How to addEventListener to a button in popup content of ArcGIS API for JS

NoorMaria — Sun, 24 Apr 2022 08:03:17 GMT

I have created a custom popup with the popupTemplate function with ArcGIS JS API 4.x

And i add a button in popup content by html.

but i can not addEventListener to a button in popup.

here is the way i am try to do now: ((the full code is here:https://codepen.io/llllllllc/pen/mdpabGw material))

return html to create button in popup content

const popupTemplate = {
                // autocasts as new PopupTemplate()
                title: "Population in {NAME}",
                content: populationChange,
                };

                layer.popupTemplate = popupTemplate;

                function populationChange(feature) 
                {
                    const div = document.createElement("div");
                    div.innerHTML =
                        "<input type='button' id='btn' value='CLICK'>";
                    return div;
                }

watch content change

view.popup.watch("content", (newValue, oldValue, propertyName, target) => {......});

3.querySelector("#btn") then addEventListener but it fail ,and console.log(btn) show btn is null

const btn = document.querySelector("#btn");
console.log(btn)
btn.addEventListener(
    "click",
    function () {
        lert("HELLO WORLD!");
    },
   false
);a

Here is a sample adding a button to the popup content.

You can either reuse the button you create, or be sure to remove the event listener if you don't

This is using the CustomContent of the PopupTemplate

Along similar lines.

function populationChange(feature) { const div = document.createElement("div"); const btn = document.createElement("button") btn.innerHTML = 'Click Me' btn.onclick = function(props) { alert('hello world.') } return div.appendChild(btn) }
