.168.1.144:8000/1234!Q02=1$
I don't want the url to be opened, i just want it to be called.
function getValue1() {
var isChecked = document.getElementById("button1").checked;
if(isChecked){
alert("button1 is checked");
} else {
alert("button1 is NOT checked");
}
}
My javascript code is working, but i dont know how to call the url.
Thanks.

you can also try this.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$("#btnCall").click(function(){
if($("button1").prop('checked')){
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "http://192.168.1.144:8000/1234!Q02=0$",
data: JSON.stringify(data), //yourData
success: function (data) {
console.log(data);
},
dataType: "json"
});
} else {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "http://192.168.1.144:8000/1234!Q02=1$",
data: JSON.stringify(data), //yourData
success: function (data) {
console.log(data);
},
dataType: "json"
});
}
});
});
</script>

Button:
$(document).ready(function() {
$("#btnCall").click(function(){
var isChecked = document.getElementById("button1").checked;
if(isChecked){
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "http://192.168.1.144:8000/1234!Q02=0$",
data: JSON.stringify(data), //yourData
success: function (data) {
console.log(data);
},
dataType: "json"
});
} else {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: "http://192.168.1.144:8000/1234!Q02=1$",
data: JSON.stringify(data), //yourData
success: function (data) {
console.log(data);
},
dataType: "json"
});
}
});
});

How to access the data from an ajax call outside the function itself

This code gets a json object from another server.
How do I access the response outside of the function?
(function($) {
$.ajax({
type: 'GET',
url: url,
async: false,
jsonpCallback: 'callback',
contentType: "application/json",
dataType: 'jsonp',
success: function(json) {
var data = json;
}
})
})(jQuery);

You can do something like this!
_outerMethod: function(data) {
//...do what you need to do
}, (function($) {
$.ajax({
type: 'GET',
url: url,
async: false,
jsonpCallback: 'callback',
contentType: "application/json",
dataType: 'jsonp',
success: function(json) {
_outerMethod(json);
}
})
})(jQuery);

Converting $.post into $.ajax

I have a post statement,
$.post("panel.php", 'data=[{"action":"UserInfo"}]', function (userInfo){
//processing
});
I need it to be converted to $.ajax so made it thus,
$.ajax({
type: "POST",
url: "panel.php",
data: { data: [{"action":"UserInfo"}]},
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(userInfo) {
//processing
}
});
But the post variable isn't being sent. Is this not the correct way?

Can you try something like this:
$.ajax({
type: "POST",
url: "panel.php",
data: {"action":"UserInfo"},
success: function(userInfo) {
//processing
}
});

Try this
$.ajax({
type: "POST",
url: "panel.php",
data: "action="+"UserInfo",
success: function(userInfo) {
//processing
}
});

Remove data from your data and keep it in a variable, stringify before your send as below
var data={"action":"UserInfo"};
$.ajax({
type: "POST",
url: "panel.php",
data: JSON.stringify(data),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(userInfo) {
//processing
}
});

Your data attribute was not written as correct JSON:
data: { "data": [{"action":"UserInfo"}]},
You need quotation marks around the items inside your JSON object. You can use JSONLint to check if your JSON object is valid.

$.ajax({
type: "POST",
url: "panel.php",
data: {"action":"UserInfo"},
dataType: "json",
success: function(userInfo) {
//processing
}
});
Need a small change. there is a predefined format to send data in ajax,
data: {status: status, name: name},
data: "status="+status+"&name="+name.
Follow any one of the approach.

try like this,
$.ajax({
type: "POST",
url: "panel.php",
data: {"action":"UserInfo"},
success: function(userInfo) {
}
});

Ajax post doesn't pass any data to MVC controller

This:
$.ajax({
url: '/Merchant/SaveDirty',
type: 'POST',
dataType: 'json',
data: ko.toJSON(dirtyItems),
contentType: 'application/json; charset=utf-8',
success: function (data) {
// get the result and do some magic with it
//var message = data.Message;
alert(ko.toJSON(dirtyItems));
}
});
...currently calls this:
[HttpPost]
public void SaveDirty(string json)
{
}
...but when I hit the breakpoint in SaveDirty, no data is passed. I've verified that ko.toJSON(dirtyItems) returns a JSON string in the javascript. What am I doing wrong?
Thanks!

#KillingsWorth, is there any specific reason for which you are posting a JSON string? If not then, you could create a class corresponding to dirtyitems type and in your controller method you can accept a list of dirtyItems.
Class DirtyItem
{ // dirty item properties }
[HttpPost]
public void SaveDirty(List<DirtyItem> dirtyItems)
{
}

you can use the following:
$.ajax({
url: '/Merchant/SaveDirty',
type: 'POST',
dataType: 'json',
data: JSON.stringify(dirtyItems),
contentType: 'application/json; charset=utf-8',
success: function (data) {
///
///
}
});
But if you are using knockout.js in your applicantion then you should do the following:
$.ajax({
url: '/Merchant/SaveDirty',
type: 'POST',
dataType: 'json',
data:JSON.stringify(ko.mapping.toJS(dirtyItems)),
contentType: 'application/json; charset=utf-8',
success: function (data) {
// get the result and do some magic with it
//var message = data.Message;
alert(ko.toJSON(dirtyItems));
}
});

This should works:
$.ajax({
url: '#Url.Action("SaveDirty", "Merchant")'
type: 'POST',
dataType: 'json',
data: JSON.stringify(dirtyItems),
contentType: 'application/json; charset=utf-8',
success: function (data) {
// get the result and do some magic with it
//var message = data.Message;
alert(ko.toJSON(dirtyItems));
}
});

AJAX POST JSON value

I have AJAX POST, the result is JSON:
$.ajax({
type: "POST",
url: "../../api/test",
data: JSON.stringify(source),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
var upload = JSON.stringify(result);
console.log(upload);
}
});
The upload result is:
{"Link":0,"Title":"d","Description":"dada","Keywords":"dad"}
How can I get the value of Title?

Do not stringify the result, just use result.Title.

As you already have JSON string, It's simple as a pie!
All you need to do is to call the property you want from the variable you assigned your result to.
for example:
var post_response;
$.ajax({
type: "POST",
url: "../../api/test",
data: JSON.stringify(source),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (result) {
post_response = JSON.stringify(result);
console.log("Title: "+post_response.Title);
}
});
hope this helps.
