  • What's the best way to display a blown-up image using minimal JQuery?

    - by TkTech
    The Goal: On mouseover (or :hover), enlarge the preview image by about 400% and display it in the center of the page Remove the preview when the mouse leaves The Problem: Solutions like FancyBox are too bloated in FancyBox's case it ignores width and height for image elements, which makes it useless Most of these "lightboxes" steal focus when they're called Really, I'm just looking for a simple, efficient solution. Oops - StackOverflow won't let me post images yet, mockup - http://img685.imageshack.us/img685/7649/idae.png

  • Select Elements in nested Divs using JQuery

    - by PIKP
    I have the following html markup inside a Div named item and I want to select all the elements (inside nested divs) and clear the values. As shown in following given Jquery I have managed to access elements in each Div by using.children().each(). But the the problem is .children().each()goes one level down at a time from the parent div, so I have repeated the same code block with multiple .children() to access the elements inside nested Divs, can anyone suggest me a method to do this without repeating the code for N number of nested divs . html markup <div class="item"> <input type="hidden" value="1234" name="testVal"> <div class="form-group" id="c1"> <div class="controls "> <input type="text" value="Results" name="s1" maxlength="255" id="id2"> </div> </div> <div class="form-group" id="id4"> <input type="text" value="Results" name="s12" maxlength="255" id="id225"> <div class="form-group" id="id41"> <input type="text" value="Results" name="s12" maxlength="255" id="5"> <div class="form-group" id="id42"> <input type="text" value="Results" name="s12" maxlength="255" id="5"> <div class="form-group" id="id43"> <input type="text" value="Results" name="s12" maxlength="255" id="id224"> </div> </div> </div> </div> </div> My Qjuery script var row = $(".item:first").clone(false).get(0); $(row).children().each(function () { updateElementIndex(this, prefix, formCount); if ($(this).attr('type') == 'text') { $(this).val(''); } if ($(this).attr('type') == 'hidden' && ($(this).attr('name') != 'csrfmiddlewaretoken')) { $(this).val(''); } if ($(this).attr('type') == 'file') { $(this).val(''); } if ($(this).attr('type') == 'checkbox') { $(this).attr('checked', false); } $(this).remove('a'); }); // Relabel or rename all the relevant bits $(row).children().children().each(function () { updateElementIndex(this, prefix, formCount) if ($(this).attr('type') == 'text') { $(this).val(''); } if ($(this).attr('type') == 'hidden' && ($(this).attr('name') != 'csrfmiddlewaretoken')) { $(this).val(''); } if ($(this).attr('type') == 'file') { $(this).val(''); } if ($(this).attr('type') == 'checkbox') { $(this).attr('checked', false); } $(this).remove('a'); });

  • Best way to make sure I get all available options array/loop

    - by jaz872
    OK, here is my problem. I'm looking for the best way to loop through a bunch of options to make sure that I hit all available options. Some detail. I've created a feature that allows a client to build images that are basically other images layered on top of each other. These other images are split up into different groups. They have links on the side of the image that they can click to scroll through all the different images to view them. I'm now making an automated process that is going to run the function that changes the image when a user clicks one of the links. I need to make sure that every possible combo of the different images is hit during this process. So I have an array with the number of options for each group. The current array is [3, 9, 3, 3] My question is what is the best way to loop through this to make sure that all possible options will be shown? I apologize if this seems simple for someone out there, but I'm just having trouble wrapping my head around it. Hopefully if that person is out there, they can give a helping hand :)

  • Is this possible?

    - by Stud33
    I want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well. I need this done like yesterday so please let me know. Thank You, JTW

  • cycle through list, change style every x seconds

    - by kjarsenal
    I have a simple slideshow (jQuery Cycle) that displays an image every ten seconds (7 total images). In an adjacent div, I have a list with 7 bullet points. What's the easiest way to script a method in which the css/style of the appropriate bullet point changes as its accompanying image. The idea is to have all list items displayed, but 1 highlighted every 10 seconds?

  • Getting Results from a Web SQL database

    - by andrew8088
    I'm playing around with the new Web SQL databases. Is there a way to return results from a SELECT statement? Here's my example: function getTasks (list) { db.transaction(function (tx) { list = list || 'inbox'; tx.executeSql("SELECT * FROM tasklist WHERE list = ?", [list], function (tx, results) { var retObj = [], i, len = results.rows.length; for ( i = 0; i < len; i++ ) { retObj[i] = results.rows.item(i); } return retObj; }); }); } The getTasks function is returning before the success callback does; is there a way to get the results out of the executeSql method, or do I have to do all the processing within the callback?

