For example, if link is < a href ...> stuff </a>, so that you copy it in textfield, only string 'stuff' is copied and nothing more?
When I copy some page with links in text in redactor editor, it copies links AS links, I want only string (link name, string inside link tag) be copied, and nothing more
Have you test to add HREF LINK in deniedTags like this:
jQuery('#redactor').redactor({
deniedTags: ['a']
});
Reference
In redactor 9.1.1 use setting pastePlainText
This setting allows users to have all html tags stripped from the pasted text. Generally it is "paste as plain text" feature.
Default setting is false, to turn on, set the following:
$('#redactor').redactor({
pastePlainText: true
});

I'm writing a WinJS app that takes an HTML fragment the user has copied to the clipboard, replaces their
Later, when I go to display the .html, I create an iFrame element (using jQuery $(''), and attempt to source the .html into it, and get the following error
0x800c001c - JavaScript runtime error: Unable to add dynamic content. A script attempted to inject dynamic content, or elements previously modified dynamically, that might be unsafe. For example, using the innerHTML property to add script or malformed HTML will generate this exception. Use the toStaticHTML method to filter dynamic content, or explicitly create elements and attributes with a method such as createElement. For more information, see http://go.microsoft.com/fwlink/?LinkID=247104.
I don't get the exception if I don't base64 encoded the images, i.e. leave them intact and can display iframes on the page with the page showing images.
If I take the html after subbing the urls for base64 and run it through toStaticHTML, it removes the src= attribute completely from the tags.
I know the .html with the encoded pngs is right b/c I can open it in Chrome and it displays fine.
My question is I'm trying to figure out why it strips the src= attributes from the tags and how to fix it, for instance, creating the iframe without using jquery and some MS voodoo, or a different technique to sanitize the HTML?
So, a solution I discovered (not 100% convinced it the best and am still looking for something a little less M$ specific) is the MS Webview
http://msdn.microsoft.com/en-us/library/windows/apps/bg182879.aspx#WebView
I use some code like below (where content is the html string with base64 encoded images)
var loadHtmlSuccess = function (content) {
var webview = document.createElement("x-ms-webview");
webview.navigateToString(content);
assetItem.append(webview);
}
I believe you want to use execUnsafeLocalFunction. For example:
var target = document.getElementById('targetDIV');
MSApp.execUnsafeLocalFunction(function () {
target.innerHTML = content}
);
I know that if I add target="_blank" to the <a> tag this will cause a new window to open when the link is clicked.
But how do I add this to the <a> tag the Drupal way ?
This is a teaser title, not an anchor that I created in a block or have direct edit ability to.
Thanks all.
You can add target="_blank" using jquery, so you avoid using a non compliant tag.
$(document).ready( function() {
$('a.teaser-title-class').attr({
target: "_blank",
title: "Opens in a new window"
});
});
Change teaser-title-class with your teaser title class. You can find what class it is using "inspect element" in chrome or firefox. If teaser class isn't available, you can use selector in other ways, e.g.: $('#teaser a')
As Marius says you can use the node template file, but that involves non-compliant markup. If you use JS, then the Drupal way uses behaviors. Also you shouldn't assume $ is jQuery in D7. Here's an example:
(function ($) {
Drupal.behaviors.titleTargetModify = {
attach: function(context) {
$('h2 a:not(.titletarget-processed)', context)
.addClass('titletarget-processed')
.attr('target', '_blank');
}
};
}(jQuery));
More details
this can be changed in your theme file (usually is node.tpl.php ) and you just add the target attribute there. keep in mind that the target attribute is not xhtml compliant and you should use javascript to add the target attribute
I have used asp.net ajax html editor and i saved data in database. But now i want to retrieve it and show it in grid view. But when i retrieve that, it also shows those html tags (generated by asp.net ajax editor). So, i want to trim those tags and show plain text in grid view. How do i do that?
Thanks
Go to you db and look, how it is saved. Maybe it is save encoded. If it is not the case, you can use some simple regex to remove all those tags.
<[^<]+?>
This shows you just plain text and removes all Tags
To stripe the html tags from text you can utilize the
RegEx.Replace("str","Pattern","replacementstring "); method which there exist in
System.Text.RegularExpressions namespace
for example
Plain_Body = Regex.Replace(txtBody.Text, #"<[^>]*>", string.Empty);
here i am replacing the html specific characters with String.Empty or "" you can add additional characters if you wish to pattern like #"<[^>]*>" and spaces( ) and Ampersand(&) etc
In my markup I am using HTML title attributes which I set by the Tooltip property of various ASP.NET controls like an asp:Label. The content of those titles come from a database and I use data binding syntax, for instance:
<asp:Label ID="PersonLabel" runat="server"
Text='<%# HttpUtility.HtmlEncode(Eval("PersonShortName")) %>'
ToolTip='<%# HttpUtility.HtmlEncode(Eval("PersonFullName")) %>' />
Now, tooltips seem to be displayed as plain text on Windows and in the browsers I have tested. So the HTML-encoding is not what I really want and I am inclined to remove the encoding.
Can this be dangerous in any way if the database fields may contain script tags for example? My question is basically: Is it always guaranteed that HTML-title attributes are displayed as plain text? Are they always displayed as tooltips at all, or is it possible that some browsers (or OSs) display them in another way and allow and render HTML content in the title attributes?
