我有一个数组slides，其中包含变量stars。我需要在每张幻灯片上获取stars的值，然后使用该数字为每张幻灯片重复HTML字符串。
我可以得到stars的值，但是它会遍历所有6张幻灯片，并提供其值6次。
我只需要获取stars的所有值一次。
var slides = [
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 4
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 3
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 2
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 1
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 5
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 2
}
];
$scope.addStars = function(){
i = 1;
for (i=1; i<slides.length; i++) {
var starsCount = slides[i].stars;
var starsHTML = '<a href="#">☆</a>';
starsFinal = starsHTML.repeat(starsCount);
console.log(starsFinal);
}
}
最佳答案
您可以执行以下操作：
$scope.slides = [
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 4
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 3
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 2
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 1
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 5
},
{
'text' : 'The staff was fantastic and very friendly. I would definitely recommend them to anyone. The care has been great!! - ONLINE REVIEWER',
'stars' : 2
}
];
$scope.addStars = function(startCount) {
return Array(startCount).fill().map(function() {
return '<a href="#">☆</a>';
}).join('');
}
<div ng-repeat="slide in slides">
<div ng-bind-html="addStars(slide.stars)"></div>
</div>
