I am not sure why you would need to listen for it. You could use JAlert and assign a click handler to the ok button. Something like. Is there a way to capture the alert ok button click event?
Asked By: Aperture. Answered By: davidbuzatto. Again as you click the link and remain inside the link area the alert will be shown, which is placed inside the event handler.
See example by clicking the link below:. This is a more visible example of click method where I have created five colored div elements.
Each div has different color — red, green, yellow, blue and black. In front of these five div elements a larger div is given with white color. As you click any of the colored div element, the color of larger div will be changed to the one that you clicked.
So what is done in the script section of code? Each div is created with an ID for which the style is created in the style section. In style section, each colored divs are given a color. Then in jQuery section, I used click jQuery event of each div element. In the following example, an animation is created. As you can see in the code of above example, when you click on the button, the click event triggers a function animateex that calls div element with the animate method and it starts animating with new CSS properties.
Once the animation is completed, the animate method calls a callback function animateex that will take animation back to what it was initially. The process goes on that was basically started after you clicked the button. Also, note that this is color animation, so I have also included jQuery UI library. You need to include the '. As per your code you have used for call click event function But is use for ID and dot.

Jquery click alert Ask Question. Asked 9 years ago. Active 9 years ago. Viewed 20k times. Do you know why this method click doesn't show alert? Because I'm not able to catch this event. Basically registering an event in modern way is the unobtrusive way of handling events. Also to register more than one event listener for the target you can call addEventListener for the same target.
Why use addEventListener? From MDN. Its benefits are as follows:. Other methods such as setting the HTML attributes , example:. Or DOM element properties , example:. HTML attribute should be avoided as It makes the markup bigger and less readable. The problem with the DOM element properties method is that only one event handler can be bound to an element per event. For better performance, use the native JavaScript. For faster development, use jQuery. Check the comparison in performance at jQuery vs Native Element Performance.
From what I understand, your question is not really about whether to use jQuery or not. Inline binding is deprecated. Moreover this way you can only bind one function to a certain event. Therefore I recommend using event listeners. This way, you'll be able to bind many functions to a single event and to unbind them later if needed. Consider this pure JavaScript code:. However, if you already include jQuery in your project — just use jQuery:.
As the second method is simple JavaScript code and is faster than jQuery. But here performance will be approximately the same. One must try to keep the page behaviour and structure different. This helps a lot. Difference in works. If you use click , you can add several functions, but if you use an attribute, only one function will be executed - the last one. If we are talking about performance, in any case directly using is always faster, but using of an attribute, you will be able to assign only one function.
I formed this opinion because of the fact that the JavaScript engines on mobile devices are 4 to 7 times slower than their desktop counterparts which were made in the same generation. I hate it when I visit a site on my mobile device and receive jittery scrolling because the jQuery is binding all of the events at the expense of my user experience and battery life.
Another recent supporting factor, although this should only be a concern with government agencies ; , we had IE7 pop-up with a message box stating that JavaScript process is taking to long This happened every time there were a lot of elements to bind to via jQuery. Seperation of concerns is key here, and so the event binding is the generally accepted method. This is basically what a lot of the existing answers have said. However don't throw away the idea of declarative markup too quickly.
It has it's place, and with frameworks like Angularjs, is the centerpiece. So it reached the point of sacrilegious proportions, much like tables. Some developers actually avoid tables for tabular data. It's the perfect example of people acting without understanding.
Although I like the idea of keeping my behaviour seperate from my views. I see no issue with the markup declaring what it does not how it does it, that's behaviour. It might be in the form of an actual onClick attribute, or a custom attribute, much like bootstraps javascript components. This way, by glancing just at the markup, you can see what is does, instead of trying to reverse lookup javascript event binders.
So, as a third alternative to the above, using data attributes to declarativly announce the behaviour within the markup.
