fuzzy string matching javascript

expressions for matching lookupsParameters:①regexp {regexp}: Regular expression, eg:/\d+/return value:Returns a different result depending on whether the regular expression has an attribute ' G ' or not, and returns {null} if no match is found:The ① regular expression does not take the property ' G ', performs a match, returns a {single match} result object, and the object contains the following properties:Array ordinal: Indicates the

function of regular expressions is Back Reference. In fact, the replace of JavaScript not only performs Back Reference in the first parameter, but also replaces the string, you can also perform backward reference, but in many cases, the backslash (\) and numbers may be used as the marker, while JavaScript uses a dollar ($) and a number as the marker.Copy codeThe

This article mainly introduces the code sharing of the string replaceAll function implemented by JavaScript. This article provides the implementation code directly. if you need it, you can refer to the following: Because the replace function in javascript cannot replace all matching strings, therefore, you need to add

This article mainly introduces JS string truncation function instances. If you have any need, refer to substring () or slice () Function: split ()Function: uses a specified separator to split a string and store it in an array.Example: The Code is as follows: Str = "jpg | bmp | gif | ico | png ";Arr = theString. split ("| ");// Arr is an array containing character values "jpg", "bmp", "gif", "ico", and "pn

replacement text. The first parameter of this function is a matching string. The following parameter is a string that matches the subexpression in the pattern. There can be 0 or more such parameters. The following parameter is an integer that declares the position where the matching occurs in the stringObject. The las

The value of an action string is a common occurrence that a typical developer must face. There are many ways to manipulate strings, such as extracting a portion from a string, or determining whether a string contains a particular character. The following JavaScript functions provide developers with all the functionalit

JavaScript String object1. describes the String object and operations on the String, such as intercepting a substring, searching for strings/characters, and converting uppercase and lowercase letters. 2. definition method: 2.1 new String (Value) constructor: returns a

When using JavaScript to process strings, we often use the replace method. This is a very simple method, which has never been ignored before, today, when I read an interesting small example of the JavaScript language, I didn't fully understand it. I understood the usage of replace, the original replace () method is not as simple as imagined. It is used to replace some characters in a

When using JavaScript to process strings, we often use the replace method. This is a very simple method, which has never been ignored before, today, when I read an interesting small example of the Javascript language, I didn't quite understand it. I understood how to use replace. It turns out that replace is not as simple as I thought. The Replace () method is used to replace other characters with some ch

inconsistent, it will automatically convert the type of the operand in some cases. Consider the following assignment statement: var strA = "I love you! "; Var strB = new String (" I love you! "); These two variables contain the same character sequence, but their data types are different. The former is string, and the latter is object. When the" = "operator is used, jav
