I'm trying to use iTextSharp to produce some auto-generated PDF flyers of marketing material based on HTML content stored in a database. Its working really well, but I've found something I think might be a bug in iTextSharp.
I start with a block of HTML that might contain regular HTML lists like:
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>
I run the block of HTML through HTMLWorker.ParseToList to get a list of the parsed items ready to add to the PDF.
With lists, our corporate style is to have the text in black, but the bullet point in blue. So I run through the list of elements and find those which are Lists, and set the colour of the symbol to be blue:
List<IElement> elementsList = HTMLWorker.ParseToList(new StringReader(strHtml), style);
for(int cnt = 0; cnt < elementsList.Count; cnt++)
{
IElement element = (IElement)elementsList[cnt];
if (element is List)
{
List l = (List)element;
l.Symbol.Font.Color = new BaseColor(26, 189, 201);
/* then code here which adds the list to the output column */
}
else
{
/* code which adds the element without any extra processing */
}
}
This works perfectly, only the blue colour is also applied to the text of the last item in the list (not just the bullet). As I say, only the last item in the list is affected. The other items output perfectly with blue bullet points, and black text. I can't post a picture apparently, but I've linked to a PNG below:

Just wondered if anyone had come across this before, and if so, whether there was a work around. I've tested with the latest version of iTextSharp, to make sure I'm up-to-date.
Is setting List.Symbol.Font.Color the correct way to do it? I assume so because it works for all the elements of the list, just not the very last one!
Thanks,
Steve.

I am using ion-range with pin and steps. I get the current value in the range pin, but I want to add/append some text next to it.
So far in ionic API and docs I did not find a way to modify the content from the range pin, so I am thinking on maybe appending a span via the code, but so far I know to use .append() function from jQuery.
The html of the range pin is:
<div class="range-pin" role="presentation">1</div>
So I want to show it like:
<div class="range-pin" role="presentation">1 item</div>
I know it is a bit late but if anyone comes across this question, I have found the following solution:
HTML
<ion-range id="euroRange" debounce="250" pin="true" min="0" max="50" (ionChange)="formDidUpdate()" [(ngModel)]="price" color="secondary"></ion-range>
See how I added an id called euroRange to my ion-range element.
CSS
#euroRange {
.range-pin:after {
content: " €";
}
}
Inside of the euroRage id I added .range-pin:after which means that whatever I specify should be done directly after the normal content of the pin.
With content I added a space and the € symbol.
Here is the
result.
This was my solution.
Note: I put this inside ionViewDidEnter.
this._elementRef.nativeElement
.querySelector('.range-knob-handle')
.addEventListener('pointermove', function () {
const value = this.getAttribute('aria-valuenow');
this.querySelector('.range-pin').textContent = `${value} hours`;
});
So the main thing here is that the const value is the value selected on the range. After that you can do whatever you want with it and just set the textContent of the range-pin to fix the text.
I am learning to create reports using spotfire. Could you please help me to understand the feasibility.
Is it possible to change the filters based on the previous selection(filters has to be altered based on the previous section)
For Example:
I have a following table, with three columns.
Filter1 Filter2 Data
Name Name1 test1
Age Age1 test2
Location Location1 test3
I am planning to have filter options based on the column Filter1 and Filter2.
Is it possible to create a drop down with the values "Filter1" and "Filter2"?
Is it possible to modify the list of filter options, based on the first drop down selection.
For example. if "Filter1" is selected in the drop down. The list of filter options should be "Name","Age", "Location".
if "Filter2" is selected in the drop down. The list of filter options should be "Name1","Age1", "Location1".
Thank you
We can also create a cascading drop down list through the following steps.
Create a “property Control – Drop down list” myDropDownList
Select the “Unique Column Value ” to populate the drop down list (values).
Go to “Insert -> Calculated Column”
Use a simple conditional statement something like If([Value1] = ‘${myDropDownList}’, [Value 2], NULL)
Use the newly created column in the text area filter. This will be updated based on the previous section.
Thanks.
I have a solution utilizing JavaScript to effectively toggle between hidden DIVs. I'm not aware of a way to manipulate the filter object and which column it points to in the Text Area through the API. If someone does know a way I'd love to hear it!
