如何在 vue.js 2 上循环模板标签?
How to loop in template tag on the vue.js 2?
我的代码是这样的:
<template>
<nav aria-label="Page navigation">
<ul class="pagination">
<li>
<a href="#" aria-label="Previous">
<span aria-hidden="true">«</span>
</a>
</li>
@for(i=0;i<total;i++)
<li><a href="#">{{i}}</a></li>
@endfor
<li>
<a href="#" aria-label="Next">
<span aria-hidden="true">»</span>
</a>
</li>
</ul>
</nav>
</template>
<script>
export default{
props:['total', 'data'],
created: function(){
console.log(this.$store.state.product.next_page);
},
computed:{
next:function(){
return this.$store.state.product.next_page
}
}
}
</script>
我试试代码。但它不起作用。
存在错误:
[Vue warn]: Property or method "i" is not defined on the instance but
referenced during render. Make sure to declare reactive data
properties in the data option.
例如变量total = 5,则显示为:
<li><a href="#">1</a></li>
<li><a href="#">2</a></li>
<li><a href="#">3</a></li>
<li><a href="#">4</a></li>
<li><a href="#">5</a></li>
我该怎么做?
<li v-for="i in total">
<a href="#">{{i}}</a>
</li>
只需确保 total
是整数而不是字符串。例如,而不是
<component-name total="5"...
使用
<component-name :total="5" ...
