Rules:

Recommended documentation link: https://docs.looker.com/reference/embedding/embed-javascript-events#making_changes_to_the_iframe

1 - Make sure this is a private look, and not a public one(as the public looks does not contain filters for security reasons).

2 - Different from the dashboard filters update, the look filters update, require two javascript event request.

a. First send the request to change the filter:

         {
          "type": "look:filters:update", 
           "filters": {
               "view_name.field_name": "filer_value_desired",
           }

b. First send the request run the look:

         var my_request = JSON.stringify(
           {
             type: "dashboard:run"
           }

On my example (index.html), I created a button in the page I am embedding the look in, with the function doRequest() when we click on it:

<button onclick="doRequest()">CHANGE</button>  

Then, I apply the filter event inside of the doRequest() function as part of the script tag (<script></script>):

        ```
          function doRequest() {

                document.getElementById('looker').contentWindow.postMessage(
                 JSON.stringify(
                     }
                         "type": "look:filters:update", 
                         "filters": {
                             "products.brand": "ECHO",
                         }
                 ),
                 'https://localhost:9999' 
                );

                document.getElementById('looker').contentWindow.postMessage(
                 JSON.stringify(
                     {
                         "type": "look:run" // then we run the request
                     }
                 ),
                 'https://localhost:9999'
                );

              }
        ```

Host the html file on your local host:

1 - Make sure you have python installed on your machine (I used the Python version 2.7).

2 - Open the terminal and navigate to the folder your .html file is saved on your machine.

3 - Run the following command:

	python -m SimpleHTTPServer 8081

4 - go to your browser and open this page: http://localhost:8081/ and click in the name of your html file.
In the end you should have your file hosted in a url that looks something like this:

http://localhost:8081/iframe%20test.html

great content, do you think it is possible to implement a similar solution but with a PUBLIC EMBEDDED LOOK ?
