  • How to get all <img> tags inside a text selection?

    - by CyberShadow
    I've looked around for a while, but there doesn't seem to be a simple way to do this. jQuery doesn't help the in least, it seems to entirely lack any support for selection or DOM ranges. Something which I hoped would be as simple as $.selection.filter('img') seems to only be doable with dozens of lines of code dealing with manually enumerating elements in ranges and browser implementation inconsistencies (though ierange helps here). Any other shortcuts?

  • JQuery class selectors like $(.someClass) are case sensitive?

    - by Justin Grant
    Given this HTML: <div class="OpenIDSelector">some text</div> Why does this JQuery selector match it on some browsers and some pages, but not on others? $('.OpenIdSelector) NOTE: I ran into this problem and solved it myself, but it was annoying and I didn't find it on StackOverflow already, so I'm posting it as a Q&A pair so someone else won't waste an hour like I did.

  • sIFR 3 randomly placing text on a single line in FF3.6

    - by bigsweater
    Hello, sIFR 3 is behaving strangely in Firefox. The actual sIFR flash element is set within a box that is 412px wide. In IE, Chrome, Safari, etc., the with of the Flash element is a consistent 412px; however, in Firefox, the Flash element is briefly as wide as the Body element, before correcting itself. When the page finishes loading, sometimes the Flash element remains that wide, breaking the layout (the Flash text flows underneath the sidebar to the right). Setting a width in the CSS for the .sIFR-flash element causes it to remain the proper 412px wide, but the text doesn't wrap at all--it just cuts off at the right edge, and the height of the flash element remains one line high. The markup is simple; it's just an h2 within a div. My sIFR code: var clerkenwell = { src: '/flash/sifr.swf' }; sIFR.activate(clerkenwell); sIFR.replace(clerkenwell, { selector: '.post h2', css: '.sIFR-root { color: #1899c4; text-transform:uppercase; font-size:30px; }', transparent: 'true', }); Setting forceWidth: 'true', just causes the same problem as using a CSS width on the .sIFR-flash element. So: how can I get the sIFR text to remain as wide as its containing element while allowing for line breaks in Firefox? Thanks for any and all help!

  • How do I extend this regex to match www.example.com in addition to http://example.com?

    - by algorithmicCoder
    I've got a regex for detecting links that works pretty well for urls of the form http://example.com, http://www.example.com etc but not for www.example.com I am trying to extend what i have so that www.foo.com also gets matched without breaking previous functionality. I tried this: /\(?\b((http|https|ftp):\/\/|)(www\.)[-A-Za-z0-9+&@#\/%?=~_()|!:,.;]*[-A-Za-z0-9+&@#\/%=~_()|]/ but this only works when www is present and doesn't work e.g. for http://example.com ...

  • How to use this piece of code in a function

    - by oliverbj
    I have this jQuery code: var vis = (function(){ var stateKey, eventKey, keys = { hidden: "visibilitychange", webkitHidden: "webkitvisibilitychange", mozHidden: "mozvisibilitychange", msHidden: "msvisibilitychange" }; for (stateKey in keys) { if (stateKey in document) { eventKey = keys[stateKey]; break; } } return function(c) { if (c) document.addEventListener(eventKey, c); return !document[stateKey]; } })(); vis(function(){ document.title = vis() ? 'Visible' : 'Not visible'; }); What it does now is to change the document title of the page. If the page is not visible, it will be changed to that and vise verca. My question is, how can I use this function like this: if page is visible{ //do something } if page is not visible{ //do something else }

  • How to retain focus on an editable html after deleting an element.

    - by Lukasz
    Hello, I have a website with design mode on (aka. content editable = true) with some basic text on it. To that site I hooked up a shortcut so that at any point in the text I can insert an input box that serves me as an autocomplete. For that input however I want it to disappear right after I hit ENTER so that I can continue typing. It is an easy task to just make the input box disappear but I always loose focus from my document. I would greatly appreciate any suggestions on how to make this work?

  • Calling an object method from an object property definition

    - by Ian
    I am trying to call an object method from an object (the same object) property definition to no avail. var objectName = { method : function() { return "boop"; }, property : this.method() }; In this example I want to assign the return value of objectName.method ("boop") to objectName.property. I have tried objectName.method(), method(), window.objectName.method(), along with the bracket notation variants of all those as well, ex. this["method"], with no luck.

  • Using input type="submit" to change content

    - by Conti
    Okay, I'm pretty sure I'm missing something very obvious here, but I just couldn't find a proper solution so far. What I'm trying to do is simple: Have a user write something into a form, have him submit the form, and write that input into a textarea on the same page. This is my code: <html><head></head> <body> <form name='registration'> <label for="input">Input:</label> <input type="text" id="input"/> <input type="submit" id="submit" value="Submit" onclick="execute()"/> </form> <div id="results"> <span>Result</span> <span><textarea cols="30" rows="5" id="resulttext" readonly="readonly"></textarea> </span> </div> <script> function execute() { var result = document.getElementById("input").value document.getElementById("resulttext").value=result; } </script> </body> </html> Now what happens if I enter something into the form is that the textarea briefly shows my input before reverting back to showing nothing. My guess is that the textarea field is only changed for the duration of the execute() function. When I change input type="submit" to a <button> everything works as intended, but I'm pretty sure I'm not supposed to do that.

  • Is there a good in-browser code editor?

    - by levik
    We've all seen in-browser rich text editors, which allow you to edit colored/styled text in a WYSIWYG manner. But what about code editors, which automatically highlight code based on language rules as you type? Think Eclipse in a textarea (but without the refactoring support). Do such things exist? I imagine scaling would be a problem - larger files would be difficult to edit efficiently.

  • mootools event listener disappears after element.innerHTML is changed

    - by baiano
    I putting together a page that will display a set of stored values. I am using mootools and AJAX calls to update the values without needing to refresh the page each time the user selects a new item from the drop down menus. the HTML each line looks something like: <div class="selections"> <input class="checkbox selector" type="checkbox" CHECKED /> <span class="b_name"> <select class="b_n selector"> <!-- options --> </select> </span> <span class="b_level"> <select class="b_l selector"> <!-- options --> </select> </span> <span class="values"> <!-- the values --> </span> In the head I have set up an event listener like: $$('.selector').addEvent('change', function(event){changeValues(this);}); My problem is that when the "b_name" select changes I have to update the list of options in the "b_level" select. I accomplish that by getting a list of the possible options from my database through a php script on another page and replacing "b_level"'s innerHTML. Once I do that, the event listener attached to "b_l selector" no longer works. I tried to resolve this issue by explicitly attaching an event listener to "b_l selector" each time "b_name" changes like so: row.getElement('.b_l').addEvent('change', function(event){changeValues(row.getElement('.b_l'));}); where 'row' is the html element 'div.selections'. It still isn't working and I have no idea what's going on. Can anyone offer a suggestion as to how I can get this resolved? or perhaps a better way to do what I'm doing. Thanks
