问题
I'm not sure why Microsoft hasn't allowed an Intellisense-friendly environment for using native regex with JavaScript in WebMatrix, but here is what I see when I attempt an otherwise normal JavaScript function:
As you can see, while this is perfectly valid JavaScript (using native regex), WebMatrix's Intellisense for my .js file is showing more random colors than a kaleidoscope.
I probably shouldn't be complaining, since it works, but I would like to restore human-readability if I can. I have noticed that this hasn't been mentioned anywhere else before (that I can find), and I was wondering if there were a more aesthetically pleasing way to handle this, given the environment.
I've tried using something like new RegEx(/&/g) for the first argument in the replace function, but of course, it produces the same glitch.
I've also tried storing the regex in a string, but I don't think that is in the format the first argument expects, so no dice there either.
I am not a master at regular expressions, by any means, so I apologize if I am overlooking a simple workaround here.
Is there anything I can do to retain this function in a more human-readable way?
--------------------------UPDATE-----------------------------
I just noticed that the line input = input.replace(/'/g, ",") is actually replacing an apostrophe with a comma. Rather than reload the picture, I will just mention that here (the proper hex code for apostrophe should be ').
回答1:
new RegExp(/&/g) does not really make sense as the /&/g already creates a RegExp object. You can use new RegExp('&', 'g') instead.
By the way, this is not the only problem there is with JavaScript Intellisense.
