I'm in a sticky situation. I'm trying to make an image an upload button, but I cannot change that image at all... however, when you click the image, I have it calling a JS function I can put anything into.
How can I launch an browser upload though this function alone? Normally I would just make the image an input, but like I said, in this case I cannot do that.
Does anyone have an example they could share?
Here's my function (which is called onclick of the image):
function fnImport(elem){
var $input;
$input = $input || $("<input type='file'>");
$('#Import').append($input);
$input.click();
$input.hide();
}
However, when I run it, on the first click it adds the button, then on second it acts as an upload (and doesn't hide in either).
In addition, I'm getting a strange as well in my console?
Something like this might spark some ideas for you: http://jsfiddle.net/NKekN/2/

I have a simple javascript program that runs onclick of an image.
However, whenever I clicked the image, the page reloaded.
After a lot of debugging I found that the page doesn't reload until right as the script completes.
There are several setTimeouts in the code, but I noticed the page was reloading instantly. I even changed these timeouts to 15000 milliseconds, but it still reloads immediately.
I am using jquery, if it makes any difference.
I also want a different result from the program every time you click it, so that each time you click it a different script runs and a some text changes in a specific order. I did this by changing the onclick attribute of the images in each script to the name of the next script, so that script one would switch onclick to script two, and so on. I set a timeout on these switches so that one click doesn't race through every single script. script two isn't running, so that much works.
my code:
function getSounds() {
console.log("script. initiated");
$("#soundwebGetSoundDirections").html("Now, Wait until the file is done downloading and click below again.");
console.log("new message");
$("#soundwebGetSoundA").attr('href',"");
console.log("href eliminated");
setTimeout($("#soundwebGetSoundImg").attr('onclick','findFile()'),2000);
console.log("onclick to findFile()");
}
function findFile(){
console.log("FINDFILE")
$("#soundwebGetSoundDirections").html("Find the file(it's probably in your downloads), copy the path of the file (usually at the top of the file explorer) and paste in it the box below. Then, make sure there is a '/' at the end of the path and type 'Linkiness.txt' (case sensitive, without quotes) at the end. Once you have all that stuff typed, click the icon again.");
console.log("FIND IT, DARN IT!!");
$("#soundwebGetSoundPathInput").css("opacity",1);
console.log("diving into reader");
setTimeout($("#soundwebGetSoundImg").attr('onclick','readFile()'),1000);
}
function readFile(){
console.log("loading...");
$("#soundwebGetSoundDirections").html("loading...");
if(document.getElementById("soundwebGetSoundPathInput").value.length == 0){
setTimeout($("#soundwebGetSoundDirections").html("Please fill in Path!"),1000);
setTimeout(findFile(),2000);
}
}
and the HTML that's linked to,
<a id = "soundwebGetSoundA" href = "https://docs.google.com/feeds/download/documents/export/Export?id=1ynhHZihlL241FNZEar6ibzEdhHcWJ1qXKaxMUKM-DpE&exportFormat=txt">
<img onclick = "getSounds();" class = "soundwebImgResize" src = "https://cdn3.iconfinder.com/data/icons/glypho-music-and-sound/64/music-note-sound-circle-512.png" id = "soundwebGetSoundImg"/>
</a>
Thanks for any help,

