替换几个输入值 [英] Replace several input values

问题描述

我正在使用的小型聊天系统具有此功能.用户在键入"shout"之前键入一些文本时(例如:"shout hello！").我只想要你好！"输出(其余的应忽略).当我只有一个命令时，这很好用.但是现在我有大喊"和信息".我尝试使用下面的代码做某事，但是它似乎不起作用:

I have this function for a small chat system that I'm working on. When the users types "shout" preceded by some text (ex: "shout hello!"). I want only the "hello!" to output (the rest should be ignored). This worked fine when I only had one command. But now I have "shout" & "message". I tried doing something with the code below but it doesn't seem to work:

function checkValue() {
var value = document.getElementById("thisinput").value;
  // output text without "message" in front
  if (value == "message") {
  $('#output').html(value.replace('message', ''));  
  }
  // output text without "shout" in front
  else if (value == "shout") {
  $('#output').html(value.replace('shout', ''));  
  }
  // output nothing
}

谢谢！

尝试

if(value.indexOf("message") != -1)
