Challenge of html symbol to entity algorithm

Author：Eve Cole Update Time：2025-04-25 21:32:01

challenge:

Convert the characters &, <,>, (double quotes), and ' (single quotes) in the string to their corresponding HTML entities.

If you are stuck, remember to use the ultimate Read-Search-Ask. Try to communicate programming ideas with others, but write your own code.

For example:

convert(Dolce & Gabbana) should return Dolce & Gabbana.
convert(Hamburgers < Pizza < Tacos) should return Hamburgers < Pizza < Tacos.
convert(Sixty > twelve) should return Sixty > twelve.
convert('Stuff in quotation marks') should return Stuff in &quotation marks&quotation.
convert(Shindler's List) should return Shindler's List.
convert(<>) should return <>.
convert(abc) should return abc.

Answer:

method	describe
RegExp	It is the abbreviation of regular expressions.

replace()	Replace substrings that match the regular expression.

HTML character entity	Reserved characters in HTML must be replaced with character entities.

 function convert(str) { var list={ &:&amp;, <:&lt;, >:&gt;, '':&quot;, ':&apos;, }; for(var key in list){ str=str.replace(new RegExp(key,g),list[key]); } return str;}convert(Dolce & Gabbana);

Running results:

Dolce & Gabbana
