i got an ajax script that appends a new form as the user perform some actions.then i bind them to the 'submit' event. the problem is that the existing forms get bound again and now submit twice, while the newly appended forms submit once.
is there a function to check if that form has already been bound, so that i won't bind it again? in the docs there's a unbind(). But will it slow down if i append more and more forms?
I though I'd give these forums a shot. I'm having trouble figuring out how to accomplish something and was hoping someone could help. I currently have the 'enter' key bound to a submit event on several on my pages, as follows.$(document).bind('keydown','return',function(){ $("#searchSearchButton").click(); });It works well, with one problem. I've written over the alert function with my own custom alert. When the alert pops up, I try to hit 'enter' to close the alert and nothing happens because the enter key is bound to something else.
I've found that if I unbind the enter key and rebind it to close my alert box, that works fine, but I can't figure out how, after the alert box is closed, to rebind it to the previous value. I'd have to grab the existing bind value before rebinding it to close the alert box, then replace that value afterward, but I have no clue how to grab the bind key's value.
Code: var field01 = document.getElementById("Field01").value; field01[0] = field01[0].toUpperCase();
it doesnt work, the first letter of the field stays lower case BUT when I do this:
Code: alert (field01[0].toUpperCase());
then it converts the first character to uppercase, well only in the alert box, the actual one still unchanged.
so i figure thats because it needs to be triggered somehow, it wont work by assigning it. i cant use it as return. are there any trigger methods that would just let me capitalize the first letter without any pop ups or anything?
THE QUESTION: How do I get a reference to my Object when processing an event handler bound to an html element ?
CONTEXT: Sorry if it is a bit long.
I am developing a JS calendar tool. One of the requirements is that the calendar will need to display a varying number of months (1..3) depending on the calling page. Imagine 1, 2 or 3 calendar pages side by side as required.
I have built a grid object that will contain one month's dates with the day names at the top. The calendar object inherits the grid object as an array of "calendar pages" - one grid per month and the calendar provides the content for each grid. I will use the grid object for another completely different object later and so I want to use good OOP encapsulation. The grid is a table generated on the fly and is "dumb" as far as what it is used for.
I have attached an onlick event to each cell of the grid. Using OOP priciples I want the calling program (the calendar object in this case) to provide a function to handle the click and the grid object will provide to the calendar the row and column of that cell as well as the grid number (so the calendar can work out which date was clicked since it knows what the data means and the grid doesnt). Code:
problem with accessKey attribute value p (lowercase) and P(uppercase) for different html buttons.. the browser unable to differentiate between upper and lowercase key ...
i have a simple form with two buttons, and i want to trigger these buttons with keyboard keys in combination with Alt key. for example Alt + P (uppercase) should trigger button 1 and Alt + p (lowercase) should trigger button 2
Browser: IE 8.0
here is the code... ----------------------- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html>
[Code]....
here the behavior is strange, when i press Alt+P in keyboard, button1 is triggered and when i press Alt+Shift+P in keyboard, button2 is triggered ..
Is innerHTML written with this combination of upper and lowercase letters, or is it written another way? I assume if I write it with the wrong combination in the code ajax won't work.
I'm trying to implement a validation in my form, but that should not be bound to an specific field. in fact, I have three input type=text, and I need at least one of them to be filled (like a conditional 'required').
comments: The innerHTML property is needed to produce the character glyph from the entity code. If the entity string were passed to innerText(in 1st statement) then the code would remain literal.
This work-around depends on s1 being rendered before alt() is called. It will not work as immediately executed code, because element s1 would not exist yet.
cautions: Trying to style alert's display will produce error msgs. Do not use <B>, <U>, or <I> tags in the argument string. No Heading tags either.
Strange enough, an inline STYLE, setting font values, say, does not give error msg, but will not execute either. Alert ignores it.
You can use <BR> tags in the argument, which give the same result as in a direct arg to alert().
In sum, you can tell alert what characters to display, in what order, and on what line, but you cannot tell alert HOW to display them.
I've come across an issue where I've got a dynamically created popup class that despite appearing to be bound according to Visual Event does not fire on clicking the closebutton attached to it. I'm not getting any errors in firebug and by setting breakpoints I've verified we are not reaching the code to execute. Ruling out the usual suspects such as obvious spelling mistakes/ swapping out jquery versions 1.3/1.4/1.5 doesn't make any difference.where else I can look?Here is the original function:
$this.find(".close").live('click', function() { var $this = $(this); $this.parents("." + sets.popupClass).remove();
I have this boiled down to the following code: [URL]. I have two text inputs in a form, and a keydown handler to catch the arrow keys. When the focus is lost on an input, it is supposed to call the submit handler on the form. When I use the tab key, it works as expected, and calls my submit handler. However, when I use the arrow keys, it submits the form and goes to the action url, not running the alert in my custom submit handler. It's as if it either loses the bound submit handler or it calls a new default one or something.
I need to check that the user as put in at least one character between a-z upper or lowercase in a name field. They can put in whatever they like but there as to be a character a-z in the string. How shall the test expression look like?
so I spent all my time making this website [URL]html work on IE. And now it turns out it is Firefox that is trying to ruin me. I am using a simple JQuery by Sam Dunn [URL] to slide boxes on the upper left of the landing page. But in Firefox (may be it is just FFX4) it won't run. I can't fathom what can be the problem.
I then loop thru the array to assign the text and bind the click event after having created the buttons with IDs of "button_<index>".
for( var index in buttons ) { $("#button_"+index).html ( buttons[index].text ) .click( function() { clickButton( buttons[index].action ) } ); }
The text appears correctly in the button, but every button defined only fires the list bound click, in this example the action equal to'2'whether I push "Button 1" or "Button 2".My actual case has four buttons, all firing the event for the fourth button.I've tried not chaining the .click(), going thru the loop twice once for the .html and once for the .click, neither of which made a difference. If I hard code each button .click, it works fine.
I want to create an associative array dynamically pulling the index values from an array (propertyArray); Associative array is created inside create function and then returned. But after it is returned, I cant use index names to retrieve values. It returns undefined as below code shows.
Code JavaScript:
var propertyArray=["a","b","c"]; function create(){ var array=[];
I have this C# code that is connecting to database and creating a array(list)
Code:
I'm trying to pass it to a javascript function so I can then pass it to a silverlight page so I was able to create this easy javascript that show a aleart box on startup of the list(array)
Code:
But I want to do something like this and can't get it:
I am trying to understand somecode. I don't think I am understanding everything correctly. Can someone confirm or add to my understanding?
Here is the code, below is my explanation:
- CODE 1 - is saying if the the class subnav_dd is called on an anchor tag on a li, then make the function in the if statement "live". (Live in a sense binds the function to the condition, but unlike bind it allows the condition to be used more then once. ) So if the class subnav_dd is the parent, and has a class of .dis then prevent anything below it from firing. CSS - If code 1 is true, then I will only get the first li to fire, the remaining ones will not.
- CODE 2 - This one is a little tricky. Function ToggleOptions takes 3 variables (target, array, state). The condition is if the div subnav + target have siblings, then check to see how many siblings are there. Put the amount of siblings into an array, then check the state of each sibling. I don't completely the rest of it.
I think if the div subnav is called and something is found in the array then the class dis is either added or removed. Then what? I don't understand why I still need the else that adds a class to #subnav_ +.target