Here is my solution with JS:
Set up your Text Area with a Drop Down for your selection as a column selector (with columns of interest chosen through the "Select Columns..." dialogue), a label displaying that selection (we will hide this, I realize it seems redundant), and 2 filters for your 2 columns.
Right click your text area and click Edit HMTL. Utilizing the HTML below, modify your HTML to match. You will want to have the 1st DIV as your drop down, the SPAN as your label which displays that drop down's property, and then the last 2 DIVS (LETTER and NUMBER in my case) as your two filters. Make sure the DIV id name matches your column name exactly.
<DIV><SpotfireControl id="8dc9d8974bde445cab4c97d38e7908d6" /></DIV>
<SPAN id=docProp style="DISPLAY: none"><SpotfireControl id="1311015997cd476384527d91cb10eb52" /></SPAN>
<DIV id=LETTER style="DISPLAY: none"><SpotfireControl id="760ae9ffd71a4f079b792fb5f70ac8b4" /></DIV>
<DIV id=NUMBER style="DISPLAY: none"><SpotfireControl id="488ef4b1289440d5be24b0dd8cfc3896" /></DIV>
Next we will implement the JS. To do so, click the +JS button in your Edit HTML. The JS itself is below. You'll want to change my inputs of LETTER and NUMBER in the first 2 getElementById references where we set them to display:none.
filter = function(){
input = $("#docProp").text().trim() //Take the text from our hidden label and trim it from any white space.
document.getElementById("LETTER").style.display = 'none'; //Reset DIV
document.getElementById("NUMBER").style.display = 'none'; //Reset DIV
document.getElementById(input).style.display = 'block'; //Set new display
}
//Run this function every 333ms or other length of time desired to update your filters.
setInterval(filter,333)
//Larger numbers mean slower response and better performance vs. faster response and worse performance. Tune as necessary.
Alternatively instead of scanning every X milliseconds (can cause some performance drag), you can make a JS button to run it manually. e.g. $("#divIdForButtonPlacement").button().bind('click',filter)
A few images of my setup for testing are shown below. Let me know if you have any questions regarding this.
I want the user to be able to select the contents of a element by clicking it once. The code would look like this:
<div onclick="this.xyz()">...</div>
The question is: what method goes where I wrote xyz? I've searched for things like "DOM select object," but the answer is a needle hidden in a haystack of irrelevant hits (or not).
Basically you'd want:
<div onclick="var contents = this.innerText;">foo bar</div>
which would set contents equal to foo bar. Of course, this isn't exactly cross-platform compatible. Firefox expects .textContent instead of .innerText. If you're not opposed to using jquery, then
<div onclick="var contents = $(this).text()">foo bar</div>
would do just as well and be cross-platform.
Hello I'm getting crazy around a dummy problem: how to remove paragraph tags < p > that RTE (in Typo3 6.1.7) adds oafter saving some text contents. I wish to add some images here to better explain this funny thing but I can't since I've not (yet) enough reputation.
BTW I put the images on an external site:
http://s16.postimg.org/uqbu40fut/rte_ptags_1.jpg
http://s16.postimg.org/7q56roi11/rte_ptags_3.jpg
The first image is a text entered in RTE; the second image (not shown here for the same reputation matter) is the same text shown in the "<>" raw view; the last image is what I see in raw view AFTER saving the content element.
I think that I must do something in the template or in the Typoscritp settings to remove these < p > useless tags... But what ??
Those <p> tags are enabled by default because in most cases you want your Text wrapped in propper HTML markup. However, typing your question into google, gets me to this two lines of Typoscript, wich I just tested on a 6.1.7 and which seem to do the job:
tt_content.stdWrap.dataWrap >
lib.parseFunc_RTE.nonTypoTagStdWrap.encapsLines >
// Remove Class Of <p class="bodytext">
lib.parseFunc_RTE.nonTypoTagStdWrap.encapsLines.addAttributes.P.class =
// Remove P tag
tt_content.stdWrap.innerWrap >
lib.parseFunc_RTE.nonTypoTagStdWrap.encapsLines >
//Remove Extra Figure Tag of Image
tt_content.image.20.renderMethod = figure
tt_content.image.20.rendering.figure
I'm trying to find a solution to avoid CKEditor, but also the older FCKeditor strips out any
<i> tag from previously inserted content to the db.
