javascript change background color on click

Question

Can you show me Javascript that allows you to change the background color of the page to another color  For example  I have a blue background color and I want to change it to green  The color must be changed when the user presses a button that triggers the event  I saw that it exists on many sites but I could not write the code I write in REACTJS I would love to have your help Thanks

Here you can find solutions for both your problems.

document.body.style.height = '500px';
document.body.addEventListener('click', function(e){
    var self = this,
        old_bg = this.style.background;

    this.style.background = this.style.background=='green'? 'blue':'green';
    setTimeout(function(){
        self.style.background = old_bg;
    }, 1000);
})

You can sets the body s background colour using document body style backgroundColor    red   so this can be put into a function that s called when the user clicks  The next part can be done by using document getElementByID  divID   style backgroundColor    red   window setTimeout  yourFunction    10000   which calls yourFunction in 10 seconds to change the colour back

If you want change background color on button click  you should use JavaScript function and change a style in the HTML page   function chBackcolor color       document body style background   color      It is a function in JavaScript for change color  and you will be call this function in your event  for example     lt input type  button  onclick  chBackcolor  red     gt    I recommend to use jQuery for this    If you want it only for some seconds  you can use setTimeout function   window setTimeout  chBackColor    10000

You can set the background color of an object using CSS   You can also use JavaScript to attach click handlers to objects and they can change the style of an object using element style property    value    In the example below I ve attached it in the HTML to a button but the handler could equally have been added to the body element or defined entirely in JavaScript    x000D   x000D  body   x000D    background-color  blue  x000D    x000D   lt button onclick  document body style backgroundColor    green    gt Green lt  button gt  x000D   x000D   x000D
