  • Example from: "Javascript - The Good Parts"

    - by Matrym
    What "ugliness" does the following solve? There's something I'm not getting, and I'd appreciate help understanding what it is. For example, by augmenting Function.prototype, we can make a method available to all functions: Function.prototype.method = function (name, func) { this.prototype[name] = func; return this; }; By augmenting Function.prototype with a method method, we no longer have to type the name of the prototype property. That bit of ugliness can now be hidden.

  • Can't find the error in my javascript code

    - by Olivier
    This js program should display the first 100 prime numbers, but instead it crashes each and every time and I can't find the error! Could someone point me towards the best way to debug js code?! Thank you! // initialisation of the array p holding the first 100 prime numbers var p = []; // set the first prime number to 2 p.push(2); // find the first 100 prime numbers and place them in the array p var i = 3; while (p.length < 100) { var prime = true; loop: for (var item in p){ if (i%item === 0){ prime = false; break loop; } } if (prime) p.push(i); i = i + 2; } // display the first 100 prime numbers found var i=1; for (var item in p){ document.writeln(i,item); i++; }

  • Using JQuery replaceWith with a JavaScript Variable

    - by JJ56
    Here's my html: <div class="timer">Not Started</div> And JS/JQ: var seconds = 10; var minutes = 0; setTimeout("updateTimer()", 1000); function updateTimer() { if (seconds == 0 && minutes != 0) { minutes -= minutes; seconds = 59; alert (seconds); } else if (seconds == 1 && minutes == 0) { alert ('done'); } else { seconds = seconds - 1; //alert (seconds); $(".timer").replaceWith(seconds); } setTimeout("updateTimer()", 1000); } Instead of replacing Not Started with 10, 9, 8..., Not Started disappears.

  • After .load() Reset Textbox with User Entered Value using JavaScript and jQuery

    - by Aaron Salazar
    My function below calls a partial view after a user enters a filter-by string into the text box '#DocId'. When the user is done typing, the partial view is displayed with filtered data. Since my textbox needs to be in the partial view, when user is done entering a filter-by string and is shown the filtered data, the textbox is reset and the user entered data is lost. How can I set the value of the textbox back to the user entered string after the partial view is displayed? I'm pretty sure I need to use .val() but I can't seem to get this to work. $(function() { $('#DocId').live('keyup', function() { clearTimeout($.data(this, 'timer')); var val = $(this).val(); var wait = setTimeout(function() { $('#tableContent').load('/CurReport/TableResults', { filter: val }, 500) }, 500); $(this).data('timer', wait); }); }); Thank you, Aaron

  • Sending information between JavaScript and Web Services using AJAX

    - by COB-CSU-AM
    Alright so I'm using Microsoft's Web Services and AJAX to get information from a SQL database for use with java script on the client side. And I'm wondering what the best method is. Before I started working on the project, the web services were setup to return a C# List filled with some objects. Those objects variables (ints, strings, etc.) contain the data I want to use. Of course, java script can't do much with this, to the best of my knowledge. I then modified the web service to return a 2D Array, but java script got confused, and to the best of my knowledge can't handle 2D array's returned from C#. I then tried to use a regular array, but then a found the length property of an array in JS doesn't carry over, so I couldn't preform a for loop through all the items, because there wasn't anyway of knowing how many elements there were. The only other thing I can thing of is returning a string with special char's to separate the data, but this seems way too convoluted. Any suggestions? Thanks in advance!

  • Javascript - proper getAttributeNode on IE6+

    - by Darrow
    I have a regular input box (no onchange attribute). <input type="text" id="bar" name="bar" /> For some reason, IE6+ does returns [object], while FF and Chrome returns null. if ((elem.getAttributeNode('onchange')) != null) elem.onchange(); I did also try as: if (typeof(elem.onchange) !== 'undefined') elem.onchange(); What would be the proper cross-browser way to check if the element has the attribute? Thanks

  • Retrieve text from external HTML/asp page with JavaScript

    - by Rotem
    Hi, I am using an external asp page (On the company's server - not related to me beside the fact that I'm using it for my job). The asp page has one query in it, I'm writing something in it and it gives me some information. In the information there is a certain line with constant header (let's assume 'HEADER'), I want to build an HTA that pulls the line that contains 'HEADER' to my HTA and display only this line. I think that this isn't possible without any server interaction, but I'm asking anyway. Can someone think of a way doing it? Thanks, Rotem

  • Javascript how can I trigger an event that was prevented

    - by Mike Robinson
    In my app a user clicks a link to another page. I'd like to track that in Omniture with a custom event, so I've bound the omniture s.t() event to the click event. How can I make certain the event fires before the next page is requested? I've considered event.preventDefault() on the click event of the link, but I actually want the original event to occur, just not immediately.

  • javascript instanceof get type from string name

    - by dcp
    Let's say I have this (assume the name variable is "receiver"): if (!(receiver instanceof com.HTMLReceiver)) { throw new com.IllegalArgumentException( name + " is not an instance of com.HTMLReceiver."); } I'd like to factor this code out into a common method so I could call it like this: Helper.checkInstance(receiver, "com.HTMLReceiver"); But I don't know of a way to convert the com.HTMLReceiver from a string to its actual type so I can use instanceof on it. Is there a way?

