“和”的区别

Question

I'm building an angular 2 application similar to typing test. There's a text and user needs to type that out. I am comparing every typed word with the corresponding word in the text.

The word “collection (with the inverted comma) can't be compared as it is never equals to "collection (with inverted comma) . Couldn't find anything on google and SO.

Here's a image reference from augury.

status 1 says that these two aren't equal.

Is there any way to make them equal or do i have to replace all these instances in the text with "

Answer 1

When comparing strings having characters that should be treated as equivalent they are typically "folded" together.

On one hand there are projects like fold-to-ascii , which I have not used, that fold quite a few similar characters.

On the other hand you can create a simple remapping yourself, say something like this, which splits the string into an array of characters, remaps each character found in the equivalence mapping and joins the result back into a string.

 var equivalenceMap = { '“': '"', '”': '"', ''': "'", ''': "'" }; function foldString(src) { return src.split('').map(function (c) { return (c in equivalenceMap) ? equivalenceMap[c] : c; }).join(''); } console.log('Strings equivalent: ' + (foldString('“collection') == foldString('"collection')));
