This article describes how to delete duplicate characters in a javascript string through code examples. The code is simple and easy to understand. For your reference, this section describes how to delete duplicate characters in a string, no matter whether it is of practical value or not, it is quite good to learn algorithms.

The reason is simple, for the concat function, each operation requires a new variable; instead, the method we use here simply expands the original value

you are doing this type of problem, use the For loop too much, then notice, it is likely that you have been biased. Don't underestimate these things, probably in looking for work and normal development play a big role. Well, not much to say, we have to sum up. Inevitably there are omissions, if you happen to be found, welcome to add or DMS. 1. String conversion String conversion is the most basic requirement and work, you can convert any type of d

The reason is simple. For the concat f

the exec () method The exec () method returns an array containing matching results. If no match is found, the return value is null. Example 5: The Code is as follows: Copy code Var reg = new RegExp ("(\ w +), (\ d +), (\ w +)", "gmi ");Var m1_reg.exe c ("Lili, 14, China ");Var s = "";For (I = 0; I S = s + m [I] + "n ";}Alert (s ); 4.

In the js development process, some functions cannot meet our needs, or do not have the functions we need, so we can expand it ourselves, the Type Functions of personalized javaScript (such as Number/String/Boolean/Array/Date/Obejct) are inherited from the Function. prototype. adding a method to prototype also affects the underlying type functions derived from it. For example: The Code is as follows: Function. prototype. addMethod = function (metho
