trim protractor

Today, I made a long mistake at the company. It may be due to my carelessness. Segment firstCode: String id = Params. Get ("ID") + ""; If (null = ID | "". Equals (Id. Trim ())){ // When ID is null .................. } Else { ................... } Let's see what is wrong with this code. I couldn't think of it for a long time. However, when ID is null, it always enters the else block. Where is the error of IF (null = ID | "". Equals (Id

When it comes to converting or editing image files in Linux, ImageMagick is undoubtedly one of the most well-known integrated software. It contains a complete set of command-line tools to display, convert, or copy raster or vector image files of more than 200 types, all at the command line. ImageMagick can be used for a variety of image editing tasks, such as converting file formats, adding special effects, adding text, and changing images (resizing, rotating, flipping, cropping).If you want to

The example in this article describes how PHP uses the Trim function to remove the left and right spaces and special characters of a string. Share to everyone for your reference, specific as follows: the trim () function in PHP is defined as follows : Trim (string,charlist) The parameter description is as follows: String required. Specify the string to check.

The trim () function solves this problemAs a subset of the trim () function, the LTrim () function is the special character that handles the left sid

The shell implements the trim function effect to remove spaces on both sides of the string, and the following three commands are equivalent, all of which can be implementedSed ' s/^\s*//' totrim.txt |sed ' s/\s*$//' >trimed.txtSed ' s/^\s*//;s/\s*$//' totrim.txt>trimed.txtSed-e ' s/^\s*//'-e ' s/\s*$//' totrim.txt>trimed.txtThe main thing is to use regular expressions, ^\s* represents 0 or more spaces in front of a string, and \s*$ represents 0 or mor

(1) Flat arrayThis is a well-known internet company today's front-end written questions: multidimensional array dimension variable, such as [2,4,1,[2,3,4,[1,2],5,3],3,8] beat flat for [2,4,1,2,3,4,1,2,5,3,3,8]. The number of dimensions is variable and should be recursive:Answer:function flatten(arr){var arrLength=arr.length;fori=0;ii++){ if(arr[i].constructor==Array){ arr.splice(i,1,flatten(arr[i])); }}return arr;}(2) Extract the parameters from the URL into an objectThis is also an

As shown below: function Bt_submit () { var $title = $.trim ($ ("#title"). Val ()); if ($title = = ") { showmessage (" operator name cannot be empty "," #ff0000 "); return; } Document.all.form1.submit (); } The HTML code is as follows: The above use of jquery in the trim () method to remove before and after the space is small to share all the content of everyone, hope to give you

But if the project does not use the framework such as jquery, JS itself does not have such a function, we have to write their own functions, the following is the specific implementation of the function: Copy Code code as follows: For consumer calls function Trim (s) { Return TrimRight (Trimleft (s)); } Remove the left blank function Trimleft (s) { if (s = = null) { Return ""; } var whitespace = new String ("\t\n\r");

----------------------------------JS to Space----------------------------------Remove the space between the left and right sides of the string, you can easily use trim, LTrim, or RTrim in VBScript, but in JS there are no 3 built-in methods that need to be written manually. The following implementation method uses regular expressions and is efficient and adds these three methods to the built-in methods of the string object.　　The methods written in the

$.trim (str) Back: string; Description: Remove the string and end space. Example: First look at the error code error code: Copy Code code as follows: var content = $ (' #content '). Val (); if (content.trim () = = ") Alert (' empty '); The above writing in Firefox will not be an error, but under IE will be an error So write the following format: Copy Code code as follows: var content = $ (' #results '). Val (

Copy Code code as follows: String.prototype.trim=function () { var _argument = Arguments[0] | | ""; var _re= new RegExp ("(^" +_argument+ "*) | ("+_argument+ "*$", "G"); Case sensitive Return This.replace (_re, ""); } String.prototype.ltrim=function () { var _argument = Arguments[0] | | ""; var _re= new RegExp ("(^" +_argument+ "*)", "G"); Return This.replace (_re, ""); } String.prototype.rtrim=function () { var _argument = Arguments[0] | | ""; var _re= new RegEx

The method written as a class is as follows: (Str.trim ();) We use regular expressions to manipulate The code is as follows Copy Code or write that. The code is as follows Copy Code function Trim (str) {for (var i = 0; Ifor (var j =str.length; J>0 Str.charat (j-1) = = ""; j--);if (i>j) return "";Return str.substring (I,J);} This can be written as a function: (