Case:
I insert html content to the db, some content contain the <i> elements.
I do this with the CKEditor.
Everything works perfect and the content shows up on the webpage.
But when i want to edit the previously inserted content, the <i> elements are missing.
In my specific case i use:
<i class="fa-icon-fullscreen fa-icon-xxlarge main-color"></i>
Of course if i disable the editor, the content shows up just fine in the textarea.
When the protectedSource solution is used, i tags are no longer stripped, but img tags stop showing up in the WYSIWIG mode of CKEditor (I'm using 4.3.1). The solution that worked better for me is to disable removing empty i tags using CKEDITOR.dtd.$removeEmpty
For example, I added the following to the config.js
// allow i tags to be empty (for font awesome)
CKEDITOR.dtd.$removeEmpty['i'] = false;
Note: This should be placed outside the CKEDITOR.editorConfig = function( config ) function.
I found the solution for this specific problem i ran into with the <i> tag
The original answer i got from drupal forum
The fix or tweak (you name it) for it is to set the following into the ckeditors config.js:
// ALLOW <i></i>
config.protectedSource.push(/<i[^>]*><\/i>/g);
Thanks to Spasticdonkey for pointing me to the link.
Here is what works for me
add the 3 lines of code below in the same order in the drupal ckeditor profile setting
admin/config/content/ckeditor/edit/Full
ADVANCED OPTIONS >> Custom JavaScript configuration
config.allowedContent = true;
config.extraAllowedContent = 'p(*)[*]{*};div(*)[*]{*};li(*)[*]{*};ul(*)[*]{*}';
CKEDITOR.dtd.$removeEmpty.i = 0;
First line is pretty much turning off the advanced filtering
Second line is allowing ALL class (), any style {} and any attribute [*] for the p,div, li and ul.
The last line is for the empty tag...this line works with images...I have found that if you use
config.protectedSource.push(/]*></i>/g);
it strips out the tag while editing.
for 4.3 version ckeditor
in config.js (after config section) paste
CKEDITOR.dtd.$removeEmpty['b'] = false;
and write widget with code
CKEDITOR.plugins.add( 'bwcaret', {
requires: ['widget'/*, 'richcombo'*/],
icons: 'bwcaret',
init: function( editor ) {
editor.widgets.add( 'bwcaret', {
button: 'Create a caret',
template: '<b class="caret"></b>',
allowedContent: 'b(!caret)',
requiredContent: 'b(!caret)',
upcast: function( element ) {
return element.name == 'b' && element.hasClass( 'caret' );
},
});
}
});
There are two possible problems:
Read about Advanced Content Filter. CKEditor is removing elements which are not allowed, but you can extend filter's rules.
However, if the problem is that CKEditor removes empty <i> elements, then you need to find other way of using it. CKEditor is not a WYSIWYG website builder. It is a document editor, so the loaded content must have a meaning. Empty inline element does not have any meaning, therefore it is removed, because otherwise editor would not know what to do with it.
One of the possible solutions in the (near) future, will be to use Widgets system, to handle those empty elements. But for now I advice you to check the CKEDITOR.htmlDataProcessor and short guide how to use it.
i found a permanent solution for it.actually what happened ckeditor removing only blank tag.whatever the tag is, may b <i> tag or <span> tag
if you are using any icon like font-awesome,maeterlize icon etc ...
you can stop it by using below code in your config.js file
CKEDITOR.dtd.$removeEmpty.span = false;
CKEDITOR.dtd.$removeEmpty.i = false;
if you are using more blank tag then you need to add the tag name after $removeEmpty
CKEditor 4 removes emtpy tags, so here you can do trick without changing any config settings.
Replace
<i class="fa-icon-fullscreen fa-icon-xxlarge main-color"></i>
With
<i class="fa-icon-fullscreen fa-icon-xxlarge main-color"> </i>
Now <i></i> tag have content i.e. so CKEditor will not remove that tag.
