Javascript Manual Animation So let's implement one simple animation using DOM object properties and JavaScript functions as follows. The following list contains different DOM methods. We are using the JavaScript function getElementById() to get a DOM object and then assigning it to a global variable imgObj. We have defined an initialization function init() to initialize imgObj where we have set its position and left attributes. We are calling initialization function at the time of window load. Finally, we are calling moveRight() function to increase the left distance by 10 pixels. You could also set it to a negative value to move it to the left side. Example Try the following example. JavaScript Animation 358
Javascript Click button below to move the image to right Output It is not possible to show animation in this <strong>tutorial</strong>. But you can Try it here. Automated Animation In the above example, we saw how an image moves to right with every click. We can automate this process by using the JavaScript function setTimeout() as follows. Here we have added more methods. So let's see what is new here: The moveRight() function is calling setTimeout() function to set the position of imgObj. We have added a new function stop() to clear the timer set by setTimeout() function and to set the object at its initial position. Example Try the following example code. JavaScript Animation
