Question

Ok, I admit it, I suck at Regular Expressions. I’m trying to get the value of attribute data-hover-id.

I have the following javascript code:

var editText = "<span class='hover-content' data-hover-id='2' >Some text</span>";

var hoverId = -1;

// Get HoverID if it exists
var regex = /span.*data-hover-id=["']?((?:.(?!["']?\s+(?:\S+)=|[>"']))+.)["']?/;
var result = regex.exec(editText);
if (result.length > 1) {
  hoverId = result[1];
}

The results of the above code is hoverId equals ‘2 (apostrophe 2).

I want the value 2 without the quote or apostrophe. What would the regular expression be in this case? Is there a better way to do this in Javascript?

Answer 1

You can make your regex much simpler like:

var re = /data-hover-id=["'](.+)["']/;
var result = re.exec(str)[1];

Edit: If you need to account for no quotes at all try this one:

/data-hover-id=['"]?([^\s>]+)['"]?/
