如何显示<a> tag from JavaScript in HTML by escaping characters

Question

I have a variable in my JavaScript, where I need to pass an anchor tag and a URL to route. But I am getting errors in my JS file and it looks like I need to escape my HTML tags, but it didn't work.

Can some one help?

var link = "<a href="http://localhost:3002/#/login?customerid=" >Continue</a>;

I tried below but it didn't work:

<a href="http://localhost:3002/#/login?customerid=" >Continue</a>

Answer 1

var link = '<a href="http://localhost:3002/#/login?customerid=" >Continue</a>';

错误是因为如果你打开一个字符串，“你必须用它来结束”，但你的href里面的url引用了“”，所以它显然无法使你的字符串变量。我刚刚引用了你的字符串'并且为了href。

Answer 2

您需要将该行重写为

var link = "<a href=\"http://localhost:3002/#/login?customerid=\" >Continue</a>";

原因是因为Javascript认为字符串在第一个"结束。为了防止这种情况，向后斜杠特别描述了它作为字符串

的一部分

但是，你首先使用它是什么？不建议在字符串中存储HTML。
