我需要使用jspdf导出HTML表格到pdf文件。我尝试了以下代码，但它显示在pdf文件中的空白/空输出。任何建议或示例代码将是有帮助的。
`
`
<script type="text/javascript">
function demo1() {
$(function () {
var specialElementHandlers = {
'#editor': function (element,renderer) {
return true;
}
};
$('#cmd').click(function () {
var doc = new jsPDF();
doc.fromHTML($('#htmlTableId').html(),15,{
'width': 170,'elementHandlers': specialElementHandlers
});
doc.save('sample-file.pdf');
});
});
}
</script>

解决方法
这里是工作示例：
在头上
<script type="text/javascript" src="jspdf.debug.js"></script>
脚本：
<script type="text/javascript">
function demoFromHTML() {
var pdf = new jsPDF('p','pt','letter');
// source can be HTML-formatted string,or a reference
// to an actual DOM element from which the text will be scraped.
source = $('#customers')[0];
// we support special element handlers. Register them with jQuery-style
// ID selector for either ID or node name. ("#iAmID","div","span" etc.)
// There is no support for any other type of selectors
// (class,of compound) at this time.
specialElementHandlers = {
// element with id of "bypass" - jQuery style selector
'#bypassme': function(element,renderer) {
// true = "handled elsewhere,bypass text extraction"
return true
}
};
margins = {
top: 80,bottom: 60,left: 40,width: 522
};
// all coords and widths are in jsPDF instance's declared units
// 'inches' in this case
pdf.fromHTML(
source,// HTML string or DOM elem ref.
margins.left,// x coord
margins.top,{// y coord
'width': margins.width,// max width of content on PDF
'elementHandlers': specialElementHandlers
},function(dispose) {
// dispose: object with X,Y of the last line add to the PDF
// this allow the insertion of new lines after html
pdf.save('Test.pdf');
},margins);
}
</script>
和表：
<div id="customers">
<table id="tab_customers" class="table table-striped" >
<colgroup>
<col width="20%">
<col width="20%">
<col width="20%">
<col width="20%">
</colgroup>
<thead>
<tr class='warning'>
<th>Country</th>
<th>Population</th>
<th>Date</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td>Chinna</td>
<td>1,363,480,000</td>
<td>March 24,2014</td>
<td>19.1</td>
</tr>
<tr>
<td>India</td>
<td>1,241,900,2014</td>
<td>17.4</td>
</tr>
<tr>
<td>United States</td>
<td>317,746,2014</td>
<td>4.44</td>
</tr>
<tr>
<td>Indonesia</td>
<td>249,866,000</td>
<td>July 1,2013</td>
<td>3.49</td>
</tr>
<tr>
<td>Brazil</td>
<td>201,032,714</td>
<td>July 1,2013</td>
<td>2.81</td>
</tr>
</tbody>
</table>
</div>
并按钮运行：
<button onclick="javascript:demoFromHTML()">PDF</button>
