Function() Declaration - With No Name - When Does It Execute
Feb 14, 2010
I've been looking all over for an explanation of this function declaration but cant find it. what it means to have a function with no name, just declared as this. When does it execute? How does it get called?
I have the following code which attaches a function to events in x number of comboboxes (x will probably always = 4, but I do not want to hard-code this). I wish to pass the value of i to the function being attached as well as the value of tempData. In other words, I want the parameters in function to be the value, not a reference variable.
In the current example, I am using the hard-coded variable ci. This I want to be replaced by a literal created when the event handler is attached (the value of the loop variable i). Also, notice that I get the filter value in the event handler (assigned to the variable ct). I would like to replace this code with the value of tempData which would also be determined when the evenet is attached (it is the same value in this case, but it keeps the onChange event from having to do this each time it runs).
I have Declared same function and two diff javascript files and both files are included in HTML page and one more same function declared in HTML code too... So problem is that, which function will execute first, i mean function in either javascript or function in HTML Code?
The function is called from a child popup window which closes the child when called. The function works well however when the child window is closed the cursor on the parent window continues as if it is trying and load something (although nothing is being loaded). Do I need some sort of end function to close the function off after it is executed?
I need to execute a function after a link to a section within the same document has been clicked and the navigation has occurred. When using the onclick event handler the JS function is executed before the navigation occurs. I can't tie it to a window.onload event since the link only navigates within the already loaded document.
I'm not having any luck searching due to not knowing what keywords to use. I looked at an explanation of bubbling vs capturing, but that doesn't appear to be what I need.
Just posted this thread a few mins ago and for some reason it got deleted? Maybe it was because of the URL shortening I used. Anyway here is an example of what I mean
I have this code which removes a class from an item on mouse out.
Code:
function mouseOut8( ) { $('.bar8') .removeClass("barover"); }
I would like to change this so that the class is removed from the item I have just moused out of instead of specifying the exact item. This is so I can use this function for multiple items. I tried replacing the '.bar8' with 'this' but it didn't work.
I have long html/CSS (no CMS or php, etc.) web pages. Some people run away when they see too much content on a page. So I hide the large lower section of the pages and have the user click anchor text to execute simple JS code to change the display from 'none' to 'block' or back to re-hide.
Code:
(BTW my research indicates that search engines do not know the difference between display='none' and normal content, or I would not be hiding content in the first place.)
Within this hidden content, I have anchor text to provide name handles
Code:
So users can click a link and go directly to that section. Within that link I include
Code:
So that works fine within a particular page. But when I want to link to an anchor on another page which is within this hidden content, the browser cannot display the anchor text because it is still hidden.
Is there a way to execute the JS code to change the DOM, changing the display to 'block' on the content of the new page?
I do not see how, because the new page isn't loaded yet, there is no DOM within the browser yet, so how can it be manipulated?
Of course if I was using php I could generate the code with the property set as desired. But for straight up html/CSS/JS pages is this possible?
I get the feeling I am missing something simple here, either a simple solution or the simple fact that this is just an inherent limitation of html.
I have been trying to work my way around this issue for some time now. I am trying to stop a marquee from scrolling as soon as the page start to load not after. I have been using this to pause the marquee with JavaScript but the command does not execute but after the page loads; after all the html loads.
With this code the marquee does stop but after the page loads completely so as the page loads the marquee start to scroll and then stops as soon as the page finishes loading but with the first image of the marquee have way out. I need to be able to load the marquee 100% stopped as the page loads so then I can use the buttons I placed to control the marquee.
My question is:
Is there ANY way to completely stop the marquee from scrolling as soon as the page loads??
how to scroll the marquee by click; meaning by every click of the mouse the marquee moves either left or right, would be even better. p.s: Noted that this code does NOT work in FF for some reason. The stop does not work and the buttons don't respond. why in FF they don't work but in GC and IE they do?
