在javascript中删除两个indexOf之间的字符串部分(Remove part of string between two indexOf in javascript)

在javascript中删除两个indexOf之间的字符串部分(Remove part of string between two indexOf in javascript)

如何从两个indexOf之间的字符串中删除

我有这个jsFiddle

这是我的代码：

var x = "M 178.6491699876038 23.419570090792845 C 183.6491699876038 23.419570090792845 186.47776067057902 30.902823043098138 190.3670728596699 41.19229585251793 L 194.25638504876076 51.48176866193772" ; var c = x.indexOf('C') ; var L = x.indexOf('L') ; var final = x.slice (c,L) ; console.log(final) ;

此代码将导致返回已删除的字符串部分

问题如何在删除C和L之间的部分后返回原始字符串

How can i remove from a string between two indexOf

i have this jsFiddle

here is my code :

var x = "M 178.6491699876038 23.419570090792845 C 183.6491699876038 23.419570090792845 186.47776067057902 30.902823043098138 190.3670728596699 41.19229585251793 L 194.25638504876076 51.48176866193772" ; var c = x.indexOf('C') ; var L = x.indexOf('L') ; var final = x.slice (c,L) ; console.log(final) ;

this code will result in returning the removed part of the string

QUESTION how can i return the original string after removing the part between C and L

最满意答案

只需用零替换原始字符串的那一部分：

var x = "M 178.6491699876038 23.419570090792845 C 183.6491699876038 23.419570090792845 186.47776067057902 30.902823043098138 190.3670728596699 41.19229585251793 L 194.25638504876076 51.48176866193772" ; var c = x.indexOf('C') ; var L = x.indexOf('L') ; var final = x.slice (c,L) ; console.log(x.replace(final, ''));

小提琴

Just replace that part of the original string with nothing :

var x = "M 178.6491699876038 23.419570090792845 C 183.6491699876038 23.419570090792845 186.47776067057902 30.902823043098138 190.3670728596699 41.19229585251793 L 194.25638504876076 51.48176866193772" ; var c = x.indexOf('C') ; var L = x.indexOf('L') ; var final = x.slice (c,L) ; console.log(x.replace(final, ''));
