How can i pass an argument as string with line break \n in EvaluateJavascript?

I'm having an issue when using the EvaluteJavascript on both Android and iOS (I'm using Xamarin).
The issue is when I want to pass a string argument to a javascript function, if that string contains special character, the js compiler will not understand.
For example:
EvaluateJavascript("updateHtml('Some Html \n Some Html')")
But if i use, this will work:
EvaluateJavascript("updateHtml('Some Html Some Html')")
So the question is how am i able to pass entire string as argument to the javascript function in EvaluateJavascript.
Thanks in advance :)

I was able to solve my issue.
I encoded my string as URL encoding like this
EvaluateJavascript('$"updateHtml({Uri.EscapeUriString("Some Html \n Some Html"'})))
Then in my javascript i just need to decode it by using:
document.getElementById("body").innerHTML = decodeURI(html);

How about using "\\n" instead of "\n" ?

Setting Danish Character Text

I am getting some strings from json. My string contains special characters like "æ" from Næstved an many more like "ø" from køkken. But When I set Text these strings to ant textview, I get my strings printed in unusual way.
Example: For køkken I get k&oslash ;kken.
I think I need to encode or decode my string somewhere but where I don,t know.
Please help.
Thanks in advance

The displayed version of your string represents an HTML encoded entity. You might want to verify that it is not coming in this way in your JSON data, but in any case, to decode it you can use the StringEscapeUtils.unescapeHtml4 method from Apache Commons Lang:
final String escaped = "køkken";
System.out.println(StringEscapeUtils.unescapeHtml4(escaped));
Output:
køkken

Did you check out the Latin Coding for your characters? I know the Ash character can be coded with æ and will show up æ in the browser.
Here is the a list of codes
Hope this helps!

How to skip image tag in html data in android?

My data in db is stored in html format along with image tags in it. So when I am getting the data from database I am removing the html tags and setting it to textview. My problem is even after removing the html tags, there is a small square box displaying in the emulator indicating that there is some image. How can I remove those square box in emulator which is an indication of image in that html data? Help me regarding this...
Thanks in advance
My Code:
textView.setText(Html.fromHtml(htmlString));

You could do a regex replace <img.+?> on htmlString.
textView.setText(Html.fromHtml(htmlString.replaceAll("<img.+?>", "")));
Untested

since images can look like:
<img ...></img>
and
<img... />
This solution will match both cases:
String htmlBody = htmlString.replaceAll("<img.+/(img)*>", "");
textView.setText(Html.fromHtml(htmlBody));

None of the answers are able to remove all possible img tags.
The most appropriate answer would be
String htmlBody = htmlString.replaceAll("(<(/)img>)|(<img.+?>)", "");
It will remove and tags both. And not remove any content between two images.

hi have a look on this example
String temp="<img>helloo</img><b> this is test</b>";
temp= temp.replace("<img>", "");
temp= temp.replace("</img>", "");
textView.setText(Html.fromHtml(temp));

How to remove html tags getting from sqlite database in android?

In my project I am getting data from sqlite database and setting that data to my textviews. But the data which I am getting contains html tags which is looking odd when I am displaying. Can we remove those html tags after getting them from database? Please help me regarding this.
Thanks in Advance.....

you can use html tags instead to remove by following statement:
textView.setText(Html.fromHtml(htmlString));

Download the JSoup library from http://jsoup.org/, and use it this way:
Jsoup.parse(html).text();
This will return a String that you can put in your textview.
