  • PHP echo in Javascript

    - by DonCroce
    I have this code: document.getElementById('root').style.left = '<?php echo $page_position[$info["os"]][$info["browser"]][0]; ?>'; document.getElementById('root').style.top = '<?php echo $page_position[$info["os"]][$info["browser"]][1]; ?>'; Why won't this work like this?

  • asp.net-mvc: javascript caching

    - by Omu
    I'm thinking whether it makes sense in order to increase the speed of the website to do some strategy of caching the js files that are being included ? one idea that I have is to do something like this: [OutputCache(Location = OutputCacheLocation.Any, Duration = 3600)] public JsController : Controller public ActionResult JQuery() { //I would have a ascx with the entire jquery script inside return View(); } and on the site.master: <%=Html.RenderAction("JQuery","JsController");

  • Getting the "unmodified" HTML document from Javascript

    - by chris_l
    Is it possible to get the source of the current HTML document, exactly as it was loaded, in text form? (i.e. not the "Generated source" after parsing and DOM manipulation.) Note: Issuing an extra AJAX request to retrieve the HTML page again is not an option in this case: The document could have changed.

  • Odd toString behavior in javascript

    - by George
    I have this small function that's behaving oddly to me. Easy enough to work around, but enough to pique my curiosity. function formatNumber(number,style) { if (typeof style == 'number') { style = style.toString(); } return (number).format(style); } The return format part is based on another function that requires the style variable to be a string to work properly, so I'm just checking if style is a number and if it is to convert it to a string. When the function above is written as is, the format function format doesn't work properly. However when I write it as simply: return (number).format(style.toString()); Everything works. Is there a difference between putting the .toString function inside the format call vs performing it before hand and setting it as the variable style?

  • Javascript adding two numbers incorrectly

    - by Scott
    Global.alert("base: " + base + ", upfront: " + upfront + ", both: " + (base + upfront)); This code above outputs this: base: 15000, upfront: 36, both: 1500036 Why is it joining the two numbers instead of adding them up? I eventually want to set the value of another field to this amount using this: mainPanel.feesPanel.initialLoanAmount.setValue(Ext.util.Format.number((base + upfront), '$0,000.00')); ...and when I try that now it turns the number into the millions instead of 15,036.00. I have no idea why. Any ideas?

  • Javascript, problem with binding an event to a div-tag

    - by Patrick
    Hello, i am trying to bind an event to a dynamically created div. function GameField(playerNumber) { this.fields = new Array(); this.player = playerNumber; this.isPlayerActive = false; this.currentRound = 0; } GameField.prototype.InitField = function(fieldNumber) { var newField = document.createElement("div"); if (fieldNumber == 0 || fieldNumber == 6 || fieldNumber == 8 || fieldNumber == 17) newField.className = 'gameCellSmall borderFull gameText gameTextAlign'; else newField.className = 'gameCellSmall borderWithoutTop gameText gameTextAlign'; newField.onclick = function() { this.DivClick('a'); } this.fields[fieldNumber] = newField; return newField; } GameField.prototype.DivClick = function(fieldNumber) { alert('Nummer: ' + fieldNumber); } Everything works perfectly, but when you click on one of the created divs, i end up with the following error message: Error: Object doesn't support this property or method. If i replace the onclick function with this, then it works: newField.onclick = function() { alert('Nummer: ' + fieldNumber); } How can i get the onclick event to fire my DivClick function instead?

  • JavaScript OOP problem

    - by Danmark
    I create windows like this: var obj = document.createElement('div'); obj.className = 'window'; obj.style.width = 300 + 'px'; obj.style.height = 200 + 'px'; obj.style.left = 30 + 'px'; obj.style.top = 200 + 'px'; //and so on and what I need is to attach some data to each window. The data will be grabbed via Ajax and displayed in the windows. How should I do it so that each window hold its own unique data? I don't need to display the whole data every time and this data would need be organized before being displayed, so I can't just add it with innerHTML. I need a way to hold it somewhere else where I could easily get it and then display it with innerHTML.

  • javascript Refresh Div.

    - by Tom
    Hi, I am using this code to refresh the data inside of the div: <script> $(function() { $("#refresh").click(function() { $("#new").load("/new.php") }) }) </script> Except it loads the who page inside of the div, instead of just the information that is inside of the div. How do I make it refresh only the data that is inside of the div? Is there a way of doing it other than putting the information for that div in a seperate page?

  • Redefine Object.defineProperty in Javascript

    - by kwicher
    I would like to learn if it is possible to redefine the "definePropery" function of the Object(.prototype) in a subclass(.prototype) so that the setter not only sets the value of the property but also eg executes an additional method. I have tried something like that: Myclass.prototype.defineProperty = function (obj, prop, meth) { Object.defineProperty.call(this, obj, prop, { get: function () { return obj[prop] }, set: function () { obj[prop] = n; alert("dev") } }) } But id does not work

  • javascript / jQuery variable problem (possibly caching issue)

    - by waitinforatrain
    Standard AJAX query with jQuery: var globalTitle = ""; var pages = ["a", "b", "c"]; for (var i = 0; i < pages.length; i++) { createpage(pages[i]); } function createpage(title) { globalTitle=title; console.log (globalTitle); //All looks good here $.ajax({ url: "createpage.php?id=" + title, context: document.body, success: success }); } The success() function uses globaltitle which is why I had to declare it global. In the success() function though console.log (globalTitle); constantly gives me "a". It's like the variable is assigned but is then cached every time success() is called. Happens in FF 4 and Chrome 8. Any thoughts?

  • A little javascript help needed here (easy).

    - by Camran
    function addOption(selectbox, val, txt){ ...... } addOption(list, "Cars", "Cars"); I need to add this in front of the text of the function: &nbsp;&nbsp;&nbsp; So that there is space coming in before the option text...Never mind what it is for, it is just confusing... I just don't know how to insert it into the js code. If I do it like this: addOption(list, "Cars", "&nbsp;&nbsp;&nbsp;Cars"); Then the &nbsp;&nbsp;&nbsp; comes into the text, so it gets displayed for the users. However I need it to be interpreted as "space"... If you don't understand let me know... How can I do this? Quotes, double quotes etc? Thanks

  • Javascript: Retrieve Object Property Names

    - by Jason
    I'm trying to write a function that needs to know the property names of an object being passed in, like so: var data = { "key1":"value1", "key2":"value2", etc} ^ i want the string value "key1" How do I retrieve the string "key1" from data? I know I can set a property dynamically like data[prop]=value but i want to know what prop is from an object passed in. If that doesn't make sense I suppose I could try to explain more. Thanks! I eventually want to do something like: for (var i = 0; i<data.length; i++) { var name = data[i].getPropertyName() <--- not a real function // do stuff }

  • javascript - Google Chrome cluttering Array generated from .split()

    - by patrick
    Given the following string: var str = "one,two,three"; If I split the string on the commas, I normally get an array, as expected: var arr = str.split(/\s*,\s*/); Trouble is that in Google Chrome (for Mac), it appends extra properties to the array. Output from Chrome's debugger: arr: Array 0: one 1: two 2: three constructor: function Array() index: undefined input: undefined length: 3 So if I iterate over the array with a for/in loop, it iterates over the new properties. Specifically the input and index properties. Using hasOwnProperty doesn't seem to help. A fix would be to do a for loop based on the length of the Array. Still I'm wondering if anyone has insight into why Chrome behaves this way. Firefox and Safari don't have this issue.
