To get the dimensions of an SVG file inside an iframe, you can use JavaScript to access the content of the iframe and then retrieve the dimensions of the SVG element.


Here's a step-by-step guide on how to do this:

  1. First, make sure that the iframe has a unique ID that you can refer to in your JavaScript code. For example, you can add an ID attribute to the iframe element like this:
1
<iframe id="svgFrame" src="your-svg-file.svg"></iframe>


  1. Next, you can use JavaScript to access the content of the iframe and get the dimensions of the SVG element inside it. Here's an example of how you can do this:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
// Get the iframe element by its ID
var iframe = document.getElementById('svgFrame');

// Get the document object of the iframe
var iframeDoc = iframe.contentDocument || iframe.contentWindow.document;

// Get the SVG element inside the iframe
var svgElement = iframeDoc.querySelector('svg');

// Get the dimensions of the SVG element
var svgWidth = svgElement.getAttribute('width');
var svgHeight = svgElement.getAttribute('height');

// Display the dimensions of the SVG element
console.log('SVG width: ' + svgWidth);
console.log('SVG height: ' + svgHeight);


  1. You can further use the dimensions retrieved to manipulate the SVG file as needed in your application.


By following these steps, you can easily get the dimensions of an SVG file inside an iframe using JavaScript.
