  • What's wrong in my JavaScript code?

    - by DarkLightA
    I can't figure out what's wrong. var CarObj = function(passengers, maxLoad, wheels, doors, maxSpeed) { this.passengers = passengers; this.maxLoad = maxLoad; this.wheels = wheels; this.doors = doors; this.maxSpeed = maxSpeed; }; var ferrari = new CarObj(4, "700kg", 4, 2, "360km/h"); var output = new Array(); for (var i = 0; i < ferrari.length; i++) { for (var a in ferrari) { output[i] = a; } } document.getElementById('ELEMENTHERE').innerHTML = (output.join(" "));

  • jquery javascript module architecture on a website

    - by stephan
    I want to write a module on one html site - I will never leave the site I think about two possible concurrent basic approaches: We go into the module by use only a specific function (with specific params - everything which will happen, happen there - logic, exception handling etc) We go in by using one handler-fct, which manages some kind of action & a dataArray (depending on the action also fcts will be called - but not directly maybe for exception handling) So what you prefer?!

  • Add leading zeros to this javascript countdown script?

    - by eddjedi
    I am using the following countdown script which works great, but I can't figure out how to add leading zeros to the numbers (eg so it displays 09 instead of 9.) Can anybody help me out please? Here's the current script: function countDown(id, end, cur){ this.container = document.getElementById(id); this.endDate = new Date(end); this.curDate = new Date(cur); var context = this; var formatResults = function(day, hour, minute, second){ var displayString = [ '<div class="stat statBig">',day,'</div>', '<div class="stat statBig">',hour,'</div>', '<div class="stat statBig">',minute,'</div>', '<div class="stat statBig">',second,'</div>' ]; return displayString.join(""); } var update = function(){ context.curDate.setSeconds(context.curDate.getSeconds()+1); var timediff = (context.endDate-context.curDate)/1000; // Check if timer expired: if (timediff<0){ return context.container.innerHTML = formatResults(0,0,0,0); } var oneMinute=60; //minute unit in seconds var oneHour=60*60; //hour unit in seconds var oneDay=60*60*24; //day unit in seconds var dayfield=Math.floor(timediff/oneDay); var hourfield=Math.floor((timediff-dayfield*oneDay)/oneHour); var minutefield=Math.floor((timediff-dayfield*oneDay-hourfield*oneHour)/oneMinute); var secondfield=Math.floor((timediff-dayfield*oneDay-hourfield*oneHour-minutefield*oneMinute)); context.container.innerHTML = formatResults(dayfield, hourfield, minutefield, secondfield); // Call recursively setTimeout(update, 1000); }; // Call the recursive loop update(); }

  • JavaScript/jQuery: Follow path over page

    - by Echilon
    I need to make an animated gif 'fly over a page and follow a path. I'm thinking of using jQuery but would I be right in thinking the only way to do it is manually calculating the percentage of width/height where the shape layer should be placed, then using absolute positioning is the only way to do this? I know there are some amazing jQuery plugins available for this type of thing.

  • changing css properties via javascript

    - by tic
    I need a function to change the appearance of some elements in my html page "on the fly", but I am not able to do. The problem is that I cannot use a command like document.write ('body {background-color: #cccccc;}'); because I need to make the changes effective when the page is already loaded, using a link like <a onmouseclick="Clicker(1)" href="#">clic</a> and I cannot use a command like document.body.style.background='#cccccc'; because I do not know if it can be applied to other not so easy cases, because I need to change the appearance of elements such as td.myclass or sibling elements such as th[scope=col]+th[scope=col]+th[scope=col]. How can I do it? Thanks!

  • Javascript pass reference by value

    - by Carlos R. Batista
    Im having this weird reference issue when im trying to get a JSON file through query: var themeData; $.getJSON("json/sample.js", function(data) { themeData = data.theme; console.log(themeData.sample[0].description); }); console.log(themeData.sample[0].description); The first console.log works, the second doesnt. Im guessing because "data" already expired by the time the script gets there and themeData is just a mere pointer to "data". Is there a ways I can make sure themeData gets a duplicate of "data" and not just a pointer to it?

