以下是一些具体的用法示例: let str = "JavaScript Substring Example"; // 提取字符串的前5个字符 let substr1 = str.substring(0, 5); console.log(substr1); // 输出:JavaS // 提取从索引位置6开始到索引位置16的字符 let substr2 = str.substring(6, 17); console.log(substr2); // 输出:cript...
Example 1: Using substring letstring ="Programiz JavaScript Tutorials"; // first charactersubstr1 = string.substring(0,1); console.log(substr1);// P // if start > end, they are swappedsubstr2 = string.substring(1,0); console.log(substr2);// P// From 11th to last charactersubstr3 ...
Javascript substring() Examples: We will take a string variable and see how JavaScript substring() method works. var string = "substring method example"; //No parameters passed var substring = string.substring(); console.log(substring); //"substring method example" //Both paramters ...
