  • Modifying DOM of a webpage

    - by Prashant Singh
    The structure of a webpage is like this :- <div id='abc'> <div class='a'>Some contents here </div> <div class='b'>Some other contents< </div> </div> My aim is to add this after the class a in above structure. <div class='a'>Some other contents here </div> So that final structure looks like this :- <div id='abc'> <div class='a'>Some contents here </div> <div class='a'>Some other contents here </div> <div class='b'>Some other contents< </div> </div> Can there be a better way to do this using DOM properties. I was thinking of naive way of parsing the content and updating. Please comment if I am unclear in asking my doubt !

  • Multi dimensional array with get image data

    - by Dave
    I'm really confused with an array im making, its gotten a bit confusing to follow but i believe its the only way for me to approach what im trying to do. My idea here is to store getImageData in an array so i can link each image to an array of data. This is how i create my array: var listObj = { id: uid, extra: [ ctx2.getImageData(abposx,abposy,imgwidth,imgheight) ] }; pixeld.push(listObj); So now im trying to run through the array "pixeld" to find the uid but i don't know how the syntax should be.... this is what i tried: for (j = (pixeld.length-1); j > -1; --j){ if(pixeld[j].extra.data[3] !==0){ //line 220 matches.push(pixeld[j].id); } } The problem is i get this error: Uncaught TypeError: Cannot read property '3' of undefined on line 220 I have marked which line is 220 in the for loop. Any one know what my mistake is ?

  • Using jQuery.get with a file up a directory?

    - by gct
    I'm using jQuery to write a simple utility app that's just run locally. It'll read from a list of files using jQuery.get and then display them along with some meta-data (which resides in a separate file). The images and meta files live in ../scored_images/*.[jpg|meta] I can load the file list with jQuery.get just fine (it's in the current directory), and I can load up the images and display them without a problem. However when I go to load the meta file for display, jQuery.get seems to silently fail. I can load them fine if the path doesn't have ../ in it. Is there a way to work around this behavior?

  • include() Why should I not use it?

    - by aliov
    I am working through an older php mysql book written in 2003. The author uses the include() function to construct html pages by including header.inc, footer.inc, main.inc files, etc. Now I find out that this is not allowed in the default ini settings, (allow_url_include is set to Off) after I got many warnings from the server. I noticed also that you can use include without the parenthesis. I tried this and it works and I get no error messages or warnings. Are the two different? That is, is include() different from include ?

  • How to use a variable in a function expression which is injected in a page?

    - by anonymous
    I'm trying to inject a function into a webpage via Chrome extension content script by: function inject(code) { var actualCode = '(' + code + ')();'; var script = document.createElement('script'); script.textContent = actualCode; (document.head||document.documentElement).appendChild(script); script.parentNode.removeChild(script); } var myObj = person; // myObj/person is passed in from elsewhere var fn = function() { alert(myObj.name); }; inject(fn); // myObj undefined My issue is, since fn is a function expression, I can't pass in myObj.personName. So my question is, how can I construct a function expression that includes a variable? Do I do some sort of string concatenation instead? I also tried to pass the object to the function, as follows: function inject(code, myObj) { var actualCode = '(' + code + ')(' + myObj +');'; ... But this did not work, and caused a "Uncaught SyntaxError: Unexpected identifier" error. Related: Building a Chrome Extension - Inject code in a page using a Content script

  • jquery next() outside of div

    - by mike
    Hi, I'm trying to use next() to toggle a div. The problem is that the "trigger" is in a different div than the one I want to toggle. An example that works: $("span.trigger").click(function(){ $(this).next("div.task_description").slideToggle("fast"); }); <span class="trigger">The trigger</span> <div class="task_description "> some content </div> But the way I need the html setup is: <div> <span class="trigger">The trigger</span> </div> <div class="task_description "> some content </div> That doesn't work... any suggestions?

  • Update one list from another

    - by lacqui
    I have two multi-select lists in HTML - one of categories, and another of items. What I want is that, when an item selected in the "category" list, everything in the "items" list from that category is also selected. For example, if "Categories" contains "Animal", "Mineral", and "Vegetable", and "Items" contains "Dog", "Cat", "Monkey", "Diamond", "Granite", "Carrot", "Tomato": If "Animal" is selected in one list, "Dog", "Cat", and "Monkey" should be selected; any other selections should remain as they are. I'm using a Symfony PHP backend on the server, if that makes any difference

  • How to calculate the latlng of a point a certain distance away from another?

