需求：现在有一堆列表，当我每次点击列表的每一项时，希望将此项添加到一个数组中，并且已添加的数据不能再添加

<script type="text/javascript" src="jquery-1.8.3.min.js"></script>
<script type="text/javascript">
$(function(){
var arr = []
$('span').click(function(){
var this_obj = {
title:$(this).text(),
url:$(this).attr('data-url')
}
console.log('当前选择的：',this_obj)
let indexTow = arr.findIndex((e) => {
return e.url == this_obj.url;
});
if (indexTow < 0) {
arr.push(this_obj);
}
console.log('新数组：',arr)
});
});
</script>
