我的AngularJS网络应用程序实际上存在问题。
所以我认为这是:
<div class="xe-widget xe-counter" data-count=".num" data-from="0" data-to="{{ users }}" data-suffix=" / 30" data-duration="2">
<div class="xe-icon">
<i class="linecons-user"></i>
</div>
<div class="xe-label">
<strong class="num">0</strong>
<span>Joueurs en ligne</span>
</div>
</div>
在我的控制器中,我添加了这个:
$scope.users = 10;
但问题是数据到=&#34; {{用户}}&#34;在div中,似乎无法工作..当我尝试将数据替换为=&#34; {{users}}&#34;具有静态值,如:data-to = 10;它在工作。
我做错了吗?
这是计数器的指令
directive('xeCounter', function(){
return {
restrict: 'EAC',
link: function(scope, el, attrs)
{
var $el = angular.element(el),
sm = scrollMonitor.create(el);
sm.fullyEnterViewport(function()
{
var opts = {
useEasing: attrDefault($el, 'easing', true),
useGrouping: attrDefault($el, 'grouping', true),
separator: attrDefault($el, 'separator', ','),
decimal: attrDefault($el, 'decimal', '.'),
prefix: attrDefault($el, 'prefix', ''),
suffix: attrDefault($el, 'suffix', ''),
},
$count = attrDefault($el, 'count', 'this') == 'this' ? $el : $el.find($el.data('count')),
from = attrDefault($el, 'from', 0),
to = attrDefault($el, 'to', 100),
duration = attrDefault($el, 'duration', 2.5),
delay = attrDefault($el, 'delay', 0),
decimals = new String(to).match(/\.([0-9]+)/) ? new String(to).match(/\.([0-9]+)$/)[1].length : 0,
counter = new countUp($count.get(0), from, to, decimals, duration, opts);
setTimeout(function(){ counter.start(); }, delay * 1000);
//alert(to); --> Printing {{users}}
sm.destroy();
});
}
};
}).
我添加了警报(to);检查值是否已正确发送,但我得到了{{users}}而不是值..

您必须包含一个ng-controller来告诉angular在哪里查找范围变量。尝试在视图中添加ng-controller属性
<div ng-controller="YourController" class="xe-widget xe-counter" data-count=".num" data-from="0" data-to="{{ users }}" data-suffix=" / 30" data-duration="2">
<div class="xe-icon">
<i class="linecons-user"></i>
</div>
<div class="xe-label">
<strong class="num">0</strong>
<span>Joueurs en ligne</span>
</div>
</div>

我认为这对你来说太迟了,但对其他人来说可能有用。
替换你的指令:
directive('xeCounter', function () {
return {
restrict: 'EAC',
link: function (scope, el, attrs) {
var $el = angular.element(el),
sm = scrollMonitor.create(el);
sm.fullyEnterViewport(function () {
var opts = {
useEasing: attrDefault($el, 'easing', true),
useGrouping: attrDefault($el, 'grouping', true),
separator: attrDefault($el, 'separator', ','),
decimal: attrDefault($el, 'decimal', '.'),
prefix: attrDefault($el, 'prefix', ''),
suffix: attrDefault($el, 'suffix', '')
},
$count = attrDefault($el, 'count', 'this') == 'this' ? $el : $el.find($el.data('count')),
from = attrs.from ? attrs.from : 0,
to = attrs.to ? attrs.to : 100,
duration = attrs.duration ? attrs.duration : 2.5,
delay = attrs.delay ? attrs.delay : 0,
decimals = String(to).match(/\.([0-9]+)/) ? String(to).match(/\.([0-9]+)$/)[1].length : 0,
counter = new countUp($count.get(0), from, to, decimals, duration, opts);
setTimeout(function () {
counter.start();
}, delay * 1000);
sm.destroy();
});
}
};
}).
HTML应该保持这样:
<div class="xe-widget xe-counter" xe-counter data-count=".num" data-from="0" data-to="{{ total }}" data-suffix="" data-duration="5">
<div class="xe-icon"><i class="linecons-cup" /></div>
<div class="xe-label"><strong class="num">0</strong><span>TOTAL</span></div>
</div>
确定 $ scope.total 变量已声明且其值为数字。
