  • Enable/Disable Input based on selection (jQuery)

    - by Nimbuz
    <select name="state" class="select" id="state"> <option value="something">Something</option> <option value="other">Other</option> </select> <input type="text" name="province" class="text" id="province" /> jQuery $('#state').change(function () { if ($('#state Other:selected').text() == "Other"){ $('#province').attr('disabled', false); alert(1); } else { alert(2); } }); Doesn't seem to work. I must be doing something wrong.

  • Uncaught TypeError: Property 'dist2' of object [object Object] is not a function

    - by Radu Vlad
    I have this functions that should return me the distance from point p to segment line v-w. The problem i have is after some time i receive the following error: Uncaught TypeError: Property 'dist2' of object [object Object] is not a function. I receive it in distToSegmentSquared directly,not even calling the function dist2().Is it any other dist2() anywhere in jquery?I found none... function sqr(x) { return x * x; } function dist2(v, w) { console.log(v); console.log(w); return sqr(v.x - w.x) + sqr(v.y - w.y); } function distToSegmentSquared(p, v, w) { var l2 = dist2(v, w); if (l2 == 0) return dist2(p, v); var t = ((p.x - v.x) * (w.x - v.x) + (p.y - v.y) * (w.y - v.y)) / l2; if (t < 0) return dist2(p, v); if (t > 1) return dist2(p, w); return dist2(p, {x: v.x + t * (w.x - v.x), y: v.y + t * (w.y - v.y)}); } function distToSegment(p, v, w) { return Math.sqrt(distToSegmentSquared(p, v, w)); } The values that are given in for that error are: p: Object x: 461 y: 333 v: Object x: 80 y: 120 w: Object x: 260 y: 120

  • Is canvas security model ignoring access-control-allow-origin headers?

    - by luklatlug
    It seems that even if you set the access-control-allow-origin header to allow access from mydomain.org to an image hosted on domain example.org, the canvas' origin-clean flag gets set to false, and trying to manipulate that image's pixel data will trigger a security exception. Shouldn't canvas' obey the access-control-allow-origin header and allow access to image's data without throwing an exception?

  • Append before parent after getSelection()

    - by sanceray3
    Hi all, I have one question. I try to develop a little WYSIWYG editor. I would like create a <h1> button which allows me to generate a <h1> title (by clicking on button after text selection in <p> element). I obtain the selection with window.getSelection().... But now, I would like to put my append("<h1>my text selected</h1>") just before the <p>. It’s my problem, because my <p> elements don’t have id or class. So do you know a means to put my append just before the <p> where my text has been selected? I don’t know if with my bad English you’ll understand me! Thanks very much for your help.

  • Next/Previous click jQuery UI

    - by madjester
    I am trying to add next/previous buttons on a button click using the jQuery UI Slider. I found this code... $("#down").click(function() { var s = $("#slider"), val = s.slider("value"), step = s.slider("option", "step"); s.slider("value", val - step); }); $("#up").click(function() { var s = $("#slider"), val = s.slider("value"), step = s.slider("option", "step"); s.slider("value", val + step); }); Here: http://osdir.com/ml/jquery-ui/2009-03/msg00617.html However this only changes the value of the Slider, moving the slider handle, but it doesn't actually slide the element. Little help?

  • jQuery plugins: How can I stop divs from overlapping?

    - by anir
    I'm using Masonry and Embedly plugin to display embedded content, I've put together an example in jsfiddle.net/anir/pBtbb/3/ It appears the Masonry plugin loads first and it causes the overlapping problem (they only show correctly when you resize the result window) I've read that I could use callback functions or retrigger Masonry once embedly has finished rendering content, but I don't know how to do it. Can you help me? Is there any other solution to fix this?

  • IE showing hidden div under certain circumstances

    - by karola
    After googling around and finding a lot of ie bugs I still did not find a description of the problem I have. The initial situation is a standard one. We have a tooltip which is actually a hidden div that will be displayed on mouseover at a given location. The div is hidden with display:none and contains a table with the content. We tried different libraries for showing the div (scriptaculous and jQuery Cluetip) but the effect is the same. The problem: Everything is fine as long as the contents fits the width of my window. But when I resize it until the horizontal scrollbar is activated the content of the hidden div will be shown at the end of the page when the tooltip is activated. This is really strange as it happens only under these premises. When more than one tooltip is involved the browser might even crash (and under Vista takes the whole system with him duh). I know it's a bit complicated to explain but I hope that someone at least had heard of that bug and can point me into the right direction.

  • jquery next siblings

    - by Contra
    Hi stackoverflow! (first post!) Ive been trying to get this problem solved, but I cant seem to figure it out without some serious workarounds. if I have the following html code: <ul> <li class="parent"> headertext </li> <li> text </li> <li> text </li> <li> text </li> <li class="parent"> headertext </li> <li> text </li> <li> text </li> </ul> Now, how do I now just select the li's following the first parent (or second, for that matter)? Basically selecting an li with class=parent and the following siblings until it reaches another li with the parent class. I could restructure the list with nested lists, but I dont want to do that. Any suggestions?

  • Rails: How to preload a message to user

    - by Michael
    I have a Rails based prelaunch site that has some rotating background images (which are important for selling the idea of the site) that are taking too long to load, such that the users are leaving the site before they load. The only thing they're seeing is the email submission box. What's a good way to show a message to the users that the site will take some time to load but then have that message disappear after a reasonable period of time. I'm guessing a jQuery fadeOut() with a timer, but I'm not sure how long to set the timer for, because I'm not sure at what time it would start counting. Any suggestions?

  • referencing desired objects in namespaced functions

    - by RyOnLife
    I'm having trouble referencing the desired object when I've namespaced functions. No problems here: obj.test = function() { // this == obj } But I'm getting tripped up when I namespace: obj.namespace.test = function() { // this == namespace } In the latter example, I know this references namespace, but I want to reference obj. How can I do it?

  • jquery: i have to use parseInt() even when deal with numbers, why?

    - by Syom
    i have the following script <select id="select1"> <option value="1">1day</option> <option value="2">2day</option> <option value="3">3day</option> </select> <select id="select2"> <option value="1">1day</option> <option value="2">2day</option> <option value="3">3day</option> </select> and jquery $("#select2").change(function() { var max_value = parseInt($("#select2 :selected").val()); var min_value = parseInt($("#select1 :selected").val()); if(max_value < min_value) { $("#select1").val($(this).val()); } }); and now, what i can't understand anyway - if values of option elements are integer numbers, why i have to use parseInt()? in some cases it doesn't work without parseInt(). Thanks

  • JQuery .get() only passing first two data parameters in url

    - by The.Anti.9
    I have a $.get() call to a PHP page that takes 4 GET parameters. For some reason, despite giving the $.get() call all 4, it only passes the first two. When I look at the dev console in chrome, it shows the URL that gets called, and it only passes action and dbname. Heres the code: $.get('util/util.php', { action: 'start', dbname: db, url: starturl, crawldepth: depth }, function(data) { if (data == 'true') { status = 1; $('#0').append(starturl + "<ul></ul>"); $('#gobutton').hide(); $('#loading').show("slow"); while(status == 1) { setTimeout("update()",10000); } } else { show_error("Form data incomplete!"); } }); and heres the URL that I see in the developer console: http://localhost/pci/util/util.php?action=start&dbname=1hkxorr9ve1kuap2.db
