send data js code example
Example 1: javascript send post request
let data = {element: "barium"};
fetch("/post/data/here", {
method: "POST",
body: JSON.stringify(data)
}).then(res => {
console.log("Request complete! response:", res);
});
// If you are as lazy as me (or just prefer a shortcut/helper):
window.post = function(url, data) {
return fetch(url, {method: "POST", body: JSON.stringify(data)});
}
// ...
post("post/data/here", {element: "osmium"});
Example 2: javascript ajax post form data
$(document).ready(function() {
// process the form
$('form').submit(function(event) {
// get the form data
// there are many ways to get this data using jQuery (you can use the class or id also)
var formData = {
'name' : $('input[name=name]').val(),
'email' : $('input[name=email]').val(),
'superheroAlias' : $('input[name=superheroAlias]').val()
};
// process the form
$.ajax({
type : 'POST', // define the type of HTTP verb we want to use (POST for our form)
url : 'process.php', // the url where we want to POST
data : formData, // our data object
dataType : 'json', // what type of data do we expect back from the server
encode : true
})
// using the done promise callback
.done(function(data) {
// log data to the console so we can see
console.log(data);
// here we will handle errors and validation messages
});
// stop the form from submitting the normal way and refreshing the page
event.preventDefault();
});
});
