javascript document.write 打印“<”

Question

我正在尝试在 javascript 中的 document.write 中打印此文本“<Place>” 。但我无法打印它。由于“<”符号，它没有打印。需要帮助。

Answer 1

document.write('<Place>');

You have to represent the special character < , using the HTML entity < . Otherwise, your string will be interpreted as a HTML tag.

Answer 2

I agree with @Paul Draper's answer as being a solution for this question.

However, you should be aware of characters that have special meaning in HTML and always convert special characters to character entities .

If you are not careful and simply include the characters, than the browser will try to interpret them. This could lead to potential issues and big headaches where unwanted HTML elements might get included down the line.

In this particular example it would be wise to encode both < and >

document.write('<Place>');
