I am just curious how would anyone make this. I am trying to figure out with lack of knowledge and of course I cannot make it.
So it would be something like...
If in jquery there is declared onClick function something like "firstGateway" and "secondGateway" how can I add what if there is first and what if its second.
I can't even explain well.
But let me try.
<a onClick="firstGateway">YES FIRST!</a>
That would be html piece and jquery would need to run following:
<script type="text/javascript" src="http://fileice.net/gateway/mygate.php?id=492b542f45684b42"></script>
onClick=startGateway('123456');
and if it would be in html like this:
<a onClick="secondGateway">YES SECOND!</a>
Then jquery would run following:
<script type="text/javascript" src="http://fileice.net/gateway/mygate.php?id=4465766c4278366467523838"></script>
onClick=startGateway('654321');
Hope you understand me. I will still try to make it work but I do not think I will be able to succeed.
$('a').click(function(e){
if (e.target.innerHTML == "something")
//fooo
else
// Bar
});
You can check anything you want inside the callback. e.target is the anchor that was clicked.
if (e.target.id == "someId")
if ($(e.target).hasClass('fooClass'))
With your current code, if someone clicks on the link nothing happens. Let's fix that first of all:
This:
<a onClick="firstGateway">YES FIRST!</a>
Should be this:
<a onClick="firstGateway()">YES FIRST!</a>
If you want to execute the function firstGateway() whenever the user clicks that link. However, this is still not the best way and I'm going to show you a better way below. (Note that this better way is also needed for my final solution).
Now we turn this into:
<a id='gateway1'>YES FIRST!</a>
No longer do we define the event in the HTML, instead we do so in our javascript using jQuery:
$(document).ready(function ()
{
$('a#gateway1').click = firstGateway; // Do note: this time around there are
// no brackets
}
Using this, you can now do several things. First, you could do this:
$('a#gateway1').click();
It simulates a click on the link, which I believe does the thing you wanted to do.
However, in order to write your code, you have made sure that you knew what function you were connecting to it in your javascript, so you might not even need such a solution anymore as you should be able to do this:
$(document).ready(function ()
{
$('a#gateway1').click = firstGateway; // Do note: this time around there are
// no brackets
firstGateway();
}

I have GA on my website and i'm trying to track every click on the website. The following JavaScript must be used, it acts like an overlay on the page:
<script type="text/javascript">
var tile = new HTMLLiveTile.TileController();
window.onmousedown = function() {
tile.openStoreProduct("var1", "var2", "var3");
}
</script>
What would be the HTML equivalent code to track this?
Right now i have:
<a id="tile" onClick="ga('send', 'event', 'click1', 'click2', 'sample');"><img src="./images/image.png"> </a>
I'm very new to this, sorry if it's redundant. My assumption was to track the variable and add it to the onClick.
I guess you are asking for a solution that does not require much hassle and much changing in code and moreover without any need to change your previous code.
you can use event.target.+ things you need to know to get info.
function mouseTrack(){
var element_name = event.target.tagName;
alert("mouse click was detecteted at: "+ element_name);
}
window.addEventListener('click', mouseTrack(), false);
this code will alert the Tag Name of Element clicked (like DIV, a, SPAN etc you know the list.). But this code is awful.It wont work in Mozilla FF, It wont work In IE 9 below. I took some time to create a fiddle on JSFiddle.net you can view example I made Here
I downloaded the jQuery plugin letter-fx (http://tuxsudo.com/code/project/letterfx) and really like what it can do.
However, on my landing page I'm trying to make the different paragraphs appear in sequence. I thought the best way to do that is to delay each paragraph with setTimeout()
I'm a JS/jQuery novice and hoping someone can help me out. Here's the code I have thus far:
$(function(fx1){
$(".fx1").letterfx({"fx":"fade","backwards":false,"timing":50,"fx_duration":"1000ms","letter_end":"restore","element_end":"stay"});
});
$(function(){
setTimeout(fx1,3000);
});
Can anyone show me what I'm doing wrong? Thanks!
Try below code. To use setTimeout you need to pass a function as first param.
$(function(){
var applyAnimation = function(){
$(".fx1").letterfx({"fx":"fade","backwards":false,"timing":50,"fx_duration":"1000ms","letter_end":"restore","element_end":"stay"});
};
setTimeout(applyAnimation,3000);
});
I have a homepage that dynamically writes javascript in order to handle the mouseover of potential user choices. However, the .bind("mouseover",function()) does not seem to be working.
