Hi everyone,

I'm using the following example (https://developers.arcgis.com/javascript/latest/sample-code/identity-oauth-basic/) to get the access to the items in our ArcGIS Enterrpise portal.

I have adapted the example so that all items (Web Mapping Application, Dashboards, ...) are displayed by a group in which I have only changed the "query" property, i.e. added the group id. (query: "group: 59bd561ffc0c50e5b390ef9e78352de6")

The access to the ArcGIS Enterprise portal works great and the thumbnails of the web mapping application are displayed in the gallery.

The question:
How can the web mapping applications and dashboards be opened in the new browser window when the user clicks on the thumbnail?

I am very grateful for any help!

Code:

You can add the target="_blank" attribute to the HTML element to open a link in a new tab or window.

Hi ben,

Thank you very much for your hint!
But that can't help me. The "href" only refers to a single URL. I currently have three apps in the group with the above group id in the ArcGIS Enterprise portal and thus in the gallery.

I searched online for a solution and found a little code (hint) from Rene Rubalcava (Solved: Re: How to access function in require([]) - Esri Community) that got me further.

I have expanded and adapted the "createGallery ()" function a little. When the user clicks on thumbnail, the corresponding url is written in the method window.open (); called up and the app is opened in a new tab.

In case anyone has better simpler solution feel free to post. Here is my code:

 

 

function createGallery(items) {
    let htmlFragment = "";

    items.results.forEach((item) => {
        htmlFragment +=
            '<div class="esri-item-container">' +
            (item.thumbnailUrl ?
                '<div class="esri-image" style="background-image:url(' + item.thumbnailUrl + ');"></div>' :
                '<div class="esri-image esri-null-image">Thumbnail not available</div>') +
            (item.title ?
                '<div class="esri-title">' + (item.title || "") + "</div>" :
                '<div class="esri-title esri-null-title">Title not available</div>') +
            // (item.description) + 
            "</div>";
    });
    document.getElementById("itemGallery").innerHTML = htmlFragment;

    // add the event listeners
    var elements = Array.from(document.querySelectorAll(".esri-item-container"));
    elements.forEach(element => {
        element.addEventListener("click", clickHandler);
    });

    // title of all apps and dashboards in the galery
    var app_1 = elements[0].innerText;
    var app_2 = elements[1].innerText;
    var app_3 = elements[2].innerText;

    function clickHandler(event) {
        // do something with clicked element

        var app_path_title = event.path[1].innerText;
        //console.log(app_path_title);

        var apps_url = items.results;
        //console.log(test_results);

        // apps url 
        var app_1_url = items.results[0].url;
        var app_2_url = items.results[1].url;
        var app_3_url = items.results[2].url;

        if (app_1 === app_path_title) {
            window.open(app_1_url);
        } else if (app_2 === app_path_title) {
            window.open(app_2_url);
        } else if (app_3 === app_path_title) {
            window.open(app_3_url);
        };
    };
};
