为什么.html()不适用于使用jquery的SVG选择器? [英] Why .html() doesn't work with SVG selectors using jquery ?
问题描述
问题可以告诉我如何将我的SVG元素转换为字符串?
我正在使用
innerHTML code>这是为html,而不是svg。 SVG是xml文档,因此您可以使用 XMLSerializer()
var svg = document.getElementById('svg_root'); //或任何你称之为的
var serializer = new XMLSerializer();
var str = serializer.serializeToString(svg);
Question can some one tell me how can i convert my SVG element to a string ?
i'm using canvg to convert my SVG to an image.
it has to be render in a canvas first , the canvg()
method is expecting a SVG STRING
code :
function updateChartImage(){
canvg(document.getElementById('canvas'),expecting ` svg string`);
var canvas = document.getElementById("canvas") ;
var img = canvas.toDataURL("image/png");
img = img.replace('data:image/png;base64,', '');
$("#hfChartImg").val(img) ;
$('#img').attr({ src: img });
}
i have tried
$('#container svg').html() ; // it gives me an error
//Uncaught TypeError: Cannot call method 'replace' of undefined
notice that
$('#container svg')
$('#container').html() // both works fine and
UpDATE
i'm using highcharts the have a getSVG() function that i can pass to the canvg() but the problem is it dosen't get the latest updates , so i have to do it this way , when running the getSVG()
function i get the following :
解决方案 As far as I can recall jQuery's .html()
makes use of innerHTML
which is meant for html, not svg. SVG's are xml documents, so you can use XMLSerializer()
var svg = document.getElementById('svg_root'); // or whatever you call it
var serializer = new XMLSerializer();
var str = serializer.serializeToString(svg);
