使用jspdf将HTML表导出为pdf
使用jspdf将HTML表导出为pdf
提问于 2014-04-13 04:38:39
我需要使用jspdf将HTML表导出到pdf文件。我尝试了下面的代码，但它在pdf文件中显示空白/空输出。这方面的任何建议或示例代码都会很有帮助。`
<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, 15, {
'width': 170,'elementHandlers': specialElementHandlers
});
doc.save('sample-file.pdf');
});
});
}
</script>

以下是工作示例：
在头部
<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>

<td>1,241,900,000</td>

<td>201,032,714</td>
<td>July 1, 2013</td>
<td>2.81</td>
</tr>
</tbody>
</table>
</div>和按钮来运行：
<button onclick="javascript:demoFromHTML()">PDF</button>和在线工作示例：

您也可以使用jsPDF-AutoTable插件。您可以查看使用以下代码的演示here。
var doc = new jsPDF('p', 'pt');
var elem = document.getElementById("basic-table");
var res = doc.autoTableHtmlToJson(elem);
doc.autoTable(res.columns, res.data);
doc.save("table.pdf");Stack Overflow用户

使用get(0)而不是html()。换句话说，替换
doc.fromHTML($('#htmlTableId').html(), 15, 15, {
'width': 170,'elementHandlers': specialElementHandlers
});使用
doc.fromHTML($('#htmlTableId').get(0), 15, 15, {
'width': 170,'elementHandlers': specialElementHandlers
