我有问题!我不明白如何创建条件-在模板中-如果数组具有键为“ HIS”且长度超过一个的项,则不需要打印项。换句话说,如果该阵列仅包含NIS(不含其他货币),则不应显示... 我认为它应该像对象的 hasOwnProperty 一样工作,对吧?
var currencies = {
"NIS": {
"income": 12,
"received" : 13
},
"USD" : {
"income": 122,
"received" : 113,
"nisCourse" : 3,4
}
};
并认为它是ng-reapet
<div class="income_total_row"
ng-repeat-start="(key, value) in currencies track by $index"
ng-if="value.income != 0">
{{ value.income }}
</div>
<div class="income_total_row" ng-if="key !== 'NIS' && value.income != 0"
ng-repeat-end="">
{{ value.nisCourse }}
</div>
