  • Creating a json obj from a string when working without a net connection?

    - by user246114
    Hi, I have a json object returned from a third party api, it looks like: {"version":"1.0","encoding":"UTF-8"} I'm going to be working on my project without a network connection, so I have to do everything locally. How can I create an instance of a json object locally for testing? Say I copy the above string, can I do something like: var json = null; if (debugging_locally) { json = new jsonObj('{"version":"1.0","encoding":"UTF-8"}'); } else { json = doAjaxCall(); } doStuffWithJsonObj(json); so I just want to create a json object from a stored string if debugging locally - how can I do that? Thanks

  • jQuery center multiple dynamic images in different sized containers

    - by JVK Design
    So I've found similar questions but none that answer all the questions I have and I know there must be a simple jQuery answer to this. I've got multiple images that are being dynamically placed in their own containing div that have overflow:hidden, they need to fill their containing divs and be centered(horizontally and vertically) also. The containing divs will be different sizes as well. So in short: multiple different sized images fill and center in containing div. containing divs will be different sizes. will be used multiple times on a page. Hopefully this image helps explain what I'm after. Click here to view the image. HTML I'm using but can be changed <div class="imageHolder"> <div class="first SlideImage"> <img src="..." alt="..."/> </div> <div class="second SlideImage"> <img src="..." alt="..."/> </div> <div class="third SlideImage"> <img src="..." alt="..."/> </div> </div> And the CSS .imageHandler{ float:left; width:764px; height:70px; margin:1px 0px 0px; } .imageHolder .SlideImage{ float:left; position:relative; overflow:hidden; } .imageHolder .SlideImage img{ position:absolute; } .imageHolder .first.SlideImage{ width:381px; height:339px; margin-right:1px; } .imageHolder .second.SlideImage{margin-bottom:1px;} .imageHolder .second.SlideImage, .imageHolder .third.SlideImage { width: 382px; height: 169px; } Ask me anything if this doesn't make sense, thanks in advance

  • Simplify my menu animation code

    - by zaius
    I've got a bunch of 'project' divs that I want to expand when they're clicked on. If there's already a project open, I want to hide it before I slide out the new one. I also want to stop clicks on an already open project from closing and then opening it again. Here's an example of what I mean (warning - wrote the code in the browser): $('.projects').click(function() { var clicked_project = $(this); if (clicked_project.is(':visible')) { clicked_project.height(10).slideUp(); return; } var visible_projects = $('.projects:visible'); if (visible_projects.size() > 0) { visible_projects.height(10).slideUp(function() { clicked_project.slideDown(); }); } else { clicked_project.slideDown(); } }); Really, my big issue is with the second part - it sucks that I have to use that if/else - I should just be able to make the callback run instantly if there aren't any visible_projects. I would think this would be a pretty common task, and I'm sure there's a simplification I'm missing. Any suggestions appreciated!

  • Can I define which characters are allowed to 'break' a word?

    - by zneak
    Hey guys, I'm showing up veeeery long URLs in my Safari extension. Obviously, they can't fit on a single line. Currently, word breaking rules make it so most URLs are on two lines: the first one is rather short and ends with the ? symbol, and the other is ridiculously long and contains all the rest of the GET parameters. I'd like to make it so words also break on the & symbol, without screwing up copy-paste if possible. I've tried to replace every & with &\u00ad (& + the soft hyphen character), but it's kind of weird to see the hyphen after the & when there really isn't any in the URL. I thought there was something in store with CSS3 for that kind of problem, but I can't find it. Any suggestion welcome, as long as it works with Safari.

  • How to check for redirects on ajax calls?

    - by acidzombie24
    I was looking at this answer and some other answers http://stackoverflow.com/questions/199099/how-to-manage-a-redirect-request-after-a-jquery-ajax-call/199156#199156 I can not get this to work. i check the XMLHttpRequest object in both success and complete. In both cases when there is a redirect instead of getting a 302 i get a 200 and the html for that page. How do i make it actually report the 3xx redirect instead of skipping ahead and giving me a 200?

  • "Zooming" elements on a page while keeping the centre of enlargement in the centre of the window

    - by Acorn
    I'm trying to work out how to enlarge all elements on a page, but keep the centre of enlargement in the centre of the window. Example Page (up and down arrows to resize the image, you can also drag the image around) On this page, once the image reaches the top or the left side of the window the centre of enlargement changes. It also changes when you move the image. (exactly what you would expect) I'm thinking I'd need to take a completely different approach to achieve what I want. But I'm not sure what that approach is.. Any ideas?

  • Google Chrome && (cache || memory leaks).