  • Javascript array length incorrect on array of objects

    - by Serenti
    Could someone explain this (strange) behavior? Why is the length in the first example 3 and not 2, and most importantly, why is the length in the second example 0? As long as the keys are numerical, length works. When they are not, length is 0. How can I get the correct length from the second example? Thank you. a = []; a["1"] = {"string1":"string","string2":"string"}; a["2"] = {"string1":"string","string2":"string"}; alert(a.length); // returns 3 b = []; b["key1"] = {"string1":"string","string2":"string"}; b["key2"] = {"string1":"string","string2":"string"}; alert(b.length); // returns 0

  • Javascript obfuscation help

    - by Victor
    I need some help to understand how this code was obfuscated. The code is: <a id="suggest" href="#" ajaxify="/ajax/social_graph/invite_dialog.php?class=FanManager&amp;node_id=108463912505356" class=" profile_action actionspro_a" rel="dialog-post">Suggest to Friends</a> And the obfuscation is: \x3c\x61\x20\x69\x64\x3d\x22\x73\x75\x67\x67\x65\x73\x74\x22\x20\x68\x72\x65\x66\x3d\x22\x23\x22\x20\x61\x6a\x61\x78\x69\x66\x79\x3d\x22\x2f\x61\x6a\x61\x78\x2f\x73\x6f\x63\x69\x61\x6c\x5f\x67\x72\x61\x70\x68\x2f\x69\x6e\x76\x69\x74\x65\x5f\x64\x69\x61\x6c\x6f\x67\x2e\x70\x68\x70\x3f\x63\x6c\x61\x73\x73\x3d\x46\x61\x6e\x4d\x61\x6e\x61\x67\x65\x72\x26\x61\x6d\x70\x3b\x6e\x6f\x64\x65\x5f\x69\x64\x3d\x31\x30\x38\x34\x36\x33\x39\x31\x32\x35\x30\x35\x33\x35\x36\x22\x20\x63\x6c\x61\x73\x73\x3d\x22\x20\x70\x72\x6f\x66\x69\x6c\x65\x5f\x61\x63\x74\x69\x6f\x6e\x20\x61\x63\x74\x69\x6f\x6e\x73\x70\x72\x6f\x5f\x61\x22\x20\x72\x65\x6c\x3d\x22\x64\x69\x61\x6c\x6f\x67\x2d\x70\x6f\x73\x74\x22\x3e\x53\x75\x67\x67\x65\x73\x74\x20\x74\x6f\x20\x46\x72\x69\x65\x6e\x64\x73\x3c\x2f\x61\x3e","\x73\x75\x67\x67\x65\x73\x74 Now I used unescape on the above obfuscated code to read it. What I want to know is what exactly was used to obfuscate the code like that? Basically, I need to customize the readable code to the same obfuscation. Any help would be greatly appreciated.

  • JavaScript Regex: Complicated input validation

    - by ScottSEA
    I'm trying to construct a regex to screen valid part and/or serial numbers in combination, with ranges. A valid part number is a two alpha, three digit pattern or /[A-z]{2}\d{3}/ i.e. aa123 or ZZ443 etc... A valid serial number is a five digit pattern, or /\d{5}/ 13245 or 31234 and so on. That part isn't the problem. I want combinations and ranges to be valid as well: 12345, ab123,ab234-ab245, 12346 - 12349 - the ultimate goal. Ranges and/or series of part and/or serial numbers in any combination. Note that spaces are optional when specifying a range or after a comma in a series. Note that a range of part numbers has the same two letter combination on both sides of the range (i.e. ab123 - ab239) I have been wrestling with this expression for two days now, and haven't come up with anything better than this: /^(?:[A-z]{2}\d{3}[, ]*)|(?:\d{5}[, ]*)|(?:([A-z]{2})\d{3} ?- ?\4\d{3}[, ]*)|(?:\d{5} ?- ?\d{5}[, ]*)$/ ... My Regex-Fu is weak.

  • Clever "add tag" javascript help needed

    - by Camran
    I have this function for adding options to a Select list: function addOption(selectbox, value, text, cl ) { var optn = document.createElement("OPTION"); optn.text = text; optn.value = value; if (cl==1){ optn.className = "nav_option_main"; } selectbox.options.add(optn); } I have just discovered the "optgroup" tag, but I don't know how to implement it to the drop list. The function above is called on another selectboxes "OnChange" event, to fill sub-select-box with the desired options. I don't think it should be too difficult to add the "optgroup" tag into this, or is it? Thanks and if you need more input let me know...

  • Scope of variables inside of javascript

    - by wcpro
    I have the following code sample that im trying to wrap my head around $(document).ready(function () { test("load json", function () { length = 0; // length = 0 $.getJSON("plugins/form.json", function (data) { length = data.fields.length; // length = 4 }); ok(length == 4, "length = " + length.toString()); // length = 0? wtf? }); }); the 'length' variable does not persist when the $.getJSON runs. I cant figure out if its because its asynchronous or because the variable is out of scope.

