有一个这样的网站:
有必要当你点击一个按钮时,这个按钮的颜色变成淡紫色,而之前选择的按钮变成白色。
$(document).ready(function() {
all__buttons=document.querySelectorAll('.header__button');
/*selected__button.click= function(){
selected__button.backgroundColor='#5f3ec0';
};*/
function changeColor(inputbutton) {
inputbutton.style.backgroundColor='#5f3ec0';
}
[].forEach.call(all__buttons, function(selected__button){
selected__button.addEventListener('click', changeColor);
});
}
)
body {
margin: 0;
padding: 0;
}
.globalcontainer {
margin-top: 0px;
margin-right: 15px;
margin-bottom: 0px;
margin-left: 15px;
}
.header > .header__text {
position: relative;
width: 93px;
height: 24px;
left: 0;
margin-top: 129px;
margin-bottom: 20px;
font-family: TT Norms;
font-style: normal;
font-weight: bold;
font-size: 24px;
line-height: 100%;
/* identical to box height, or 24px */
color: #000000;
}
/*
.header__buttons {
left: 0;
top: 193px;
}
*/
.header__button {
border-radius: 3px;
background-color: #fff;
}
