Passing JSON object to HTML Web resource

Posted on by Jayakumar 390

Hi,

How to pass json object to web resource. We are calling web api on form load and displaying the data in the form. Some values we get from api need to be displayed in the html web resource. How to pass JSON data to web resource. I know I can call the same api in the web resource. But we don't want that because I have more than 5 web resources where we want to show the data. I cannot call the api on each web resource. I just want to call on load and load the data in crm form and web resources.

Thnaks

    Sorry i have been busy.

    Another way is using localStorage. Supported by all browsers and is safe, of course only if you dont have a lot of sensitive data. Permits storing large size of data. You can read about it here http://www.w3schools.com/html/html5_webstorage.asp.

    So in your case you can do it.

    var myVariableInDynamicsForm = {key : value};
localStorage.setItem("myVariable", JSON.stringify(myVariableInDynamicsForm));



var myVariableInWebresource = JSON.parse(localStorage.getItem("myVariable"));

    Hi,

    Anyone please answer how to access parent variable from iframe web resource in crm 2016 using turbo form. When I switched back to Legacy mode I can access the parent variable using code below.

    legacy.png

    window.parent.myVariable

    So the problem is due to turbo form. So is there no way to access the parent variable from iframe using turbo form?

    Hi MehrCrm,

    window.parent.myVariable gives undefined error. It works in MS CRM 2011 but not in 2016. Is it because due to introduction of turbo forms in CRM 2016??

    Thanks,

    This does not work in MS CRM 2016. But it works in crm 2011. I can acces the variable in parent script in iframe in crm 2011. But when I use the same code in crm 2016 I am getting undefined error.

    Sorry my mistake. Access it:

    var myVariableInWebResource = window.parent.myVariable;

    Remove document.

    Please add (or use existing) form onload handler in your JS web resource where the global variable is defined.

    var myVariable = {"key" : "value"};

    function FormOnloadHandler(context) {

    // This resource is being loaded as an iframe

    // Add a new variable with the same name to the parent of this iframe, main form window

    // Assign your local variable to the main form window which then becomes accessible from any web resource on the form

        window.parent.myVariable = myVariable;

    }

    In your web resource, access the variable:

    if (window.parent.myVariable) {

        // window.parent.myVariable

    }

    Hope this helps

    Hi Agust,

    No. I cannot access the variable which is in the CRM main from form the IFrame Web resource. We can access the parent form fields but not the variable. The variable is declared as global.

    Thanks.
