I have get the variable from onEachFeature function and set on a HTML tag, like this

function onEachFeature(feature, layer) {
  layer.bindPopup(feature.properties.TenCty); 
  layer.on("click", function(e)
  {
    var popup = e.target.getPopup();
    var content = popup.getContent();
    document.getElementById('test').textContent = content;
   } 
};

This is my PHP

<body>
        <h2>My Map</h2>
        <p id="test"></p>
        <div id="map"></div>
        <script src="js/new.js"> </script>
</body>

I have get the value to show on HTML but I want the variable to get to PHP? Exactly is the content from popup (content variable) to echo to PHP?

So you have an HTML textbox and you want to place the clicked features attribute into the textbox. Here I get the textbox, then set the value.

onEachFeature: function (feature, layer) {          
   layer.on('click', function (e) {     

     var a = document.getElementById("test");
    a.innerHTML=e.target.feature.properties.TenCty);

  • No, I mean, I want the value from this "e.target.feature.properties.TenCty", to pass to PHP variable. Anyway, thanks very much. Actually, I have read about ajax to send variable to PHP, but I don't know why it didn't work – Diao Vũ Jul 21 '18 at 3:20

So you know how to get the value from a click, then pass it to a function that uses AJAX to send it to your PHP page.

In JavaScript

passToPHP("e.target.feature.properties.TenCty);


function passToPHP(myVariable){

    var dataString = 'var1=' + myVariable 

    $.ajax({
            type: "POST",
            url: "UpData.php",  //my PHP page
            data: dataString,
            cache: false,
        success: function() {
            console.log("Data sent by POST");
        }
    });
}

In PHP

if (isset($_POST['var1'])) {
    $thePassedVariable = $_POST['var1'];
}
