AEM : Access to global values from dialog-clientlib

Forum|Forum|5 years ago

Currently, I am storing certain value as in data-attributes in customheaderlibs.html

<div data-sly-use.myjava="MyJava"
     data-score="${myjava.getScore}"
     data-team="${myjava.getTeam}"></div>

and were reading these values by

const iframeContents = document.querySelector('iframe').contentWindow.document.body;
        const configElement = iframeContents.querySelector('div[data-score]');

This works fine for certain resolution of a screen. But in smaller viewport such as in iPad where cq dialog opens as a full screen and not as a dialog box, customheaderlibs.html seems to be absent from the DOM. Hence, these data cannot be accessed from javascript on dialog-ready. Is there any way these data can be accessed, may be if passed as query parameter to the granite dialog path? But not sure how to achieve this.

@infinityskyline, maybe you can create a servlet that would be called by your cq.authoring.editor.hook client library. Right, and reviewing your custom JavaScript code, when writing custom logic for cq.authoring.editor.hook, and you should tick to ES5 syntax, as ES6 syntax is not yet supported by browsers like IE11.

<?xml version="1.0" encoding="UTF-8"?>
<jcr:root xmlns:cq="http://www.day.com/jcr/cq/1.0" xmlns:jcr="http://www.jcp.org/jcr/1.0"
    jcr:primaryType="cq:ClientLibraryFolder"
    allowProxy="{Boolean}true"
    categories="[cq.authoring.editor.hook]"
    dependencies="[cq.authoring.editor.core]"/>

// the client library js file

$.get( "/bin/mycustomservlet", function( response ) {
    // do something with the response
});

Hi,
I would suggest to read this value in dialog using ajax call on dialog-load.

you can simply make a call to same page with div id/class to get the custom data-attribute DOM.

check Loading Page Fragments part on https://www.tutorialrepublic.com/jquery-tutorial/jquery-ajax-load.php

@briankasinglihttp://localhost:4502/bin/mycustomservlet?_=1610179346273 is not accessible throwing 404. Checked config manager /bin/ is there in the execution path. But the servlet is not present in the project bundle.

Hi @infinityskyline,

If I understand your query correctly, you are trying to access the HTML elements in JS. Please refer to my answer here.

Hope this helps.

Thanks,

One way I can think of is, If the values of score, team are stored in node, then get the form action attribute and hit with .json extension and read the values of score and team.

$.ajax({
    url: $("form.cq-dialog").attr("action") + ".json",
    async: false,
    success: function (data) {
        console.log(data.score);
    }
});

One more way is, if you use Sling Model (I see you are using Use API here in example) and even if values of score, team are not stored as part of node you can hit the same action attr path with model selector and JSON extension you can get values.

$.ajax({
    url: $("form.cq-dialog").attr("action") + ".model.json",
    async: false,
    success: function (data) {
        console.log(data.score);
    }
});