  • JavaScript loop stops on "localStorage.removeItem"

    - by user1755603
    Why is the "localStorage.removeItem" stopping the loop? If I remove "localStorage.removeItem" and only leave the "alert", it loops though whole thing, but with "localStorage.removeItem" it stops on the first match. function removeTask() { for (i=0; i < localStorage.length; i++){ checkbox = document.getElementById('utford'+i); if (checkbox.checked == true) { alert(i); localStorage.removeItem(localStorage.key(i)); } } printList(); }

  • JavaScript - Efficiently find all elements containing one of a large set of strings

    - by noah
    I have a set of strings and I need to find all all of the occurrences in an HTML document. Where the string occurs is important because I need to handle each case differently: String is all or part of an attribute. e.g., the string is foo: <input value="foo"> - Add class ATTR to the element. String is the full text of an element. e.g., <button>foo</button> - Add class TEXT to the element. String is inline in the text of an element. e.g., <p>I love foo</p> - Wrap the text in a span tag with class TEXT. Also, I need to match the longest string first. e.g., if I have foo and foobar, then <p>I love foobar</p> should become <p>I love <span class="TEXT">foobar</span></p>, not <p>I love <span class="TEXT">foo</span>bar</p>. The inline text is easy enough: Sort the strings descending by length and find and replace each in document.body.innerHTML with <span class="TEXT">$1</span>, although I'm not sure if that is the most efficient way to go. For the attributes, I can do something like this: sortedStrings.each(function(it) { document.body.innerHTML.replace(new RegExp('(\S+?)="[^"]*'+escapeRegExChars(it)+'[^"]*"','g'),function(s,attr) { $('[+attr+'*='+it+']').addClass('ATTR'); }); }); Again, that seems inefficient. Lastly, for the full text elements, a depth first search of the document that compares the innerHTML to each string will work, but for a large number of strings, it seems very inefficient. Any answer that offers performance improvements gets an upvote :)

  • HTML/Javascript Strange behavior with input field and TABBING

    - by Berlin Brown
    I have a strange error where if a user enters in data, say first name and then tabs, the text in the field is highlighted/selected as opposed to moving to the next. So, a person may type the first name and then tab to the next input item, text is selected and then they hit a character and now the name they typed in is deleted. If I use the default [input] tags, the tab works properly. But in the code below, with keyup, that may change the tabbing behavior. How can I get my code where it won't select the text. This is replicated in Firefox and Internet Explorer. function enableSearch(lnameObj) { var goButtonObj = document.getElementById('goButton'); var nextButtonObj = document.getElementById('nextButton'); var lastName = lnameObj.value; if (lastName == "") { goButtonObj.disabled = true; } else { goButtonObj.disabled = false; } } <input type="text" size="12" name="lastname" onKeyUp="return enableSearch(this);" value="">

  • Confirm box always displays first (javascript, jQuery, .Net)

    - by Jan-Frederik Carl
    Hello, I have a jQuery-Script to accomplish the following tasks: if a gridview in my form contains a row with a certain id, it has to be marked red. a confirm dialogue has to pop up to ask the user if he wants to do this or that. I built this code: if (response == "EntryInList") { $('#entryListContainer div table tbody tr').each(function() { if ($(this).attr('id') == 'entry_' + $('#<%= txtProductNumber.ClientID %>').val()) { $(this).css("color", "red"); } } ); if (!confirm("Entry already exists. Really overwrite?")) { jQuery('#<%= txtProductNumber.ClientID %>').val(''); jQuery('#<%= txtCount.ClientID %>').val(''); jQuery('#<%= txtProductNumber.ClientID %>').focus(); return false; } } As a result, the confirm box pops up first, without the row being turned red. Only after using the box, it becomes red. How would I get the row to be turned red at once? Another of my problems is that the confirm box denies my page to be scrolled down. But I would like to do this if the gridview is longer than the entire page.

  • javascript watching for variable change via a timer

    - by DA
    I have a slide show where every 10 seconds the next image loads. Once an image loads, it waits 10 seconds (setTimeout) and then calls a function which fades it out, then calls the function again to fade in the next image. It repeats indefinitely. This works. However, at times, I'm going to want to over-ride this "function1 call - pause - function2 call - function1 call" loop outside of this function (for instance, I may click on a slide # and want to jump directly to that slide and cancel the current pause). One solution seems to be to set up a variable, allow other events to change that variable and then in my original function chain, check for any changes before continuing the loop. I have this set up: var ping = 500; var pausetime = 10000; for(i=0; i<=pausetime; i=i+ping){ setTimeout(function(){ console.log(gocheckthevariable()); console.log(i); pseudoIf('the variable is true AND the timer is done then...do the next thing') },i) } The idea is that I'd like to pause for 10 seconds. During this pause, every half second I'll check to see if this should be stopped. The above will write out to the console the following every half second: true 10000 true 10000 true 10000 etc... But what I want/need is this: true 0 true 500 true 1000 etc... The basic problem is that the for loop executes before each of the set timeouts. While I can check the value of the variable every half second, I can't match that against the current loop index. I'm sure this is a common issue, but I'm at a loss what I should actually be searching for.

  • Javascript: Remove checked status from disabled input (already checked)

    Im trying to make this function to check an element and if its checked, or not, add or remove respective className. Also, if the element is disabled but is checked, it should un-check it and remove the className('yes') function init() { $(document.body).select('input').each(function(element) { if (!element.checked) { element.up().removeClassName('yes'); } else { element.up().addClassName('yes'); } if (element.checked && element.disabled) { element.checked = false; element.up().removeClassName('yes') } }); } Right now, the last part, is not working, no effect

  • Javascript/jQuery get external CSS value

    - by Acorn
    Is it possible to get a value from the external CSS of a page if the element that the style refers to has not been generated yet? (the element is to be generated dynamically). The jQuery method I've seen is $('element').css('property','value');, but this relies on element being on the page. Is there a way of finding out what the property is set to within the CSS rather than the computed style of an element?
