当用户点击GeneratePDF按钮时,我需要将html页面导出为PDF文件.我成功将HTML页面导出为PDF文件,但只有第一次点击我才能将数据下载到PDF中,但是从第二次点击我无法将数据下载到PDF文件.我不确定我在代码中出错了.
请在这里查看代码:
$(function() {
var doc = new jsPDF();
var specialElementHandlers = {
'#editor': function(element, renderer) {
return true;
}
};
$('#cmd').click(function() {
doc.fromHTML($('#target').html(), 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
doc.save('sample-file.pdf');
});