  • Changing class of h2 inside specific div

    - by user1985060
    I want to make it so that everytime you click on an 'h2' tag, the 'input' inside gets selected and the 'h2' tag changes background, but if another 'h2' tag is clicked, the current highlight and 'input' selection changes accordingly. problem is that I have 3 different that do the same and with my code all the 3 forms are affected rather one. How do i limit my changes to only be contained to that form. Here is some code for clarification ' <form> ... <h2 onclick="document.getElementById(1001).checked='True' $('h2').removeClass('selected'); $(this).addClass('selected'); "> CONTENT <input type="radio" name="radio" id="1001" value="1001" /> </h2> ... </form>

  • phonegap crash on "resume"

    - by fancy
    My phonegap application works great but there is a glitch when it is sent to the background or "paused". When focused is returned to the app a high percentage of the time the interface is frozen and then the application crashes a few seconds later. When relaunched it is working fine again. Could anyone provide some information as to what could be causing this and where I should start trying to debug it? Thanks very much.

  • phone number validation with added input

    - by Rkstarcass
    I recently filled out a form and when I got to the phone number textBox I noticed some really cool things going on. As I entered my number, general phone symbols were getting added automatically. Example: I start entering my area code '555' and my input was changed to 1 (555) to test what just happened I backspaced on the ) and it quickly added it back in. So my question is, how do I get this input to happen?

  • Change a link's href value based on time

    - by justSteve
    I'm coding a 'Connect to Meeting' page where i would like the link that allows attendees to join our GoToMeeting event to 'become active' 15 minutes prior to the start time. So the page users visit to see the connection info (meetingID, password) includes the start time of the meeting. I need a button ('Connect To Meeting') to change from inactive to Active when [Now() < (StartTime()-15minutes)].

  • CSS and JQuery: spaces inside image name break code of url()

    - by Shyam
    Hi, I have a page that is supposed to display a larger version of an image when hovered over a thumbnail. I have a 'div' with an ID and the JQuery code is as following: $(document).ready(function(){ $('img').hover(function() { var src = $("#im" + this.id).attr("src"); $('#viewlarge').css('backgroundImage','url(' + src +')'); return false; }); }); The images I use, are generated by a Ruby script that "generate" an image with a similar, yet different id. However, sometimes, photo's are uploaded that have "spaces" inside. My developer tools tell me that the background-image is not set correctly, yet the image path is correct and the browser don't have problems finding the image. My question is, can I somehow sanitize the url 'src', so spaces won't be a problem? I am aware of doing this server side, yet I would like to know how to do this with JQuery/JS too. Thanks!

  • Does submit() function has a callback?

    - by ecu
    Hi, I have this code: setMyCookie('name','value_1'); $('.myform').submit(); setMyCookie('name','value_2'); Problem: Webkit browsers seem to update 'MyCookie' with 'value_2' before the form gets submited, or in the exact moment it is being submited, so wrong cookie value is sent with it. I want to change cookie value to 'value_2' immediately after the form is submited so the cookie is ready for another request. The following code works fine, but I don't think using timeout() is the best solution. Maybe there is another way to solve this problem? setMyCookie('name','value_1'); $('.myform').submit(); setTimeout(function(){setMyCookie('name',value_2);},100); Thanks.

  • How to $.extend 2 objects by adding numerical values together from keys with the same name?

    - by muudless
    I currently have 2 obj and using the jquery extend function, however it's overriding value from keys with the same name. How can I add the values together instead? obj1 = {"orange":2,"apple":1, "grape":1} obj2 = {"orange":5,"apple":1, "banana":1} mergedObj = $.extend({}, obj1, obj2); var printObj = typeof JSON != "undefined" ? JSON.stringify : function(obj) { var arr = []; $.each(obj, function(key, val) { var next = key + ": "; next += $.isPlainObject(val) ? printObj(val) : val; arr.push( next ); }); return "{ " + arr.join(", ") + " }"; }; console.log('all together: '+printObj(mergedObj) ); And I get obj1 = {"orange":5,"apple":1, "grape":1, "banana":1} What I need is obj1 = {"orange":7,"apple":2, "grape":1, "banana":1}
