I'm use prototype quite a lot for ajax calls, but have always used inline onclicks. I'm trying to be less obtrusive by creating event handlers/listeners.I used to do this with the aid of pHp to place arguments into the function (usually via 'while loop'):
I haven't come across an exampe that would enable me to pass data to my event handler.For example, if I click a button I want it to pass the value of an adjacent text input to my handler.
I know in different languages (VB.Net,C++,C#) how to pass an argument to function in this code: <html> <head> <script language="Javascript"> <!-- hide function openNewWindow() { popupWin = window.open('[URL]', 'open_window', 'menubar, toolbar, location, directories, status, scrollbars, resizable, dependent, width=640, height=480, left=0, top=0') } done hiding --> </script></head><body> <a href="javascript:openNewWindow();">return to front page</a> </body></html>
I need to add several links in my page, so I need to pass indexes from links to main function, so I can open images in specific folder with indexes filenames. For example in vb Subname("text_to_pass_to_SubName") Public Sub SubName(ByVal function_text as string) End Sub
I use addEventListener and I cannot (or at least don't know how) pass arguments to the function.
Let's say we have a function: function warning(arg1, arg2) {alert('Argument 1: ' + arg1 + ', Argument2: ' + arg2 + '.');}
It's possible to have: onclick="warning('my argument 1', 'my argument 1');" as an html attribut.
But I think it's not posible to do it like this (still the same function): el.addEventListener("click", warning('my argument 1', 'my argument 1'), false);
I have a function which can be called with an unlimited number of arguments.
I want to call another function with exactly the same arguments. I know I can get the arguments in the arguments object, and as such also in an array, but how do you pass the elements of an array to another function as parameters?
I would like to display few calendar fields on the same page with different days disabled. I guess that the easiest way to do that would be to let thenoWeekendsOrHolidaysfunction take care of it but in order to do that I need to pass some values to it. How can I do that?
This example is much simplified as the original script.VBScript is making a value, passes this to Javascript, which puts that value into a div tag.Now, as you see in the VBScript, the value contains a call to a javascript function. It shows perfectly in HTML, but the call can't be made when clicking the link.Is it possible in VBscript to write dynamic hardcoded javascipt function that pass arguments?
I'm trying to create links that onclick sort a table by title, author, etc. How would I pass an argument to an event handler? Right now, it just executes the sort function. It doesn't wait for me to click the link.
Hw do I send arguments to an onreadystatefunction when calling a document via xmlhttprequest object. For example,
I want to do something like
function getDoc(url) xmlhttp=new XMLHttpRequest(); xmlhttp.onreadystatechange=writeHTML(id); xmlhttp.open("GET",url,true); xmlhttp.send(null); }
function writeHTML(id){ if (xmlhttp.readyState==4) { // if "OK" if (xmlhttp.status==200) { document.getElementById(id).innerHTML = xmlhttp.responseText; } }
Im trying to write a code to draw random numbers, like a lottery generator. It will require the user to input amount of numbers per line & choose the amount of numbers. From the numbers the user inputs it will generate random numbers to that guideline.
I have wrote the random number function, that works fine. Im having problems invoking it with ONCLICK event handlers. I cant seem to get the correct arguments. And all i get in return is "undefined"
This is the form for the onclick button <INPUT TYPE = "button" NAME = "drawBalls" VALUE ="Draw the Balls!" ONCLICK = "lotteryForm.drawnNumbersTextBox.value = ">
Now Im not putting up to much code, as its part of an Assignment, I dont want to cheat, i just want to be pointed in the right direction. :(
edited: the first alert has this in the brackets: &l t; i.e. the html code for < but for some reason this foum converts it. and i thought html was off?
I was expecting the above to alert the text in the brackets exactly as written in the code for both divs. However both events alert '<'. Why is that? I want to be able to pass '<' as an agrument to events without being converted, because that is what is happening. How may I prevent it?
I'm scripting Adobe InDesign via JS. (don't be frightened this post is purely about JS problem)
I've created custom 'Classes' for custom InDesign objects.They all inherit common methods from generic 'Item' class. Now the problem is that most of these methods need acces to the arguments of the child's constructor.
I'm seeing surprising behavior, consistent across Opera, Firefox, and IE. An event handler is changing the value of an element, and there is apparently no Change event being generated for the element. A simple illustration is, make an INPUT element with an onchange; type in a new value, the Change event handler is called. But make a button whose Click handler changes the value, and the Change handler does not get called.
It appears that events are not generated while an event handler is running. Can this be true?
When you click the main button, will one of the six images get a background image, and you can then press the image with the background image, and get your "reflextime".
But it won't work. When I press the image, were the new background image has shown, you can click on it and get your time - why?'
I try to add a function to be triggered also within an event (which already has a function). I coded it, unfortunatelly one line of the code should be different for IE and Moz. I try to find a common way without using a browser detector... Any ideea? The red line works for Mozilla, the blue one for IE:
function addFunc(){ var e = document.getElementsByTagName('*'); for(var i=0;i<e.length;i++){ if(e[i].getAttribute('onclick')||e[i].getAttribute('onclick')!=null){// Moz || IE //var f = new Function(e[i].getAttribute('onclick')); var f = e[i].getAttribute('onclick'); e[i].onclick=function(){f();otherFunction()} }}} Code:
I have no problem attaching an event handler to a single anchor labelled with an id. But I can't get the following to work on all anchors, meaning nothing happens. Any idea about what's wrong here? Code:
Im using onKeyUp on a text input field and everytime some information is gathered from a database through ajax.
Is there anyway to cancel onKeyUp events that are within X seconds of the previous event trigger? I dont want to use setTimeout because i dont want them called at all.
I modified a particular page in the following way:
I ran an init function on window.onload, which iterated thorugh the checkboxes on the page and assigned an event handler function - let's call it validate() to each checkbox.
I tested it in the big 5 browsers and ran into a strange issue in I.E. only -
let's say there are the following checkboxes code...
When I click on "box1" the function is not called. When check "box2" the function is called but by "box1", when I click on "box3" the function is called by "box2" and so forth...
I'm trying to dynamically create an image map for a particular image on my website, and I'm running into an issue where I try to register the "mouseover" and "mouseout" events for the AREAs of my image map.
I want to change the event handler for a form field, using JS code. But there doesn't seem to be a way to reference it. MyForm.SomeField.onChange is undefined. Anyone know if there's a way to do this?
I've many div with sequence of ids like d1 d2 d3 ... and I need to listen to their click event so I'm using a loop to add an event handler to them, Here it's my code:
for(var i = 0; i < $ds.length; i++){ var $d = $ds[i]; var xFunc = function(e){ document.title = "d: "+$d;
[Code]....
But when I click on each of them always the title goes to "d: 4" where 4 is the last value in $ds.
I'm creating a drop down menu so that when a user clicks on the drop down arrow and then hovers over one of the options, a bubble comes up and does a validation. The thing is that everything works fine in Firefox, but not in IE or Chrome. The problem is that the .mouseover() function doesn't work on the <option> tags in IE and Chrome, but it works fine in Firefox because apparently FF is the only browser that supports it.
