D3.js ~ How to filter data values containing certain values/words?

Question

filtering data for a visualization I noticed that some values that do not correspond exactly to the values contained in the filter are not passed. what I would like to do is to filter all the values in my dataset that contain that word, now i have:

stile.filter(function (d) { return d.StyleName == "Bold" || d.StyleName == "Demi" || d.StyleName == "Semibold"; });

I thought that adding the .contains() at the end of each value I want filtered could do the trick, like so:

stile.filter(function (d) { return d.StyleName.contains("Black") || d.StyleName.contains("Heavy") || d.StyleName.contains("Extrabold") || d.StyleName.contains("BoldNonextended"); })

But this didn't work unfortunately. Any help as always is really appreciated, thanks!

EDIT: my dataset is a csv, the StyleName column has vairous values, like: Bold, Bold Extended, Regular and so on. If I use the filter function that I have now, the data row containing Bold Extendend for example, is not returned because it has the word Extended also in it. That's what I'm trying to solve

Can you post some example data and expected output with your question? — mdml

Instead of contains try using match() and regular expressions:

stile.filter(function (d) { return d.StyleName.match(/Black/) || d.StyleName.match(/Heavy/) || d.StyleName.match(/Extrabold/) || d.StyleName.match(/BoldNonextended/); })
