I want to send key value pairs to my php page, but I need to set the key and value dynamically from data tags.
Here's the code I have until now:
function send(){
var attr = new Array();
var key = $('#add').attr('data-key');
var value = $('#add').attr('data-value');
attr.push({ key : value });
var data = {attributes: attr};
$.ajax({
url: "ajax.php",
type: "POST",
data: data,
success: function(result) {
alert(result)
}
});
}
This is not the actual code, it's just the basic functionality.
The problem is here:
attr.push({ key : value });
The 'key' is not taken as the variable I've set.
Can I please get some help? I'd really appreciate it. Thank you very much!
Since ECMAScript 6 (2015) it's possible to use computed object property names, which is supported by all current browsers and other JavaScript environments:
attr.push({ [key] : value });
Use the bracket notation:
Instead of attr.push({ key : value }); use
var object = {};
object[key] = value;
attr.push(object);
