如何提取javascript生成的DOM对象的html代码？

Question

I am generating a svg object in a html document using java script. Something like this:

mySvg = document.createElementNS("http://www.w3.org/2000/svg", "svg");
myPath = document.createElementNS("http://www.w3.org/2000/svg", "path");
mySvg.appendChild(myPath);

Is there a javascript command to extract what the resulting html code would be?

ie

"<svg>...<path>...</path>...</svg>"

I want to then save this part as a string variable.

Thanks, Wendy

Answer 1

Yeah...Put your svg tag into a div and then get the Html of that div.

<div id="container"></div>
$('#container').append('mySvg');

And for the whole svg as an html, you can do this:

var svgHtml = $('#container').html();

For the string:

var svgHtml = document.getElementById('container').innerText;

Answer 2

You can use the innerHTML to get the html text for an element

mySvg = document.createElementNS("http://www.w3.org/2000/svg", "svg");
myPath = document.createElementNS("http://www.w3.org/2000/svg", "path");
mySvg.appendChild(myPath);

document.getElementById('x').appendChild(mySvg);

console.log(document.getElementById('x').innerHTML)
