trim

jQuery trim not working. I wrote the following command to remove white space. Whats wrong in it? var str = $('input').val(); str = jquery.trim(str); console.log(str); Fiddle example. jQuery.trim() capital Q? or $.trim() No need for jQuery JavaScript does have a native .trim() method . var name = " John Smith "; name = name.trim(); console.log(name); // "John Smith" Example Here String.prototype.trim() The trim() method removes whitespace from both ends of a string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator

Using Sox, how do I shorten an audio file by 5 seconds, trimming from the end? For example, this is how to trim a file from the beginning: sox input output trim 5000 This is how to add 5 seconds of silence to the end: sox input output pad 0 5000 yonix The syntax is sox input output trim <start> <duration> e.g. sox input.wav output.wav trim 0 00:35 will output the first 35 seconds into output.wav . (you can know what the length is using sox input -n stat ) From the SoX documentation on the trim command: Cuts portions out of the audio. Any number of positions may be given; audio is not sent to

I want to split this line: string line = "First Name ; string ; firstName"; into an array of their trimmed versions: "First Name" "string" "firstName" How can I do this all on one line? The following gives me an error "cannot convert type void": List<string> parts = line.Split(';').ToList().ForEach(p => p.Trim()); Try List<string> parts = line.Split(';').Select(p => p.Trim()).ToList(); FYI, the Foreach method takes an Action (takes T and returns void) for parameter, and your lambda return a string as string.Trim return a string Foreach extension method is meant to modify the state of objects

For example, I would like to create an array from the elements in this string: $str = 'red, green, blue ,orange'; I know you can explode and loop through them and trim: $arr = explode(',', $str); foreach ($arr as $value) { $new_arr[] = trim($value); } But I feel like there's a one line approach that can handle this. Any ideas? You can do the following using array_map : $new_arr = array_map('trim', explode(',', $str)); An Improved answer preg_split ('/(\s*,*\s*)*,+(\s*,*\s*)*/', 'red, green thing ,, ,, blue ,orange'); Result: Array ( [0] => red [1] => green thing [2] => blue [3] => orange )

I am using TrimEnd to remove certain characters from the end of a string. Initially I thought this would work: Dim strNew As String = "Employees\Sickness Entitlement.rpt" Dim strTrim As String = "Sickness Entitlement.rpt" Console.WriteLine(strNew.TrimEnd(strTrim)) '<- Doesn't work But TrimEnd only works for an array of chars or a single char string, so I tried this: Dim strNew As String = "Employees\Sickness Entitlement.rpt" Dim strTrim As String = "Sickness Entitlement.rpt" Dim arrChars As Char() ReDim arrChars(strTrim.Length) For i As Integer = 0 To strTrim.Length - 1 arrChars(i) = strTrim

If I have a dataframe structure like that: AA1_123.zip BB2_456.txt CCC_789.doc How can I change it to this: AA1 BB2 CCC If the strings are all the same style at the start, three characters before the underline, this will work: df1 <- structure(list(Col = c("AA1_123.zip", "BB2_456.txt", "CCC_789.doc" )), .Names = "Col", class = "data.frame", row.names = c(NA, -3L)) > substr(df1$Col, 1, 3) [1] "AA1" "BB2" "CCC" You could try sub sub('_.*', '', df1$Col) #[1] "AA1" "BB2" "CCC" data df1 <- structure(list(Col = c("AA1_123.zip", "BB2_456.txt", "CCC_789.doc" )), .Names = "Col", class = "data.frame",

I'd like to trim the leading whitespace inside p tags in XML, so this: <p> Hey, <em>italics</em> and <em>italics</em>!</p> Becomes this: <p>Hey, <em>italics</em> and <em>italics</em>!</p> (Trimming trailing whitespace won't hurt, but it's not mandatory.) Now, I know normalize-whitespace() is supposed to do this, but if I try to apply it to the text nodes.. <xsl:template match="text()"> <xsl:text>[</xsl:text> <xsl:value-of select="normalize-space(.)"/> <xsl:text>]</xsl:text> </xsl:template> ...it's applied to each text node (in brackets) individually and sucks them dry: [Hey,]<em>[italics]</em>