The PHP produces a script like this:
<script type="text/javascript">
function setPreview(art, title, rt, excerpt) {
$("#boxPreview").attr("src", art);
$("#selectedTitle").text(title);
$("#runningTime").text(rt);
$("#excerpt").text(excerpt);
}
$(document).ready(function() {
$("#tb0").bind("mouseover",setPreview(url,title,running time,excerpt));
$("#tb1").bind("mouseover",setPreview(url,title,running time,excerpt));
$("#tb2").bind("mouseover",setPreview(url,title,running time,excerpt));
$("#tb3").bind("mouseover",setPreview(url,title,running time,excerpt));
</script>
However, it seems that the mouseover event never fires. Instead, it seems that when the page is fully loaded, setPreview is run for the very last element (#tb3).
I have no idea what I'm doing wrong. If you would like to see the page in action for yourself, you can view it here.
You may try writing the same code like this
$("#tb0").bind("mouseover" , function(){
setPreview(url,title,running time,excerpt);
});
This may solve your issue. Because i've got same issue before but it was fixed writing this way.
Hello I'm writing a jQuery code for my application and got some issues (like function called once, running three times).
I must know if exist any site that people audit source code and comment my mistakes..
most of my code is like this i/e:
$('a.openBox').click(function(){
//do something
$('.box').show();
$('a.openModal','.box').click(function(){
$.openModal(some, parameters)
});
});
$.openModal = function(foo,bar){
//do something
$('a.close').click(function(){
$('#modal').hide();
});
$('input.text').click(function(){
$.anotherFunction();
});
});
does am I doing something obviously wrong?
I'm not aware of any source code audit like that -- certainly not for free! This website is pretty good for specific problems though...
In this case, the problem is that you are continually binding more and more events. For instance, with the following code:
$('a.openBox').click(function(){
//do something
$('.box').show();
$('a.openModal','.box').click(function(){
$.openModal(some, parameters)
});
});
This code says "whenever the user clicks on an a.openbox element, show all .box elements and bind a new click handler to all .box a.openModal elements". This means that you will add another handler to .box a.openModal every time you click on a.openbox. I can't believe this is what you want to do!
It is difficult to work out what the correct code should be without knowing the context and exactly what you want to happen. My advice for you in the first instance would be to do some reading up on Javascript events and event handlers, particularly as they are implemented in jQuery.
Which is preferable, assuming we don't care about people who don't have JavaScript enabled?
Or
Is there any difference?
Or there any other ways I'm missing besides attaching an event to the anchor element with a JavaScript library?
The nice thing about onclick is you can have the link gracefully handle browsers with javascript disabled.
For example, the photo link below will work whether or not javascript is enabled in the browser:
foobar
it's better to use the onclick because that's the way the things should be.
The javascript: was somekind of hackish way to simulate the onclick.
Also I advice you to do some non intrusive Javascript as much as possible, it make the code more easy to read and more maintainable!
href="#" has a number of bad side effects such as showing # in the browser footer as the destination URL, and if the user has javascript disabled it will add a # at the end of their URL when they click the link.
The best method IMHO is to attach the handler to the link in your code, and not in the HTML.
var e = document.getElementById("#myLink");
e.onclick = executeSomething;
This is essentially the pattern you'd want to follow:
Write your HTML markup
Attach event handlers from JavaScript
This is one way:
<a id="link1" href="#">Something</a>
<script type="text/javascript">
// get a reference to the A element
var link1 = document.getElementById("link1");
// attach event
link1.onclick = function(e) { return myHandler(e); };
// your handler
function myHandler(e) {
// do whatever
// prevent execution of the a href
return false;
}
</script>
Others have mentioned jQuery, which is much more robust and cross-browser compatible.
Best practice would be to completely separate your javascript from your mark up. Here's an example using jQuery.
<script type="text/javascript">
$(function() {
$('a#someLink').click( function() {
doSomething();
return false;
});
});
</script>
...
some text
Yes I would agree to use onclick and leave the href completely out of the anchor tag... Don't know which you prefer to do but I like to keep the 'return false' statement inside by function as well.
The main difference is that:
The browser assume by default the href attribute is a string (target url)
The browser knows that in a onclick attribute this is some javascript
That's why some guys specify to the browser "hey, interpret javascript when you read the href attribute for this hyperlink" by doing ...
To answer the question, that's the difference!
OTOH what's the best practice when using javascript events is another story, but most of the points have been made by others here!
Thanks
