In the following example, we use this attribute to add three methods to the String object: Trim, LTrim, and RTrim (same as the function of the same name in VbScript) Copy codeThe Code is as follows: String. prototype. Trim = function () { Return this. replace (/(^ \ s *) | (\ s * $)/g ,""); } String. prototype. LTrim = function () { Return this. replace (/(^ \ s *)/g ,""); } String. prototype. Rtri

$.trim (str)Returns: string;Parameter str:string type, a string that needs to be stripped of both whitespace characters.

Original: Http://www.tuicool.com/articles/AzmaMjafter iOS7.0, the uilabel automatically removes all whitespace characters from the end of the text line, except for the usual half-width spaces (\0x20) and tabs (\ t), and the full-width spaces (\u3000) are also counted, and even extra line breaks (\r,\n) are automatically removed. Although it is convenient to directly assign the control and no value after the trim, but too intelligent, often can not mee

Understand eval () function in JS and write a function trim () to remove spaces between the left and right strings. Trim () is a reference to the jquery source code, you can rest assured to use. My understanding of eval () functions in JS is not necessarily correct.

However, if jQuery and other frameworks are not used in the project, js itself does not have such a function. We have to write such a function by ourselves. The specific implementation of the function is as follows:Copy codeThe Code is as follows:// For the user to callFunction trim (s ){Return trimRight (trimLeft (s ));}// Remove the left blankFunction trimLeft (s ){If (s = null ){Return "";}Var whitespace = new String ("\ t \ n \ r ");Var str = new

The two functions are understood because of the fact that they have encountered the problem of OJ:Callout input is: 4 ABCThe two types of data are separated by a space, but the method of reading only one character is not found (eats the middle space)Trim (): Remove whitespace from the end of the stringString str= "Hello World"; str=str.trim (); // after executing the statement, the value of STR is "Hello World"Str=str.substring (m);//intercept str fro

Given A binary search tree and the lowest and highest boundaries as L and R, trim the tree so it all it elements Li Es in [L, R] (R >= L). You might need to change the root of the tree, so the result should return the new root of the trimmed binary search tree. Example 1:Input:1 / \0 2L = 1R = 2Output:1 \2Example 2:Input:3 / \0 4 \2 /1L = 1R = 3Output:3 / 2 /1The requirements described in this question are:give us a binary sort tree

In jquery, you can determine whether a string has values in the following ways, and use the IF else if statement to handle business logic.DOCTYPE HTML>HTMLLang= "en">Head> MetaCharSet= "UTF-8"> title>Ajax filetitle> Scriptsrc= "./js/jquery-1.12.4.min.js">Script> Script> $(function(){ varData= $(".

Removing the spaces at each end of the string is a very common method of string processing, and unfortunately JavaScript does not have these three methods, only we have customized: Step 1th, add members to string Copy Code code as follows: String.prototype.Trim = function () {return Trim (this);} String.prototype.LTrim = function () {return LTrim (this);} String.prototype.RTrim = function () {return RTrim (this);} The secon

In this paper, we analyze the method that JavaScript can not be used in the trim function under IE, which has some reference value for the front design of the web. The specific analysis is as follows: First, the JavaScript trim function has no problem with Firefox: In Firefox under this use no problem, but in IE under the error! In this respect, we can modify: String.prototype.trim

Trim (), TrimEnd (), TrimStart () usage Trim (): Is the string that is obtained after capturing the first match of a character, and the null character that intercepts the first if it is not with a parameter gets the string such as: this.