Edit:
Looking at some of the answers it seems I didn't phrase my question well, so here are some additions:
If I have in the code snippet above a PersonShortName of "PM" in my database and as the PersonFullName a name with non-ASCII characters in it like Umlauts in "Peter Müller" the browser displays in the tooltip Peter Müller when I apply HttpUtility.HtmlEncode like in the code example - which is ugly.
I've also tested a simple HTML fragment like:
<span title="<script>alert('Evil script')</script>" >Hello</span>
The script in the title attribute didn't run in a browser with enabled Javascript (tested with Firefox), instead it was displayed in the tooltip as plain text. Therefore my guess was that title attributes are always rendered as plain text.
But as Felipe Alsacreations answered below there exist "rich tooltip plugins" which may render the title attribute as HTML. So in this case encoding is a good thing. But how can I know that?
Perhaps HttpUtility.HtmlEncode isn't the right solution and I have to filter only HTML tags but not encode simple special characters to make sure that the plain text is displayed correctly and to protect "rich HTML tooltips" at the same time. But it looks like a costly work - only for a simple tooltip.
Always sanitize output to the browser.
If a value like "><script>blabla</script> is inserted as a value for your fields, a user can essentially take over your entire site. It will probably make a mess when it comes to validation and correct code, but the script will still be run.
So to answer your question: No, it is not guaranteed that HTML-title attributes are displayed as plain text if the user knows what he/she is doing.
Beside security reasons:
Title attributes should always be plain text but certain JS plugins misuse them to display 'rich' tooltips (i.e. HTML code with bold text, emphasis, links and so on).
As for browsers and AFAIK they are displayed as plain text and tooltips, never displayed to those who use tabbed navigation (keyboard) and scren readers give to their users (blind and partially sighted people) many options, like reading the longest between link title and its text or always title or never ...
Surprisingly, still, no right answer in 5 years. The answer is: yes, you need to encode the title attribute, but not everything that is encoded in the innerText of the element.
The proper way to do it in asp.net if you do your own markup is:
string markup = string.Format("<div class='myClass' title='{0}'>{1}</div>",
System.Web.HttpUtility.HtmlAttributeEncode(myText),
System.Web.HttpUtility.HtmlEncode(myText));
The above will set both innerText and title of the div to myText, which is customary for elements that may contain long text but are constrained in width (as I believe the question implies).
The ToolTip property of a ASP.NET control will auto encode the value on output/rendering.
This means it is safe to set the tooltip to plain text as the page will sanitize the text on rendering.
Label1.ToolTip = "Some encoded text < Tag >"
Renders HTML output as:
<span title="Some encoded text < Tag >"></span>
If you need to use text that is already encoded, you can set the title attribute instead. The title attribute will not be automatically encoded on rendering:
Label1.Attributes("title") = "Some encoded text < Tag >"
Renders HTML output as:
<span title="Some encoded text < Tag >"></span>
Another point:
Who cares how the title attribute is rendered by a browser, when it is the presence of malicious strings in the source code that could present an issue?
It doesn't matter how it is displayed, the question is: how does it appear in the source code?
(As already stated, if you're pumping strings to the client, do something to sanitize those strings.)
I think there may be some confusion going on with this thread.
Firstly <asp:Label> is an ASP.NET Web Control. The Text and ToolTip attributes are "abstractions" of the inline content and 'title' attributes of an HTML tag respectively.
For these particular two properties Microsoft will perform the HTML Encoding for you automatically so if you set ToolTip="H&S<" then the <span> tag will be rendered as <span title="H&S<"...>. The same goes for the Text property.
NOTE: Not all properties perform automatic encoding (HTML or InnerContent properties for example)
If however you are generating HTML tags directly (Response.Write("<span...") for example) then you MUST http encode the text content and tooltip attributes content if:
Those values originate from a user / external unsanitised source or
If there is a possibility that the content may contain characters that should be escaped (& < > etc.)
Usually this means that it is safe to to:
Hardcoded content with no http characters:
Response.Write("<span title='Book Reference'>The art of zen</span>"); // SAFE
Hardcoded content with http characters that you manualle encode:
Response.Write("<span title='Book & Reference'>The art & zen</span>"); // SAFE
Dynamically sourced content:
Response.Write("<span title='"+sTitle+"'>"+sText+"</span>"); // UNSAFE
Response.Write("<span title='"+HttpUtility.HtmlEncode(sTitle)+"'>" +HttpUtility.HtmlEncode(sText)+"</span>"); // SAFE
Please help me to get text (non html/ not formatted) from ajax text editor in asp.net i am using vs 2008.
i am using AjaxControlToolkit.HTMLEditor
you can see same kind of at : ajax HtmlEditor
Well, the documentation on the page you linked to only shows that the HTMLEditor has a Content property, which is the html text, not the plain text. However, the editor itself, on the page, allows you to view either the rendered html, or the html code (the markup).
The editor uses an <iframe> to contain the rendered html. If you want to get the plain text (no html tags), you'll have to do it on the clientside. The <iframe> has an id. You could use something like jquery to do this:
var plainText = $("#iframeID body").text();
$("#someHiddenField").val(plainText);
As long as someHiddenField is an <asp:HiddenField> control, it will contain the plain text of the editor when you post back. You just need to make sure you make the above assignment after you're done editing the HTMLEditor's content, but before you actually post back.
UPDATE
I answered another similar question, and my first answer might not actually get the text of the <iframe>. Try this:
var text = $("#iframeID").contents().find("body").text();
$("#ctl00_cpMainContent_Editor1_ctl02_ctl00").contents().find("body")[0].innerHTML
