  • JavaScript Loop and wait for function

    - by Fluidbyte
    I have a simple single-dimension array, let's say: fruits = ["apples","bananas","oranges","peaches","plums"]; I can loop thru with with $.each() function: $.each(fruits, function(index, fruit) { showFruit(fruit); }); but I'm calling to another function which I need to finish before moving on to the next item. So, if I have a function like this: function showFruit(fruit){ $.getScript('some/script.js',function(){ // Do stuff }) } What's the best way to make sure the previous fruit has been appended before moving on?

  • Javascript: Inline function vs predefined functions

    - by glaz666
    Can any body throw me some arguments for using inline functions against passing predefined function name to some handler. I.e. which is better: (function(){ setTimeout(function(){ /*some code here*/ }, 5); })(); versus (function(){ function invokeMe() { /*code*/ } setTimeout(invokeMe, 5); })(); Strange question, but we are almost fighting in the team about this

EDIT Marcel Korpel: The value is always in the span in a div coming directly after a div containing a span with class d1, like: <div class="mov"><span class="d1">1&nbsp;Reforço</span></div><div class="dur_r">em&nbsp;<span id="timer2">0:14:55</span>&nbsp;hrs.</div>

    - by Samuel
    I was wondering, is there a way to detect if a certain image / div is loaded? For example when i am loading two heavy images and showing a loading sign at the two places the images will later occupy, is there a way to already display the first image when it's loaded while still loading the second one?

  • SharePoint Client JavaScript Documentation

    - by G N
    I'm attempting to improve the usability of a client's SharePoint deployment via JQuery; and am hitting a brick wall when trying to find any sort of documentation of what's happening in core.js (aside from painfully digging through and trying to parse any sort of meaning out of it --all 250kb of it!!!!--) Anyone have any pointers, or documentation? EDIT: Sorry, to clarify my question, i'm familiar with using JQuery with SharePoint. My question involves hooking JQuery into SharePoint's own client API. My question is inspired by this post http://www.codefornuts.com/2009/09/forcing-sharepoint-into-asynchronous.html# ; where the author is overriding methods such as "SubmitFormPost" and "STSNavigate" in order to make the UI interaction more "AJAXy".

  • JavaScript inheritance

    - by Tower
    Hi, Douglas Crockford seems to like the following inheritance approach: if (typeof Object.create !== 'function') { Object.create = function (o) { function F() {} F.prototype = o; return new F(); }; } newObject = Object.create(oldObject); It looks OK to me, but how does it differ from John Resig's simple inheritance approach? Basically it goes down to newObject = Object.create(oldObject); versus newObject = Object.extend(); And I am interested in theories. Implementation wise there does not seem to be much difference.

  • Javascript/PHP popup page problem

    - by Suezy
    I have a program in PHP that allows user to pop in a message, for confirmation from user. As seen below is the link i used. From inbox.php: echo "<a href='inbox.php' onclick=\"popup('acknowledge.php?id=$id')\"><font size=1px color=maroon>acknowledge</font></a></td>"; From acknowledge.php: if ($_POST['no']) { header("location: inbox.php"); } ?> <body bgcolor=skyblue> <center><form name=form1 method=post> <b><u> Acknowledge Message </u></b><br><br> Are you sure yout want to acknowledge this message?<br><br> <input type=button name=yes value="Yes"> &nbsp; <input type=submit name="no" value="No" onSubmit="window.close()"> </form> </center> </body> The problem is, everytime i click "no", to go back from previous page. It sets the page size the same as the popup page. It becomes smaller too. What's the problem? Answers are very much appreciated.

  • Evaluating Javascript Arrays

    - by FailBoy
    I have an array that contains an array of arrays if that makes any sense. so for example: [[1, 2, 3], [2, 3, 4], [3, 4, 5], [4, 5, 6]] I want to see whether an array exists withing the array, so if [1, 2, 3] is duplicated at all. I have tried to use the .indexOf method but it does find the duplicate. I have also tried Extjs to loop through the array manually and to evaluate each inner array, this is how I did it: var arrayToSearch = [[1, 2, 3], [2, 3, 4], [3, 4, 5], [4, 5, 6]]; var newArray = [1, 2, 3]; Ext.each(arrayToSearch, function(entry, index){ console.log(newArray, entry); if(newArray == entry){ console.log(index); }; }); This also does not detect the duplicate. the console.log will output [1, 2, 3] and [1, 2, 3] but will not recognize them as equal. I have also tried the === evaluator but obviously since == doesn't work the === wont work. I am at wits end, any suggestions.

  • Javascript check of a form, not waiting for ajax response

    - by Y.G.J
    this is a part of the check in my form function check(theform) { var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.username.value)) { alert("not valid username"); theform.username.focus(); return false; } $.ajax({ type: "POST", url: "username.asp", data: "username="+theform.username.value, success: function(msg){ username = msg; if (!username) { alert("username already in use"); return false; } } }); var re = /^\w[0-9A-Za-z]{5,19}$/; if (!re.test(theform.password.value)) { alert("not valid password"); theform.password.focus(); return false; } } for some reason of sync... it check the username then duplicated username with the ajax and not waiting for respond and jump to the password check. i don't want to insert the rest of the code to isreadystate (or what ever it is) because i might move the username duplicate check to the end... and then the function will end before the ajax anyway what should i do?

