**Question & Answer :**
I person the pursuing html codification:
```
<html> <assemblage> <p>don't mark this to pdf</p> <div id="pdf"> <p><font dimension="three" colour="reddish">mark this to pdf</font></p> </div> </assemblage> </html>
```
Each I privation to bash is to mark to pdf any is recovered successful the div with an id of "pdf". This essential beryllium completed utilizing JavaScript. The "pdf" papers ought to past beryllium robotically downloaded with a filename of "foobar.pdf"
I've been utilizing jspdf to bash this, however the lone relation it has is "matter" which accepts lone drawstring values. I privation to subject HTML to jspdf, not matter.
**jsPDF is capable to usage plugins.** Successful command to change it to mark HTML, you person to see definite plugins and so person to bash the pursuing:
1. Spell to <https://github.com/MrRio/jsPDF> and obtain the newest Interpretation.
2. See the pursuing Scripts successful your task:
- jspdf.js
- jspdf.plugin.from\_html.js
- jspdf.plugin.split\_text\_to\_size.js
- jspdf.plugin.standard\_fonts\_metrics.js
If you privation to disregard definite parts, you person to grade them with an ID, which you tin past disregard successful a particular component handler of jsPDF. So your HTML ought to expression similar this:
```
<html> <assemblage> <p id="ignorePDF">don't mark this to pdf</p> <div> <p><font dimension="three" colour="reddish">mark this to pdf</font></p> </div> </assemblage> </html>
```
Past you usage the pursuing JavaScript codification to unfastened the created PDF successful a PopUp:
```
var doc = fresh jsPDF(); var elementHandler = { '#ignorePDF': relation (component, renderer) { instrument actual; } }; var origin = framework.papers.getElementsByTagName("assemblage")[zero]; doc.fromHTML( origin, 15, 15, { 'width': one hundred eighty,'elementHandlers': elementHandler }); doc.output("dataurlnewwindow");
```
For maine this created a good and tidy PDF that lone included the formation 'mark this to pdf'.
Delight line that the particular component handlers lone woody with IDs successful the actual interpretation, which is besides said successful a [GitHub Content](https://github.com/MrRio/jsPDF/issues/34). It states:
> Due to the fact that the matching is achieved towards all component successful the node actor, my tendency was to brand it arsenic accelerated arsenic imaginable. Successful that lawsuit, it meant "Lone component IDs are matched" The component IDs are inactive carried out successful jQuery kind "#id", however it does not average that each jQuery selectors are supported.
So changing '#ignorePDF' with people selectors similar '.ignorePDF' did not activity for maine. Alternatively you volition person to adhd the aforesaid handler for all and all component, which you privation to disregard similar:
```
var elementHandler = { '#ignoreElement': relation (component, renderer) { instrument actual; }, '#anotherIdToBeIgnored': relation (component, renderer) { instrument actual; } };
```
From the [examples](http://mrrio.github.io/jsPDF/examples/basic.html) it is besides said that it is imaginable to choice tags similar 'a' oregon 'li'. That mightiness beryllium a small spot to unrestrictive for the about usecases although:
> We activity particular component handlers. Registry them with jQuery-kind ID selector for both ID oregon node sanction. ("#iAmID", "div", "span" and so forth.) Location is nary activity for immoderate another kind of selectors (people, of compound) astatine this clip.
**1 precise crucial happening to adhd is that you suffer each your kind accusation (CSS). Fortunately jsPDF is capable to properly format h1, h2, h3 and many others., which was adequate for my functions. Moreover it volition lone mark matter inside matter nodes, which means that it volition not mark the values of textareas and the similar. Illustration:**
```
<assemblage> <ul> <!-- This is printed arsenic the component comprises a textnode --> <li>Mark maine!</li> </ul> <div> <!-- This is not printed due to the fact that jsPDF doesn't woody with the worth property --> <enter kind="matter" worth="Delight mark maine, excessively!"> </div> </assemblage>
```
</div></div>
