trim

Play will assign the parameters from request to action parameters, like: public static void createArticle(String title, String content) { } But it won't trim them, so we usually to such code in the actions: public static void createArticle(String title, String content) { if(title!=null) title = title.trim(); if(content!=null) content = content.trim(); } Is there any way to let play trim them automatically? There are multiple ways to achive this with custom binders. One way of doing would be this: Define acustom binder somewhere that trims the string Annotate every parameter you want to trim

I need to split a keyword string and turn it into a comma delimited string. However, I need to get rid of extra spaces and any commas that the user has already input. var keywordString = "ford tempo, with,,, sunroof"; Output to this string: ford,tempo,with,sunroof, I need the trailing comma and no spaces in the final output. Not sure if I should go Regex or a string splitting function. Anyone do something like this already? I need to use javascript (or JQ). EDIT (working solution): var keywordString = ", ,, ford, tempo, with,,, sunroof,, ,"; //remove all commas; remove preceeding and trailing

I am trying to have a number string with maximum 2 decimals precision, while rest decimals just trimmed off instead of rounding them up. For example: I have: 123456.9964 I want: 123456.99 -> Just want to trim rest of the decimal places What I have tried is: NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; [numberFormatter setNumberStyle: NSNumberFormatterDecimalStyle]; [numberFormatter setMaximumFractionDigits:2]; NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat: 123456.9964]]; NSLog(@"%@", numberAsString); There is nothing to set

Hey, i try to trim each string item of an list in groovy list.each() { it = it.trim(); } But this only works within the closure, in the list the strings are still " foo", "bar " and " groovy ". How can i achieve that? list = list.collect { it.trim() } You could also use the spread operator: def list = [" foo", "bar ", " groovy "] list = list*.trim() assert "foo" == list[0] assert "bar" == list[1] assert "groovy" == list[2] According to the Groovy Quick Start , using collect will collect the values returned from the closure. Here's a little example using the Groovy Shell: groovy:000> ["a ", " b

I have a voice memo component in my app, and I want to allow the user to trim the audio, similar to QuickTime X on Mac OS Ten point Six handles it, or like the Voice Memos app on the iPhone. Here's an example of both: Any help is appreciated. I am not a UI programmer by any means. This was a test I wrote to see how to write custom controls. This code may or may not work. I have not touched it in some time. header @interface SUIMaxSlider : UIControl { @private float_t minimumValue; float_t maximumValue; float_t value; CGPoint trackPoint; } @property (nonatomic, assign) float_t minimumValue,
