如何从 .svg 文件中获取 svg 图标作为字符串

Question

Is there a way to get svg icon as a string while you have the .svg file with JavaScript ?

To be more clear, I need a function which does:

function svgFileToString('./icon.svg'){
...
...
return `<svg>...</svg>`
}

You can use the fetch() function. The function svgFileToString() will not return anything, but you can replace console.log(text); with whatever.

For the example I'm using a data URL to replace the real path to a file.

 function svgFileToString(iconpath){ fetch(iconpath) .then(response => response.text()) .then(text => { console.log(text); // do whatever }); } //svgFileToString('/icon.svg'); // for testing here on ST: svgFileToString('data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI1MCIgaGVpZ2h0PSI1MCI+CiAgPHJlY3Qgd2lkdGg9IjEwMCUiIGhlaWdodD0iMTAwJSIgZmlsbD0iZ3JlZW4iIC8+Cjwvc3ZnPgo=');
