JavaScript/jQuery: replace part of string?
提问by matt
With text like this:
像这样的文字：
<div class="element">
<span>N/A, Category</span>
</div>
I want to get rid of every occurrence of N/A.
我想摆脱N/A.
Here is my attempt:
这是我的尝试：
$('.element span').each(function() {
console.log($(this).text());
$(this).text().replace('N/A, ', '');
});
The logged text is the text inside of the span so the selector is okay.
记录的文本是跨度内的文本，因此选择器没问题。
What am I doing wrong here?
我在这里做错了什么？

You need to set the text after the replace call:
您需要在替换调用后设置文本：
$('.element span').each(function() {
console.log($(this).text());
var text = $(this).text().replace('N/A, ', '');
$(this).text(text);
});<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="element">
<span>N/A, Category</span>
</div>Here's another cool way you can do it (hat tip @Felix King):
这是您可以做到的另一种很酷的方法（帽子提示@Felix King）：
$(".element span").text(function(index, text) {
return text.replace("N/A, ", "");
});

It should be like this
应该是这样的
$(this).text($(this).text().replace('N/A, ', ''))
