Skinning effect: click on different pictures and change the background of the corresponding page

Realization idea

1. Define a group of pictures. Each src attribute assigns the background image path.

2. Get a set of picture element objects (get pseudo array)

3. The for loop binds the click event to the picture---onclick. In the event handler, set the background image of the body element object to---the path of the image currently clicked.

4. Note: the acquisition of the body element object is---document.body,js assigns a value to the path of the background image. Pay attention to the stitching of the path---document.body.style.backgroundImage = 'url (' + this.src +')'

Code sample skinning effect * {margin: 0; padding: 0; box-sizing: border-box;} body {background: url (images/ wallpaper 1.jpg) no-repeat center top; background-size: cover } .box {overflow: hidden; width: 610px; margin: 100px auto; background-color: # fff;} .box li {width: 25%; height: 100px; list-style: none; float: left; cursor: pointer Border: 1px solid # fff;} img {width: 100%; height: 100%;}

Var pics = document.querySelector ('.box'). QuerySelectorAll ('img'); console.log (pics); for (var I = 0; I < pics.length; iTunes +) {pics [I] .onclick = function () {console.log (this.src); document.body.style.backgroundImage =' url ('+ this.src +')' }} Page effect
