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.

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. Rtrim = function (){Re

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 actual development, you always encounter this situation. Or in this case If you are still using select fields from table where like '/%', it is definitely a thankless practice, taking a closer look at the built-in functions of MYSQL is definitely the first priority. I first thought that the trim in the PHP function may also be used in mysql. The answer is yes. You can find it in the MYSQL manual. Of course, you can refer to Baidu. What I am t
