onchange

Is it possible to bind javascript (jQuery is best) event to "change" form input value somehow? I know about .change() method, but it does not trigger until you (the cursor) leave(s) the input field. I have also considered using .keyup() method but it reacts also on arrow keys and so on. I need just trigger an action every time the text in the input changes, even if it's only one letter change. Tim Down There is a simple solution, which is the HTML5 input event. It's supported in current versions of all major browsers for <input type="text"> elements and there's a simple workaround for IE < 9.

This javascript is supposed to change the drop down's HTML as well as change the content of the corresponding div's. The first click changes the dropdown html but you cant change it back as well as you lose the little arrow on the dropdown that let users know its a dropdown. The populate checkboxes doesnt populate the div because i dont know how to make javascript let me put/remove check boxes JAVASCRIPT: function changeSelection() { var x = document.getElementById("populateSelection").id; if (x == "selectionViews") { document.getElementById("dropdownMenuSelect").innerHTML = "Views"; document

Is there some way to call a function each-time the value of a variable changes, in python? Something like a listener, perhaps? Specifically, I'm referring to the case where only the variable is shared between scripts like a GAE-Session. (Which uses Cookies, Memcache, etc to share data) Example: ScriptA & ScriptB, share a session variable. When Script B changes it, SctiptA has to call a method to handle that change. Jochen Ritzel Use properties. Only mutable values can change to begin with. class Something(object): @property def some_value(self): return self._actual @some_value.setter def some

Hellp, I am working on developing an online donation site for my page. I'd like the user to have a dropdown box with payment options ($5, $10, $20, Other). I've currently set it up to where it displays an input box if the "other" option is selected; if another option is selected ($5, $10, $20) then the input box is hidden. Furthermore, donations are taken via pay-pal and I've incorporated the Pay-Pal donate button/php into the site. I've run across the following issue: because the input box is the field that populates the amount that is being donated Pay-Pal does not recognize the dropdown

I got a problem, I tried several times but result is always same, I don't know what's wrong with my code. If you click on right image, it will change to left image, but if you click on left image, it wont change to right image, why? here is code: function changeImage() { if (document.getElementById("changer").src == "imgs/left.gif") { document.getElementById("changer").src = "imgs/right.gif"; } else { document.getElementById("changer").src = "imgs/left.gif"; } } and image src code here: <img src="imgs/right.gif" id="changer" onclick="changeImage()"/></a> I need this function: click on (right

I have an input onchange that converts numbers like 05008 to 5,008.00 . I am considering expanding on this, to allow simple calculations. For example, 45*5 would be converted automatically to 225.00 . I could use a character white-list ()+/*-0123456789. , and then pass the result to eval , I think that these characters are safe to prevent any dangerous injections. That is assuming I use an appropriate try / catch , because a syntax error could be created. Is this an OK white-list, and then pass it to eval ? Do recommend a revised white-list Do you recommend a different approach (maybe there is