  • Javascript not registering/executing after button click

    - by rs
    I have a textbox which i convert to tinymce textbox using tinymce.js file. I'm trying to add a new script with database fields substituted based on selection made from dropdownlist to page using registerstartupscript. In page load protected sub page_load(byVal sender as object, byval e as EventArgs) handles me.load AddScriptToPage() if not page.ispostback() then session("fname") = nothing end if end sub Script Method Sub AddScriptToPage() dim _script = " c.onRenderMenu.add(function(c, m) { " & _ add_columns() & _ "}); " ClientScript.RegisterStartupScript(Me.GetType(), keyword,_script) End Sub function add_columns() as string dim ret_string = String.empty select case ddlList.selectedvalue case 1 sqlcommand = "xyz" case 2 sqlcommand = "xyz" case 3 //Load from excel sqlcommand = nothing end select if sqlcommand isnot nothing then executereader() while reader.read() ret_string = ret_string & reader("column") end while elseif session("fname") isnot nothing dt = getdatatable(session("fname").tostring()) //method that opens oledb connection and returns columns for each dr in dt.rows ret_string = ret_string & dr("column") next end if add_columns = ret_string end function When excel file is uploaded to server this event is called protected sub btnclick(byVal sender as object, byval e as EventArgs) if hasfile then 'i have custom properties set after control validation 'Upload file 'set session value with filepath session("fname") = filepath 'call js register event AddScriptToPage() end if end sub When i click upload button i'm calling AddScriptToPage, and debug it it hits AddScripttoPage event and executes it but it doesn't showup on page. It should show column names in tinymce editor but it doesn't. But when i click another button on the same page it shows (becos session has the filename). On Upload button click page flow: Page load - AddScriptToPage is executed (registers scripts with no columns) Then AddScriptToPage in btnclick event is executed (registers scripts with columns) Why is this script not getting registered even though it is executed on vb code on uploadclick event? And why does it show up after another button click and not original button click that calls this event?

  • Set z-index with javascript setTimeout()

    - by user2266261
    What I'm trying to do is to have 4 expandable divs overlapping each other with transition set in css for 0.6s. Because the expanding lasts for 0.6s I'd like to have the expanded div lose it's higher z-index after it's done collapsing, otherwise it looks silly. However, it doesn't work, the z-index remains unchanged. It's probably somethings stupid, but I just can't find it. Thanks! <div class="wrapper" style="position: relative;"> <div id="one" style="position: absolute;" onmouseover=" this.style.height='250px'; this.style.zIndex='1'; " onmouseout=" this.style.height='50px'; setTimeout(function() {this.style.zIndex='0';},600); ">blahblahblahblah</div> <div id="two" style="position: absolute;" onmouseover=" this.style.height='250px'; this.style.zIndex='1'; " onmouseout=" this.style.height='50px'; setTimeout(function() {this.style.zIndex='0';},600); ">blahblahblahblah</div> </div>

  • Variable scope in javascript

    - by Rich Bradshaw
    This is a simple question, but I can't work it out. The specifics aren't important, but here's the gist. I have some code like this: var lat = 0; var lon = 0; if (navigator.geolocation) { navigator.geolocation.getCurrentPosition(function(position) { lat = position.coords.latitude; lon = position.coords.longitude; }); } What I think it's doing is: Set lat and lon to 0 If the browser has geolocation, overwrite those variables with real values However, at the end of that chunk, lat and lon are still 0. I've tried adding vars, passing lat and lon to the function etc but with no success... How do I make this work?

  • Javascript appending onload to a popup window

    - by Hypnotic Meat
    I'm trying to append an onload event to a popup window in the following manner: var explorerWindow = window.open(PARAMS...); explorerWindow.onload = function() {window.opener.unlockObj(id);} The idea is to make the button that generates the popup window readonly, making it usable again once the popup window has loaded all of its contents. However, the event doesn't seem to be firing at all. I even changed it to the following and got nothing: explorerWindow.onload = function() {alert("bloop");} Is there something terribly wrong with my syntax or am I missing something else entirely? Also, I'm using JQuery if there are any appropriate gems there that will help in this situation. I tried the following with similar results, but I'm not so sure I got the call right: $(explorerWindow).load(function() {alert("bloop");}); Any help is greatly appreciated.
