I need to get the selected text on a document without using JQuery. Is there a way i can like do document.selectedtext or something?
window.getSelection();
U'll need to turn it into a string after that.

I'm not sure if it's possible or not but can you run a script in Quickbase? Such as in a formula field? If so, could someone show me a very simple example? I've figured out how to create custom Dashboards using jQuery so I assume we could do something similar on form/table.
There are two ways you could try to accomplish this. You can use Javascript in URL and Formula URL fields. This will make the link button pop up a window that says "Hello World".
"javascript:alert(\"Hello World\");void(0);"
You can also load a page that you've created using Dan Diebolt's image onload technique. I can't find his original post, but you use the onload event of an image tag to load a .js file. In this example it's a page in the same application named module.js that is being loaded using a Formula Text field with HTML enabled.
"<img qbu=\"module\" src=\"/i/clear2x2.gif\" onload=\"javascript:if(typeof QBU=='undefined'){QBU={};$.getScript('" & URLRoot() & "db/" & Dbid() & ?a=dbpage&pagename=module.js&rand='+Math.random())}\">"
The corresponding module.js file might look something like this:
(function(){
alert("Hello World");
})();
You can take this as far as you'd like from writing functions in module.js that you call from Formula URL Fields to injecting your own HTML into the DOM (though Quickbase recommends you do not do that). My favorite trick is to add <span id="somethingUnique"></span> either in the form builder or a text field with HTML enabled and use that to inject my custom buttons or data.
I am using DHTMLX, and I have output that goes to a div. The text gets into the div using "attachHTMLString", but after it's in that div, I don't know how to access it.
I'm used to using jQuery where you can assign an ID or class and traverse the DOM and get it. With DHTMLX, it's like jQuery's powers are useless. I just cannot get the data that is right in front of me.
I'm looking for something like:
var divText = dhtmlxElement.getText();
What's the secret to traversing the DHTMLX elements?
I just figured out, the way to do it is to give the element an ID when it's created. Later, you can just call it out by ID.
What apparently does NOT work is to refer to the element on the page by its DHTMLX name and try to "get" it, or capture its text.
But what component are you asking about?
I.e. you can really get the text of tree node by ID...
var text = tree.getItemText("itemId");
And many other components provide this feature
I am trying to create a formatted text field that will have its contents then parsed into a Ruby Date object. I think I have the logic for taking a value from a text field and turning that into a date, but I can't figure out the formatting part.
I want a text field that would already have separators in it by default, that the user could not overwrite. So I would want the text field to look like:
__/__/__
And when they tab into the field, the text they type fills in the spaces instead of overwriting everything in there.
Thanks!
not sure about the ruby but you can use jQuery like so:
http://digitalbush.com/projects/masked-input-plugin/
jQuery(function($){
$("#key").mask("aaaaa-aaaaa-aaaaa-aaaaa-aaaaa");
});
and simply use <noscript> in your page header to make sure anyone's viewing your page has the javascript enabled.
Fairly new to CKEditor here. I'm aware that you need to call the updateElement() method for CKEditor to send the current editor content to the related textarea element. From there, you can call the getData() function to get the content. (Although I don't understand why there are two steps to get the editor content, instead of one.)
However, I want to get the current content directly from the editor, without changing the related textarea content. Is there a CKEditor method to achieve that, or is it a case of using jQuery to find the editor content?
The getData method will return the raw HTML from the editor.
I have a text area in which I am trying to add youtube embed code and other HTML tags. $this->input->post is converting the <iframe> tags to < and > respectively but not the <h1> and <h2> tags.
Any idea how I can store these values?
If you only have a small number of forms that you need to allow iframes in, I would just write a function to restore the iframe (while validating that it's a valid YouTube embed code).
You can also turn off global_xss_filtering in your config (or not implement it if you're using it), but that's not the ideal solution (turning off all of your security to get one thing to work is generally a horrible idea).
$config['global_xss_filtering'] = FALSE;
To see all of the tags that get filtered out, look in the CI_Input class and search for the '$naughty' variable. You'll see a pipe-delimited list (don't change anything in this class).
Why don't you avoid CIs auto sanitizing and use something like htmlspecialchars($_POST['var']); ? Or make a helper function for sanitizing youtube urls...
Or you could either just ask for the video ID code or parse the code from what you are getting.
This would let you use both the URL or the embed code.
Also storing just the ID takes less space in you database, and you could write a helper function to output the embed code/url.
In this case, use $_POST instead of $this->input->post to get the original text area value, and then use HTML Purifier to clean the contents without losing the <iframe> tag you want.
You will need to check HTML Purifier documentation for details. Please, check this specific documentation page about "Embedding YouTube Videos".