If you don't want clicking the image to cause the anchor tag to load the href, then move the image tag outside of the anchor tag.
You aren't using setTimeout correctly. You should be passing in a function not a statement. So, for example, instead of
setTimeout($("#soundwebGetSoundDirections").html("Please fill in Path!"),1000);
setTimeout(findFile(),2000);
you should use
setTimeout(function () { $("#soundwebGetSoundDirections").html("Please fill in Path!") },1000);
setTimeout(findFile,2000);
I think the same goes for setting the onclick attribute but I've never tried dynamically changing an onclick attribute like that.
Since you're already using jQuery you could try using .on('click'... and .off('click'... if your current setup isn't working.
I am trying to solve a riddle here. Imagine the following. The user uploads one image, which a minute later he wants to replace. Thus he clicks on the image and selects the upload button again, chooses another image and uploads it. In the editor this image is shown, but when he saves the change, the old image is shown again.
My guess is, that this is due to the fact that only the src-attribute gets updated, but not the data-cke-saved-src-attribute. The question now is: How do I change that?
I should also mention, that since I have a blur-handler, that is asking the user if he wants to discard the change. This fires whenever an dialog opens, which is why I am "refocusing" the editor using the following snippet:
CKEDITOR.on('dialogDefinition', function (e) {
var dialog = e.data.definition.dialog;
dialog.on('hide', function () {
dis.ckEditor.focusManager.hasFocus = true;
$('.cke').show();
});
});
I am currently applying for an Internship Internship Link
One of the things that I noticed right away is that you click on upload cover letter or paste cover letter, you're redirected to the home page of the job invite site Job Invite and sadly you can't upload your cover letter. On the other hand, the upload resume works perfectly fine but paste resume has the same issue.
Does anyone know how to resolve this issue and and be able to submit a cover letter?
I am not a web guru but since I am applying for an engineering position, I am trying to find a way around this. I right clicked the upload cover letter link and inspected the link with the inspect element tool. I found that this function
onclick="jvAddAttachment2('jvcoverletter', 'qLY9Vfwx')
was going to get called when the button is clicked. Now going into the JavaScript file for this html page, Inspect Element -> Sources -> *careers_8.js?v=303, I tried to do a basic alert statement, from alert dialog, to do some debugging to see what the issue is. Here's the code now
function jvAddAttachment2(id, companyId){
alert("I got here");
....
}
I then did control s and the Inspect Element console outputted "Recompilation and update succeeded." so I am assuming the JavaScript file has been updated. However when I click the link(via right click, open new window), no alert box shows up. Does anyone know how to get the alert dialog to show up? I think I've done as much as I can with my working knowledge from one web development course haha.
You're looking for the contextmenu event for right click:
element.addEventListener('contextmenu', function() {
// code here
});
Please don't use inline js, like onclick in your html. The above sample is the proper way to attach event listeners.
You should get your element reference in javascript with var myElem = document.getElementById('the-id') or some similar function like document.querySelector, etc.
Then, you can easily attach both events like this:
// left click
myElem.addEventListener('click', myFn);
// right click
myElem.addEventListener('contextmenu', myFn);
If you're adamant to do this with inline js, that would be:
<div onclick="myFn()" oncontextmenu="myFn()"></div>
Full demo of both approaches for ya:
var myElem = document.getElementById('my-element');
myElem.addEventListener('click', myClickFn);
myElem.addEventListener('contextmenu', myClickFn);
function myClickFn() {
console.log('this is myClickFn!');
}
function someFn() {
console.log('this is someFn!');
}
<div id="my-element" onclick="someFn()" oncontextmenu="someFn()">Left or Right click me!</div>
Also, since you're wanting to pass parameters to the function you'll be calling on click, it is good to use an intermediary function for the event, and have that function call the other function, passing the parameters, like this:
function myClickFn() { // this is called on click
myOtherFunction('some', 'params');
}
That prevents you having to repeat the same function call, passing those same parameters in both places.
Make sure to close your onclick string at the end with a ":
onclick="jvAddAttachment2('jvcoverletter', 'qLY9Vfwx')"
And left click instead of right clicking.
onclick="jvAddAttachment2('jvcoverletter', 'qLY9Vfwx')"
I think that double quotation was absent.

I'm stuck modifying someone else's source code, and unfortunately it's very strongly NOT documented.
I'm trying to figure out which function is called when I press a button as part of an effort to trace the current bug to it's source, and I"m having no luck. From what I can tell, the function is dynamically added to the button after it's generated. As a result, there's no onlick="" for me to examine, and I can't find anything else in my debug panel that helps.
While I prefer Chrome, I'm more than willing to boot up in a different browser if I have to.
In Chrome, type the following in your URL bar after the page has been fully loaded (don't forget to change the button class):
var b = document.getElementsByClassName("ButtonClass"); alert(b[0].onclick);
or you can try (make the appropriate changes for the correct button id):
var b = document.getElementById("ButtonID"); alert(b.onclick);
This should alert the function name/code snippet in a message box.
After having the function name or the code snippet you just gotta perform a seach through the .js files for the snippet/function name.
Hope it helps!
Open page with your browser's JavaScript debugger open
Click "Break all" or equivalent
Click button you wish to investigate (may require some finesse if mouseovering page elements causes events to be fired. If timeouts or intervals occur in the page, they may get in the way, too.)
Inspect the buttons markup and look at its class / id. Use that class or id and search the JavaScript, it's quite likely that the previous developer has done something like
document.getElementById('someId').onclick = someFunction...;
or
document.getElementById('someId').addEventListener("click", doSomething, false);
You can add a trace variable to each function. Use console.log() to view the trace results.
Like so:
function blah(trace) {
console.log('blah called from: '+trace);
}
(to view the results, you have to open the developer console)
First of all, here is the site I am working on.
I am trying to get a modal window to pop-up when elements in the Flash are clicked on. Which at this point I have about 90% working when you click on the warrior image. Below is a list of issues I am still trying to solve that I hope you can help me with...
The modal background doesn't fill up
the whole page like it should.
I cannot get the close button to work
I need to set the vidname variable in
both the Flash and Java to load in a
dynamic HTML file. Depending on which
image is clicked on. My naming
convention will probably be something
like vid-1.html, vid-2.html, etc.
If you need to look at the .js file you can view it at /cmsjs/jquery.ha.js
Below is the ActionScript I currently have...
var vidname = "modal.html";
peeps.vid1.onRelease = function() {
getURL('javascript:loadVid(\'' + vidname + '\');');
};
Well I have one for you.
Your current close code is
$('#modalBG, #modalClose').click(function(){
closeModal();
});
If you click the background after a video loads you'll see that the modal does close. The reason your close button does not work is because #modalClose does not exist in the DOM when you are binding to the click function.
You need to either rebind the modalClose element when you modify the DOM or use live. If you use live you just need to change your click code to this:
$('#modalBG, #modalClose').live("click", (function(){
closeModal();
});
