I would like to execute a script from a JavaScript file but due the same origin policy measure, I can't.

I tried to execute put the script in a string and pass it to the function.

js.exec()

However I cannot execute this script due the fact that the string is too long.

This is how I pass the script.

class TheClass extend GebReportingSpec {
....
and:'I execute the script'
      js.exec('''
        $.getScript("http://localhost/jscript/html2canvas.js", function() { 
        var height = Math.round($("#TopImageContainer").height());
        var width =  Math.round($("#TopImageContainer").height());
        // function() { 
        html2canvas($("#TopImageContainer"), {
            onrendered: function (canvas) {
                 var tempcanvas = document.createElement("canvas");
                 tempcanvas.width = width;
                 tempcanvas.height = height;
                 var context = tempcanvas.getContext("2d");
                context.drawImage(canvas,0,0,width,height,0,0,width,height);
                 var link = document.createElement("a");
                 link.href = tempcanvas.toDataURL("image/png"); 
                 link.download = "myElement.png";
               link.click();
          }
    }); 

     });''')
    }

I am getting the following error:

The given string is 126694 Unicode code units long, but only a maximum of 65535 is allowed.

What can I do?

Maybe you should just copy the functions you need. – akaAlso Jan 17 '18 at 15:57
I tried it but the string is still too long – user4237435 Jan 17 '18 at 15:59

How is this related to `groovy`/`spock`/`geb`? – Leonard Brünings Jan 17 '18 at 22:46
can you reduce your problem to a [mcve]? – blurfus Jan 18 '18 at 07:01
Are you trying to create a screenshot or what is it that you actually want to do here? – Leonard Brünings Jan 18 '18 at 18:22
@LeonardBrünings I am trying to creat a screenshot of an element, not the whole page. – user4237435 Jan 19 '18 at 08:59

I'd suggest to just use Webdriver instead https://stackoverflow.com/a/13834607/2145769 – Leonard Brünings Jan 19 '18 at 10:36
Strange. That string you are using is not nearly 65535 chars long. Can you provide a full stack trace? – Michael Dec 17 '19 at 13:17