    - by Rene Saarsoo
    To draw a circle on map I have a center GLatLng (A) and a radius (r) in meters. Here's a diagram: ----------- --/ \-- -/ \- / \ / \ / r \ | *-------------* \ A / B \ / \ / -\ /- --\ /-- ----------- How to calculate the GLatLng at position B? Assuming that r is parallel to the equator. Getting the radius when A and B is given is trivial using the GLatLng.distanceFrom() method - but doing it the other way around not so. Seems that I need to do some heavier math.

What code need I write to allow leftPanel to be less than the size of TreeView ? It is necessary if TreeView node's text too long.

  • Is there a simple library that will render JSON objects as trees?

    - by Robert Gould
    So, is there a VERY simple library that will render JSON objects as trees? I know that this can be done in many ways (such as YUI), but for debug purposes I'd like to simply be able to view a JSON objects I receive from a server as a tree, nothing fancy (but collapsable tree's would be a bonus). The kind of solution I'm looking for would be something like: <script source="something.js"/> <script> obj ={"hello":"world"} lib.renderJSON("someid",obj); </script> ... <div id="someid"/> Any ideas?

  • Posting New html from TINYMCE

    - by matthewb
    Seems like a simple problem, I have a form and when someone needs to edit data, the textarea that is controlled by TINYMCE loads the values, but when I change it and submit the form, the new changes are not being posted. What am I doing wrong? UPDATE How do I do it via this, or do it say on click in the editor. I am using jquery validate, this is the submit handler. $(form).ajaxSubmit({ target:'#result', success:function(){ $('html, body').animate({scrollTop:'90px'}, 500);}, clearForm: false}); }});

  • Reset after using a link with parameters

    - by CarolinaJay65
    I am using the window.location.search parameters (www.mysite.com?page=1) to direct the user to a specific page within the site. However, since those parameters are still in window.location (the browser) reset button continues to re-direct to the same page. I would like the reset button to re-direct to www.mysite.com How do I clear the .search parameters so the (browser) reset button re-directs where I want? Is it done after the page is loaded? or after the (browser) reset button has been clicked?

  • splice() not working on correctly

    - by adardesign
    I am setting a cookie for each navigation container that is clicked on. It sets an array that is joined and set the cookie value. if its clicked again then its removed from the array. It somehow buggy. It only splices after clicking on other elements. and then it behaves weird. It might be that splice is not the correct method Thanks much. var navLinkToOpen; var setNavCookie = function(value){ var isSet = false; var checkCookies = checkNavCookie() setCookieHelper = checkCookies? checkCookies.split(","): []; for(i in setCookieHelper){ if(value == setCookieHelper[i]){ setCookieHelper.splice(value,1); isSet = true; } } if(!isSet){setCookieHelper.push(value)} setCookieHelper.join(",") document.cookie = "navLinkToOpen"+"="+setCookieHelper; } var checkNavCookie = function(){ var allCookies = document.cookie.split( ';' ); for (i = 0; i < allCookies.length; i++ ){ temp = allCookies[i].split("=") if(temp[0].match("navLinkToOpen")){ var getValue = temp[1] } } return getValue || false } $(document).ready(function() { $("#LeftNav li").has("b").addClass("navHeader").not(":first").siblings("li").hide() $(".navHeader").click(function(){ $(this).toggleClass("collapsed").nextUntil("li:has('b')").slideToggle(300); setNavCookie($('.navHeader').index($(this))) return false }) var testCookies = checkNavCookie(); if(testCookies){ finalArrayValue = testCookies.split(",") for(i in finalArrayValue){ $(".navHeader").eq(finalArrayValue[i]).toggleClass("collapsed").nextUntil(".navHeader").slideToggle (0); } } });

  • How to have screen revert to BLACK between pages?

    - by user340667
    0 Hi - I tried out the Background Image Scaling script and with Cybr's update it works like magic. It SCALES the image perfectly. No distortion. BUT, my image isn't "computer friendly". I.e.: Not 1024 X 768 or even close to that. (Heck, my monitor has a wide screen, so it isn't 1024 X 768 either! Is anybody's anymore?) Anyhow, this creates a problem inasmuch as, unless I size the window from the bottom up it ends up with a white "stripe" beneath it. What I would REALLY like for it to do is have that white to be BLACK. My "usual" BG color/text etc. code is like: ""body bgcolor="#000000" text="#fcba1e" link="#0000ff" vlink="#800080" alink="#ff0000"" (Site won't let me add the arrows here.) I've tried inserting this in various places with no success. Any ideas for a workaround would surely be appreciated ! Thanks ! Bill
