I would like to create a condition that checks the attribute for a particular value and the source of an image. If both values both match true, then do something.
我想创建一个条件来检查特定值的属性和图像的来源。如果两个值都匹配为true,则执行某些操作。
So far I have:
到目前为止我有:
if ($('meta[content="New Reviews"]').length > 0) && ($( "img[src*='default-label']" ) {
//Do something
}
Not sure if this is written correctly but I believe I wrote the syntax wrong.
不确定这是否写得正确,但我相信我写的语法错了。

You should make sure your parentheses match, and that you check length
for both collections:
您应该确保您的括号匹配,并检查两个集合的长度:
if ($('meta[content="New Reviews"]').length && $('img[src*="default-label"]').length) {
console.log('Found!')
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<meta content="New Reviews" />
<img src="default-label/image.png" />
