使用indexof（）+ 1函数 [英] To use indexof()+1 function

问题描述

嘿，在ma项目中，我使用了indexof函数来阻止某些单词进入跨越分区。我所做的是我已经在数组中存储了'up'，'go'单词并且使用了indexof函数。它工作正常。我想在'go'字之后阻止（动态）直接的单词。这是可能的indexof（）+ 1函数





var commands = ['up'，'stop'，'down'];



var a = commands.indexOf（val.trim（））;

var b = commands.indexOf（a）+1;







什么是在它错了???

解决方案

你好你必须使用像

  var  commands = ['  up'，'  stop'，' 向下]; 
  var  a = commands.indexOf（val.trim（））; 
  var  b = commands.indexOf（a +  1 ）; 

Hey in ma project i have used indexof function to prevent some words from entering to span division.What i have done is i have stored 'up','go' words in array and have used indexof function.Its working fine.I want to prevent the immediate word(dynamically) after 'go' word.Is it possible with indexof()+1 function


var commands = ['up','stop','down'];

var a = commands.indexOf(val.trim());
var b = commands.indexOf(a)+1;



whats wrong in it???

解决方案

Hello You have to use like

var commands = ['up','stop','down'];
var a = commands.indexOf(val.trim());
var b = commands.indexOf(a + 1);