    - by Alexey Ogarkov
    Hello All, I have a big problem with Google Chrome and its memory. My app is displaying to user several image charts and reloads them every 10s. In the interval i have code like that var image = new Image(); var src = 'myurl/image'+new Date().getTime(); image.onload = function() { document.getElementById('myimage').src = src; image.onload = image.onabort = image.onerror = null; } image.src = src; So i have no memory leaks in Firefox and IE. Here the response headers for images Server Apache-Coyote/1.1 Vary * Cache-Control no-store (// I try no-cache, must-revalidate and so on here) Content-Type image/png Content-Length 11131 Date Mon, 31 May 2010 14:00:28 GMT Vary * taken from here In about:cache page there is no my cached images. If i enable purge-memory-button for chrome (--purge-memory-button parameter) it`s not help. Images is in PNG24. So i think that the problem is not in cache. May be Google Chrome is not releasing memory for old images. Please help. Any suggestions. Thanks.

  • Implementing prompts in text-input

    - by AntonAL
    Hi, I have a form with some text-inputs: login, password. If user sees this form the first time, input-texts should "contain" prompts, like "enter login", "enter password". If user clicks text-input, it's prompt should disappear to allow typing. I have seen various examples, that uses background image with prerendered text on it. Those images are appearing with following jQuery: $("form > :text").focus(function(){ // hide image }).blur(function(){ // show image, if text-input is still empty if ( $(this).val() == "" ) // show image with prompt }); This approach has following problems: localization is impossible need to pre-render images for various textual prompts overhead with loading images How do you overcomes such a problems ?

  • JQuery - How do I count the number of elements selected by a selector?

    - by Josh
    I am using $().fadeOut() to fade items out in a list ( < li < /li). When the list is empty I wish to hide a parent object. I plan on doing this by checking in my trigger event that fades the list if the count of the objects is 0 then hide the parent element. I can use the fadeOut callback to remove the elements if necessary. The to the point question: How do I select li tags inside a ul and then get the total count of them using jquery?

  • How to get four following text inputs after each checkbox?

    - by Richard Knop
    I am traversing checkboxes like this: $('.day').each(function() { // here I need to get the following 4 text inputs in the HTML // and set some attributes on them }); After every checkbox there are four text input fields (there are also some div, span tags for CSS around them). So inside the loop above I need to get four text input fields that follow the checkbox in the HTML source so I can set some attributes on them. How would I go about that?

  • how to dynamically (re)position an element according to the bottom of the page using JS / Jquery?

    - by jon
    Hi All, the back story: i have a tab section on a page which when navigated through displays sections (divs) of varying height. the result, is that certain inputs (which are strangely positioned for reasons i can't change) on this page reposition themselves problematically. the proposed solution: as the page height changes, have these problem inputs repositioned according to the page bottom (from which their appropriate distances are always a constant). what i'm thinking is that i need some js that does something like, page height change triggers input position from bottom to = x. there are two inputs if that's at all relevant. :) if only there was css for this (i know there is under normal circumstances, but trust me -- not in this case). thanks for your time & help i've been struggling with this for weeks!

  • allignment issue of div tag

    - by Quasar the space thing
    I am trying to create a web page where on click of a button I can add div tags. What I thought to do was that I'll create two div tags within a single div so that over all presentation will be uniform and similar to a table having two columns and multiple rows and the first column contains only label's and second column will contain textbox. Here is the JS file : var counter = 0; function create_div(type){ var dynDiv = document.createElement("div"); dynDiv.id = "divid_"+counter; dynDiv.class="main"; document.body.appendChild(dynDiv); question(); if(type == 'ADDTEXTBOX'){ ADDTEXTBOX(); } counter=counter+1; } function question(){ var question_div = document.createElement("div"); question_div.class="question"; question_div.id = "question_div_"+counter; var Question = prompt("Enter The Question here:", ""); var node=document.createTextNode(Question); question_div.appendChild(node); var element=document.getElementById("divid_"+counter); element.appendChild(question_div); } function ADDTEXTBOX(){ var answer_div = document.createElement("div"); answer_div.class="answer"; answer_div.id = "answer_div_"+counter; var answer_tag = document.createElement("input"); answer_tag.id = "answer_tag_"+counter; answer_tag.setAttribute("type", "text"); answer_tag.setAttribute("name", "textbox"); answer_div.appendChild(answer_tag); var element=document.getElementById("divid_"+counter); element.appendChild(answer_div); } Here is the css file : .question { width: 40%; height: auto; float: left; display: inline-block; text-align: justify; word-wrap:break-word; } .answer { padding-left:10%; width: 40%; height: auto; float: left; overflow: auto; word-wrap:break-word; } .main { width: auto; background-color:gray; height: auto; overflow: auto; word-wrap:break-word; } My problem is that the code is working properly but both the divisions are not coming in a straight line. after the first div prints on the screen the second divisions comes in another line. How can I make both the div's come in the same line ? Thank You. PS : should I stick with the current idea of using div or should I try some other approach ? like tables ?