  • too much recursion in javascript with jquery mouseover

    - by Stacia
    I am a JS novice. Using some code I found here to help me with mouseover scale/rotate images but now when I try to apply it to more than one object I'm getting errors saying "too much recursion". Before the function didn't take any arguments, it just was on s_1 and it worked fine. I am tempted to just write different code for each object but that isn't very good programming practice. var over = false; $(function(){ $("#s_1").hover(function(){ over = true; swing_left_anim("#s_1"); }, function(){ over = false; }); $("#np_1").hover(function(){ over = true; swing_left_anim("np_1"); }, function(){ over = false; }); }); function swing_left_anim(obj){ $(obj).animate({ rotate: '0deg' }, { duration: 500 }); if (over) { $(obj).animate({ rotate: '25deg' }, 500, swing_right_anim(obj)); } } function swing_right_anim(obj){ $(obj).animate({ rotate: '-25deg' }, 500, swing_left_anim(obj)); }

  • Unfailing Javascript Image Preview

    - by Jason
    I have the following code that presents the user with a preview of the image they're trying to upload and works really well in FF: var img = document.createElement('img'); img.src = $('#imageUploader').get(0).files[0].getAsDataURL(); The problem is, getAsDataURL() only works in FF. Is there something similar/a workaround for this kind of functionality in Chrome (specifically)?

  • Javascript Onclicks not working?

    - by Georges Oates Larsen
    I have a jQuery application which finds a specific div, and edit's its inner HTML. As it does this, it adds several divs with onclicks designed to call a function in my JS. For some strange reason, clicking on these never works if I have a function defined in my code set to activate. However, it works fine when calling "alert("Testing");". I am quite bewildered at this as I have in the past been able to make code-generated onclicks work just fine. The only thing new here is jQuery.

  • Javascript functions Math.round(num) vs num.toFixed(0) and browser inconsistencies

    - by eft
    Edit: To clarify, the problem is how to round a number to the nearest integer. i.e. 0.5 should round to 1 and 2.5 shoud round to 3. Consider the following code: <html><head></head><body style="font-family:courier"> <script> for (var i=0;i<3;i++){ var num = i + 0.50; var output = num + " " + Math.round(num) + " " + num.toFixed(0); var node = document.createTextNode(output); var pElement = document.createElement("p"); pElement.appendChild(node); document.body.appendChild(pElement); } </script> </body></html> In Opera 9.63 I get: 0.5 1 0 1.5 2 2 2.5 3 2 In FF 3.03 I get: 0.5 1 1 1.5 2 2 2.5 3 3 In IE 7 I get: 0.5 1 0 1.5 2 2 2.5 3 3 Note the bolded results. Does this mean that toFixed(0) should be avoided?

  • How to find modal dialog opener from javascript?

    - by yapiskan
    I have a page that opens a modal dialog. After the operations done on dialog I want to refresh the opener page. But when I open the popup by using "openDialog" I cannot access to the opener by using window.opener on popup page. It appears "undefined" when I wanted to access. (I dont want to use "popup" method in this case. I want it to be a dialog by the way. using "popup" is my second plan.) What is the best practice to get rid off this issue?

  • How to not use JavaScript with in the elements events attributes but still load via AJAX

    - by thecoshman
    I am currently loading HTMl content via AJAX. I have code for things on different elements onclick attributes (and other event attributes). It does work, but I am starting to find that the code is getting rather large, and hard to read. I have also read that it is considered bad practice to have the event code 'inline' like this and that I should really do by element.onclick = foobar and have foobar defined somewhere else. I understand how with a static page it is fairly easy to do this, just have a script tag at the bottom of the page and once the page is loaded have it executed. This can then attach any and all events as you need them. But how can I get this sort of affect when loading content via AJAX. There is also the slight case that the content loaded can very depending on what is in the database, some times certain sections of HTML, such as tables of results, will not even be displayed there will be something else entirely. I can post some samples of code if any body needs them, but I have no idea what sort of things would help people with this one. I will point out, that I am using Jquery already so if it has some helpful little functions that would be rather sweet¬

  • JavaScript lazy regex for matching HTML tags

    - by Grnbeagle
    Hi, I'm having a problem writing a regular expression for matching HTML tags. I found a similar entry here, but this didn't quite work in my case. Here's my test string: <div id="div0" class="myclass">here's some text that may include whitespace</div><div id="div1" class="myclass"> and some more here </div> And here's my regex based on the aforementioned entry: <div[^>]*class="myclass">[^~]*?<\/div> Note that I need to match the first instance of <div /> with class of "myclass." The content may have carriage returns. These <div> tags won't be nested. Here's a rubular page for testing: http://rubular.com/r/vlfcikKMXk
