var targetDom = $(target);

var copyDom = targetDom.clone();

copyDom.width(targetDom.width() + "px");

copyDom.height(targetDom.height() + "px");

svg2canvas(copyDom);

html2canvas(copyDom, {

onrendered: function (canvas) {

} else {

var doc = new jsPDF('p', 'mm', [this.width * 0.225, this.height * 0.225]);

}

};

copyDom.remove();

background: "#fff",

allowTaint: true

});

}

function svg2canvas(targetElem) {

var svgElem = targetElem.find('svg');

svgElem.each(function (index, node) {

var parentNode = node.parentNode;

var tempNode = document.createElement('div');

tempNode.appendChild(node);

var svg = tempNode.innerHTML;
