问题 After looking here I came up with a patter to test an array of words against a string. $.each(data, function(index, val) { var pattern = new RegExp('?:^|\s'+ val + '?=\s|$', 'g'); console.log(pattern.test(comment)); if (!pattern.test(comment)) { yay = true; } }); the problem here is that it returns true all the time. Any suggestions? Thanks! 回答1: From your JsFiddle, I forked and created one of my own, and your solution (with my regular expression from the comments) works quite well, once all

问题 Why does JavaScript throw a reference error if we try use a variable which is not declared but allows to set the value for the same ? e.g a = 10; //creates global variable a and sets value to 10 even though its undeclared alert(b); // throws reference error. so why for b, its reference error and not for the a? 回答1: That's just how the language works. In non-strict mode, an assignment to an undeclared symbol is implicitly treated as creating a global variable. In strict mode, that's an error.

问题 I am trying to retrieve a quote and its author from a JSON file, the problem I am having is that once I click the button once, then the event is fired but only once and no more after that. Equally, when I call $(document).ready() the button doesn't fire at all. I know that it is something to do with the way I am collecting the data from the JSON file (is an array of objects with text, author keys), and then subsequently calling the fetch when I want to retrieve a new quote with the correct

问题 Basically I want to use transformY but the subpixel blur is very annoying and only occurs when the div is an odd height. As the height depends on the text viewport etc, need this to be flexible so realistically need it to get the height of the div - Divide it by 2, round to the nearest number then x 2 so it'd always produce an even value. 回答1: The question is old, but it's the first answer on google for "rounding div height to even number", so it might help others. You have perfectly

问题 I made a carousel with reference of this link and originally posted on this link but unfortunately, I want no padding in first image. So I removed padding of first image but that create big width of image.

Is there a solution for adding gap between images (not in first and last image)? Codepen Link: https:

问题 I am currently working on a game in PHP and jQuery and at some point I will need to use the .load() from jQuery to load a PHP page into a div. That page will load some player information based on their login information, account id, etcetera, stored into an array inside $_SESSION["arrayname"] .

问题 Here's what I have now: code this is the html <div id="box"> <div id="line1" class="line"></div> <div id="line2" class="line"></div> <div id="line3" class="line"></div> </div> I would like to use jQuery to rotate line1 and line3 to form an X and make line2 disappear when you click the container div (#box).
