<div class="container">
<label ng-repaet"x in items">{{x}}</label>
</div>
我希望容器div的滚动条在容器溢出时自动进入底部,并将标签项添加到其中。
div容器的css类是:
.container{
position:relative;
display:block;
overflow-y:scroll;
overflow-wrap:break-word;
height:300px;
}
而且我的滚动条样式如下:
::-webkit-scrollbar{
width:6px;
}
::-webkit-scrollbar-track{
-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3);
border-radius: 0px;
}
::-webkit-scrollbar-thumb{
border-radius: 0px;
-webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5);
}
答案 0 :(得分:0)
您可以在指令的链接功能中添加$scope.$watch
,如下所示:
function dynamicContainer() {
return {
restrict: 'AE',
template: '<div class="container container-dynamic"><div ng-repeat="item in data track by $index">{{item}}</div></div>',
scope: {
data: '=data'
},
replace: true,
link: ($scope, $el, $attrs) => {
$scope.$watch(() => {
return $el[0].childNodes.length;
}, (newValue, oldValue) => {
$el.animate({
scrollTop: $el[0].scrollHeight
});
if (newValue !== oldValue) {
$el.animate({
scrollTop: $el[0].scrollHeight
});
}
});
}
};
}
此处为您pen。