I have a javascript code which makes a word toggle links under it. For example: Before clicking on it it looks like this: Stories: then once its clicked on it looks like: Stories: story 1 story 2 story 3
How can I make it so when you click stories it creates that list and also goes to story 1. Here is the code I have: Code: <h2 style="margin-left : 25px;"><img src="/images/sort_ASC.gif" id="img_DegreeList5" alt="" /> <a href="javascript:toggleDegreeList(5);" style="color:#336699;">Teaching Tales</a></a></h2> <div id="DegreeList5" style="display:none;"> <ul><ul> <li><a href="teaching_tales1.php">Story 1</a></li> <li><a href="teaching_tales2.php">Story 2</a></li> </ul></ul> </div>
And here is the toggledegree script Code: <script type="text/javascript"> var currentDegreeList = null; function toggleDegreeList(which) { if(currentDegreeList) { document.getElementById('DegreeList'+currentDegreeList).style.display = 'none'; document.getElementById('img_DegreeList'+currentDegreeList).src = '/images/sort_ASC.gif'; } if(currentDegreeList != which) { document.getElementById('DegreeList'+which).style.display = 'block'; document.getElementById('img_DegreeList'+which).src = '/images/sort_DESC.gif'; currentDegreeList = which; } else { currentDegreeList = null; } } var submitted = false; function submitForm() { var val = (submitted) ? false : true; submitted = true; return val; } </script>
If you actually want to see the live page its here [URL].
I want to execute a javascript function when ever the user clicks the window's close button, means before closing the window I should be able to execute my function.
$("#scroll").hover(function(){ $(this).find(".front").stop().animate({ top:"184px"},500,function(){ $(this).find(".front").stop().animate({ top : "7px"}, 300); }); });
I try to make a scrolling picture. when mouse roll over the image with .front class will scroll down, but it has to come back after mouse roll out. the scroll down is working but I wrote a callback function, but it doesn't work.
html part <div id="scroll"> <a href="../images/big_html/babytracker_b.png"> <img src="../images/thumb_html/jukebox.jpg" /> <img src="../images/thumb_html/Tracker.jpg" class="front"/> </a> </div>
We're trying to enhance and optimize the forms in our projects with jQuery, but I don't know if something we want is possible. Nowadays we are using simple javascript to enable and disable elements in our forms, we have a part to execute when the document is loaded and another that is executed with the interaction of the user.
For example, we have a simple select with "Race" : "Caucassian", "African" and "Other", when the user selects something we enable or disable a textfield (where the user specifies the other race) depending of the election; and when the user saves the data and reopen the form to modify the elements, we execute a function that evaluates the value of the select (previously loaded from the database) and enable or disable the textfield.
We need to optimize this because we've got really large forms (sometimes with 400 different fields) and it would be great to do this in 1 step and have one file with the behaviours instead of doing this once for the interaction and once for the reload. I've been thinking in a way for subscribing to the onchange and execute it at the same time, but I don't know if there's any way of doing that...
I have a select form with id=px. I want to make the select execute a function every time an option is selected. I took the Change function and my code looks like this:
$("#px").change(function () { var str = ""; $("#px option:selected").each(function () { str += $(this).text() + " "; }); // $("div").text(str); - this line is changed with my function $('#selectable1 span.cica').css('font-size', str + "px"); }) .change();
It looks that srt variable is not working with my .css function. What is wrong? My markup is: <select id="px"> <option class="option" value="8" label="8">8</option> <option class="option" value="9" label="9">9</option> <option class="option" value="10" label="10">10</option> <option class="option" value="11" label="11">11</option> <option class="option" value="12" label="12">12</option> <option class="option" value="14" label="14">14</option> <option class="option" value="18" label="18">18</option> <option class="option" value="21" label="21">21</option> <option class="option" value="24" label="24">24</option> <option class="option" value="36" label="36">36</option> <option class="option" value="48" label="48">48</option> <option class="option" value="60" label="60">60</option> <option class="option" value="72" label="72">72</option> </select>
I'm trying to execute a simple JSON request using getJSON but I can't get a successful response. My code is below. If I run this I always receive an error. If I add "callback?" (making it JSONP) then I can see the correct results in Firebug but the call back function is never executed. function getResults(url) { var gptUrl = "[URL]"; $.getJSON(url, {f: "json"}, function() { alert("success"); }) .success(function() { alert("second success"); }) .error(function() { alert("error"); }) .complete(function() { alert("complete"); });}
I was wondering if someone can help me write some jQuery that would be executed after 1.8 seconds pass. Well what I want to be executed is all div tags to be shown. As$(document).ready(function() { ("div").show();});would show all div tags when the document is loaded.Is there a way I could do something like what I have written inpseudo-code$(document).wait("1800", function() { ("div").show();});
